» Namekians - This race is first introduced to us when Goku fights Piccolo Daimao, who is a very old Nameksei-Jin. But it isn't until the Saiyan Saga that Piccolo and Kami learn of their otherworldly origins. After Piccolo's death at Nappa's hands. Gohan,
Krillin and Bulma depart to the Planet Namek, to gather the original Dragonballs to revive their friends. During this time all the Nameksei-Jin are wiped out by Frieza and his men. They are eventually revived with the Earth's Dragonballs and sent to live on New Namek. All Nameksei-Jin are asexual as Toriyama based them on snails and slugs.

» Ogres - Also known as Oni, this race we see mostly as workers in the afterlife. Ogres either have a single horn or two horns on their head, some also only had 1 eye. They are given tasks like watching over Hell, checking the souls to make sure they have been purified, and other things. The Ogres gave their energy to Goku during the Buu Saga for his big Spirit Bomb. During DBZ Movie 12, they are almost all wiped out by Janemba. They run a sort of 'airport' to transport souls around heaven.

» Rito-Jins - Very human-like in appearance, this species had all of their families of these orphans killed right in front of their eyes by Frieza.
After their families were murdered by Frieza, these orphan's took up traveling the galaxy and capturing vessels. When they captured the Namek ship that Krillin, Bulma, and Gohan were traveling in, they appeared hostile at first but upon learning of our hero's intentions they let them go. These orphan's traveled the Northern Galaxy as "space pirates" in a mirror-like spaceship.

» Robots - Robot's are built and programmed to do whatever the creater pleases. We see a lot of Robot's guarding some kind of important objects. In DBZ we see Androids created by Dr. Gero which are a whole different thing. Robot's are usually much weaker and usually have 1 or 2 very simple objectives at hand.
