Black Flier was originally a pegasus whose job it was to regulate the weather in Equestria. Sometime later, he became an Alicorn through unknown "illegal" means. Due to this, he was banished into the plains of Equestria and to remain a hermit for the rest of his life. He now reacts to MLP: FiM videos whenever he feels like it, which is usually when he is bored.
