KGBeast (Justice League Unlimited)

As strong as he looks, KGBeast has power of Bane and the skill level of Deadshot and would be a dangerous foe to come across. Known for his unerring drive to succeed, KGBeast cut off his own hand in order to escape capture by Batman. Outfitting his stump with a machine gun, the KGBeast continues to operate as a supervillain, most recently as a member of Grodd's Legion of Doom.

History
KGBeast appeared in the Justice League Unlimited episode, "Kids Stuff", where he first clashed with the Justice League while robbing a bank with Blockbuster, Cheetah, and Copperhead. They were soon interrupted by Batman, Superman, Wonder Woman, and Green Lantern. KGBeast opened fire with his gun,chasing Batman down a dead-end hallway,but Batman rolled out of the way,hurling a batarang.KGBeast watched it spin away,then roughly seized Batman by the front of his cape and was about to fire his gun into Batman's head,but was defeated after the electric Batarang came spinning back into KGBeast,shocking him to his knees,and was then punched by Batman down the hallway,where Wonder Woman roped him with her Lasso of Truth. Suddenly, the adults of the world disappeared to another dimension, including KGBeast, his partners in crime, and the Justice League. KGBeast studied his new surroundings,but showed the least reaction to the change of events than any of his partners in crime. KGBeast later joined Gorilla Grodd's Legion of Doom. When Lex Luthor was escorted by Grodd to the Legion of Doom's swamp headquarters,KGBeast is shown standing next to Gentleman Ghost. Later,Luthor briefly listens to KGBeast,who is talking to Metallo about his gun-hand. KGBeast is one of the only two Batman villains who are members of the Legion (the other being Blockbuster). In two other episodes,KGBeast made background appearances sitting at the Legion's meeting table. He was present when Luthor overthrew Grodd and made himself the new Legion leader.He later sided with Grodd during the mutiny against Lex Luthor,marching to Grodd's right as Grodd advances on Luthor,supporting Grodd by aiming his own gun against Luthor. KGBeast was later seen during the battle between the two warring factions of villains supporting Luthor and Grodd,walking through the battle,firing random rounds into any potential attackers. After Giganta was beaten,KGBeast walked alongside her,firing his gun at unknown villains, but his ultimate fate is unknown.
