Memetic eldritch horror
You live in a post-apocalyptic wasteland. In such a world politics is just a matter of who has the most firepower
I’ve chosen to call this new species “chimera” for what I feel are suitably obvious reasons. The creature is a result of a wild magical burst from a rather exceptionally gifted filly named Quanta. In a flash of uncontrolled magical power, Quanta managed to fuse several creatures within her vicinity into a single being – a fully functional and completely new life form.
You put a mare in charge, you get nukes
You put a stallion in charge, you get chryssalids (I’m serious, read the fic)
There’s no situation where ponies come out on top
