last au i'm ever making. also, i trimmed down my au list and got rid of aus i didnt want to do anything with, like the nights underground and beneath the battlefield. so please don't ask me things like "lol how many aus do you have now??? xD" because the answer's 4.
Hearts of Horses is a crossover AU with My Little Pony: Friendship is Magic. It's an AU concept that I haven't seen done exactly well, but has a lot of potential for something cool. As always with crossover AU concepts by me, I try to go less for the "overdone" swaps, like Pinkie Pie being Sans. As you can tell from the drawing above, Discord is Sans and Fluttershy is Papyrus. (Discord's low budget Sans cosplay is part of a giant joke with him, before you comment.)
The rest of the swaps include:
Frisk - Sunset Shimmer
Flowey/Asriel - Cadence
Toriel - Starlight Glimmer
Napstablook - Trixie
Undyne - Rarity/Applejack
Monster Kid - The CMC
Alphys - Pinkie Pie
Mettaton - Twilight/Spike
Muffet - Rainbow Dash
Asgore - Celestia/Luna/Shining Armor
I will not make a comic for this AU at the moment, but later on down the line when Unex and The Underground Turnabout are farther on in their stories, maybe I will make one. The concept is too interesting to not ever do anything with it!
Oh. I've been rambling. Uh, enjoy the picture. And hopefully the AU concept.
