* Flashbacks to first fight with Freeza, fight with the androids ( even though I wasn't there ), fight with Cell, you vs Beerus ( I didn't win either but I got him to use 68% more of his power ), second battle with Freeza, you vs Hit, ToP.*
That wasn't cannon. Akira Toriyama stated that the DBZ movies are not part of our timeline. So that technically didn't happen. Also Beerus said SSJ2 Vegeta was more fun to fight than SSJ3 me.
We need more people to watch Dragon Ball Super; Make me the main character; How about something that won't piss off the fandom? Wait, what's Dragon Ball Super? How 'bout someone who didn't die in five episodes and never came back? Give Vegeta; A new form; I swear, Broly, if you say something stupid. Make Broly cannon; Y'know, last time I yeeted you into oblivion but now that sounds like a good idea... If Freeza gets to kill your dad.
