He died at the beginning of Deception and came back to Shao Kahn almost instantly. Also, the only reason why I said zombie Shao Kahn was because of Quan Chi's arcade ending. I know that an ending isn't necessarily canon but it could be semi-canon at least.

@Dynamo: I would imagine that Kenshi wants just to help the Earthrealm Warriors to succeed so he helps. I know it's a cop out but it's the way it goes. I think he just came back to Kahn because he had no other choice at that point. In Deadly Alliance he certainly didn't hesitate to underhandedly kill Kahn, which turned out to be just a clone/decoy but still.
