is a superhero appearing in American comic books published by Marvel Comics. She is a female ninja of Japanese origin and a supporting character of the X-Men, particularly associated with Wolverine. Originally conceived of as a love interest of Storm, the characters' relationship was relegated to subtext after Marvel Comics' editor-in-chief Jim Shooter mandated that no same-gender couples could be depicted in comic books during his tenure at the company. Yukio has appeared in The Wolverine, Rila Fukushima, and Deadpool 2, portrayed by Shioli Kutsuna. Publication history Yukio's first full appearance was in Wolverine #2 (September 1982), created by writer Chris Claremont and artist Frank Miller. Character history The X-Men's first encounter with Yukio occurred when Wolverine had his struggle with Shingen Yashida, father of Wolverine's girlfriend Mariko Yashida.

During their altercation with Viper and Silver Samurai, Storm found her powers inexplicably going out of control, endangering her life. Yukio knocked Storm into the nearby bay, enabling them to escape from the Silver Samurai. (These events had actually been brought about and influenced by the mutant villain Mastermind, who was conducting a revenge campaign against the X-Men at the time. He was also responsible for the subsequent halting of Wolverine's and Mariko's wedding). Storm, inspired by what she called Yukio's "madness" and lust for life, changed her image dramatically and adopted a new look: a mohawk haircut, studded collar, and black leather clothing. Yukio later met up, once again, with Wolverine to help him fight the ninja master Ogun. She developed a rivalry with the X-Man Gambit: Both being thieves, they often tried to steal the same
