The Silver Samurai also known as Kenuichio Harad first appeared in Daredevil #111 (July, 1974). He is one of the few mutants that retained their superhuman powers after epic storyline M-Day, only to have Wolverine track him down and sever his hand at the wrist with his claws during a battle. When last seen, Silver Samurai was kneeling on the floor cradling the bloody stump where his hand once was.
Aronofsky might not be directing but I have to say I am very happy with the choice of director James Mangold, who crafted a brilliant western with 3:10 To Yuma a few years back. More to come.
