It Is Possible That Super Smash Bros. Melee Is Not A Fully Registered Nintendo Game. Now The Reason I Think This Is Because I Happened To Come Across This Same Question. Well I Studied This Question Trying To Get Info Off Of Nintendo.com In Result It Did Not Pick Up That Melee Was A Game. It Said (sorry we did not find super smash bros. melee). Now This Is Just A Hypothesis But Also People Have Told Me That Nintendo Decided That Lucario Made A Better Substitute For Mewtwo So Mewtwo Was Taken Out. Either Way Still Sadly Mewtwo Was Taken Out :(.Finally I'd Like To Say I'm Not Quite Sure Why Pichu Is There But I Hope This Gave You Some Ideas About This Sad Situation But I Have To Say Nintendo Is Excellent.
No mewtwo is not in the game super smash bros. brawl
mewtwo is not in super smash bros. brawl however mew is a trophy character
Mewtwo and Roy are included as DLC in Super Smash Bros. for Nintendo 3DS/Super Smash Bros. for Wii U. Mewtwo and Roy are already in the game in Super Smash Bros. Ultimate. Mewtwo and Roy are not in Super Smash Bros. Brawl but are in Melee.

No. Mewtwo is not in Super Smash Bros. Brawl. If you want a character that resembles Mewtwo, then that would be Lucario. Though Mewtwo is in Super Smash Bros. Melee.I'm afraid not. And, no, there is no hack or secret strategy to get it.
