Name: Sol Badguy Real Name: Frederick Height: 184cm Weight: 74kg Origin: United States of America Weapon: Outrage Mk.II Formerly a scientist named Frederick, he conducted research in magic theory alongside Asuka R. Kreutz and Aria. He was involved in the "GEAR Project," which aimed to biologically enhance humanity, but in 2016, he was betrayed by Asuka and forcibly converted into the first GEAR. After losing his humanity, he developed a device to suppress his GEAR cells, successfully maintaining a near-human appearance. He then took the name "Sol Badguy" and began working as a bounty hunter. He harbors a deep hatred for Asuka, the creator of the GEARs, and has pursued him for many years. Personality Gruff and lazy. A man of few words, he speaks only the bare minimum. He is poor at explaining things or expressing emotions, preferring to show his intent through actions rather than words. Because of this, he is often perceived as self-centered and violent, but he actually cares for his comrades and those close to him. Long-time acquaintances accept him as a "handful but reliable" guy. He is involved with almost every character in the series, for better or worse. He hates putting in effort and dislikes talking about his past. Appearance A large man standing 184cm tall. He has long red hair tied back. He wears a goggle-like device on his forehead. His outfit is a rugged combat suit based in red and black. He wields the massive sword "Outrage Mk.II." His overall design evokes a "rough bounty hunter" and a "battle-hardened warrior." Despite being a GEAR, he maintains an appearance almost identical to a human.

Name: Ky Kiske Height: 178cm Weight: 58kg Origin: France Affiliation: United Kingdoms of Illyria, First King Weapon: Thunderseal A genius swordsman who displayed talent from a young age, becoming the Captain of the International Confederation of Knights at just 16. He fought as a hero for humanity during the Crusades and continued peacekeeping activities to protect mankind afterward. Initially, he held a rigid conviction that "justice is protecting humans," but meeting Dizzy—a GEAR who desired coexistence with humanity—forced him to re-examine his own sense of justice. He eventually married Dizzy and had a son, Sin. He later became the King of Illyria, working toward a society where humans and GEARs coexist. Personality Extremely serious and upright. He has a strong sense of justice and considers helping the weak a matter of course. On the other hand, in his youth, he was quite inflexible, showing strong aversion to anything that disrupted rules or order. Since becoming King, he has come to understand various perspectives and has grown into a more flexible individual. However, he remains a hot-blooded man at his core and still occasionally acts on emotion. Appearance A slender, tall young man with blonde hair. He wears blue-themed attire befitting a knight and royalty. He carries the Thunderseal sword. In STRIVE, he has a more mature, kingly presence than before. He has blue-green eyes and is a classic, clean-cut handsome character.

Name: Asuka R. Kreutz Alias: That Man / The Gear Maker Height: 167cm Weight: 58kg Date of Birth: November 10 Weapon: Magic A genius scientist and sorcerer who is deeply intertwined with the very history of the GUILTY GEAR world. He was one of the researchers who studied magic theory alongside Sol Badguy and Aria and was the central figure who pushed the GEAR Project forward. By creating the GEARs, he triggered the global "Crusades" and came to be treated as one of the greatest sinners in human history. He was once Sol's best friend, but the events surrounding the GEAR Project led to him turning Sol into a GEAR, creating a long-standing feud between them. In STRIVE, he surrenders to the U.S. government, bringing a major resolution to his years of conflict with Sol. Afterward, Asuka heads into space, engaging in the peculiar activity of broadcasting "clear numbers." Personality Highly intellectual and soft-spoken. He is a gentlemanly figure who generally speaks politely, but even without malice, his "rational statements based on his own logic" can often baffle those around him. While a genius as a scientist, his physical abilities are extremely low. He gets out of breath from even slight exertion, so he leaves manual labor to machines of his own making. He desires world peace, but his thinking is very unique, giving him the aspect of a "genius who does outrageous things out of goodwill." Appearance 167cm tall. A slender, small-statured young man. He wears white-based robes and coat-style clothing. His hair color is nearly white. He has an intellectual look with glasses. Since he uses magic, he deploys numerous magic circles and bits during combat. His design is that of an "intellectual mage," contrasting with the physical powerhouse that is Sol.
