How strong do you think Gori was?
He has to be physically at least a little stronger than Berser, right? At least it seems that way from their epithets, since Berser's is all about his wisdom but Gori's is all about his physical strength. If he is stronger than Berser, he should at least be able to survive a casual "shut up" slap from Ginbak like when Ginbak hammered Berser into the ground while talking to Jachi.
Might he even be as strong as or a little stronger than a Madaran? Ginbak did say that "this one" (Uki) couldn't have been the one who killed his son.
