Kyogre – This is apparently some huge whale Pokemon, he sprays water way above the stage from what I saw and was near useless in that regard. The water does no damage, it simply does knock back like Mario’s FLUDD. Kyogre himself does damage and knock back if he touches you though.

Piplup – Piplup uses surf and is basically the new Marrill, but more effective. Surf seems to drag you off the stag much better than Marrill ever did. Still not that great of a Pokemon though.

Munchlax – Munchlax loves to eat items. As soon as an item appears he dashes to it real quick and eats it. I don't think he eats other pokeballs though

Bonsly – Apparently this stupid looking tree thing is called Bonsly. He doesn't do anything but wander around as far as I can remember, but you can pick him up and throw him at your opponents for some really big knock back.

Groudon – Groudon looks like you expect. He’s really big. He doesn't seem to really move very much if at all from what I remember, but if he touches you he does massive amounts of damage and knock back. Pretty cool visually I suppose.

Torchic – Torchic stays in place and Fire surrounds him. He is basically the Wheezing of Brawl. Does quite a bit of damage.

Chikorita – Same thing as in melee, but it seems harder to DI out of.

Snorlax – Snorlax does the same thing as in the other games, but seems to have even more knock back this time around.

Goldeen – Goldeen is again seemingly useless, HOWEVER with the new swimming feature added maybe we will see something happen if Goldeen flops into the water. But I doubt it.

Gardevoir– Gardivor basically comes out and makes a big circle force field around itself and floats around the screen. A lot of people didn't know what this Pokemon did, but it basically acts like a huge reflect zone on projectiles if they hit the circle. I'm not sure what happens if you use a projectile while inside of the circle though.

Latios/Latias – These Pokemon come out of the pokeball and immediately fly off screen. Then they fly VERY quickly back onto the screen across the stage doing big knock back and big damage. They are very fast, but it seemed like they missed more often than they landed their attacks.
