Ogun

Ogun was a ninja and at one time Wolverine's mentor. He was a strong telepath and has been shown to match Wolverine in agility and fighting skills. During the 1930s, Ogun became a Captain in the Japanese Imperial Army and met Wolverine for the first time in Shanghai, China while Logan was a sailor. Impressed by Logan's bravery and defiance, Ogun offered to train him in the martial arts at the Ogun Ryu Dojo in Kanazawa, but Logan declined.

Years later, Logan remembered Ogun's offer and he went to Japan to better learn self-discipline. There, Logan spent years under Ogun's tutelage, Ogun and Logan became friends, and as time went on Logan regarded Ogun as a surrogate father. During this training Ogun taught Logan how to balance his human side and animal side in order to become a great warrior, he also taught him about the Art of the Samurai and the teachings of Sun-Tzu.

During one of their meditation sessions, Ogun and Logan were attacked by a group of ninja led by the criminal Lord Ugama Hana who wanted reparations from Ogun for wronging him in the past. Ogun told Logan to stand down and he quickly took down all the ninja before facing Hana. Their fight was brutal and the warriors were evenly matched, but in the midst of the battle Ogun decided to drop his sword and taunted Hana, who impaled him as a result. Suddenly, Ogun's eyes flashed red and he started to laugh, he then removed the Hana's sword from his stomach in front of an horrified Hana who then begged him for mercy, but Ogun beheaded him. On that night, Ogun revealed to a horrified Logan that he had discovered how to beat death.
