Its only supposed to be like that for bowser, since the only way he gets it off is if he has lower percentage
On the GANON and BOWSER suicide moves-
Bowser's victory is determined by controller port. If Bowser's Controller port is a higher number than the opponent, Bowser wins. If lower, it goes to a SD. This is why they declare Bowser the winner.
Ganon's suicide CANNOT RESULT AS A VICTORY IN THE GAME ever. With Ganondorf, you would want to be the LOWER CONTROLLER PORT Number. If Ganondorf is the lower controller port number, the game goes to a SD. If Ganondorf is the higher number, the opponent will get teh victory according to the game.
Kirby/Dedede is always a tie.
I think Ganon/Kirby/Dedede should be Inui/M2K's suggestion of 1 stock run off with a 2 minute timer. Ganon shouldn't win, as he never gets credit from the game as a win in any scenario (unless its a lava thing at norfair)
