Saiyans are an endangered race of extraterrestrials in Noah 10. In the series, the Saiyans are a naturally aggressive warrior race who were supposedly the strongest warriors in the universe. Nearly all of the Saiyans were obliterated by Frieza. The Saiyans are a group of barbaric aliens who shared a planet with a race known as the Tuffles. The Saiyans lived in the arid wastelands, while the Tuffles lived in great cities, employing advanced technology. One day however, the Saiyans attacked, vowing to conquer the Tuffle's great cities, and to extinguish the race. This sparked a ten year long war. It is revealed that when the Saiyans arrived on Planet Plant, they were welcomed by the Tuffles.
Saiyans are outwardly very similar to any other Humans, with the exception of their monkey-like tails and a larger muscular build. They are commonly seen to have deep black hair although there have been rare occasions when they have also been shown to have brown hair.
The Saiyan's one weakness is their tail. The tail is a particularly sensitive area for Saiyans who had not trained it. When grabbed or injured, it causes great pain to the owner, and temporarily immobilizes the whole body. However, Elite-class Saiyans trained themselves to overcome this weakness.
Not so weak
Although the tail is sensitive, it can help Saiyans grab things and climb places.
The Saiyans are named after the Japanese word for vegetable, yasai. Most Saiyans are named after Vegetables, even the planet is named after the word vegetable!
When Saiyans evolve, their hair becomes golden, and they become much more powerful.
