The dragon killed Assistant Coach Caroll, a cleaner and the headteacher, Mr Armitage, to feed his mate. He later on killed Coach Dawson himself after dragging him through a rift, after he threatened to kill the dragon imprinted onto him. Ram Singh suggested that he make Dawson's skin into leather, to "make a chair or something". (TV: The Coach with the Dragon Tattoo)
The male Leaf Dragon was intelligent and could understand and speak human languages. He seemed to love his mate and was prepared to kill innocent people to feed her and therefore, save her life, though he appeared to hate doing it. He was eventually persuaded by Ram to take Dawson and his mate back to his homeworld rather than having to continue murdering innocent people just to keep her alive.
