With the yaks, griffons, zebras, and everything in between out of the way, the only problem is the remaining hybrids. They can't exactly return to somewhere they never lived, but there's no way Hightower is letting them run free and corrupt the country again… well, there's more than one way to skin a cat. All he has to do is recruit strong, intimidating ponies to keep them in line, and before he knows it, they'll fizzle out and Equestria will be back to normal. Surely nobody would dare to get in his way, right?
