What is your favorite Mario universe character?

Iggy.

EDIT: Mario, Luigi, and WAAAAAALLLLUUUIIIIGIIIII.
I like any enemy that is related to poison or the grape soda from NSMB.

The Koopalings, Bowser, Luigi, Toad.

My is Luigi, because he wears green (my favorite color) and the game "Luigi's Mansion" made me like him more.

I also very liked Koopa Troopa because I loved turtles when I was young.

I'm very surprised that nobody in the history of this thread said any of the characters from the Wario games...
