Shingen Yashida was a Japanese Yakuza crime boss who disgraced his family name by attempting to kill his own daughter, Mariko for his father's business empire.
Shingen Yashida is the son of Ichiro Yashida and father of Mariko. He is first seen training his martial art students in a dojo at the Yashida family home. Shingen wanted to take over his father's business to prevent it from going bankrupt, and arranged a marriage between Mariko and Noburo Mori so that he could gain political access. However, these plans were foiled when he found out Yashida had arranged for Mariko to inherit his company, since it would prevent him from gaining control of the company as well as enabling Mariko to avoid marrying Noburo. Offering the corrupt Noburo money in exchange for helping him, Shingen sent the Yakuza after Mariko to kill her.
The Yakuza clan brought Mariko to Shingen, who attempted to kill her before Viper and the Black Clan intervened. Viper stabbed Shingen in the neck with a poison knife, but he survived by jumping into a pond, and then putting on a samurai armor. Later on when Wolverine is about to remove the parasite that was preventing his healing factor from his body, Shingen prepares to attack him, but Yukio fights back and defends Wolverine just long enough to remove the parasite and recover. Shingen was unable to inflict any lasting injury on Logan, who decided to spare him and let him live with the fact that he tried to kill his daughter. Shingen attacked Logan and stabbed him a final time, and at the same time Logan stabbed Shingen with his claws, surviving his injury with his healing factor. Before dying, Shingen asked Logan what kind of monster he was, to which Logan said he was the Wolverine.
