X-Men Origins: Wolverine.

Watch it to know more about the origin of Wolverine.
Maybe it differs from the real origin, but I will take it as the real.
Haha.
Wolverine is a name given by Morgan's lover.
His claws weren't metal initially til the baddie general transforms him into some metallic creature.
The romance element of the show also fits in quite well.

Hugh Jackman so fit man.
HAHA!
