What about the SA-X?
It'd be a cool idea to do like zero suit, press a certain button when starting, to change to Dark Samus. Though that might make Samus too OP, I mean more then she already is.
Watch This Custom Characters Brawl I found on YouTube
I like the lil Custom Movesets for Samus, and although its just Charizard in disguise, i still like the idea of Ridley being in Smash
Problem with someone thinkin' Samus is overpowered. Outta the two bounty hunters in Smash Bros., she's gotten the worst end'a things on the tier list. 'Cept in vBrawl, but not by much.
And on that note, the only broken character is Meta. Snake is nearly there as well, but he can still be counterpicked... and doesn't have a retardedly bullshit gimp game.
