Originally posted by carver9Tbf, Merus was just a trainee Angel, so he's vastly inferior to the likes of Whis. He and MUI Goku were pretty much equal during the Moro arc.
It doesn't make sense that Beerus is still above Goku. Goku just defeated an Angel like character and Angels are usually >>> Destroyers.
But yeah, Beerus being as powerful as he is doesn't make any sense at all. I guess Toriyama meant it when he said(during BoG) that he didn't have any plans for Goku/Vegeta to surpass Beerus.
