Discuss the other guy Mario saved Peach from here

Snake: Otacon, there's a gorilla wearing a tie here. He's huge.
Otacon: That's Donkey Kong. As you can tell, he's got strength to spare.
He may be king of the jungle, but he lives in a house just like you and me. And he seems pretty smart--well, for an ape, anyway.
The Donkey Kong who fought that epic battle with Mario was this guy's grand-father.
Snake: That was a long time ago. What about this Donkey Kong? Does he get along with Mario?
Otacon: Nope, they're still at it. Seems like they're always competing in something--kart racing, sports, you name it.
Snake: A chip off the old block...

errr...i havent even played him yet >.>
is he any different besides having the worst final smash in the game?

Oddly enough, I have to argue his Final Smash isn't the worst, so long as you have sense of rhythm...it just could have been something a lot cooler.
