Zato-1 (GUILTY GEAR)

A Spanish member of the powerful Assassins Guild, Zato-1 allowed himself to become the host of a symbiotic creature named Eddie (a possible reference to Marvel Comics' Venom or Iron Maiden Mascot Eddie) in exchange for his sight. Because of this, Zato-1 was able to take control of his shadow, and use it as a weapon to gain great power. With this power, he made himself leader of the Assassins Guild. However, as his body weakened, Eddie was able to take more and more control until Zato-1's death at the hands of Millia Rage. Zato was "killed off" after the death of his seiyuu Kaneto Shiozawa. Zato despises all women, due to past connections with Millia Rage. His name is likely a reference to Zatoichi, the blind swordsman/assassin

Zappa (GUILTY GEAR)

Zappa is an unlucky young man, looking for a wife and writing in his diary about his new "disease" he has, which, from his point of view, consists of fainting and then waking up somewhere else, possibly with alarming wounds and fractures and no memory of how he got there. Like Axl in the previous game, he seeks the "Dark Doctor" Faust to cure his paranormal ailment. When entering a battle, he is unconscious, with S-Ko and the other ghosts having control of his actions. These ghosts consist of three giant centipedes, several will-o-wisp-like apparitions that manipulate a broken sword, three gray ghosts, a dark chihuahua-like dog, and a manifestation of lightning called Raou. With the exception of S-Ko (who seems to inflict the most pain to Zappa), Raou and the other apparitions seem to try their best to comfort him when he's depressed or in pain, indicating a degree of loyalty to their host. S-Ko's relationship with him still remains a mystery; however, her relationship with Raou and the other ghost imply they are all scared of her.
In his search for Faust, Zappa encounters several people, most of which he ends up fighting involuntarily, and later finding them unconscious. In one ending, he meets up with Ky Kiske, who arrests him for assaulting an officer (the officer being Ky himself). In his other two endings, he actually finds Faust and fights him (once again involuntarily). In one ending he defeats Faust, and then, after regaining consciousness, sees Faust injured and unconscious. At this point, it is suggested that S-Ko assumes more control over Zappa. In another ending, Zappa loses the fight with Faust, and Faust gives his diagnosis: this disease cannot be cured! He then suggests that Zappa isolates himself until a cure is found.
Zappa gains more insight to his illness in Accent Core Plus. Picking up on the route where he's been jailed (making path C from XX canon), Zappa is mistakenly freed when Faust opens up a door into his cell and disrupts S-Ko. After the usual random encounters, the path splits whether or not the player chooses to return a broken Robo-Ky. Choosing to ignore him, Zappa wanders about until he encounters Slayer, whom tries to directly address S-Ko. Slayer says he is returning to where 'people of darkness' belong, and offers to take S-Ko with him. S-Ko refuses to leave without Zappa. This ending makes Zappa the only human in an alternate world with only monsters. If the player chooses to return Robo-Ky, this path Zappa encounters Faust once again, who knocks him out with aid from Johnny. Upon waking, Faust announces that S-Ko has been exorcised. Zappa laters admits to having known someone was with him all along and feels lonely. He asks that the girl return to him only to have a window in his house shatter open, S-Ko crawling through it in physical form. In one of Faust's endings, Faust claims to have cured Zappa by correcting the thing that attracted S-Ko, his face. The ending shows him with a very abstractly drawn face.
He is named after guitar legend Frank Zappa.

Venom (GUILTY GEAR)

Another orphan raised by the Assassins Guild, Venom became the devoted right hand of Zato-1 when he came to power. Once Millia began to hunt Zato and the parasite Eddie began taking more control, Venom began his quest to save his beloved master. He fights with his own style using a pool cue and billiard ball summons. Venom also seems to be an enemy of Faust, supported by one of the endings in Guilty Gear XX. Venom takes his name from the black metal band of the same name.

Valentine (GUILTY GEAR)

Valentine is one of six playable characters in the new genre of Guilty Gear: Guilty Gear 2: Overture. Valentine is the exact copy of Aria, who is indeed one form of the genocide Gear Justice. Her personality is very small and she only talks to get her motives out and nothing more. Valentine's look sports the fashion of leather and Gothic accessories and also wears an unusual head-gear that resembles very long bat wings. Valentine's motives lead her to be defeated by the prototype Gear: Sol Badguy who was once in love with Aria in the past, but even through this That Man has quoted that there are more Aria copies being quickly reproduced. Her weapon of choice is a bizarre; talking balloon named Lucifero with various amplified magic abilities. Valentine also has the power to brainwash enemies and turn them into her allies (as she did to Izuna's Servants). Despite her simple attitude, Valentine appears to be very wise when it comes to strategy; as seen when, though no one noticed, Valentine sent her Servants to attack the Kingdom of Illuyria; alerting Ky Kiske and Dr. Paradigm in the fact that Ky's wife is the Key ( those born of the Gear Justice) that can open the dimension Backyard where the Cube is held. This distracted Ky and Paradigm from reaching Sin (also a Key). Valentine's true form is a fake version of a Gear as yet her looks resemble an unfinished Aria. Valentine is seen by most fans as a warm up for the not-yet-announced; next installment to Guilty Gear 2.

Testament (GUILTY GEAR)

Testament was an orphan during the Crusades, and was adopted by Kliff Undersn. When he was old enough, he desired to become a soldier in the war against Gears,and was known in the Holy Orders as the Black Knight . The Post-War Administration Bureau found him frustrated as he became mentally depressed, and offered to transform him into a Gear. He accepted, though unlike most Gears he still retained his sense of self. However, Justice turned him against humanity, and he found himself on the opposite side of the war from which he started. Testament also states that he enjoys pudding, while his profile page in the Guilty Gear Bible states that he likes potatoes (this is further evidenced in Dizzy's sidestory in Drama CD Side Black- she and Testament share a potato salad, which Dizzy bought for that specific reason).
At the end of the Tournament, Testament appeared to the winner (officially, Sol Badguy, but this varies depending on who the player was playing as), revealing that it was actually he who hosted the tournament, with the intentions of sacrificing the winner to revive Justice, saying, "All that's required is the blood of one more sacrifice!" However, he was himself defeated, and used his own blood as the sacrifice. Justice was then defeated as well.
Upon discovering that there was another Gear alive, Dizzy, Testament immediately took it upon himself to protect her in her hidden grove, fighting off everyone who came near (much like in the original Guilty Gear, Testament was fought before the "main" boss was). He did this until Dizzy decided to leave, joining Johnny and May of the Jellyfish pirates. (his Story Mode in Guilty Gear X+ has two endings, both of which are doubtful. In one, he and Dizzy decide to stay in the Grove for a thousand years until humans have forgotten about Gears; in the other, he and Dizzy decide to leave the Grove together.)
Testament arrives on the May Ship unannounced with the intentions of visiting Dizzy, only to find that she had been knocked off the ship by I-No. He curses humanity, and storms off to find her. He has three endings: in one (the least likely), he discovers that Dizzy has been killed, fights (and probably kills) Johnny, and vows to avenge Dizzy by way of the annihilation of the human race. In another, he encounters Sol, who reveals that "That Man" has returned and the Post-War Administration Bureau is on the move, he also revealed his respect for Sol as he may feel that Sol is the only one who may understand his nature aside from Dizzy. In the third, he fights I-No and then a Necro-possessed Dizzy, who recovers and tells Testament that her fall really wasn't the crew's fault, and in the end, Testament decides to become more accepting of humans - to a point.
Testament is named for the Thrash Metal band of the same name.

Sol Badguy (GUILTY GEAR)

A lone bounty hunter and former member of the Sacred Order of Holy Knights, Sol has dedicated himself to the extinction of the Gears. At over 150 years old, Sol was involved with the creation of the Gear Project, and he is in fact the prototype Gear. He fights with his sword, Fuuenken (Fireseal), with his fire magic. His real name is Frederick. In Guilty Gear XX Slash and Guilty Gear XX Λ Core, there is another version of Sol , from back in time when the Holy Wars were still raging, called Order-Sol, who fights with a much larger sword. In Guilty Gear 2: Overture, Sol is still free, but now travels with the young Sin, and sports a revamped version of FuuEnKen.

Slayer (GUILTY GEAR)

An ancient vampire who founded the Assassins Guild, he comes out of hiding when the Guild dives into chaos after Zato's disappearance. Cultured and debonair, Slayer enjoys haiku and spends his time with his wife Sharon, another immortal. He also has a personal connection with Gabriel, the president of Zepp, but seems to be acquainted with all of the movers and shakers of the Guilty Gear universe. He has the apparent motive of either observing the cast, or warning them of being targeted by the PWAB. He seems to be connected to Gabriel in some significant way, and seems to know quite a lot about various political affairs, most notably the Post-War Administration Bureau (PWAB). He personally knows "That Man" and that character seems to hold him in high regard since he apologizes to Slayer. He also, apparently, has some connection to Sol Badguy, although this may just be a product of Sol being alive for an extended period of time.
Slayer is named after the thrash metal band of the same name. Five of his attacks are named after Queen songs (It's Late, Under Pressure, Dead on Time, Spread Your Wings, All Dead).

Sin (GUILTY GEAR)

Sin is another of the seven unique playable characters in playable in Guilty Gear 2: Overture. He is son of the king of Illyuria: Ky Kiske, though was left in Sol Badguy's care because of the exploitable fact of his Gear cells may be known to the public. He bears grudges towards his father for neglecting him because of his duties as a king.
Though Sin is at most 5 years old, he has the appearance of tall boy in his late teens- making it hard to notice his rash, child-like behavior. Through Sol's (a knowledgeable man in fighting himself) training Sin has grown into a very strong child- even being able to harness the power of a reddish lightning magic like his father (whose lightning is blue). Sol's teaching also included weapon fighting which even Sin is was able to pass and even now uses a flagpole as his main weapon. Sin's potential is very dangerous when it comes to life; because of his Gear genes he may one day be feared as he can be used for war purposes. Because of Sol's age, Sin usually calls him by the name Old Man.
According to the 50 Question Interview at the GG Overture Materials Collection Book, aside from fighting, the only thing Sol is able to teach Sin is to read and write.

Robo-Ky Mk. II (GUILTY GEAR)

A version of Robo-Ky whose moveset and technical parameters (like attack strength, defense, etc.) can be customized. Unlike the other Robo-Ky, Mk. II is built by and has loyalty to a mysterious scientist, not the Post-War Administration Bureau. Type is secret.

Robo Ky (GUILTY GEAR)

Robo-Ky is not simply one character, but in fact a line of robotic copies of Ky Kiske created by the shadowy Post War Administration Bureau. For some reason, Robo-Ky is often mistaken for the real Ky Kiske and vice versa during the game's story mode, even though his face is obviously metallic, his voice is higher-pitched and robotic, and he constantly blurts out *GIGIGI* or *BZZZT* noises during story sequences.
In story mode, Robo-Ky functions the same in #Reload as he does in XX, but that's where the similarity ends - the revised Robo-Ky contains an entirely different sprite set and movelist from his XX predecessor. With regard to explaining the existence of Robo-Ky from XX, it is simply assumed that he was an early model and that the Robo-Ky from #Reload is "the real deal". This also implies that the other characters have never met the Robo-Ky from #Reload.

Potemkin (GUILTY GEAR)

A massive slave-soldier of Zepp, a floating continent controlled by a military dictatorship, Potemkin was forced into the first tournament by his superiors. However, during the tournament, the government of Zepp was overthrown in a revolt led by Gabriel, his mentor. Once Gabriel was made president of Zepp, Potemkin pledged his loyalty to the new government as a special agent. The mantle he wears was a slave collar used by his superiors to keep him in check. He decided to keep it as a memento of his past. Potemkin likes to draw, but is so strong, he can put four tons of pressure on a pencil with only his fingers. In his free time, he works at a bakery, known by his customers not as a killer, but instead, a gentle baker.
GameSpy in their review of Guilty Gear X stated Potemkin filled the "hulking brute" role in the title, adding that they found his personality unique and entertaining, and emphasized his uniqueness amongst the game's cast.[7] This sentiment was repeated in their review of Guilty Gear X2, noting him as one of "the coolest character designs ever seen in a game", and adding him to be "the heaviest heavy ever conceived".[8] Gaming website Boomtown stated simply "Potemkin makes Zangief from Street Fighter look like a sissy."[9] Some criticism, however, for his voice has been made, with a Netjak reviewer stating "I think he should sound Barry White deep, not like a TI 99-4A running a voice module at quarter speed."

Millia Rage (GUILTY GEAR)

Born of Russian descent, Millia lost both of her parents at an early age. She was thereafter adopted into a nearby Assassin Syndicate, where she practiced in the art of Hi-Deigokutsuipou, or the "Six Forbidden Magics". Using the Sixth Hi-Deigokutsuipou, "Angra", Millia's hair gained the abilities she currently possesses, enabling her to control its movement as well as alter its length and shape at will. Zato-1 practiced a similar technique, the Fifth Forbidden Magic, "Shokusei Kagejin", by sacrificing his sense of sight.
Due to Zato-1's rise in power within the Guild, Millia betrayed her "comrade", sealing him within a dimensional portal. Millia abandoned the Guild shortly thereafter, finding no comfort in the cruel ways of an assassin. The Guild leader eventually escaped, enraged at Millia's actions, leading to an overall hatred of women.
Upon hearing of Zato-1's escape from the dimensional prison, Millia uses the Second Holy Order's Fighting Tournament as a method of tracking down Zato, determined to end his life once and for all. Manipulated much like the rest of the cast, the bloodshed from the Tournament releases Justice from her slumber. However, she is promptly destroyed by none other than Sol Badguy.
Still in search of Zato-1, Millia hears mention of a Gear with free-will. Panicked countries establish another "tournament", with a prize of 500,000 World Dollars to he who captures, dead or alive, the aforementioned Gear. Rage uses this as yet another chance to find Zato. Canonically, the former assassin finally finds Zato, seemingly ending his life. Unknown to her, Eddie takes control of Zato's body thereafter, having been slowly gaining control over Zato since the bonding with its master.
After the "death" of Commander Gear Dizzy, as well as Zato-1, Millia continued living in her familiar solitude. However, it was not long before she received sightings of a being similar to that of Zato's Forbidden Beast, Eddie. Encountering many familiar, as well as new, faces along the way, Millia once again confronts Eddie.
In XX, Millia has three different endings, all of which conclude upon her search for Eddie. In the first, Slayer bars her path just before she is about to confront Eddie. After a fight Millia manages to hold her ground but is unable to defeat him, Slayer "reveals" to Millia that her hair is of the same origins as Eddie, though Millia replies that "[she] knows this better than anybody." In the second ending she manages to defeat Slayer and pass on through to then subsequently kill Eddie; fatigued and relieved, Millia returns to her new life. The third ending is very similar to the second albeit with a much brighter outcome. After killing Eddie, she buries Zato's body, leaving her hair and Zato's blindfold as a memento. She thanks him and leaves.
She is named after power/thrash metal band Meliah Rage.

May (GUILTY GEAR)

A young, cute, and spunky member of the Jellyfish air pirates that is utterly dedicated to Johnny, the leader of the pirates and the man who raised her after she was orphaned. She entered the first tournament in order to bail Johnny out of prison, and fights in later tournaments for his benefit. She fights with a massive ship's anchor, which she is able to swing with ease. It is heavily implied that May is Japanese. (In fact, if Justice defeats May in the GGXX arcade mode, Justice will point out that she is disgusted by the fact there are still Japanese people walking the Earth.) May has an irrational fear of bald people and can sense them from a distance.

Leopaldon (GUILTY GEAR)

Very little is known about this character, the boss of Guilty Gear Isuka. An Arcadia article mentions that he is a good man at heart who somehow manages to control a giant Gear, but otherwise little is known about him, his Gear, or his faithful dog. A killer who shows absolutely no mercy, he is a formidable beast.

Ky Kiske (GUILTY GEAR)

The young, dedicated, and pious chief of the International Police Force, Ky Kiske was made head of the Sacred Order of Holy Knights at age 16 and under his leadership, they were able to bring an end to the century long Crusades against the Gears. He is dedicated to God and works to maintain peace after the holy war. Although he morally sees only in black and white and not in shades of grey, and is easily manipulated by unseen workers from the holy war, he is working to adjust. His dedication to law and order puts him at odds with the free-spirited Sol Badguy, his rival. He fights with the Thunderseal sword and with his lightning magic.
After Ky hears rumors of bloodshed, huge prizes, and the possible resurrection of Justice, Ky Kiske enters a tournament that will select members for a second Sacred Order of Holy Knights. After hearing Justice's last words at the conclusion of the tournament, Ky hears new rumors, these ones of a new Commander Gear that doesn't wish to harm humans. He sets out to find the truth in Justice's final words and the flaws of his own concept of justice. After rescuing a beaten Commander Gear Dizzy and entrusting her to Johnny's care, Ky returns to his normal duties as a captain of the IPF. As soon as he's returned to work, Ky Kiske is thrust into a new conspiracy which includes robot clones of himself, a secret organization, a woman in red called I-No, and Sol.
In Guilty Gear 2: Overture, he has become king of the country Illyuria through an overwhelming support at an election. He then finds out that the Gears have begun mysteriously vanishing, and his kingdom is under attack by a mysterious force, he turns to Sol for help by sending out a "Wanted" sign with his face on it, demanding him brought to Illyuria. Sol and Ky maintain a friendly relationship in Overture, and, like Sol, he also sports a new sword, called Aquila.

Kliff Undersn (GUILTY GEAR)

Kliff was the founder of the Holy Order and wields a massive sword known as the Dragonslayer. A hero of the Crusades, having clashed with Justice multiple times, he became a great mentor to Ky Kiske and personally scouted Sol Badguy to join the Holy Order. He is the foster father of Testament, whom he found as an orphan during the Crusades. In Accent Core Plus, it is revealed that he may have fought Testament as a Gear while he was under the control of Justice toward the end of the war. Although the player has the chance to confront Testament in the first Guilty Gear, it is unknown if their meeting again is actually canon. He still maintains a great deal of prowess in his old age, and has the uncanny ability to transform himself to a younger state, if only briefly. After the first Guilty Gear, Kliff passes away likely due to old age and the stress of the tournament. He appears again in Guilty Gear X: Plus, Guilty Gear XX, and Guilty Gear XX: Accent Core Plus as a secret character.

Justice (GUILTY GEAR)

The original Commander Gear, Justice had the power to control all other Gears, which she used to wage war against the human race. Ultimately she was brought down and exiled to a dimensional prison by the Sacred Order of Holy Knights. However, she was freed by Testament, but was quickly defeated once again, and finally destroyed by Sol Badguy. Justice is the final boss of Guilty Gear, is absent from Guilty Gear X except for in Guilty Gear X: Plus, and returns as a secret character in Guilty Gear XX and Guilty Gear XX: Accent Core Plus.
It is unofficially hinted that Justice's appearance is based on the anime Tekkaman Blade. Justice is stated to officially be the mother of Dizzy in the Guilty Gear XX: Side Red and Black drama CD. A battle between the two characters begins with Dizzy asking Justice why she feels familiar or who she is, hinting at a mysterious connection between the two. A victory by Justice in the arcade mode of Guilty Gear XX results in her telling Dizzy, "It's time for you to go to sleep."

Judgment (GUILTY GEAR)

Judgment was originally Raymond, a mad scientist working on the remote island of Isene and exploiting its inhabitants, trying to create a living weapon that would surpass even the gears. He believed his work was the work of God. Raymond is devoured by Inus, a dark king of the underworld, who is subsequently killed. This allows Raymond to take control of Inus's power, transforming himself into Judgment. However because Inus wished to remain dead, Judgment was subsequently consumed after being defeated.

Johnny (GUILTY GEAR)

Johnny is captain of the airship May Ship and leader of the Jellyfish Pirates. His first appearance was in Guilty Gear as a non-playable character in May's ending, and he became a playable character in Guilty Gear X. Johnny is a compulsive womanizer; his entire crew, including May, is composed of young women. He is protective of Dizzy, defending her from bounty hunters in Guilty Gear X and I-No's attack in Guilty Gear XX. He fights with a wood-handled Japanese sword and uses the Iaidō style of swordsmanship. His outfit and his long hair indication he's a reference to Johnny Winter.

Jam Kuradoberi (GUILTY GEAR)

Jam Kuradoberi is a master chef, and longs to create her own restaurant, but lacks the means to do so. She seems to have terrible luck in this endeavor even once she gets it off the ground. She's a fairly docile character, and also relatively unimportant during the beginning arches of the storyline. However, during XX, Jam's ability to wield Ki becomes a very notable aspect. She can be described as a bit of a flirt, as she has hit on both Bridget and Ky in her story.
Jam is wandering about, allegedly having heard rumors about mystical ingredients to be found at "The Devil's Living Place," where Dizzy resides. When she runs into Testament, she claims to be looking for "ingredients," which he mistakes for "atonement" (because the two words are homophones in Japanese). After her battle with Testament, she goes on to fight Dizzy, who thinks that she's trying to eat her (or simply kill her). In one ending, Jam is able to get the ingredients she sought for, which were allegedly unknown to mankind. In the other, the field is burned down during the battle. In both, she defeats Dizzy, and probably leaves on friendly terms. According to information given in Guilty Gear XX, she later claims the bounty for Dizzy's defeat and uses the money to start her restaurant.
Jam's restaurant, which is now up and running, is burned down by a mysterious figure who dresses very similar to Ky Kiske. She engages the said arsonist at the scene, and then the story branches out. In one path, she accuses several people of being the arsonist, and then finds another the false Ky Kiske, who is revealed to be a robotic version known as Robo-Ky; two endings come from this. In one, someone — presumably from the Post-War Administration Bureau — is revealed to be watching her using a crystal ball, and concludes that her fighting data would be useful for their next "simulation project" (there will not be a Robo-Jam in the works, though this may also foreshadow Robo-Ky Mk. II). The other has the Robo-Ky call in reinforcements (in the form of MORE Robo-Ky's) which Jam fights a few of, until Ky Kiske appears to intervene. Jam wards off a brainwashed May while Ky disposes of the aforementioned Robo-Ky's. Jam then offers to share a picnic with the Holy Knight, arguing that food is the cure for a bad mood, after the whole arson issue is cleared.
Jam's other path has her meet I-No, who gives her a false list of bounties, including Venom, Johnny, and Millia Rage. After fighting I-No again and finding out that the bounties are false, she tries to make it up to the aforementioned victims by cooking for them. Venom and Millia Rage, unable to sit anywhere near each other (and drunk on top of that), end up slinging insults until they fight. The ensuing battle destroys Jam's new stall, which she has started up since she lacks the finances for a new restaurant.
Jam is later able to rebuild her restaurant through multiple loans, but is unable to pay them off. To get the money to do so, she sets out to advertise her restaurant and runs into several of the cast members, who she tries to make work at her restaurant but only Bridget lost and had to work there.

Izuna (GUILTY GEAR)

Izuna is another playable character who made his debut in Guilty Gear 2: Overture. Along with Dr. Paradigm and Valentine, Izuna also comes from the plane Backyard. Izuna is a Japanese fox spirit who himself was exiled to the Backyard. Unlike most spirits of his kind, Izuna gained a physical form through the power of his will. Izuna states that "There are more physical spirit demons like me, but were brainwashed by Valentine". He is a very skilled swordsman and has certain magical abilities. Izuna is also the one to teach Sol Badguy and Sin how to use the tactics of the Ghost and Master Ghost system in the game as well. Most fans believe Izuna's looks were taken off of Slayer, though this is not likely because various interviews with Daisuke Ishiwatari he exclaims that Izuna along with Valentine, Dr. Paradigm, and Sin are all new children (creations) of his.

I-no (GUILTY GEAR)

One of That Man's servants and apparently a time-traveler, I-No appears in the Postwar Era approximately two weeks after the events of Guilty Gear X. She attacks Dizzy and sets the various fighters of the era against each other, seeking to help That Man's still-unrevealed plans. However, throughout points in Accent Core Plus, it seems that she's trying to help what she thinks his plans are instead of his plans for sure. She fights with an electric guitar, both using it as a bludgeon and playing it to create deadly sonic waves. She also wears a stereotypical pointed witch's hat that can fire projectiles out of a hidden "mouth." She is the primary antagonist and boss character of Guilty Gear XX.
In Guilty Gear XX, one of her victory poses has her playing a guitar solo similar to one of the solos featured in the Eddie Van Halen's instrumental piece Eruption. In the game Guilty Gear: Accent Core Plus it is revealed in one of I-No's Endings that she is killed by Baiken, an event that is paralleled in one of Baiken's storylines.

Holy Order Sol (GUILTY GEAR)

Order-Sol is an alternative past version of the original character, which has him clothed in a garment similar to that worn by Ky Kiske. Sol was indeed a part of the Sacred Order of the Holy Knights, this is a take on what Sol looked like during that time and how he fought before beginning to use his now-trademark sword, Fireseal (or "Fuuenken"). This form also shows a glimpse of Sol's true Gear form (where he sports a pair of demonic wings and a tail) when performing the original version (without the aid of Fuuenken) of his Overdrive move, Dragon Install. His EX Instant Kill is "All Guns Blazing". It's technically the original Instant Kill of Sol Badguy from the original Guilty Gear.
Order-Sol uses a different attack system than the other characters, though similar to the attack charge system from Guilty Gear. He uses a Charge meter with 3 levels. By pressing half-circle back along with Dust (quarter-circle back as of Accent Core), Order-Sol will begin charging his meter. At each level, all of his command techniques gain extra strength or new properties. He also possesses an attack that can be used while he is charging, similar in appearance to a Burst, providing knockback and a small amount of damage, which ends the charge. His moves seem like prototypes of his former moves, but with extremely different looks and effect, like the Bandit Revolver Prototype and his Gun Blaze. The Dragon Install also changes from an ability that augments Sol's strength and speed into a special move of its own. It can only be done in level 3 of the Charge Meter, and when performed, can be linked to Sekkai, which is a combo move done like the Deadly Rave by Geese Howard. Sekkai can only be linked after the Dragon Install's Stagger, but can do tremendous damage. When the full move is performed and the enemy's life is below a certain level, Sol transforms into his true Gear form and unleashes an 11th hit One hit kill which is similar to Sol Badguy's "Napalm Death" . Also, his Tyrant Rave 'Omega' (different from the 'Beta' version of the common Sol) changes effect with the Charge Meter.
Order-Sol uses an all out style when he fights, when Sol Badguy is a little more refined. This could be relevant to his higher experience as Sol Badguy.
Order-Sol improved in Accent Core, with new Overdrives, longer range and a faster rate of charge that requires no timed button presses.
Thus far, he has only appeared as a playable character in Guilty Gear XX Slash, Guilty Gear XX Accent Core, and Guilty Gear XX Accent Core Plus.
In addition to being playable, Order-Sol has a "boss mode" version that appears as a final boss of Guilty Gear XX Slash's Arcade Mode. In this form, his speed and power are increased, and he gains a vastly improved form of the original Dragon Install called "Flame Distortion". This move increases Sol's strength and speed even further and improves many of his special attacks for a limited period of time. While Flame Distortion is active, Order-Sol constantly regenerates health, and his attack speed increases to the point where he can easily chain together Overdrive techniques.

Eddie (GUILTY GEAR)

After fighting Millia, Zato-1 falls to his injuries, and the parasite Eddie (エディ, Edi?) takes control of Zato's now decaying body to seek out a new living host to control. Eddie replaces Zato-1 from GGXX onward with regard to both the story and the selectable characters. His name is a reference to Eddie the Head, the mascot of the heavy metal band Iron Maiden.

Faust / Dr. Baldhead (GUILTY GEAR)

Once a kind and very talented surgeon, Faust became a ruthless murderer after losing a young girl in surgery. After horribly killing scores of people and being imprisoned, Faust was given a second chance after the first tournament. He first decided to atone for his crimes by taking his own life, but he learned that the girl's death was actually caused by a third party. Donning a paper bag on his head and taking his oversized scalpel, Faust seeks out the truth about the girl's death while dedicating himself to saving as many lives as he can.
Faust has been commonly noted by reviewers as a standout character in the series due to his appearance[2] and unconventional in-game behavior.[3] Gaming website Boomtown described him as "a nine-foot tall guy with spastic limbs and a paper bag over his head", noting him as one of "the strangest and most entertaining host of characters in any fighting game to date."[4] IGN compared him directly to Soul series character Voldo, adding "has enough humorous patterns to keep you entertained for days."[5] Game Chronicles reviewer Mark Smith shared the sentiments, praising the representation of Faust's personality in his moveset.

Dr. Paradigm (GUILTY GEAR)

Dr. Paradigm is yet another of Guilty Gear 2: Overture's seven playable characters. He is one of the sealed Gears from the dimensional plane Backyard during the era of the Genocide Gear Justice in the Crusades. This action was done so Justice could not control his mind using her Commander Gear abilities. Dr. Paradigm was later released when the 100 year war was over. Dr. Paradigm is a strongly skilled magician with a fairly large book of magics. How strong his magic lives up to is not known, yet he can cast very helpful and dangerous magic in a manner of seconds. Past this his knowlegedable and very bright mind is not to be taken lightly as he's even more knowledgeable than Sol Badguy himself. Dr. Paradigm has a protective bubble around him in which it seems permanently around him. Paradigm also has what seems to be a small fairy girl flying around him but no one knows exactly what she is there for. Paradigm has a reasonable hate for humans yet will not attack them, for he wishes "not to make the same mistake as these filthy humans".
Paradigm seems heartless to those at some times as seen when has no hesitation to kill Ky Kiske's wife. He'd rather end things at the moment than to rather fight Valentine and her forces. Paradigm is a bit prejudiced at moments when it comes to Gears and humans as he would pick the Gears' side anytime. Paradigm is useful when it comes to magic. He even freed Ky from Valentine's imprisonment spell Valentine had cast on him. Paradigm can even reverse the brainwashing ability of Valentine with a single spell. He is also the only one besides That Man and Axl Low to call Sol by his original name: Frederick.

Dizzy (GUILTY GEAR)

The details of Dizzy's birth are not known; all that is known for certain is that she was found as an infant roughly three years before the events in Guilty Gear X, by an old couple with no children of their own to depend on. The other villagers became afraid, however, since Dizzy appeared to age from being an infant to apparently being in her late teens in three years. This was compounded when she discovered, one day, that she now had wings and a tail. Dizzy was now identified as a Gear—essentially, a living weapon of mass destruction, and a hundred-year war against Gears had just ended five years ago. Dizzy's foster parents hid her in a grove in the woods, but she was soon discovered and subjected to abuse at the hands of her captors. She quickly escaped, however, and the government issued a 500,000 World-Dollar bounty for her death.
From there, Dizzy came under the protection of Testament, a Gear who had served under the Command Gear Justice. Testament fought off most of the bounty hunters, and if any managed to overcome him, they were quickly beaten back by the immense power of Dizzy herself. She was eventually defeated by the bounty hunter known as Sol Badguy. However, he spared her life, and the bounty fell to Jam Kuradoberi, who used it to create her restaurant. Dizzy was then discovered by Johnny and May, who "rescued" her and invited her into their crew.
A few weeks later, Dizzy was on the deck of the May Ship when she was suddenly knocked off by I-No. She fell 20,000 feet, and the impact caused her to become possessed by Necro. Under no fault of her own, she then laid waste to several other characters until she was "cured" by Faust.
Dizzy's mother, it turns out, is Justice, which is revealed in the drama CD Guilty Gear XX: Side Red And Black,[1] as well as comments on the CD by Dizzy's actress, Kazue Fujita. Dizzy can perform a variation on Justice's Gamma Ray overdrive, as well as the Michael Sword attack (in her "EX" Mode in GGXX).

Chipp Zanuff (GUILTY GEAR)

Chipp Zanuff, a former drug trafficker, was a youth who struggled to live life on the streets of America. Chipp often sold illegal substances to many other addicts and corrupt organizations like the Mafia, so Chipp had become an avid dealer. Chipp's job was not a safe or comforting one, and he soon gave in to the enticing (but mind altering) drugs that he sold for trade. Business had been going as usual, but it seemed a complication had put Chipp into a situation that lead to him fleeing from the Mafia. Chipp had become outnumbered and, it seemed death had come early for him, but as if from nowhere his pursuers were quickly dispatched, and in front of Chipp stood a man clearly different from the others. He revealed his name as Tsuyoshi, and his next words would change Chipp's outlook on both life and the sins he had committed. Tsuyoshi offered Chipp into his care, which he gratefully accepted. To clear the youth's mind, as well as start a life of honor and repentance, Tsuyoshi trained Chipp in the art of Ninjutsu basics, to which he quickly adapted, and they lived peacefully together until an assassin syndicate ordered Tsuyoshi's killing. Chipp, filled with rage, attempted to pursue the culprits responsible, entering the second sacred order tournament in order to get him a lead in his travels.
Chipp enters the second order tournament to carry on his quest of vengeance. His ending, while non-canonical, is the only ending in the mainstream games to feature Tsuyoshi's face, and it is revealed he has a purple scar over his left eye, ninja attire, a large nose, and a mustache. Chipp believes that even though Justice was evil, she deserved a second chance, just as he did. He then leaves, spending all the time up until the discovery of Dizzy training in the wilderness.
Afterwards, Chipp starts off his quest once more only to be interrupted by Dizzy possessed by Necro, who happened to have just fallen from the May Ship. After swiftly getting away he encounters other characters including Bridget, Ky Kiske, Faust and Eddie. The story splits from there, Chipp either encountering Venom who after his defeat (by Chipp of course) makes a deal with Chipp; if he becomes President, he may use the guild to his needs, in the second ending he meets Slayer who taunts Chipp; Chipp vows to become stronger in order to defeat Slayer and in the final ending he gains knowledge of the Post-War Administration Bureau after defeating Robo-Ky and learns of his role in their plans. In other player's story lines, he is often a brainwashed enemy and again Necro's first unfortunate target.
Chipp's gimmick of being a "ninja" of foreign descent is the reason he utters words like "sushi," "sukiyaki" and "Fujiyama geisha" -- stereotypical Japanese words that would be known to a non-Japanese—during and after battles. However, since the release of Λ Core (Accent Core), Chipp uses real Japanese words for his attacks.
Chipp's name is derived from Chip Z'nuff of the American Hard Rock band Enuff Z'nuff.

Bridget (GUILTY GEAR)

Despite the name and appearance, Bridget is actually male. He was born in a village where the birth of twins of the same gender was considered bad luck, and hence his family named and raised him as a girl. When he became older, he decided that he would prove his worth and his pride by becoming a bounty hunter. He is given a fake list of bounties by I-No, sending him against many of the other fighters. He fights with a yo-yo and Roger, his mechanical, over sized teddy bear.

Baiken (GUILTY GEAR)

During the Crusades, the nation of Japan was destroyed by the Gears. Following this, those of Japanese descent who still lived were declared cultural treasures and placed in special colonies. However, the Gears attacked even these colonies. During one attack, the young Baiken, after watching the death of her parents and losing her right arm and left eye, saw standing among the Gears their creator: "That Man." From that point, she swore revenge, training herself in the use of the katana and dedicated herself to hunting "That Man" down. (Baiken was a hidden character in Guilty Gear but became a normal character in the later installments.) Armed with a katana, she also has many hidden surprise weapons within the sleeve of her severed arm: a Japanese mace, a fireworks cannon, a bladed fan, a chain rope, a hook, a claw, and a spear. Her design is based on Himura Kenshin and Hayashi Fubo's Tange Sazen

Axl Low (GUILTY GEAR)

Axl Low is a time traveller. He comes from the 20th century, over one hundred and fifty years before most of the Guilty Gear storyline. His main goal is to return to his own time period, mainly because of his desire to return to his girlfriend, Megumi. For this reason, he seeks out various means, and is continually attempting to solve his time slipping mystery. He seems to know Sol Badguy as Frederick from the 20th century.
Axl enters the Sacred Knights Tournament in hopes of finding a way to get back to his own era. He was apparently led to believe that the winner of the tournament could have a wish granted them. In the second game, Axl is wandering about, looking for Faust, in hopes of being cured by a doctor of such skill. He encounters various people on the way, and fights them, chalking it all up to bad luck. Then he meets up with Sol Badguy. After this, the path splits. In one ending, Axl fights Kliff Undersn and Justice, and then realizes that he's been thrown back in time once again. In the other (more likely) ending, he battles Faust, and then is diagnosed with involuntary timeslipping. Faust blames this on there being an alternate version of Axl in existence.
Axl meets up with I-No, among other people, while wandering about. As is the case with many other characters, I-No is the catalyst that causes the events that follow. In one of his three endings, he ends up fighting a future version of himself. In another, Axl fights with Zappa, and afterward begins to wonder how Megumi is faring. In the third ending, he meets up with "That Man" and finds out from him that Raven is the cause of his timeslipping, and it is implied that Raven is the alternate version of Axl that was diagnosed by Faust. This allegedly has something to do with actions performed by Axl later on. Perhaps more light will be shed on this in later games. Interestingly, since the three endings have nothing to do with each other, and don't contradict each other in any way, it's entirely possible that they all happened. His appearance appears to be based on Axl Rose.

Anji Mito (GUILTY GEAR)

Anji Mito is among the few people born of Japanese descent. Because of this, he is protected by the government since full-blooded Japanese are an endangered race. While there are those who accept this lifestyle, Anji doesn’t - he compares acceptance of government to living in a zoo's cage. To regain his freedom, he escaped from his colony and pursued That Man for answers for his ever-curious mind.
No one knows exactly how he heard of That Man and the Gears themselves, nor do they know how he came to possess the Zessen fans. It is implied that Anji stole the Zessen, which had been stored in the Japanese colony, before escaping.

A.B.A (GUILTY GEAR)

Created atop a mountain home named "Frasco", A.B.A is an artificial life-form, or homunculus, the creation of a scientist who lived within Frasco. However, before her 'birth', the aforementioned scientist was taken away by the military, which was planning to use his skills for unknown reasons. When her eyes opened for the first time, A.B.A found herself alone within Frasco, and lived the first 10 years of her life in total isolation.
Escape from Frasco was not impossible. Nevertheless, A.B.A quickly realized that she had no knowledge of how to exist outside of her home. To find relief from her sadness, she began to collect keys of all kinds, as they represented the opening of a bold new world and an escape from imprisonment.
While roaming outside one day, still tired of her isolated life, A.B.A stumbled upon an ancient relic known as "Flament Nagel". It was love at first sight, as the war relic was shaped like a key, A.B.A decided to keep it as her partner; she renamed it "Paracelsus". Her new goal was to acquire an artificial body for her newfound partner, whom she refers to as her spouse.

Yugo Ogami (BLOODY ROAR)

Yūgo Ōgami is a young wolf zoanthrope on a quest to uncover the circumstances of his father's death. His father, Yūji Ōgami, was a mercenary said to have died in combat in a South American country. Yūgo also seeks the mercenary Gado, the sole survivor of Yūji's combat unit.[1] Yūgo and Gadou eventually meet in a secret Tyron Corporation laboratory, where Gado reveals that Yūji was a zoanthrope who fought against the Tyron Corporation's mind control experiments and conversion process. Yūgo then promises his father that he will destroy their enemies with the powers that he inherited from him.[2]
After the fall of Tylon, Yugo hides his Zoanthropy and takes up a career as a boxer. He is not truly alone, as he took under his wing a boy he found during the destruction of Tylon. The boy had no memories and nobody to take care of him, so Yugo took it upon himself to adopt him as his brother and named him Kenji. One day, five years after the incident with Tylon, Kenji is mysteriously abducted by a strange person. He assumes this is a sign that Tylon might be resurfacing and decides to fight back and rescue his younger brother.
Yugo becomes the leader of an NGO (Non-Government Organization) called the W.O.C.(World of Co-Existence). Their goal is to build a bright future for both humans and Zoanthropes alike. But a mark known as the 'XGC' appears on his body. The 'XGC' will eventually end his life and end the lives of others who are afflicted if he doesn't find out how to stop it. He sets out to uncover the truth.
A representative of the Zoanthrope tournament visits Yugo. Prior to his visit, a group of men and a woman had attacked Yugo as part of a test to show the representative his legendary skills. Yugo had worked out for himself who they were working for. The man gives him an invitation to the tournament. Yugo accepts, wanting to learn more of the 'bad' activities going on behind the scenes.
Yugo has been racking his brains over the violence occurring. While out investigating the incidents he heard rumors of a 'Black Shadow'. Also, that the name of this 'Black Shadow' was Nagi. This name he'd heard before. He was sure she had been a victim during the incident with the XGC a year before and was still in a hospital somewhere. In order to learn the truth, Yugo sets out on a journey.

Xion (BLOODY ROAR)

The 'XGC' mark gives Zoanthropes the power to possess the Tabula of a Thousand Beasts, which has been sealed to prevent calamity breaking free and gathering into one being. He is able to become an 'unborn' (an animal that doesn't exist yet) Xion wishes to break the seal of the Tabula to revive the power that lies within. His goal is to completely exterminate the Zoanthropes with the 'XGC' one by one. Once the Tabula is integrated, the world will change its form. Xion walks his path alone to free the Unborn from a distant dimension. He killed his sister, whose heart was attached to the 'trivial' world. He sees it all as a useless waste that must be eliminated to create a new and better world.
When Xion awoke, he realised he'd done something terrible. He'd been a mad man, consumed by a dark presence. He remembered the man who'd defeated him told him to survive, and a woman passing saying that he couldn't regain but he could compensate. His hands were dirtied with blood, but he had not been in control and never meant his actions. It was easy to think that he could make up for the pain he'd caused but he thought it would most likely end up with his complacence. But he had to try, as long as he lived.
Xion reflected upon the incident a year ago. A woman stood before him; she was not a Zoanthrope. She was saying something to him but he couldn't hear her words. What stood before him was the truth, and he needed to remove it from his path. Other Zoanthropes want to live together with humans, but that had nothing to do with the Unborn. After revealing golden wings from under his fur, over the woman's fallen body, he muttered that humans were making a mistake to try to defeat him. Though he had doubts that his words at the time were actually his own. All he knows now that Zoanthropes are coming before him once more to defeat him. The battle has just begun.

Uriko Nonomura (BLOODY ROAR)

Uriko Nonomura was kidnapped by Tylon as a child to be used in an experiment that created super beast soldiers. She was brainwashed and converted into the body of a woman that stored the power of a synthetic transformation known as 'Werechimera'. While brainwashed she was forced to fight against her mother and her friend, Alice, whom she had helped to escape from Tylon. But it was thanks to their efforts that she was freed from Tylon's influence and she changed back to her normal self, returning with her mother and Alice home.
Five years on from her ordeal in Tylon, Uriko is a junior high school student. One day, when she returns home from school, she sees a group of men surrounding her mother. The leader easily floors the powerful Mitsuko and they abduct her. Uriko, angry, decides to transform and defeat her mother's abductors. Unfortunately, the experiments that were performed on Uriko those five years ago has left lasting effects on her ability to transform. The force is too much and her transformation stops halfway in the form of a bobcat. She is too weak to fight these foes, they'd easily defeated her mother who is known to be one of the strongest Zoanthropes. In order to gain the strength she needs, she seeks out Long, who is a renowned martial artist.
After rescuing her mother, they return to a peaceful life. Though Uriko is easily bored with this lifestyle. She was saddened that Kenji would not play with her anymore. So she turned her attention to what Alice and Yugo were doing. They were investigating the XGC mark. Looking for something to keep her occupied, she decided to go investigating too.
The subject known as 'Prototype Uranus' was a test body equipped with a strong attack ability, high alertness, agility in gravity control and can maintain acid mucus inside the body. She is the strongest third generation man-made Zoanthrope - formally the ace card of the now defunct company, Tylon. She was an incomplete ultimate weapon - an evil that could cause massive destruction. Because of its immense power, it could not be controlled. That is why a lesser version, 'Uranus', is created, where the power is more suppressed...
The representatives of the Zoanthrope Kingdom were expecting to see a monster but instead saw a sweet faced, drooling girl asleep in her bed. A gong was banged to wake her up. Uriko asks who a person is and is given a business card (in English). He then explains they are hosting a fighting tournament and she is invited to participate. Uriko asks if he means an athletic game, though he is dumbfound by her question. After that she goes back to sleep where he is forced to try for three long hours to wake her back up again but to no avail. The idea next time is to tempt her with food.
When Uriko was walking through town, she noticed some grade schoolers prodding something. When she came closer upon the scene, she saw they were poking at a little white dog. She shouted at the children, who upon hearing her loud voice, scattered in all directions. Out of gratitude the little dog leapt up onto Uriko and began to lick her face, then biting the hem of her clothing, began to pull her off somewhere. Uriko was unable to resist and followed. She asked the little dog what its name was and checked to see if it were on its collar. But it didn't have one, so she decided to name it herself. After much deliberation, she called the little dog Pakupon. She followed little 'Pakupon' off on an unknown adventure.

uranus (BLOODY ROAR)

From the shadows appears a figure before the fighting Zoanthropes. She is the strongest Zoanthrope, the Chimera, created by Tylon when they converted Uriko. Uranus was cloned from Uriko and became a perfected form of both her Chimera and her synthetic body. She is known to be the perfect zoanthrope, but cannot hold her chimera form very long, so she tends to go without transforming. Uranus has the fate to be both the wife of the God of the Sky and the mother of the God of Time, Cronos.

Stun / Steven Goldberg (BLOODY ROAR)

Steven Goldberg, was as a young, zealous scientist working for the multinational group, Tylon. He believed his research would contribute to saving people's lives. In the same year that he joined the company, another young scientist by the name of Busuzima entered work there and the two would become good friends, and also, good rivals. Though, when Steven discovered the evils behind the company, he became a part of one of Busuzima's experiments and converted into a man-made insectZoanthrope. Because of how unstable the experiment had made his genetic structure, he could only survive on a special stabilizer developed to retain his body. Feeling betrayed, Steven (now going by the name 'Stun') plunges into despair over losing his human form. Slowly, his mind and body decayed though his heart yearned for revenge.
A year ago, Stun fought against Busuzima after turning him into an artificial Zoanthrope in a cruel experiment. However, when he faced Busuzima, he was unable to kill him because he remembered their lost friendship. His revenge had been quelled by his still rational heart. After the ZLF fell, Stun disappeared into the shadows, forced to drink the blood of animals to stabilize his decaying body. He lives now out of sight - a solitary figure hiding his deformed form from the world. Eventually the mysterious 'XGC' mark befell him and the power that came with it began overloading his unstable body. The violent energy raged within him, often surfacing in sharp pains that would sometimes rendered him uncontrollable or unconscious. He knew he'd become a monster if he didn't act soon. Jenny, an old friend, appeared before the agonised Stun and whispered to him that his pain was caused by the power of other dominant Zoanthropes with the 'XGC' mark, and unless they were beaten, he'd completely lose all reason - and he should not hesitate if he wanted to retain his pride as a man.
Stun awakens to the sounds of voices, confused by his surroundings. His memories are badly distorted - a complete blur. As he considers where he is, he takes notice of what the voices are saying. The unknown people recognise he is awake, and that his lost cells have successfully been restored, though they don't believe any of his memories were saved. 70% of his body cells, including brain cells, were already damaged before he was captured. Now though they observe that this body is stable unlike his former body. Though they take note of tissues within his brain that couldn't be eliminated - tissues referred to as the 'black box'. It worked like a flight data recorder. They'd wanted to remove them to eliminate memory recall but were unable to. The scientists are a part of a project to mass produce Zoanthropes, and agree Stun will be a good candidate for data collection. He laughs at them. They become very uneasy.
A year after the XGC incident, Stun lives out his days struggling with great pain in his body. Losing patience, he wonders how long he could live with his enhanced body this way. If he was to have a long life, he needed a way to try and preserve himself. He received information of a Shinto oracle who could seal the power of the beast. Uneasily, Stun decided to seek out the oracle, knowing that there wasn't much time left. It was a single ray of hope that he prayed would end his suffering.
