Damien is described as "intense", and willing to "bring Hell upon those who dare bother him." He enjoys destruction, as one of his hobbies is setting ants, and many other things, on fire. His resistance to fire is convenient, in this sense. His overly aggressive attitude intimidates many students, resulting in him being greatly feared throughout the school. This also acknowledged by teachers, as Ms. Panthera states he has anger issues, as well as "thirst for violence".

He dislikes it when people tell him to calm down, and is also opposed to the status quo. His main insult against the player is calling them a "noob", but he uses a variety of curses as well.
