Sol Badguy is the main character and namesake of the Guilty Gear fighting game series. By initial appearance, he is an aloof bounty hunter anti-hero who fights with an oddly rectangular sword called Fuenken, or the Fireseal. He will rarely ever put much effort into his fights, a fact that angers Ky Kiske in particular. However, his brash and somewhat abrasive exterior conceals a genius and emotional depth. He has dedicated his life to the destruction of Gears, a race of magical bioweapons that plunged the world into a hundred-year war known as the Crusades. In particular, he shows a particular zeal to destroy their creator, an individual known only as "That Man". Sol is also a fan of Queen, and his rival in the series is Ky Kiske.
