*sigh* people, just ask "how do i unlock this character?" in the questions section!
You need to be in adult gohan's dragon universe for at least the second time. After you have unlocked videl and goten go to kami's lookout and beat piccolo.
When the dabura fight appears go to the mountains in the northern area and you should find a scene with vegeta after this scene go and fight dabura, when you have beaten dabura gohan should go after vegeta instead of buu.
Defeat vegeta and then go to the red dot BUT before you go there press R1 you should find a plains spot near cxentral city. After the scene with supreme kai he bacome unlocked
