#If there would even be an in-universe reasoning for it; U6 still has Sadala in good standing and they're not conquerors so what reason woul

[fandom-trash-xl]

Just putting the hypothetical out there, but I think, out of the U6 Saiyan pack, the one that'd be the best fit to go Majin would be Cabba

We know that Caulifla is the one with the hot head who'd have the power cravings, but Cabba having this opportunity presents more of shock, having the most rational and well-composed suddenly snap like a twig from the emotional burden he carries on his back. Plus, after all, Cabba is intended as Vegeta's Universe 6 parallel in a sense, just as Caulifla is to Goku and Kale is to Broly/Gohan.

The manipulation that forces him to succumb? Being convinced that this power will be key to achieving justice. Of course there's the consequence of absolute power corrupting absolutely.

In this hypothetical, when Frost comes to trial for the truth he reveals during the Tournament, the truth is somehow retwisted in his favor, Cabba is prevented from stepping forth as the key witness to his confession, and the lizard manages to get away scot-free. Cabba feels absolutely betrayed, infuriated that his voice has no power against the lizard who manipulated him for so long. He wants to be heard, be taken seriously.... so he is given a chance to put justice into his own hands, to take down Frost himself. The corruption of power ultimately twists Cabba into a sort of Light Yagami type.

But you may ask, where would the Majin powerup come from? Who's the equivalent Babidi to pull strings in this universe? Well, he's been lying in plain sight as the supposed weak link of the Tournament of Power...

...Dr. Rota.

Cabba ends up crossing paths with the witch doctor, a peddler of spell cards and talismans. When the Saiyan vents out his tale, it intrigues the boar, telling him to follow him to the back. Rota believes he has quite the special spell for such a case as Cabba's.
