Vex was a sentient rahi makuta Tridax created to be his assistant. He also reduced his intelligence as a prevention of him rebelling. Vex is usually very calm. The only real powers Vex gave him was enhanced agility, endurance, speed and strength. reason for the increase of his strength was he is often used by tridax to test new rahi or eliminate failed creations. his claws also have a type of poison that will drain the energy from any being that he scratches. unlike most energy draining powers it does it at such a slow rate that the infected being will not notice until it is too late. and any energy drained is transferred to vex no matter the distance. for the poison to fully take effect it depends on the victim but for toa it usually takes 2 weeks. the only other natural weapon he has is his left hand which is completely made of protosteel and with one hit from it a kane-ra will be subdued.
