Ogun (comics)

Ogun was a fictional character of Marvel Comic books and a foe of Wolverine. His first appearance was in Kitty Pryde & Wolverine #2, published in 1984.

Ogun was a martial arts master who acted as Wolverine's mentor. Very little is known of the character, but he was apparently a mutant who could possess and control minds through some type of psionic means. His reflexes and reaction time also appear to have been enhanced beyond the range attainable by normal humans.

At some point in the past Ogun fell from the path of honor and became a criminal enforcer for the Yakusa. Ogun mentally possessed the X-Men Kitty Pryde and was aiming to turn her into an assassin. Wolverine was eventually forced to kill Ogun.

Later Ogun somehow managed to return to life and mentally possessed host after host and attacked Wolverine. Wolverine figured out that to destroy Ogun he need only destroy Ogun's enchanted mask.
