I think you have to defeat Mario with King Dedede in 20 standard brawls.
Bowser comes unlocked
NO.
You can't.
u cant
to unlock Bowser jr. all you to do is play as Bowser in classic mode 1000 times
the brawl mario and sora battle to remainde 2 unlocked bowser
No,Bowser Jr is not in brawl but the original bowser is.
No
Im afraid that you cannot unlock him as a playable character. Bowser's Final Smash, however, lets him turn into Giga Bowser and rampage the field for a short amount of time.
Giga Bowser is the final smash of Bowser so strictly speaking yes.
No.
The only way to play as Giga Bowser is to use Bowser's final smash in Super Smash Bros Brawl.
