Wekapipo is an exiled Neapolitan and a practitioner of the Spin. After serving as a royal guard for the Kingdom of Naples, he entered the service of Funny Valentine, later working against him to protect Lucy and Steven Steel.

Wekapipo is most notable for his bizarre haircut, which consists of a series of shaved grid lines and squares of short hair. He enters the story sporting a mustache, which he later shaves off. He is often shown wearing a light-colored jacket and pants covered with paired overlapping polka dots. He sports pants of the same design.

Wekapipo is a remarkably stern and serious individual, focusing on whatever goal he has and tolerating little the hijinks of Magent Magent. Wekapipo would do anything to protect his sister. During his youth, Wekapipo was entirely devoted to his sister. He had gone out of his way to force a divorce after learning that her husband beat her. The news of her supposed death made him seemingly depressed and he has since then had a bleak outlook on life.
