This story takes place on an alternative universe of Equestria, inspired by DC Comics.

Babs Seed is this Equestria's version of Pre New 52 Power Girl. Hot headed and brash, she believes there's no problem she can't punch her way out of, even if those problems are her self doubts about her unpredictable powers and questionable relationship to Applejack, this Equestria's version of Superman.

Sweetie Belle, the Mare-Do-Well, wants to help Babs use her powers with skill rather than impulse.
Scootaroll, this Equestria's Billy Batson, wants to help Babs understand why her powers change so much.
Apple Bloom, this Equestria's Supergirl and real relative to Applejack, wants to help Babs by giving her space, and staying out of her way.

All of them will need Babs help when villains unite to take down her friends in the most perverted way possible. Powerfilly's attempt to measure up and be the hero everyone wants her to be might require more than just her fists, especially when the villains are ready and waiting for her.

All fictional characters are over 18.
