Lizard, a Pogona lizard, works as an office employee in a capitalist society alongside his anthropomorphic colleagues Lion and Toucan. He maintains a jaded and cynical demeanor, often acting as the relatively grounded presence within the chaotic workplace. Professionally competent and diligent, he contrasts with Toucan's laziness and Lion's naivety. He references a stable home life and a wife, indicating personal history beyond the office.

A defining physical trait is his detachable tail, which frequently severs due to workplace accidents or Toucan's antics. This results in exaggerated blood spurting, treated as a recurring comedic element. The tail regeneration is portrayed as a normal, albeit inconvenient, biological process for him.

His backstory includes a high school acquaintance who later became the obnoxious "Apple Bunny" mascot. Lizard once reached out to this individual during their school years when he was extremely shy, demonstrating a past inclination toward social connection despite his present cynicism.

Interpersonally, Lizard endures a relationship with Toucan characterized by enduring the bird's selfishness and laziness, responding with deadpan sarcasm or physical aggression. Despite this friction, he remains part of the core trio alongside Lion and Toucan, participating in their shared activities and misadventures.

Lizard occasionally displays pragmatism or opportunism, such as joining Lion and Toucan in visiting mascot acquaintances on the company's expense account. While maintaining his characteristic dryness, he sometimes participates in the surrounding absurdity. His background, relationships, and workplace role remain consistent across the manga and anime adaptations.
