Unfortunately, having burned more than they can feed on in the process coupled with their heightened metabolism, the dragons gradually resort to cannibalize one another. Scars that littered throughout his body suggested that he spent a lot of his life fighting alongside his kin in overthrowing humanity as the most dominant species on the planet. He and his brood established a nest over the ruined London, right near a cavernous system where he originally laid dormant. In 2020, the Bull Dragon has become the alpha of the entire dragon race (if not only his brood), having outlived other males and all females for himself. A boy named Quinn was the only one to survive the carnage and was left traumatized due to having his mother been killed by the dragon.

Angered by the intrusion, the Bull Dragon fought his way out to the surface and killed everybody else who were unfortunately enough to be in his path. Regardless, he was the first dragon who was awakened upon being disturbed by construction workers who inadvertently stumbled upon his dormant form on the London Underground many years later.

It's not explicitly stated whether the Bull was hatched during the end of the Mesozoic era or during the Ice Age, only that he's one of the most persistent male of his race unlike others who are either perished from conflicts against humans, died challenging him over the position as alpha male, or both.
