It used to be link, but recently I've started to really really like Samus. I think she's got a lot of potential, though Nintendo seems pretty intent on ruining everything that I like about her.

Toad. Captain Toad, Toadette, Toadsworth. They are the little guys of the Mushroom Kingdom, and even though they are small and meek, they still do what they have to do even under the worst circumstances.

Luigi. Have you guys seen just the utter SWAG of that SUAVE motherfucker? The fucker even had a year to himself, nothing can beat that.

Kirby followed by Luigi and then Samus.

*Looks at username*

Wario.

Little Mac.
He's the underdog, takes a beating but never gives up.

I like quite a few of the Pokemon characters but besides that series my fav Nintendo character would be... Kirby. (>^o^)>

Link

Mario is by far my favorite Nintendo character. Can't help but love that little pudgy guy

Bowser from the Paper Mario and Mario&Luigi series, he is so damn funny.
