yes, of cource it is all you do is go to the park and wait till masquerade comes and win him in a one on one using only darcus bakugan
yes you can in the arena play rules.
Only a classic.
go to "my room" and go to deck. Click on the bakugan and move the arrow keys left or right then up or down to select a bakugan.
you can't Leonidas and the other bakugan evolve in the middle of the game but you have to battle one on one to get evolved bakugan and then buy them
