Dr. Mario is not playable in Brawl.
you can't. but you can in melee.
No
You start off with him.
Dr. Mario isn't in Super Smash Bros. Brawl, probably because he's almost exactly the same as Mario.
You cant. Sorry.
There is no Dr. Mario I'm pretty sure, they even say it on a SSBB wiki page
he is not a playable character in ssbb
Finish classic mode with Mario then dr Mario will appear take him down to unlock him this only works in super smash bros melee.
There are no looney tunes characters on SSBB.
This character doesn't exist in ssbb.
Unfortunately, Dr. Mario was not included in Brawl probably because he is very similar to Mario in practically every way. The developers likely decided not to put time into programming him in and instead worked on other, more unique characters.
no
