About the FandomEdit
The exact origins of this EU are unknown, but all of the characters used in the crossover are Former Antagonists (or Protagonists that held the title of "Bad Guy") in the RotBTD fandom. Since all the characters did "bad" things and had changed their ways after they each met people that helped them understand that they're not really bad, fans decided to put them together in a crossover. Since it is not canon, ideas for this crossover are shown through fanart, videos, and fanfiction.
