Silver Samurai (X-Men Movies)

IchIrō Yashida is the true main antagonist of The Wolverine.

Biography
During the Nagasaki bombing in 1945, Yashida was saved by James "Logan" Howlett, AKA the Wolverine, at a prisoners of war camp where Logan was being detained. In subsequent years he became head of a powerful Japanese company, as well as having a son, Shingen, who in turn had a daughter, Mariko, whom he became more attached to rather than Shingen. Many years later, one of his granddaughters servants, Yukio, was sent to get Logan to meet Yashida as he was dying. When Logan got to Japan, Yashida offered to take his eternity away from him so he could become immortal. Logan refused the offer. Yashida said then he must protect his granddaughter, Mariko, from her father, as he had entrusted his fortune to her and not Shingen. Yashida's doctor, a woman known only as "Viper", injected a robotic parasite into Logan, taking away his healing factor. However, later that night, Yashida apparently died.

It was later revealed Yashida had faked his death and was in a Silver Samurai armor. He battled Wolverine and cut off his claws. He then started to extract his immortality away but was stopped by Mariko and then permanently killed by Wolverine.
