Uub (ウーブ Ūbu) is an Earthling, and due to being the positive reincarnation of the completely evil Kid Buu, his name is a result of reversing "Buu". Uub's seiyū is provided by Megumi Urawa (Kid Uub) and Atsushi Kisaichi (Teen Uub) in the Japanese versions of Dragon Ball Z and Dragon Ball GT, respectively. In the FUNimation dubs of both series, he is voiced by Sean Teague.
