The Cannibal was a wild dragon that lived on Dragonstone during the Dance of the Dragons. He was called Cannibal by the smallfolk of Dragonstone because he would practice cannibalism, feasting on dead or newborn dragons and dragon eggs. He was one of three completely wild dragons dwelling on Dragonstone, the others being Sheepstealer and Grey Ghost.
The Cannibal was black as coal. He was the largest and oldest of the wild dragons.
The Cannibal's exact age has not yet been stated. The wild dragon Sheepstealer is said to have hatched when the Old King was young - that is, early in the reign of Jaehaerys I. The Cannibal is stated to have been the eldest and largest of the three wild dragons, and was therefore even older than Sheepstealer.
The Cannibal was known to attack smaller dragons. He laired at the back of Dragonmont. Prior to the Dance of the Dragons a dozen would-be dragontamers had made attempts to ride him and his lair was littered with their bones.
Some among the smallfolk of Dragonstone claimed that the Cannibal lived on the island even before the Targaryens arrived in 114BC. If it was from a different lineage of Valyrian dragons altogether, that might have explained why it was so antagonistic to the other Targaryen dragons. However at least some maesters doubt these claims.
When Prince Jacaerys Velaryon called for dragonriders during the Dance of the Dragons none of the dragonseeds were fool enough to disturb the Cannibal due to his reputation - and any who were did not return to tell the tale.
When Silver Denys, a man who claimed to be a descendent of King Maegor I Targaryen, tried to master Sheepstealer the dragon tore off his arm. As his sons struggled to staunch his wound the Cannibal descended on them, drove off Sheepstealer and devoured Silver Denys and his sons.
When the carcass of the Grey Ghost was discovered at the the Dragonmont's base Ser Robert Quince was quick to name the Cannibal as the killer (in fact it was Sunfyre). The fisherfolk began to worry that the dragon would turn upon them and urged Ser Robert to have the Cannibal dispatched but he refused, reasoning that if they left the dragon alone he would not bother them.
The Cannibal survived the Dance of the Dragons, only to mysteriously vanish after the war.

If we do not trouble him, the Cannibal will not trouble us.
