Saiya-jin: a warrior race of people with tails who inhabited the former planet "Vegeta" from 550 to 737 A.D.   The saiya-jin are people characterized by tails, often wild hair, and a love for fighting so deep it seems bred in their genetic structure.  Even the youngest saiya-jin babies have the strength to conquer many other races, especially on nights of a full moon when a saiya-jin undergoes a dramatic transformation into a giant wereape known as an "Oozaru".

The saiya-jin landed on the planet then named "Plant" in a mysterious ship approximately 550 A.D.   They lived in a basic, wild manner apart from the planet's dominant race, the Tsufuru-jin.  Scattered bands of saiya-jin inhabited the outer, unclaimed areas of the planet for decades, living, fighting, and existing solely among their own.

In the year 720 A.D. the saiya-jin united as a race and began a ten year war against the Tsufuru-jin for control of the planet.  The Tsufuru-jin, while smaller in stature and brute strength, were technologically advanced and fought back against the saiya-jin, until an event that only happened every eight years on Plant took place - a full moon.  The saiya-jin, now able to transform into their giant and even more powerful Oozaru state, had no trouble decimating the largest portions of the Tsufuru-jin race.

By 730 A.D. the saiya-jin had taken control of the planet and re-named it Vegeta.  The were quick to adapt the Tsufuru-jin technology to their own way of living, increasing their abilities to the point of space travel.  Once the barrier of space was breached, the saiya-jin began meeting aliens from other planets.  These aliens quickly learned how useful the natural strength of a saiya-jin was for capturing territory, and in 731 A.D. the saiya-jin began a partnership with the strongest of those aliens - a galactic dictator named Freeza.  Under this new partnership, the saiya-jin had a new duty added to their daily lives - the conquer of other planets slated for sale in the planet trade.

This same year King Vegeta married his queen, and a year later in 732 A.D. a young prince was born bearing the name of his father and his home world - Vegeta.  This boy was born with an outstanding power level, marking him not only as an elite fighter from birth but also as a potential super saiya-jin - a legendary figure that had not been seen in so long many people considered it only a myth.

This calm existence was not to last, however.  By 735 A.D., Freeza had begun to feel misgivings toward the saiya-jin, and feared the possibility that a super saiya-jin truly could be born among them.   Fearing that such a being would possibly be able to topple his empire and strike him down, Freeza began to keep track of the saiya-jin and their abilities.

In 737 A.D. a baby was born to a third-class warrior named Bardock.  An uneventful birth to a man who was a busy warrior, except for the fact that the baby was born with an astoundingly low power level.  He was named Kakarott.  His father had no interest in such a weak baby and focused on his job of clearing the planets Meat and Kanassa, while Kakarott was bundled into a small space pod and sent to Earth.

Unbeknownst to most saiya-jin, Freeza had forced King Vegeta to hand over the Prince to him, in exchange for ensuring the safety of Planet Vegeta.  King Vegeta quickly realized the mistake he had made and took a select group of elite fighters to Freeza's ship in an attempt to overthrow Freeza and take back his son.  The revolt failed when Freeza killed King Vegeta with a single blow and then finished off his elites.  Freeza demanded the death of all saiya-jin; Dodoria was dispatched to kill Bardock and his crew on their current mission while Freeza headed toward Planet Vegeta.  Dodoria was only partially successful, and Bardock, having realized the fate of Planet Vegeta both through the words of his dying teammate and his own visions, raced back to Planet Vegeta, where he died trying to protect it.  The same blow also ended the existence of Planet Vegeta.

But, saiya-jin are noted for their strength, and their race shall endure.
