Regardless of time shenanigans and the alpha time line, do you think that 12 got tier trolls could win against bec-Noir?

Vriska ALONE could win against Bec Noir, of course all 12 together could.

That being said, Jack’s issue is that he’s looking for a challenge, to test his power and really have fun with a big fight- So maybe he wasn’t going against Vriska with ALL he had, he was making it more of a ‘fair’ Duel so to say. Technically he could just sorta backstab-kill every single of the 12 Trolls but, God-Tier, it’d likely not count as Heroic, just like with John.
