Nobody but Undertaker should do it. Kane came into WWE as an opponent for Undertaker, it's only fitting that he should go out the same way.
Maybe they could have their last match at Wrestlemania, where both Kane and 'Taker retire. The match would go to a no contest, or either 'Taker or Kane does something in the match that 'destroys' the both of them.
I have to go with Undertaker as well, but it cannot be a single's match, it has to have some significance. But I don't want it to be a match that if you lose you have to quit, because that's pretty obvious who would win.
I wouldn't mind a casket match or a burried alive match. Or even another Inferno Match, that would be great.
Casket Match for sure. I'm not a big fan of the "I Quit" matches myself. A very poor gimmick for a match if you ask me. This news has guaranteed me to watch at least one more WWE PPV/episode. Thanks a lot Kane.
Probably have to go with the undertaker aswell. it's be nice if Kane got a Wrestlemania match against the Undertaker as his last match but that probably won't happen unless he gets a big push between now and then. I'm sure it'd be an epic match though, especially if it's casket/hell in a cell/inferno.
however if I had to say there was a second choice (beings that Undertaker is the obvious) why not go with Randy Orton? I mean he's already called the "Legend Killer". So wouldn't that almost be like a pat on Kanes back by indirectly calling him a Legend by having Orton finish his career?
