2. Nintendo Has No Idea What to Do With Him

In all of the Mario Sports games, characters have cool abilities that are related to their personalities. Mario will shoot fire, Donkey Kong will throw bananas, and Waluigi will... make a wall? Flood the level? It never makes any sense, and is usually amazingly overpowered because of it. They gave him a freaking whip in a soccer game. A whip. It's awesome, because it shows that Nintendo has no freaking clue what to do with the character.

no time for Waluigi sorry! LOL.

HAHA, so true

Actually his wall is pretty good, it allows you to make a big shoot.

Banging Daisy? Probably. But she's the resident slut of Mushroom Kingdom (or Sarasaland, whatever). Hell, Nintendo didn't try to hide that in Strikers Charged.
