This is a crossover between My Little Pony: Friendship Is Magic & Dragon Ball Z. After seeing his Dad die (not literally) and the guilt of not finishing the fight between him and cell, so his father would still be here. Gohan ends up in Equestria, this will change Equestria and the ponies for ever, either in a good way or a bad way.

MLP: This starts in season 2, round about half way through.

The title is a reference to the film "A Monster In Paris".
