One day while Fluttershy was walking in the wood, she found a poor injured alien dog. So she decided to help it. Little did she know that the thing she pulled out of its arm was a weapon that belonged to a Predapony.

I made this in Photoshop.

Fluttershy is from My Little Pony: Friendship is Magic.

Alien dog is from Aliens 3.

Predapony is based of Predator.
