Discord is a magical and very powerful Draconequus (part-dragon/part-pony) who embodies the spirit of chaos and confusion. He stirs up disharmony everywhere he goes, but Princess Celestia believes his powers can be used for good and asks Fluttershy to reform him. Eventually, Discord grows a soft spot for Fluttershy and her friends, and begins to learn about friendship for himself.
