Spiner

The Worxerians were a race of nearly extinct bipedal porcupine-like humanoids. They were capable of hurling these with great speed and accuracy by flexing their muscles in a certain manner. Their native world, Worxer, was destroyed when its sun went supernova. The surviving population gradually became sterile for a lack of nutrients found exclusively in their home sector of Elrood.

Skills and abilities
Worxerians were covered in stiff barbed quills, the longest of which grew on the arms and legs, and could reach a length of several centimeters. Worxerians possessed the unique ability to propel these quills by simply flexing specific muscles, which could propel the quills with incredible speed and accuracy up to ten meters away. Worxerian quills themselves are extremely hard, as shown by Hedji when he attacks and kills a High-hound, as well as several Cloud-Riders - lending to the quills ability to pierce skin, clothing, and light armor with sufficient force as to kill. Worxerians additionally had extremely quick metabolisms, and were capable of spontaneously growing more quills as needed; a Worxerian could easily expend hundreds of quills during the course of a fight.
