The weirdest thing is how he thought of it. No Oc at my school is anywhere near that. In fact, we're all pegasaii and unicorns.
Did he watch enough of the show to know of alicorns and dragons being powerful? Or is this all his imagination on hooves? He may just want to be like every one else; combining Pegasus and Unicorn into an alicorn, but know he will never truly fit in. Those feelings of alienation making the dragon aspects. Inside, he wishes he had the powers he gave to his 'pony.'
