try it with Mew-Two, should work
no. you either earn them or use a gameshark. the passwords are for "*character name* combo" moves. they're all the same thing: they use the 3 basic attacks of their significant character, and then finish with a stronger attack, varying which character. for example, Sonic combo finishes with a shot attack, while Shadow's finishes with the basic heavy attack (Chaos Nightmare) as far as colors go, though, there are no passwords. passwords are only for combos =(
Battle, and at the same time, resist the character during the event. If your opponent uses a projectile attack, block or (depending on the character you are using) deflect the projectile when you have the chance. When you come across a Super Mushroom (not to be confused with a Poison Mushroom) or a Starman get them. (King Dedede is rated the most powerful character in the game, so I would recommend that you use him, even if he is not your charcter)
you have to battle 7 times and finish your pokedex
battle lots of trainers
