Pajiba has released some character info from Wolverine 2 – take a look. Some spoilers below!
Logan: After getting into trouble in his native Canada, Zen, Japanese man, arranges for Logan’s release and offers to answer questions about his origin if he’ll accompany him to Tokyo.
Zen: He finds Logan in jail in Canada and makes him an offer he can’t refuse – to come to Japan and learn about his origin.
Shingen: His late father was the Master of the Hand, but rather than allow Shingen to take on the role, he killed himself and left the Hand masterless, hoping that they would choose Logan as their new Master.
Mariko: Shingen’s daughter. Shingen has arranged her marriage to the corrupt Noburo, but when Logan saves her life, they fall for one another.
Kenuichio/Samurai: He’s the illegitimate son of Shingen, but Shingen refuses to acknowledge him as an heir. He’s also an expert Samurai, and he attacks Logan several times as a “Silver Samurai” with electrified armor.
