Anyway, for King K. Rool, I think if he is playable his alter-ego he takes in each of the "main games" could come into play.
For example, King K. Rool would be his normal self when normally playing and his B would be the crown throw. Pushing Over-B would change him into Kaptain K. Rool and he fires a cannonball that if it doesn't hit, can be picked up and thrown. Up B can be Baron K. Roolenstein using his jet-pack (he could fly irc) to launch into the air, and finnaly Down B can be King Krusha K. Rool and do a big slam attack.
Too bad Koach K. Rool will never be an outfit…
So...good idea? I haven't played DKC 3 or DK64 in awhile, so I dunno if those are viable attacks for said ego.
