Alright, so, I've always wondered if Powergirl is to Supergirl what Superman Prime is to Superman. I know that Superman Prime is from Earth Prime, which is now what Earth Two used to be. Powergirl is from Earth 2. Both are supposed to be much more powerful than their Earth 1 counterparts. Just like how Supergirl and Superman are cousins, are Powergirl and Superman Prime cousins, or is Powergirl as powerful as him, or at least possessing the potential to become as powerful as him like Supergirl possesses with Superman? Are they cousins, too? If not, then could there be a Supergirl from Earth Prime, so a Supergirl Prime?
