Dr. Mario isn't in Super Smash Bros. Brawl, probably because he's almost exactly the same as Mario.
he was switch with just normal Mario in super smash bros brawl
no, but you can unlock Dr. Mario in Super Smash Bros. Melee by completing Challenge Mode with Mario.
sadly no there is no cheat for dr. eggman. i beat the game and you cant unlock eggman.and im no perfessional. if you dont believe me go to youtube and type how to unlock all the characters on sonic smash bros and surely that will help you.
Dr mario is not an unlockable character in brawl.
No body knows
You can't. He was removed from the game.
Dr Mario, Pichu, Roy, Young Link and Mewtwo
In the first one it was ness, luigi and captain falcon for me, in the second one it was dr mario, in the third one its sonic and meta knight.
Finish classic mode with Mario then dr Mario will appear take him down to unlock him this only works in super smash bros melee.
unlock dr. mario, luigi, falco, and young ink
