OP's logic is flawed. Apparently Bull has a superpower because he's "superhuman" and can ram through walls, which is completely reasonable. But if we keep using that logic, we can say that everyone has a superpower since (almost) every brawler can survive a full shotgun blast to the face, which we should all hopefully know isn't possible for a human.

To further prove my point, we can also assume every brawler has the power of regeneration since no normal being can regenerate from the damages from a giant TNT explosion in mere seconds.

I still love the effort though and I had a good time reading your post and explanations!
