The thought if Richard and an evil pony is just adorable :)

... who is the crossover?

Hahaha omg thats awesome, U just combined to godly things in too an epic win. If this was youtube I would totally give thumbs up.

The Thoroughbred of Sin and the Mistress of Magma, huh? *cracks up* Love the story!

:D Awesome. Simply awesome. I didn't see it coming at all. This rocks.

My face met my palm when you mentioned the "taking over some other world". In a good way. Awesome crossover.
