For some reason, drawing Mario's face is always a pain for me. Otherwise Mr. Videogame is pretty simple. He's gamings eternal optimist, and he always seems to be in a great mood no matter how often misfortune happens upon him.
It's actually pretty rare to see him get angry, and when he is, he usually has good reason for it(except in those soccer games, where he seems royally ticked off for no reason). In Brawl, for example, Mario actually smiles less often than Captain Falcon...But I'd be pretty ticked if I was the most notable character in a game and could be defeated more than anyone else in the story mode.
Mario, the plumber that makes a living rescuing princesses and crushing tremendous foes beneath his worn shoes.

Mario's firepower is so amazing it doesn't seem to generate it's own light for some strange reason( >> ). Also it hardly looks like fire at all...Hmmm...
