Prince Aerion Targaryen, better known as Aerion Brightflame or Aerion the Monstrous is the second son of Prince Maekar. Aerion is exceptionally cruel, and is loathed by his youngest brother Aegon, who was often the victim of Aerion's torments. Aerion once threw Aegon's pet cat down a well,he would visit him in the middle of the night and hold a knife to his privates, jesting that he would remove his privates and turn him into a sister for Aerion to marry. He suffered from the Targaryen madness.
