well it all depends which Power Girl and which Hercules were talking about here, so pick High Scholar:
WHICH POWER GIRL VERSION:
Soon-to-be Power Girl w/ full control of her kryptonian powers? (strongest version, (she hasnt actually gained control of her powers yet, but this version is referring to when she will)
current Power Girl w/o control over her kryptonian powers?
classic Power Girl? (weakest version)
WHICH HERCULES VERSION:
Classic immortal demi-god Hercules? (strongest version)
Current mortal demi-god Hercules?
90's Mortal Hercules? (weakest)
Yes i know all about Power girls "distrtactions" i've even posted a pic of them in the hot super chick thread infact it was that pic which you posted the first one.
anyway hercules would be able to win but would'nt go for it and try his pick up lines on her. Power girl wo't be having any of it and beat his ass, then hercules seeing this fight her seriously but won't give up in trying to get laid by power girl he'll even put her in wreslting positions and say stuff which refers to sexual positions.
