DESCRIPTION
Samus and Powergirl both love showing off for the 4th of July! Mercy just happens to be chilling where they are posing at but she doesn't mind watching them have fun (Mercy is a Giantess too she doesn't wanna ruin Samus and Powergirls fun!)
Edit: Forgot to add the Samus dressed up as Powergirl image! Now there twinning!
