Mao Mao is a furry cat with narrow green eyes and black fur, with two whiskers sticking out from the side of his head. He wears a red cape along with a red sash on his waist, crimson gloves, and leg protectors. Mao Mao has his own views on what makes a hero, to which he acts out and usually puts the town in danger. In "Mao Mao's Bike Adventure", he underestimates the Sky Pirates, to which he insists that a hero is never wrong. In "Sick Mao", he tries to continue his duty as a sheriff despite suffering from a severe cold, saying that being sick makes you weak, and heroes are never weak, which ends up afflicting his friends. Mao Mao appears to be averse to physical affection, only dishing it out himself on rare occasions, but seems to begrudgingly accept it from others (mainly Badgerclops). Mao Mao suffered childhood neglect from his father Shin Mao and possibly his sisters, which has caused an incessant need for him to be a "legendary hero" like they are. Mao Mao constantly tries to find ways to rise to their ranks and gain his family's respect. Mao Mao tends to exaggerate and be overly dramatic when he reminisces upon his adventures, or legendary related things. These can vary from slight alterations to completely distorting the truth of what actually happened, specifically if it is something related to his feelings like in "Bao Bao's Revenge". Mao Mao tends become frustrated easily. When things do not go as planned, he shouts in a booming voice, usually out of bottled frustration and anger.
