Vhagar was a she-dragon of House Targaryen. She was ridden by Queen Visenya Targaryen during Aegon's Conquest, alongside Aegon the Conqueror's Balerion and their sister Rhaenys's Meraxes. Other known riders of Vhagar are Prince Baelon Targaryen, Lady Laena Velaryon and Prince Aemond Targaryen. She was named for one of the gods of Old Valyria. Vhagar was green with a bronze underbelly. According to Tyrion Lannister, she was large enough that one could ride a horse down her gullet. [Doesn't Speak]

Balerion's scales and wings were black. His fire was black, sometimes with swirls of red. When he was in the fullness of his power, his flames could melt steel and stone, and fuse sand into glass. Balerion was the largest of all the Targaryen dragons since Aegon's Conquest. [Doesn't Speak]

Dreamfyre was a slender she-dragon. Her coloration was primarily pale blue, with a silver underbelly. She had silver crests and pale blue wings. By 35 AC, Dreamfyre was large enough for the twelve-year-old Rhaena Targaryen to mount her. Dreamfyre was hatched during the reign of King Aegon I Targaryen. As a hatchling, she bonded with nine-year old Princess Rhaena Targaryen, Aegon I's first grandchild, in 32 AC. Three years later, she became Dreamfyre's rider. She is gentle but firm.Doesn't Speak]

Her typical attire consists of a sleeveless, backless top and short tight pants, with two lapels on the front and the back. She wears an obi around her waist, as well as purple arm-warmers which extend up to her shoulders.

The Cannibal was black as coal, with menacing green eyes. He was the largest and oldest of the three completely wild dragons dwelling on Dragonstone, the other two being Sheepstealer and Grey Ghost. The smallfolk of the island called him the Cannibal because he would practice cannibalism, feasting on dead dragons, newborn dragons, and dragon eggs. The Cannibal's exact age has not yet been stated. He's aggressive. [Doesn't Speak]

Dangerous, Aggressive, Wild And Cannibalistic

Syrax had yellow scales. She was huge and formidable, but not as fearsome or experienced in battle as Caraxes. She was kept in chains and exceedingly well fed. At the time of the civil war called the Dance of the Dragons, Syrax had not hunted for years. Rhaenyra first took Syrax as a mount in 104 AC, when the princess was seven years old. Syrax was described as a "young" dragon at the time, and Rhaenyra herself named her "Syrax" (after a Valyrian goddess). [Doesn't Speak]

Proud, Loyal, Strong And Honorable

Caraxes was red in color, and was huge and lean; a dragon in his prime. In battle he was formidable, fearsome, and experienced. During the Dance of the Dragons, Caraxes was about half the size of the huge and elderly Vhagar. Meanwhile, Vhagar was three times the size of younger dragons such as Tessarion or Seasmoke. Due to his larger size, Caraxes was not as fast as his smaller brethren, among whom was Meleys, a female dragon who was of similar color. [Doesn't Speak]
