A warrior race from the stars. Saiyan's were an enslaved race used to conquer the universe and when their retaliated against their enslaver they lost their homeworld. To see a Saiyan is a rare sight but it is one that isn't normally met with fondness.
A Saiyan's Tail
as a Saiyan you have a long tail that's typical wrapped around the waist. If grabbed the Saiyan would be treated as if its been paralyzed till released. At 4th level this ability can be treated as ignored. If the character were to lose their tail it grows back after a month of in game time. Some say that if a Saiyan were to lay eyes on a full moon something of interest would happen..... At a price.
A Saiyan's Pride
Saiyan's strive to battle stronger and stronger opponents, anyone that can challenge them and provide a challenge. When a Saiyan would be knocked out they heal 1 d10 and get an unarmed opportunity attacks instead. You can use this once per long rest. At 3rd level you heal 2 D10. At 5th level you heal 3 D10 and get 2 unarmed opportunity attacks. At 10th level you heal 5 D10, get 3 unarmed opportunity attacks, and can use this twice per long rest.
Warrior's Gear
Saiyan's while enslaved grew accustomed to wearing the battle gear given to them by their enslaver giving them proficiency in light armor. Light Armor is also treated as unarmored.
A Warrior's Spirit
Something about Saiyan's draw them to other stronger individual's whether they are aware of it or not. A Saiyan prefers to let their fist do the talking for them. They gain proficiency in unarmed attacks allowing you to use D4 for unarmed strikes and giving you +1 D4 per character level for damage. For example a lvl 1 Character uses 2D4 for unarmed Strikes and a lvl 5 Character would use 6D4 for damage.
