And here comes the point in which I begin to cheat a little and include some characters outside of Arkham City.

Derpy Hooves as the short lived Batzarro, There are two major reasons for this choice.

The first is that, Derpy has always come across to me as something of a bizzaro Rainbow Dash, what with the similar design, her color palette, and silly mannerisms.

The second is that I'd write this character VERY differently than how dc wrote it. I'd make Batzarro the hero of a parallel, derped universe equivalent of Gothamville who's made her way to Dashy's universe. Hilarity ensues. I also have the idea of making her have a cute, niave innocent crush on Rarity/catmare...yay or nay?

Next up, Applejack as the Commissioner.
