(Contains spoilers of MEGAMAN ZERO, MEGAMAN X.)
After nearly being killed by Dr. Wily. Zero learns a few simple truths about himself that put his entire life into perspective. As his rage fades, he finds himself exhausted from the constant war he has had to wage to survive. After surviving the explosion of ragnarock and the landing on is home world. He seeks a different form of releif. With the help of Cyber elves X, Elplizo and the four guardians, Zero finally finds a world with no technology. A land called Equestria

(First few chapters detail Zero's arrival on Equestria. The story will center around him, and will feature random members of the pony society. as a result I'm gonna leave the Cast list fairly blank for the moment.)
TITLE PICTURE badly put together by me. (LOLZ)

Oh yes, Megaman, Megaman Zero, and all other Megaman related References are thanks to Capcom for making the utterly awesome game.
[thanks to the 'how to write cross overs post thing that reminded me about that, I apologize for how long it took me to credit those I owe much to.]
