Earth Rainbow

once there was a pony. his name was Earth Rainbow. he was a normal pony, just like any other. but one event changed his life forever...

He was walking down the street with his blue coat, rainbow tail, and blue and green hair, when he thought "what if there are other dimensions out there. and if there are, then how would i ge-" his thought chain was cut off as a wormhole opened next to him and sucked him away into a parrelel world. while he was falling between the dimensions, he gained knowledge  about all the dimensions, how to get to them, what they actually are and which one he came from. he also gained the knowledge and thought processes of me, the author. he knew then what he must do. he must go and protect the dimensions from harm! and things that would see their downfall. he gained a tier 4 power to help him!
