The highest diety remaining after Buu's slaughter of the other gods, Kaioshin comes to Earth during the Budoukai to warn Goku about Babidi's plan to revive Buu.

They have a spiritual link, so if one of the two dies, both of them die. As the guardian of Earth and creator of the Dragonballs on Earth, Kami plays a key role in the story.

Grower of the rejuvinating Senzu beans and guardian of the holy water, Karin lives in a tower that hangs just below Kami-sama's lookout. Being weak physically, Karin is quite wise and intelligent.

Keeping a close watch on his brother Freeza, Koola was sure that Goku would be defeated. After Freeza was killed, Koola heads to Earth to finish off the last of the "Saiyajin trash" in movie #5. Similiar to Freeza in abilities, Koola can change into a 5th form, one more than his brother.

Unable to fight in his badly damaged state, Koola used the giant metal planetoid to create metal clones of his original form. These replicas, known as Metal Koolas, can regenerate from a reserve of metal in their bodies. Flaws in the Metal Koolas are instantly corrected when they are found, making each robot a very formidable opponent.

A Buddhist monk, he shaves his head by choice (#18 convinces him to grow some hair later in the series). Kuririn is willing to sacrifice his life for Earth (and he has many times), and whenever possible he is at Goku's side.
