Billy the Homicidal Radioactive Goat from Space!!!

A radioactive and homicidal goat from space crash lands in Equestria. The Equestria is in for one hell of a trip... if they survive

A new threat has landed in Equestria, and it may be the greatest yet. Fueled with radioactive strength and homicidal thoughts, this goat is not one to be trifled with. However, Luna is convinced he can be saved and reformed.

Too bad Discord is the only one on Luna's side.
