Vhagar is a dragon from the fictional universe of A Song of Ice and Fire, created by George R.R. Martin. She is one of the largest and oldest dragons, originally bonded with Visenya Targaryen, one of the three Targaryen siblings who conquered Westeros. Vhagar is known for her immense size, strength, and fierce temperament.
Throughout the history of the Targaryens, Vhagar has been ridden by several notable figures, including Aemond Targaryen. She plays a significant role in the Targaryen civil war known as the Dance of the Dragons, where dragons battled for control of the Iron Throne.
