|Appeared in||Batman Beyond: Curse of the Kobra|
Kairi Tanaga is a warrior who taught Zander.
Kairi emigrated to America, and settled in Gotham City. She opened a stall in a fish market, but behind it she operated a secret dojo for serious students of martial arts.
Her students included Zander, the leader-in-training of Kobra, who had been genetically engineered from scratch. Recognizing his lack of a normal education in morals, Kairi tried to instill in Zander a respect for the warrior code of Bushido, emphasizing honor and non-aggression.
Other students included Terry McGinnis, whom Bruce had sent to her to brush up on his martial arts training. Kairi trained him hard for several weeks, during which Terry began to develop a friendship with Zander.
However, Zander later revealed himself as Kobra's leader, and took part in the cult's plot to replace humans with genetically spliced reptile hybrids, and to destroy most of Gotham by triggering a volcanic eruption.
Saddened that she had failed to instill values in her student, Kairi boarded the Kobra's hovercraft and rescued Terry and Max, before engaging Zander in battle. The ship sustained heavy damage, and began to descend. Terry urged Kairi to follow him and Max, but she was cut off by falling debris. She told them to abandon ship, and reminded Terry of a lesson she had given him about keeping his guard up. She perished in the crash, along with Zander and the other cultists.
Bruce, Max, and Terry observed a moment of silence at the dojo in honor of Kairi's sacrifice.
