Batman Beyond Season 3 Episode 10

Curse of the Kobra (1)

Batman has had his hands full foiling the plans of the mysterious terrorist organization Kobra. After he fails to stop some Kobra operatives from stealing a thermal bomb, Bruce Wayne recommends that he study under Kairi Tanaga, one of his old training partners, in an effort to improve his combat skills. During his training, he becomes friends with the reclusive Xander -- a skilled fighter who is shut out from the real world by his two bodyguards. One evening, Terry sneaks Xander out of the dojo to experience normal adolescent life, where, for the first time in his life, he meets someone who can beat him; Max trounces him at Sentries of the Last Cosmos. The evening is interrupted by some Jokerz, and Xander's bodyguards whisk him away as the scene unfolds. Xander never returns to the dojo, instead resuming his rightful place as the future leader of Kobra. He and his "bodyguards" have nearly completed the serum that will transform humans into reptiles, but he needs only one thing -- Max, who he wants to be his queen.
