Damn, I didn't think much of it when I first read it, but this chapter of DBS might have dropped a serious bombshell. In the anime, Whis says one of the gods of destruction beat Beerus in an arm wrestling match, and that there was a mortal in their universe stronger than them... We've assumed that this was Belmod and the strongest mortal was Jiren, but... In this chapter it was confirmed that the god that beat Beerus in an arm wrestling match was actually Quitela.
Could Jiren actually just be a red herring? Is the mortal that's > Beerus actually one of the hidden figures from Universe 4?
