After her parents were murdered right before her eyes, Diamond Tiara swore to get rid of crime in Ponyville. She became the vigilante of the night, Batmare. Can she handle being a bachelorette, head of Rich's Barnyard Bargains, and being Batmare without someone finding out who she is?

The reason for the Alternate Universe category is that there is no magic in this Equestria. Batmare will face villains that would normally be OP against her, so I took away magic to level the playing field so to speak.
