Give me one single evidence that yellow SSJ multiplies SSG power by 50x
This argument doesn’t exist. It never existed. You’re arguing with a ghost.
The actual argument is: Goku, as a mere SSJ, is superior to his power as a SSG (the Uni Clash). Then, later, he was verbatim stated to be stronger than that in Base against the Beerus Ball. This means his base power level is Uni+—
BoG Level. Not FORM. Level of power. Then, Goku can turn normal SSJ on top of this. Making that prior level of power 50x larger.
That is all.
Objective, empirical data.
Then, Cabba fights Base Vegeta, who is explicitly Goku’s equal, and is Vegeta’s equal. Thus, quite necessarily, he must be on that same level of power.
There is no other option. No other explanation than what the text quite explicitly lays out. The only one indulging in Headcanon in this thread is yourself. Not I, not Damage—Just you. You and solely you. And instead of respectfully bringing up the topic once in a while, simply even agreeing to disagree, even, or making your own thread, you sit in here and prattle on, incessantly, all day. All night. After people have asked you to stop. After people have requested you put your money where your mouth is. Answering the same questions over and over and over again.
It’s repetitive. It’s irritating. More importantly, it’s unwarranted. Please—For the love of all that is holy and blessed by the Seven Super Dragon Balls, be quiet. Go to bed. Or talk about something else. Literally anything else.
