So, is Waluigi the worst Nintendo character?

[Super_Boom]

I don't follow Mario titles terribly closely, but has Waluigi ever appeared outside of spin-off or sport titles? It seems to me that he's characterized equally poorly as Daisy, the Babies, or the Toad characters (as in, not at all), and his design is certainly more interesting than any of them.

Honestly though, I'm surprised he's important enough to get his own thread.
