Saiyans are a powerful mercenary shapechanging race composed almost entirely of warriors. They sell their services to the highest bidder, and frequently take over entire planets in order to sell salvaged goods, people captured to be used as slaves, and even the planets themselves to whoever is willing to meet their price. This warlike race is unmatched in power and brutality.
Saiyans are powerfully built, with wild hair and dark eyes. For the most part, however, they look frighteningly human, and are unable to be distinguished from humans by the untrained eye.
What makes the Saiyan race even more frightening, however, is their ability to transform into colossal apes in the light of a full moon. When in their Oozaru form, they destroy everything and kill everyone in their paths, leaving a wake of death and destruction.
COMBAT
Saiyans have a natural gift for fighting, able to fight unarmed just as a monk, and also able to defend himself or herself as a monk could as well. Saiyans live to fight. Saiyans rarely do anything other than fight directly in combat, not caring for the use of tactics when power will usually suffice. A Saiyan is rendered powerless, however, by grabbing its tail.
In Oozaru form, Saiyans merely smash and eat everything in sight, using its devastating breath weapon on those out of reach. These terrible monsters are ten times as powerful as a normal Saiyan, and are nearly impossible to defeat in physical combat. Only by removing the light of the moon or cutting off the Saiyan's tail can the Oozaru be forced back into its normal Saiyan form.
Oozaru Form (Su): In the light of a full moon, Saiyans revert to a primordial state in the form of a colossal ape. In this form, the Saiyan is in a constant state of rage, and will destroy anything and everything around it. A Saiyan must have his or her tail to transform. When the light of the full moon is gone, the Oozaru will change back into its normal Saiyan form. Removing the tail of the Oozaru also causes the Saiyan to change back to his or her normal form. A Saiyan in Oozaru form receives maximum hit points per hit die upon transforming.
Breath Weapon (Su): While in Oozaru form, a Saiyan is sometimes attacked from afar and unable to pummel or eat the attacker. Sometimes a Saiyan in Oozaru form is simply in a really bad mood. In these instances, the Oozaru breath weapon is invaluable. Line of energy, 400 feet; damage 1d10 per HD/level, Reflex half DC 28.
Monk Abilities (Ex): Saiyans attack as monks, using the monk's favorable number of attacks per round, as well as dealing damage as a monk of a level equal to the sum of the Saiyan's hit HD and levels. Saiyans also gain the benefits of the Improved Unarmed Strike Feat, as well as access to the monk's Flurry of Blows and Stunning Attack, and they gain the Stunning Fist feat for free. In addition to monk attack forms, Saiyans gain a bonus to their AC as monks of a level equal to the sum of the Saiyan's HD and levels, including a Wisdom bonus to AC whenever applicable.
Tail Weakness: By grabbing the tail of a Saiyan, you can stun him or her. This condition lasts as long as the tail is tightly held. This is ineefective again a Saiyan in Oozaru form. If a Saiyan's tail is removed while he or she is in Oozaru form, he or she immediately changes back to his or her normal form. Whenever a Saiyan's tail is removed, he or she must succeed at a Fortitude save (DC 30) or be stunned for a number of rounds equal to the amount the save was missed by, double that number if a natural "1" is rolled. The tail has a 1 in 6 chance of growing back in 1d12 months two weeks before the next full moon. Without his or her tail, a Saiyan's loses 8 Strength and 4 Constitution, and is unable to transform into an Oozaru.
Power Adaptation (Ex): Saiyans are very hard to kill, and only gain more power if they survive an otherwise fatal attack. When a Saiyan is reduced below 0 hit points, once he or she recovers, he or she gains 100 experience points for each point below 0 he or she went, and receives a permanent cumulative +1 bonus to Strength and Constitution; if the added experience points give him or her enough to gain a level, he or she gains that level immediately. For example, if a Saiyan is reduced to -8 hit points and then healed with a Heal spell, the Saiyan immediately gains 800 experience points. If the Saiyan had 189,500 experience points before, he now has 190,300 experience points and gains a level. *A Saiyan can only be killed by reducing it to a negative number of hit points equal to it's Constitution score plus its total Effective Character Level. In other words, if a Saiyan has three character levels and a Constitution score of 16, he or she must be reduced to -34 hit points to be killed.
*In the Chaotic Worlds campaign, all character follow this rule. In the Chaotic Worlds campaign, Saiyans are harder to kill due to the Saiyan's Toughness feat.
NEW FEATS
Saiyan's Toughness [Saiyan]
You're a Saiyan, and thus much tougher than most other races.
Prerequisites: Saiyan
Benefit: You gain +36 hit points and your "death's door" range is doubled. This is applied before all other modifiers, including other feats in the Toughness chain of feats.
Tail Weakness Immunity [Saiyan]
You have surpassed the normal limits of a Saiyan warrior and have become immune to the Tail Weakness shown by other Saiyans.
Prerequisites: Saiyan, Tail Weakness trait, character level 9th+
Benefit: You are immune to all of the effects of Tail Weakness. You are still unable to transform into an Oozaru without your tail, however.
SAIYAN SOCIETY
Saiyans are an extremly militant race. Saiyans live for war, fighting, and power. Only the strongest survive, and the strong will rule over the weak. Saiyans are loyal to the most powerful of their kind.
Saiyans are well organized in fighting armies, all with extreme amounts of power. Saiyans' teamwork is second to none, but if one shows weakness, his or her comrades will show no remorse in disposing of the weakling. This race strived to increase their power in the universe, and will routinely take over planets, strip a planet of its natural resources, kill all opposing males, take opposing females as slaves for harems, and sell opposing children into slavery. Most Saiyans are pure evil. although because of their warlike nature, many die before fulfilling their true potential.
Saiyans usually live approximately as long as humans do.
SAIYAN CHARACTERS
A Saiyan's favored classes are fighter and martial artist (a monk variation), and Saiyan leaders tend to be fighter/martial artists and fighter/monks.

The Effective Character Level of a normal Saiyan is +15.
