First off, I'm not a good writer by any mean but I think I have a good idea because I haven't seen a lot of good gundam fan fic's so . sorry for any spoilers for Gundam: iron blooded orphans

after his death from the final battle with Julieta and Gjallarhorn, he and his Gundam, Barbatos, suddenly wake up deep in the Everfree, but he wasn't the only one who arrived. His past enemies like lieutenant crank, ritter carta, and graze ein, all of who teamed up with queen chrysalis in order to return to their world, plan to try and take over Equestria. Faced with this, Mika has decided to help the mane six and beat queen chrysalis and save Equestria.

I been wanting to write a story like this for a bit but I don't know what to do with it.
