With the professor busy with lab work, the main six, Spike, the powerpuff girls, and the rowdyruffs throw their own private bash.

"IT'S GAY L.A. METAL!" -John, 2012

Cutie mark crusaders, at the age of 8, begin to develop skills beyond the reach of any pony. Their strength increases dramatically, their hearing is now sharper than ever, and it seems they can no longer be damaged. This leads them to discover a secret that their families have hidden from them, they are not ordinary fillies, in fact, they were not even born as such. The very essence of the Tree of Harmony and the mysterious Chemical X runs in their veins, and it is up to them to decide what to do with these revelations.

Four powerful chaotic beings that revel in destruction and domination have made an alternate reality where no one can escape from and won’t rest until everyone around them is under their control. However could there be a flaw to this plan when one of their own isn’t as destructive as they thought? A My Little Pony: Friendship is Magic, Gravity Falls, Samurai Jack, and Powerpuff Girls crossover.

One day, Celestia and Luna, two scientists living in Ponyville, were exploring a mysterious castle where they found a strange jewel. When they took the jewel back to their laboratory to run tests on it, 15 lights shot out of it. Then three of the lights cause supernatural events and gave three normal girls superpowers.

This is not power ponies, but this is based off Powerpuff Girl Z but you don't need to watch it.
