Shu, is Emperor Pilaf's ninja lackey and an anthropomorphic fox. He and Mai usually work together to carry out the work of their vertically-challenged and short tempered Emperor. He's one of the first villains in the Dragon Ball series, but perhaps villain is too strong a word. Like anything involving Emperor Pilaf, he's almost comic relief. He was originally known as Soba in the manga, but was renamed due to match the anime name given after Akira Toriyama forgot he had named him previously. He usually has Mai as a foil to his comic personality, where Mai is always in a serious attitude and usually armed with Conventional Weaponry.
- In the Ocean dub he is referred to as Shao, while in the FUNimation dub, he is referred to as Shu.
- He is played by Chris Cason in the Funimation English Version of Dragon Ball. However, Justin Cook played him in Mystical Adventure
- The combination of Shu and Mai's names form a food pun when put together to make the word "shumai" (a japanese dumpling), whereas the name Soba in the manga and Mai's name creates another food pun of "Soba-mai", a grain similar to rice (most likely coincide with their leader's name stemming from "Rice Pilaf").
- The Dragon Ball Collectible Card Game incorrectly lists Shu as Human.
