Like Brennan, his inability to pick up on Booth, Hodgins, and Montenegro's pop-culture jokes and references is a running gag and a source of humorously awkward moments in the lab, though he has shown he has other "normal" interests such as being a basketball fan and a trained singer. A recurring element in the show involves Addy and Hodgins amicably but resolutely competing to be "King of the Lab". In "The Pain in the Heart", a trophy, presented to him by Saroyan recognizing Zack as "King of the Lab", is revealed. Zack is removed from his position on Brennan's team in the season three finale, "The Pain in the Heart", when he is revealed to be the apprentice of the serial killer Gormogon.

He is best friends with former coworker Zack Addy and often tries to "educate" him on social norms. They often compete for the title of "King of the Lab", referring to whoever has more useful information in the investigation at hand. His family owns the fictional Cantilever Group, and he is extremely wealthy and is a major sponsor of the
