So, here's the basic plotline:

Spike is a young mech pilot who defends the human race from giant monsters, but he doesn't do it alone. Aiding him are a group of girls who can turn into giant monsters themselves. now they could transform into anything; anthro ponies, Ultramen-like beings, or even magical girls who just grows giant. You could even mix it up if you like.

The setting could a post-apocalyptic or it could not, it's your call. There could be a meteor that created these monsters, they could be the result of nuclear tests, or they came from a portal like Pacific Rim.

Main parings: Mane Six, Sunset Shimmer, Starlight Glimmer, Ember, Gabby. Optional ones could be Fleur de Lis, Smolder, the CMC, Celestia, Luna, and maybe even some OCs and crossover characters.

Sounds like it will be a good read.
