Vermithor, known as the Bronze Fury, was a dragon, apparently male, that was ridden by the Seven Crowned King Jaehaerys I Targaryen.
Its scales and wings were bronze and beige.
According to legend, in the year 34, Princess Rhaena Targaryen placed a dragon's egg in the cradle of her newborn brother, Jaehaerys. From this egg, Vermithor is said to have emerged and immediately bonded with the child.
In the year 42, Jaehaerys' father, King Aenys I Targaryen died in Peyredragon during the War of the Faith. During his funeral, Vermithor helps Silverwing and Vif-Argent to set fire to his pyre. Soon after, Jaehaerys' uncle Maegor I Targaryen usurped the crown.
In 44, Jaehaerys, his mother, his sister and their dragons escape Maegor's surveillance and find refuge in Accalmie with Rogar Baratheon.
In the year 48, Vermithor is big enough to be ridden by Jaehaerys. Jaehaerys declared his claim to the Iron Throne against his uncle Maegor that same year.
Jaehaerys' main supporter, Lord Rogar Baratheon, seems to plan to use Vermithor and Silverwing, ridden by Jaehaerys' sister, Alysanne Targaryen.
They are joined by Rhaena Targaryen, riding her dragon, Firebird. Together, the three dragons are spotted above King's Landing nine days after the mysterious death of Maegor I Targaryen.

At the wedding of Alyssa Velaryon and Rogar Baratheon, Vermithor and Silverwing make a great impression on the people of King's Landing.
That same year, Jaehaerys fled on Vermithor's back to Peyredragon, so that he could secretly marry his sister Alysanne. In the year 50, Jaehaerys came of age and returned to King's Landing. He flew over the city three times before landing, and the people cheered him. Thereafter, Vermithor is used as King Jaehaerys' mount for each of his royal travels.
Vermithor was ridden by Jaehaerys I until his death in the year 103. Without a rider, he becomes wild and sets up his lair in a smoky cave in Montdragon.
