Are very powerful warriors who can power up by anger. Some Saiyans can become "Super Saiyans," including half-Saiyan hybrids like Gohan and Goten. A Super Saiyan is a transformation a Saiyan can go through and makes them stronger and changes their hair to blonde. Only a few Saiyans have the potential to become Super Saiyans. The legend goes, once every 1,000 years a Super Saiyan emerges. Saiyans play a very important role once it is revealed that Goku is one.
