Batman hunts for one of his feared enemies so he could bring him to justice in Gotham City. However, he enters a place that unexpectedly transports him in an unknown world of which he has no clue what it is. While he struggles to complete his mission, an evil rises up in Equestria that would require not only his tactics, strength, and resources but also the assistance of the ponies. How will the Dark Knight react to them for who they are? Will they accept this dark being who is somewhat unlike them? Will they understand him? The more the Caped Crusader associates with them, the more he’ll realize that it will be like Gotham all over again.

Note: This happens after the events of Batman Begins and the season 3 premiere. This also takes place during season 3 of MLP: FIM.
