Shu

Shu appears alongside Emperor Pilaf and Mai in the very first saga of Dragon Ball and has remained a consistent part of the Pilaf Gang ever since. His skills as a ninja are occasionally useful for reconnaissance and infiltration, but he is far too weak to pose any threat in direct combat. Like the rest of the Pilaf Gang, Shu is accidentally wished into a child during the events leading into Dragon Ball Super, and he spends the Super era as a small puppy-like child tagging along with the de-aged Pilaf and Mai.

Shu's function in the story is almost entirely comedic. He serves as a yes-man to Pilaf, a slapstick target, and occasionally a voice of unintentional reason. His interactions with Pilaf and Mai form a reliable comic trio that provides levity during otherwise tense story arcs. While he has no significant individual moments or character development, Shu's consistent presence across Dragon Ball, Z, Super, and GT makes him one of the franchise's most enduring background characters, always present, always loyal, and always slightly confused about whatever Pilaf is planning.
