OMG I don't know why I'm still talking to you. Your using Gladiator taking on Cannonball and Black Cloak as an example? Do you not know what PIS means? Gladiator would stomp them, but Wonder Woman and Barda are really strong, so it stands to reason that they can hurt each other.
You know that I can call WW vs BB PIS too, right? If we would go by that logic, You would have to use other Barda's feats to prove that this fight isn't PIS. And then I would be able to say that it is PIS again. I told You - You can't call everything PIS.
BTW, it is CIS in both situations. Both: Gladiator and Wonder Woman aren't using their full strenght and reflex in their fights, that is why You need to either:
-win with them
-had Your feats described by narrator (or something similar to this, like destruction of large object/area), like Hyperion had.
