That was awesome. I loved the crazyness of it all, especially the villain and her weapons and doomsday devices (the hairspray ray of doom
) and of course Flutterhulk.
Also, Rarity got an opportunity to shine with all that stuff she created while still being very much her. "I do so love functional accessories" indeed.
Oh, and I don't think enchanted comics are too much of a stretch in the ponyverse. It figures that someone would use magic for (not so harmless) pranks. We don't know how serious the situation really would have been had the ponies failed to stop the Mane-iac. I imagined it to be more like a videogame.
