Diablo is an efficient, forward-thinking individual who is also contemplative and quiet. He generally respects Lupe as a leader, though he is always willing to give his assessment of a situation. He's somewhat prone to arguing with Reynard due to their opposing viewpoints- his optimism clashing with Reynard's negativity- and was willing to teach the Overlander girls, Aerial and Athena, good manners even before their induction into the Pack. He possesses a wealth of wisdom and experience.
