I'm currently trying to tell the story of the Power Ponies, as the character Bellcord (Discord counterpart) tries to redeem himself by being Captain Good-Guy after being released from prison. The Power Ponies don't trust him, and Bellcord tries to force them to believe he changed. They all have a rivalry, until the eight if them get framed by a new tall super villain dark horse named Mordum, who has the power of dark magic, and wishes to conquer all of Maretopolis. I have my other characters ready, so if anyone could help me start the story or add anything good to make this more exciting, I'll be grateful.
