KGBeast(Anatoli Knyazev)

KGBeast, whose secret identity is Anatoli Knyazev, is a villainous assassin who got his training from "The Hammer", a top-secret KGB cell. KGBeast's strength has been enhanced cybernetically, so in addition to mastering numerous martial arts, he is proficient in the use of every existing deadly weapon. Throughout his time in Gotham, KGBeast has fought heroes like Batman, Robin, Huntress, and Suicide Squad. During Blackest Night he is resurrected and recruited into the Black Lantern Corps, and after Flashpoint he joins the Suicide Squad (realizing he can't beat them), so at times he also goes toe-to-toe with other villainous characters. When DC relaunched their characters for the New 52 in 2011, KGBeast got a new backstory, and he was recreated once again as "The Beast" for DC Rebirth in 2016.
