If I Remember Correctly, You Should Unlock Him By Beating Adventure Or Classic With Every Basic Character..?
Huh? I have no idea what you're talking about, but Mewtwo is in Melee only. Mewtwo is not in the original or Brawl.
Of course it's Mewtwo!
No.
Mewtwo is only in Super Smash Bros. Melee. He is not in Brawl
That's easy just simply play another melee match whoever is the winner will fight mewtwo.
You can't. Mewtwo is only in Super Smash Bros. Melee.
You can't. Mewtwo only appears in Super Smash Bros. Melee.

Although you aren't being specific whether it's Melee, the original, or Brawl, the only game that you can unlock Mewtwo in is Melee(for gamecube). To unlock him, just keep fighting enemies.
Play the game for 50 hrs or play with four players(human players) for 5 hrs in melee.
