Nah, Frieza is too untrustworthy and hates Goku too much.
He's the type of nikka to let Universe 7 get destroyed as long as Goku dies with it. Beerus won't make a difference...he blew up the Earth with Beerus on it with no fukks given just to get Goku. I could see somebody like Cell agreeing to team up with Goku, but not Frieza.
I feel you. Still a better story than watching Roshi and Krillin benefit from nonsensical power-ups. Every breh in this thread knows they're coming too.
Plus we KNOW Frieza respects Beerus as his OG. Begged him to promise he wouldn't interfere before trying to give Goku and Vegeta the beats. If he did try to pull some snake shyt, watching Beerus erase his ass again would be .
fukk it. I'll take Frieza AND Cell over Roshi and Krillin.
