I take the position of neither. I do not think he was ever involved with Celestia romantically nor do I think he was Star Swirl the Bearded. He was just a being with huge reality-warping power who pretty much decided to do whatever he wanted just for fun...with a very twisted idea of what fun is and lacking the empathy needed to ensure his fun was not done at the expense of others.
For the sake of getting more people involved in this thread, I'm going to state my theory on how Discord and Celestia could have been a couple. I believe Discord was originally an outcast that fell for Celestia. When he did get the courage to approach her, she accepted him and they started dating in secret. Unfortunately, Luna was not a fan of Discord and convinced Celestia Discord was only after the throne. Celestia dumped Discord, calling him a monster. And so, he became one. After that, it was pretty much like in the show.
I've concocted this theory from a fanfic I read and the question of why Celestia wanted to reform Discord.
The Fun Has Been Doubled! is a My Little Pony: Friendship is Magic moderate-to-advanced forum roleplay. Set after the events of the fifth season, we currently have no overarching plot. Instead, we simply have created the world of Equestria for you as a giant playground to have fun in and to explore the magic of friendship. Canon characters and original characters are available for you to play as, both ponies and non-pony species alike! Just remember that we are account-per-character and we'll be fine!
So why don't you stay for a while, look around, and let us know if we should get a welcome party started for you.
