Gottlieb maintains a recurring presence throughout the series and its special. He stands as one of Kaz Kaan's closest friends, alongside Lexy, with the trio frequently socializing at various Neo Yokio locations, from public events to casual gatherings.

Physically, Gottlieb possesses creme or sandy-toned skin and sports facial hair, typically a mustache and beard. He is recognized by his distinctive round red glasses and maintains an average build, trimmed eyebrows, and shaved hair, presenting a consistent appearance across all appearances.

His personality is quiet yet laid-back. He frequently joins Lexy during social outings and their shared business ventures. Together, they co-own the Caprese Bar. Their entrepreneurial efforts include product development and promotion, such as creating innovations like Canned Caprese. At promotional events, Gottlieb interacts with Kaz and encourages public engagement with their products.

Gottlieb appears in multiple episodes. In "O, the Helenists...", he and Lexy approach Kaz seeking endorsement for a new cocktail. During "Hamptons Water Magic", he accompanies Kaz and others to the Hamptons, where unstable water magic briefly transforms him into a panda. He later returns to normal without lasting consequences.

In the special "Pink Christmas", Gottlieb continues his established role. He appears with Lexy promoting their latest innovation, Canned Caprese, and interacts with Kaz during these activities, including having Kaz walk around Neo Yokio to help market the new product. His role remains primarily supportive within Kaz Kaan's social circle, consistently focused on his business partnership with Lexy and casual social interactions.
