Do Bleach and Danny PhantomcCrossover, but let Danny gain new powers and his suit stays the same. But let him gain the powers to beat a lot of people and give him the power of Dan Phantom to beat Ulquiorra!

I like 21

I'll take challenge number 7 off your hands

here is an idea
danny phantom x deadpool x my little pony crossover
you come up with an idea but it must contain deadpool x pinkie pie

I'm interested in Challenge 1. That would essentially be an OC right?

Wouldn't mind doing challenge 7 and challenge 15 someday. Love the idea of Sam becoming a heroine.
