object. Yukio once framed Gambit for a crime she committed. Yukio is also part of Professor X's secret information network of humans and mutants, known as the Mutant Underground (not to be confused with Cable's Underground). After the death of Mariko Yashida, Wolverine sent his adopted daughter, Amiko Kobayashi, to a foster family. He later discovered that her new foster parents were abusive and only interested in the money. Wolverine took Amiko away from them and asked Yukio to raise her. This unofficial adoption was under the protection of the Silver Samurai, now an ally of Wolverine. Yukio trained Amiko in the martial arts and to her own surprise she enjoyed her new role as a mother. When Sabretooth targeted Wolverine's friends and family, he hired Omega Red and Lady Deathstrike to kidnap Amiko. Yukio fought the two, but was overpowered and seriously injured, and left her in a wheelchair. She asked Wolverine to kill her, but Wolverine refused and saved Amiko shortly afterwards. Yukio reappeared and was fully recovered from her previous injuries. She teamed up with Storm again to enter the Arena, a fight club for mutants. In the end, Yukio, Storm, and Callisto took over the Arena. Later, Yukio and Amiko were attacked by Hellverine (a demonic being who had taken over Wolverine's body in order to kill his loved ones) on the behest of Marduk Kurios. Her confusion over the fake Wolverine's behavior earned Yukio serious injuries, but Amiko returned from school just in time to save them both from Hellverine. When Wolverine goes back to Japan to stop a war between the Hand and the Yakuza, Yukio is shown to be once again in a wheelchair due to Hellverine's attack. As part of the All-New, All-Different Marvel event, Yukio is shown running an illegal nightclub in Osaka, Japan when it is visited by War Machine where he asks her about the tech-based ninjas. Yukio states that she cannot say anything if she wants her business to stay afloat. After being threatened with the prospect of having the Avengers storming the place, Yukio points War Machine to a rather big and muscular man in a tuxedo who leaves the nightclub with two ladies entering the car with him.
