I'd say I liked Bee Mario the best, followed by Cape Mario and then finally Raccoon Mario.

Metal Mario??

come on that was one of the coolest Power ups everrr..=p

I didnt like Metal Cap so much. The greatest thing Mario has going for him is his awesome jumping abilities. Metal Mario seriously hampers the jumping around. It wasnt totally useless just took a lot of the fun out for me when you have the metal cap on.

The flying mario cap from mario 64.

METAL MARIO!!!!

Cape then Bee Mario

ive only played a few mario games.

but my fav one is the cape.

I'm going to have to go with Metal Mario because of the music.

8-bit Mario from Paper Mario Wii was cool, too.

Tanooki Heck yeahhhh!!!!!

cape, racoon and fire Mario in this order.
