Are there two different Kanes

Answer 1

No, what would give you the idea there is. There's only one "Big Red Machine" There actually were 2 different actors. The original actor was actually undertakers real brother. He got hurt so they hired the current actor to play Kane. The original actor wore the long sleeve because he has a tattoo of a naked lady on his arm. So yes, there were 2 actors, but only 1 character.
