Aemond Targaryen is the leader of the Greens in House of the Dragon, and now rules as Prince Regent and Protector of the Realm. He is Alicent Hightower's second son and third child overall and sits the Iron Throne after incapacitating Aegon with Vhagar's fire at Rook's Rest. He is the worst of the Greens at King's Landing and the one who went to the extent of killing his brother to get the throne.
