Golden Frieza = god level ba? I'm sorry, I have to be clear when I say god level. I meant God of Destruction level. Not just normal kai Shin level.
Also, I doubt Uub at 10 = SSJ3. SSJ, maybe. Theoretically, his max should be Kid Buu level BUT, considering Kid Buu never had training, I guess very likely pa na gawin nila super lakas si Uub if trained.
I mean, Goku became more powerful than a God of Destruction in under an hour. haha So yeah, anything is possible.
