Maybe this is old news, but me and some of my friends found this out last night. Anyways, Zero Suit Samus has an infinite move, where she can repeatedly "chain stun" certain characters in Brawl. There was a Brawl tourney at a local video game cafe place I hang out at a lot, and we saw someone use this "move" at the tourney yesterday. Basically, she stuns them over and over again, and the other player can't do anything about it, and eventually you can just knock them off the stage somewhat easily once the stun moves add up to a high percent.
I think this only works for Fox, Falco, Bowser, and Wolf.
Here's a vid that shows Zero Suit Samus's infinite:

We all laughed about it last night though.
