Moxxie is a vocal and realistic imp who often finds himself feeling insecure. Easily annoyed and prone to clumsy mishaps, he's quick to voice his frustrations, especially when things don't go according to plan. Moxxie is also queasy, making him uncomfortable in tense or gruesome situations. Despite his irritability, he has a comical side, with his exaggerated expressions and frequent blunders adding a humorous touch to his character.

His most notable feature, however, is his massive, fat butt—an enormous, round rear that dominates his lower body and often causes him physical awkwardness. Whether he's trying to navigate through tight spaces or sit down without toppling over, his huge behind adds both to his insecurity and the comedic moments he finds himself in. Though Moxxie tries to maintain a serious demeanor, his exaggerated proportions and clumsiness often make him the center of unintended humor.
