(Only posting this here because I just drew it, I'm not exactly coming back here anymore after a virus attack from this site.)
Anyway, this thought just came across my mind as "Hmm, Chaos from the Sonic universe is their god of chaos...Discord from the MLP universe is their god of chaos...I SMELL A TEAM UUUUP~!" And that's it. I drew it.
Personally, this whole piece is completely new to me. Its new because its the first MLP fanart I've done. Its new because its the first time I've drawn Discord. And its new because its the first time I've drawn Chaos. But I think it looks alright.
