Boyle was once a menacing villain that almost succeeded in ruling over the world. He was defeated by heroes and after that he retired in Wyrmwood.
Boyle is very prideful and sometimes comes off as a bit vain, as he also often looks down on others. Even though he claims to be villainous and evil, he, in truth, has a good heart and cares not only for his pet Fang, but for others too. It was noted in the game that he has bragging sessions, and that sessions like these were one of the reasons for his downfall.
He is also quite sarcastic and it is not beyond him to lie or trick others, as he is after all a retired villain. He seems to like things that are sinister (like, for example, gargoyles) and he seems to have deep hatred and fear of paladins. Boyle is often seen friendly with animals and has a tendency of turning them into his minions.
Boyle has the look of a classic villain. He believes that spikes on his shoulders make him scarier.
