Being able to tell you the species, range, diet, and specific habits of any living beast on the face of Azeroth and Draenor, Kalhoun is the equivalent of what many people would call a “geek.” When not out on missions, much of his free time is occupied by teaching gigantic, dangerous creatures cute tricks. In fact, the uglier and more hostile the creature, the more Kalhoun is certain to be enthralled by it. 

Beyond his Hunteriffic pursuits, he is an accomplished Engineer, often employed to repair machines of war or other such gizmos (adding in his own “improvements” of course).

Though his social skills are awkward at best, Kalhoun carries himself with a very “CAN DO” attitude.
