Except he really doesn't require as much as people seem to think. If people fail to learn the character it's probably because they focus too much on banana game and don't realize that Diddy's basic mechanics are really, really good [almost unfairly so, I'd like to add]. His spotdodge, shield, jab, grab, rolls, tilts and walk / dash are
summa sumarum pretty much the most overpowered set of basic tools any character has in this game.
Mr.0, Nietono is the #1 Olimar in Japan because he has better accomplishments than Brood does by far. By now he has proven that countless times, by outplacing him as well as beatin players Brood loses to [Yui, Rain, Shu ... pretty much all the great players from the east of Japan].
