Races

Android
Homeworld: Earth
Androids consist mostly of artificial parts, but a human look. There are three types of Androids in DragonBall-DragonBall Z: Androids with a human base that rely on an internal power source, Androids without a human base with an internal power source, and Androids with a human base that rely on power absorbing nodes in their hands. All androids in the series are produced by the Red Ribbon Army.

Bas-Jin
Homeworld: Unkown
A short and stout race. They have four-eyes and are telepathic. Guldo is an example of this race.

Changeling
Homeworld: Frieza
The name pretty much gives away what these beings can do. All that is significant, is that these creatures can change to many different forms, usually increasing their power level at each stage.

Dragon
Homeworld: Unknown
The mystical dragons can do a variety of things, some can control elements of nature, while others can act as god and grant wishes. Every Dragon looks different, and some don't look like dragons at all.

Kaio
Homeworld: Heaven
Lesser gods of the universe, Kaios are immortal beings that live in heaven. We only see the Kaio from the North in the series. The rest are unknown, maybe destroyed when Buu destroyed most of the Kaioshins. The Kaios are notorious for their pride and stubborness, but they rarely let it get the better of them.

Kaioshin
Homeworld: Heaven
Rulers of the four galaxies, the Kaioshins are immortal creatures that watch (and protect) their terraria. All the Kaioshin, but the East Kaioshin is wiped out by Buu's rampage. They are not strong, but they have a great influence over the galaxies.

Makyo-Jin
Homeworld: Makyo Star
The creatures are rather odd. They are a light green color, and look like goblins. They really possess no special talents, except when the Makyo star can be seen from any location, they increase in size and power. They beef up to a pretty massive form, and are at least ten times as strong as they originally were.

Namek-Jin
Homeworld: Namek
These wierd green creatures possess not only the power to create their own dragons, but have warriors with awesome skill. Most Nameks have a special talent, that mostly no other beings have, for example, Piccolo has the power to regenerate, and Dende has the power to heal anyone or anything in a matter of seconds.

Saiya-Jin
Homeworld: Planet Vegeta
A brutal, physically strong race of beings, the Saiya-Jins were a race of conquerors and bandits on Planet Vegeta. Their rivals, the Tsufuru-Jin, attained the goal of keeping the Saiya-Jin race from wiping them out, do to their technology. However, all it took was a full moon on Planet Vegeta for them to conquer them. Their ignorance caused their race its demise when they refused to listen to Bardock's warning about Frieza. Their homeworld was blown to bits, and very few of Saiya-Jins survived. All members of the race possess the ability to go Oozaru and SSJ, though few can even manipulate that power.

Tsufuru-Jin
Homeworld: Planet Vegeta
These frail beings are very intelligent and native to the Planet Vegeta. Yet do to their intelligence they protect their terraria from Saiya-Jin, using their technology. They are highly advanced, yet are no match for Oozaru.

Yardrat-Jin
Homeworld: Yardrat
Here's a race that can manipulate time and space, they play a brief (but very important) role when they teach Goku how to use Instant Transmission. Goku ends up on their world when he finds one of the Ginyu pods right before Namek explodes. He gets off the exploding planet, just in time. Only to crash land onto Yardrat.
