Bebi is able to possess people and increase their powers by adding his own to them. He is also able to leave little eggs in people so he can control them even after leaving their body. He encounters the Saiya-jins, and possesses Trunks first, but was too weak to keep him. He later arrives on Earth, and manages to find the perfect body for him, Vegeta.

Goten: Episode 25; basically tangled with him until Goten went all out with a Kamehameha. That's when Bebi possessed him.

Piccolo: The reborn Namek that came to Earth to escape a disaster on his own planet. The Namek ascended to the position of Kami (God), but had to purge his evil first. This evil became Piccolo Daimaou. He terrorized the world but was eventually sealed by Mutaito. Released by Pilaf centuries later, Goku managed to kill him. However, Piccolo Daimaou spat out an offspring to continue his legacy. That became the Piccolo we know. In DBZ, he merged with Kami again, and that is the Piccolo that exists in GT. In GT, he first appears after sensing something wrong with Gohan (possessed by Bebi), but Bebi-Gohan blasted him. He later shows up as the Earth was about to explode, and apparently still has the wound Gohan gave him. He stays with the Earth to sacrifice himself so the Black Star Dragon Balls would perish with him (created by that original Namek).

Buu: A Majin (Demon) created by a sorcerer Bibidi millions of years ago. The Kaioushens fought him, but either died or got absorbed, which eventually turned him to a fat Buu. That Buu was eventually sealed, and left on Earth. In DBZ, Babidi, son of Bididi, found Buu and released him. He eventually killed Babidi, but Mr. Satan became friends with him. In the final battle, Buu split to two, a fat good one that was friends with Mr. Satan, and the original evil one. Eventually, Goku kills the evil one with a big Genki Dama (Spirit Bomb). Mr. Satan pleaded to the others to spare the fat one, and promises he won't get in trouble, so he lived with Buu as his friend. Mr. Satan also uses Buu in the tournaments. Get Buu to beat the others, then lose to Mr. Satan. In GT, he still lives with Mr. Satan. The only one immune to Bebi's possession, he eventually merges with Ubuu again (he's the evil Buu reincarnated as good guy). After that, he only appears again within Ubuu to tell him about Mr. Satan being the hero of the people.
