What would happen, if Marty was sent to Equestria when the lightning struck the flux capacitor, instead of sending him back to 1985?

What kind of random adventures await for the irish bug?
Will Pinkie Pie end up on earth?
Was that just a major spoiler for a future chapter?

Well, read this and find out!

Rated Teen for language in next chapters, no Marty X Pony action, he has a GF. You guys make me sick, JK lol.
Might add more characters in the future (he he future) The ones in character tags are the ones that will surely show up in the next chapters.
Feels a bit rushed I know. I am new to writing.
