Katana (Tatsu Yamashiro (山城 タツ, Yamashiro Tatsu)) is a superheroine appearing in American comic books published by DC Comics. First appearing in 1983, Katana is a samurai warrior whose skill with a sword allows her to fight for justice as a superheroine. Her tragic backstory includes the death of her husband, Maseo, whose soul becomes trapped in her blade, the Soultaker. Katana has been part of various DC Comics superhero teams, including the Justice League and Birds of Prey, but is most commonly associated with the Outsiders, a team of heroes hand-picked by Batman to act as his personal black ops team, handling riskier missions. Of the character's first appearances, one critic has noted, "The idea that a superhero would wield a sword which caught the souls of the wielder’s victims was not very superhero-y. But Katana was from the start a rough and tumble character happy to use throwing stars as weapons (even if she usually used the flat of her sword otherwise)."
