Prince Aegon Targaryen is the eldest son of Viserys I Targaryen and his second wife, Alicent Hightower. Despite being his eldest son, his Viserys refused to name Aegon his heir. Instead, he named his eldest daughter, Rhaenyra Targaryen, the Princess of Dragonstone and future queen. As such, Aegon holds a deep hatred for his sister for stealing what he calls his birthright. He is married to his sister, Helaena Targaryen, and the two of them have three children together. He frequently mocks his elder sister and claims that her many children are bastards in the hopes of destabilizing her claim to the throne. Aegon is a dragonrider to the dragon Sunfyre.
