I dare say it won't take long to break out the heavy artillery... And when it does, well, let's just say it might level a whole city just from explosive power.
This'll be an interesting fight though, if one had to analyse it. Powergirl's definitely got the bigger muscles, youth and height over Supergirl, but one might argue Supergirl, being more experienced, would've already taken this into account and found other ways to beat PG. Oh, and she certainly doesn't hold back.
Good work here, and hope to see more like this one!
