Thanks to Brawl Central, we've found out a bunch of new Super Smash Brothers information. None of the information below is confirmed.
- It seems that if you "pass" a mini-game on the WarioWare stage, you heal slightly.
- Meta Knight has a Kirby (pink) colored costume.
- Sothe, from Fire Emblem I believe, is an assist trophy. I guess he's supposed to use knives in the game, but doesn't in Brawl. Instead he does a somersault kick.
- NEW MUSIC! Animal Crossing Main Theme, Balloon Fight's Balloon Trip music, and WarioWare Main Theme.
- When you start a match, the background music is displayed.
- As seen on the Dojo, Wario-Man's bike is very fast and it's easy to SD with it.
- More info on Sandbag Item: You beat him up, and items come out as you hit him.
- The WarioWare stage features over 8 minigames, including "Don't Move".
- Bowser and Kirby seem to be getting more and more praise for how much they have improved over their Melee forms.
- More Music Confirmed: Yoshi's Island has songs called "Ending BGM" and "Athletic". Norfair has "Brinstar BGM", "Samus's Theme", and "Metroid Ending Theme". Bridge of Eldin has "Great Bay".
- Snake's Remote Mine (Down Smash) varies in damage from 10-20%.
- Kirby's new Dash Move is named "Break Spin". It's being refered to as the yo-yo attack, but does not involve a yo-yo of any kind.
