Mr. Popo

Mr. Popo (ミスター・ポポ, Misutā Popo) is an assistant-deity who is apparently an immortal genie who tends the grounds of Kami's Lookout. He is bound there eternally as the gardener and caretaker but he can travel anywhere in the world when the occasion calls for it, using a magic carpet for Instant Transportation.
Though he does not appear to physically age, Mr. Popo is very old; having served Kami, the Guardian of Earth for hundreds of years, also serving Kami's predecessor, as well as guardians of the Earth into the distant past. Being the loyal and faithful servant that he is, his "job description" and usefulness covers a wide variety of areas, such as tending to Kami's palace and grounds, keeping the Lookout clean, training Earth people to deal with especially dangerous enemies of the planet (such as Piccolo Jr. at the end of Dragon Ball, and Vegeta and Nappa at the beginning of Dragon Ball Z), taking over the lookout when the guardian is away, odd and interesting things such as helping to reconstruct Shenron if needed, and most importantly, supporting, serving and taking care of the current Guardian. He also tends to the ancient butterfly garden that he planted thousands of years ago, and enjoys the more simple things in life.
He is one of several Dragon Ball characters, such as Android 8 and Android 16, who openly and greatly appreciates the natural world. Mr. Popo commonly refers to himself in the third person. While FUNimation's English dubbed Mr. Popo speaks complete with highly sophisticated sentences, the Japanese version portrays him as a seemingly primitive figure. His grasp of the common tongue is less than the English-dubbed version makes it out to be.
