lightyears away there is a race of Mare shaped Aliens, or Marelians to be more accurate, that need a special type of Matter to make themselves immortal though cloning. however there supply is running low and they need to find a new supply. though some freak chance they find it, on the planet Equus (which it the world Equestria is located on) but just to what lengths will these invaders go to for this element, and what will become of our Six Hero's?

this is kind of a MLP/Destroy all Human's story but with less brain stuff and more butt stuff…not that kind of butt stuff you sickos
