@AbillioncatsNot for Gren unfortunately, as the "Iron Hulk" he's suppose to be the bad guy in the ring. His three gimmicks essentially boil down to "Humans suck" in three different flavors:
As a Faunas, humans are weak.
As a Cyborg, humans are soft.
As a Giant, humans are puny.
He also does do some scummy things using his cybernetics, like the Arc Reactor (It's just a flashlight) in his chest is used to blind his opponents, and wears a polymer armor in the ring to help absorb blows. Not that he actually needs it (Cause the armor is plastic and Gren is beefy even without armor), but it shows that he's too cowardly to actually fight bare chested. He also has a tendency to have his "minions" gang up on his opponents, though this can turn against him when his opponent easily wipes the floor with the minions and leaves the Iron Hulk without any backup. That's not to say he can't hold his own, but unlike actual Gren who uses some level of cunningly applied brutality, Iron Hulk is all brute. While he's one of the toughest grapplers, he "lacks" the skill to use fancier or more complex holds, pins, and throws, and sticks to just throwing his weight around and slamming his fist, legs, or opponent around.
Essentially the Iron Hulk is the big bad that smaller, smarter, more agile faces have to outmanuver and outsmart instead of try to overpower.
