Weaknesses

 * Training: A Saiyan's body can only maintain its peak form as long as they rigorously train. It is shown that if a Saiyan lapses in their training, that simple weapons such as pistol bullets can easily pierce their skin.
 * Tail: As a Saiyan is naturally born with an extra appendage, it becomes a notable weakness. With the tail still attached, a Saiyan can be disabled by gripping the tail and pulling it. The tail can also be easily severed. By servering the tail, a Saiyan can no longer transform into either a Great Ape or a Golden Great Ape.
 * Moonlight: While a Saiyan can utilize Moonlight, or rather large planetary reflections, to turn into a Great Ape, it can be detrimental. An untrained Saiyan can accidentally transform and cause destruction to friend and foe alike until the end of the exposure or until the tail is cut off. A trained Saiyan, while able to retain their intelligence, can still be at a disadvantage due to the size.
 * God-Level Energy: While Saiyans excel in detecting energy, they cannot sense any energy emitting from a deity.

History

The eventually caused the planet to begin to self-destruct, leaving the Saiyans without a home. They utilized their galactic travel and war knowledge to take a new world as they where led by the first King Vegeta. The planet in question was Planet Plant, who's inhabitants where peaceful. Following a successful planetary take over, the Saiyans renamed the planet to Planet Vegeta, and became known as intergalactic mercenaries, taking over planets for money.

However, the galactic terrorist, King Cold, found that absorbing the Saiyans into his empire would be highly beneficial. The terrorist overwhelmed the more primitive Saiyans, and made them his war-slaves. Forced to serve as planet conquerors for King Cold, the Saiyans became mere foot soldiers even the current King Vegeta and Prince Vegeta where forced to serve.
