Saiyans - In Japanese the correct spelling is Saiyajin (or Saiya-jin). They are half-human, half-monkey creatures. The Saiyan home planet is Planet Vegeta, which was destroyed by Freeza. There were only seven known survivors. All Saiyans are born to be a fighter, it runs in their blood. True Saiyans have tails attached to them, just like monkeys. When a Saiyan sees a full moon, they turn into an Oozaru. When a Saiyan is in Oozaru mode their power increases 10x. Very strong Saiyans such as Goku, Gohan, Goten, Vegeta, Brolly can turn into a Super Saiyan. There are 5 Super Saiyan stages that Saiyans can go and on top of that two Oozaru stages. They are Super Saiyan, Ultra Saiyan, Super Saiyan 2, Super Saiyan 3, Super Saiyan 4, Oozaru, and Golden Oozaru.
Nameks - Nameks have green skin and antennas on their head. and their race only contains of males. Nameks can do a special fusion where one Namek gets absorbed into the other Nameks body. In this combined form the two Nameks power level combine. Only certain Nameks can create Dragonballs. Each dragon can only make a wish within the Nameks power. When a Namek creates Dragonballs, the Dragonballs are created so that it will fit well in the creators palm.
Majin - All Majins are charmed by Babidi. When Babidi charms a character, they become Majin. All Majins have a "M" somewhere on their body/clothes. Vegeta only became Majin because he let Babidi charm him and this was the only way for Vegeta to fight Goku and see who was more powerful.
Humans - The people that are normal live on Earth. The sole purpose of this race in DBZ is to run around screaming. The only humans that don't run around screaming are the main characters.
