SSJ3 Bardock vs Golden Frieza
So, in the recent Xenoverse 2 game,
Spoiler:
Bardock becomes an SSJ3 against Mira, but before even becoming a normal Super Saiyan, he's able to deal with Mira just fine.
If you've read the spoiler, here's some more info, Mira was tooling Majin Buu in the original Xenoverse game, which makes him roughly Goku SSJ3 level from the Buu Saga as of that point.
This also means that Bardock increases even more with each transformation.
With that said, who wins this bout, taking all of that into Consideration?
