The Saiyans are ruthless. They love to battle and become stronger. They lived on the planet Vegeta until it was destroyed by Freezer to keep the Saiyans from uprising. He also feared that the Super Saiyan legend would one day turn real. When a Saiyan recovers from injuries of battle his power is increased to make him even stronger. This is an advantage for the Saiyans on their enemies. Saiyans have a tail, when they see the full moon light they transform into Were-Monkeys, also known as Oozaru. This is their strongest form other than Super Saiyan. Without there tail they can't transform. They send babies to weaker planets, such as Goku, but he suffered from amnesia, and could not remember his duties on the planet earth. Adults were sent to stronger planets.

They are a peaceful race with green skin and antenas. Nameks have the ability to enlarge themselves to any size and to stretch their arms to a size which even man can't imagine. They can also replace their body parts (if they loose an arm they can easily grow it back in seconds). One part of the body they cannot regenerate is their head, so if their head is blown off, thats it. Nameks are a unisex race (no female, no males?). Namek children are born in eggs and hatch minutes after birth. The Nameks are responsible for creating the dragonballs.
