In the anime Demashitaa! Powerpuff Girls Z, Arturo, also known as Little Arturo, is a member of the Gangreen Gang, a group of green-skinned teenage delinquents who serve as minor antagonists. He is adapted from a character of the same name from the original American series, The Powerpuff Girls.

Arturo is depicted as the smallest and youngest-looking member of his gang, giving him a childlike appearance that contrasts with his mischievous behavior. His personality is characterized by impatience and a somewhat immature demeanor, which often makes him prone to quick, impulsive actions rather than careful planning. Despite his youthful look, he is an energetic troublemaker who participates in the gang's petty crimes, which include prank calls, graffiti, and general vandalism.

His role in the story is that of a recurring nuisance for the Powerpuff Girls Z. As part of the Gangreen Gang, he is considered one of the weaker villains the heroines face. The group originally consists of ordinary humans who gain their green skin and abilities after being exposed to Chemical Z. Arturo’s fighting style emphasizes speed, allowing him to move and attack quickly in confrontations.

Visually, Arturo’s design in this version differs from his original counterpart. He sports a gourd-shaped hairstyle and typically wears shorts with a sleeveless shirt, reflecting the updated artistic direction of the Japanese anime.

A notable aspect of Arturo’s background is his family life. He comes from an extremely large household and is identified as the third child. In a running joke that highlights his lack of attention at home, his parents frequently forget his existence, sometimes mistaking him for the fifth child instead of the third. This neglect plays into his motivations, as he often seeks attention and validation through his actions with the Gangreen Gang, contrasting with his otherwise overlooked status in his own family.
