Burgess Olsen works alongside Belm Eyesburg in Doraco Chemical's Public Relations department, managing daily office operations and discussing workplace matters with professional camaraderie. He identifies himself as Belm's neighbor, work partner, and self-proclaimed "best friend." Burgess is married to Dana Olsen and participates in routine neighborhood interactions, including morning greetings with Belm and his family during shared commutes, where he expresses concern for Belm's well-being.

His dialogue includes lighthearted exchanges about office dynamics, such as comments on superiors' moods and company policies. When detective Sonia Summers confronts Belm, Burgess intervenes defensively—positioning himself physically between them, asserting Belm's identity against Sonia's claims, and expressing skepticism about her investigation into Doraco Chemical while attempting to redirect Belm away. He exchanges casual compliments about appearance with Belm's wife, Emma, and makes dismissive remarks about adolescent behavior regarding Belm's daughter, reflecting conventional social attitudes.

Burgess resides in the same community as Belm and Dana, sharing breakfast interactions and commuting routines. He shows no awareness of Belm's non-human nature or supernatural occurrences surrounding Doraco Chemical. His character maintains a consistent role throughout depicted events without significant development in relationships or perspective. No background details, personal history, or narrative significance beyond immediate interactions with Belm and colleagues are provided. Information regarding his portrayal in other media is unavailable.
