A Sayians body is made for brutal physical combat, as such they gain resistance to blunt damage, and have advantage on death saving throws.

A Sayian fights with his bare hands, having to proficency in any weaponry, but doing 1d10 in unarmed, 2d10 at level 7, and 3d10 at level 15.

Sayians are a species born for battle, and as such get stronger with each fight. Everytime a Sayian is reduced to 0 or less than 0 HP they recieve +3 "S Cells", these points stacking for as long as the Sayian may live. As well as an amount of XP to be determined by the DM.

When a Sayian looks at the full moon they turn into a gaint Ozaro, becoming Gargantuian in size, gaining a height of 50ft, and a weight of 6000lbs. A DC of 12Wis must be passed or the Sayian goes berserk and loses control. 

A calm mind and a pure heart, flooded with rage. A summons of power uncontrolled. A burning desire to protect and avenge, an overwhelming surge of power to change the future, the rage brought forth from a shattered pride or a fallen comrade. Life of battle is one of pain and struggle, but if not for that pain and struggle a Sayian could never reach their full potiental. 

When a Sayian has accumulated enough S-Cells and they experience a tramatic event, one where they arent strong enough to help, they undergo a powerful and destructive transformation.

"False Super Sayian" The first form a Sayian has access too, and only to be used once when the Sayian needs the power of a Super Sayian but lacks the power to ascend. This form is far more destructive than other forms as is it a psuedo-transformation meant to be used in an emergency. Whilst in this form, a Sayian gains 1 level of exhaustion every round, up until round 6, at which the Sayian dies. Whilst in this form all stats raise to 20, however, after this form wears off all stats suffer a -2 penalty for the next 72 hours. Any stats beyond 20 do not change.

"Super Sayian 1" The most basic form of Super Sayian, not to be mocked or belittled, as even this basic form weilds immense power. The requirements for obtaining this form are a 20 in any 3 of the following: (STR, CON, DEX, WIS, or CHA) In addition, one must experience great emotional pain and suffering to ascend, as well as have accumulated at least 30 S-Cells. Whilst in Super Sayian 1 your movement speed doubles, and you gain the ability "Flurry of Blows" and can attack as a bonus action.

Whilst in this form you suffer 1 level of exhaustion every round, loosing the form at round 5, falling unable to move. 

"Ultra Super Sayian" A form that prioritizes damage and power over speed. Upon going SSJ1 you gain access to this form. Whilst in this form, your STR and CON rise to 25, but your DEX drops to 12, as well as your speed halves. You gain a +7 to hit, as well as 3d8+10 blunt damage to melee attack rolls. This form is more taxing than SSJ1, only lasting 3 rounds before falling to level 5 exhaustion.

"Mastered Super Sayian" One can meditate in the SSJ1 form to gain mastery over it, mitigating some of the cons in exchange for diminished rewards. In MSSJ1 your movement speed is upped by a factor of 1.5, and you can attack as a bonus action. You gain a bonus 3d6 to blunt melee attacks, as well as a +4 to hit. Your ability scores rise to 18, but anything above stay where they are. You only suffer 1 level of exhaustion every 2 rounds, losing this form after 10 rounds.

"Super Sayian 2" Being at your limit, but needing to go even further beyond, having no more stregnth, but still needing to fight. Having everything you hold dear cast aside infront of you and having nothing left but unbridled rage, You feel your Sayian blood boil once more as you break through a barrier and forge ahead into a new level of Sayian power. This form is a Super Sayian form unlike the previous forms, brought upon by rage beyond anger, your first transformation is uncontrollable, feeling pure animosity for whatever forced you to go beyond, amd solely seeking their death.

You gain "Flurry of blows" and can attack twice as a bonus action. You gain a bonus 2d12+12 blunt melee damage. Your speed triples as well as gaining 1 level of exhaustion every round, collapsing on the 5th. 

"Legendary Super Sayian" Once every thousand years a Sayian of legend is born, but even amongst them a prodigy of destruction incarnate is found only once in an eon. A being whose raw destructive power and malice are unmatched, even among a race of cold blooded killers. Born with the power to shake the heavens themselves, and only growing stronger as time passes, their power constantly building, overflowing, growing more and more unstable. These vile creatures, feared even by their own people, have no morales, and do as they please, when they please. Only a chosen few can go LSSJ, and chosing this path ends your advancement here, blocking you from further forms. As a LSSJ you lose control of yourself in the face of battle, going into a mindless rage of bloodshed. You become unable to discern friend from foe, and a DC WIS  of 19 must be made to prevent you from attacking your allies. Whilst in LSSJ you constantly gain power, your speed remains x2 its base, but your ability scores rise to 20 and gain 1 every round you stay in this form, you do 1d12+2 extra damage to all damage done, and gain a +2 to hit. This rises every round, becoming 2d12+4 and a +4 to hit on the second round, 3d12+8 and a +8 to hit on the third, and so on, until you are defeated or the 6th round, if you hit round 6 your power rises beyond your control and you expell all your built up energy in one massive blast that deals 15d12+60 explosive magic damage to the surrounding 500ft, with no saving throw to avoid. After this blast you collapse, dead, only ressurrected by a wish spell or similar feature.

"Super Sayian 3" Only a true warrior who has pushed their body and spirit to the limit can even begin to fathom this form. The very apex of a Sayians natural power progression, all the potential a Sayian has, coalessed into this form and given physical presence. Tapping into the limitless pool of energy every Sayian is born with, SSJ3 is the highest tier of power a Sayian can achieve without outside help. To obtain this form you must have mastered SSJ2 for at least 6 months, and passed into the afterlife at least once. It takes 3 rounds to charge your energy to transform.Whilst in this form, all your ability scores rise to 30, and your speed is x6. You gain "Flurry of  blows" and can attack four times as a bonus action.

"Super Sayian 4" When a Sayian is transformed into Ozaro form, and then ascends to a level of Super Sayian, something horrificly awesome occurs, that sayian becomes a Golden Ozaro, gaining the benifits of both the SSJ1 form and the Ozaro state. However, the unholy union of primal rage and golden heart doesnt end there. If that sayian is then exposed to amplified levels of Blutz waves, like those generated by the moon, and is then able to take control of themselves with a DC of 20 WIS, they undergo a transformation unlike any other SSJ form in existance. Shrinkiny and regaining a humanoid form, but retaining the beastlike power and features of the Great Ape that lives within, a Sayian obtains the SSJ4 form, and can then use it as a SSJ transformation. Only a Sayian who has kept his Tail may go SSJ4. Whilst in SSJ4, all ability scores rise to 28, and your base speed is x6. You gain the feature "Flurry of Blows" and can attack four times as a bonus action. It takes 4 rounds to transform. You deal an extra 6d12+20 blunt melee damage. You gain 1 level of exhaustion every 2 rounds, collapsing unconcious on the 10th. 

"Super Sayian God" A form that trancends mortal limits, and gives a Sayian the power of a god. Only by having 3 gods embrace them and then focusing their power in the Sayian can a being ascend to god-hood. This form is lighter and faster than any other form, but lacks the rage and power of the more primordial forms. You gain 3 legendary resistances, as well as a x10 speed increase. All your stats rise to 20, and you gain 2d10+15 melee damage. You gain "Flurry of Blows" and can attack 2 times as a bonus action. This form gives no exhaustion per round, but can only be maintained for 4 rounds before the borrowed energy is lost.

All Sayians are born with a tail that they can freely manipulate, it acting as a 3rd arm, being able to hold their STR score in lbs. Having the tail makes a Sayian succeptable to the Ozaro transformation, but also gives advantage on athletics and acrobatics. The tail can be cut, but will regrow in 1d12 months.
