You cannot play as Mewtwo in SSBB. However, the glitch below can allow you to play, at least for a brief period, as Bonsly.
My Glitch: Me and my cousin were in brawl. My cousin was Ice Climbers and I was Lucario. he got a party ball and two pokeballs came out. He threw his first and got Gardevoir. I threw my pokeball at him while he was in the shield. It backfired and it flew back at me and out came Bonsly. I threw Bonsly at him while he was in the middle of the edge of the shield and I was suddenly playing as Bonsly!
There is no glitch to play as Mewtwo in Super Smash Bros. Brawl U cant even use mewtwo. Only in super smash bros. melee.
no sorry
Only as a trophy.
no
Mewtwo is no longer a character so you can't fight him in ssbb.
you cant get mew two on ssbb you can only get him on ssb and on super smash flash
I don't think you can but....maybe if you hack it mewtwo might join brawl
The reason is that lucario was popular in Pokemon Diamond and Pearl and mewtwo is forgotten now. It's a shames
Mewtwo is the bets boss. when u go to fight him hew is really tough, so be prepared! No wait its not mewtwo its tiabuu.
no you cant SSBB is only WII
No you can't play as Shadow on ssbb, Shadow is only an assist trophy.
you can not unlock him even by hacking Au contraire, mister previous poster. If you have access to Ocarina, a cheating application, then you will be able to do a character model replacement hack. Most downloads for Mewtwo usually end up in replacing Lucario. -TB
