Zain is a servant of Razlo the Tri-Punisher of Death and a member of the Eye of Michael who wears what appear to be a environmental hazard suit. He carries one of the Punishers while Livio's persona is active. He, along with the other two servants, obeys Razlo's commands seemingly without hesitation or fear, and is seen to be adept in the use of throwing knives and explosives. He also appears to be capable of reviving himself with the use of a strength-enhancing liquid, dispensed from cylindrical reservoirs on his backs. He is last seen in Trigun Maximum vol. 10; he appears to die when Livio's personality reasserts itself as his dominant mindset.
