This is an idea I had for one fanfic, although I do not know how to do it right (not to mention that my english is very poor); and you, what do you think? For the record, yes, of the characters My Little Pony, would be to focus more on Spike, and Spike would be to (somehow that I still haven't thought) ends up in Beach City.

MLP character changed to a human and teleported to Earth? That's pretty original. But you'll have to think of a good reason for Spike to be there and more importantly, why he is transformed.

3671671 Oh ok, when I saw the pic with the human and Spike in a half n' half, it looked like they were the same person.

That's not just a human, silly, it's Steven Universe!

Caio is suggesting a crossover.
