Xenomorph Boiler (Earth-5875)

Boilers are a form of bulbous and highly volatile xenomorph, first recorded by humans during the Mission to Paraíso in 2536. Unique among its other xenomorph brethren, Boilers discard the typical melee and acid spitting to rupturing its own body in a suicidal manner to kill nearby enemies with its blood.

Anatomy and physiology
Being 8' 0" (2,43 m) tall, Boilers have a deformed body, a result of its own decaying acid blood being spread across its body. As its name implies, the form is covered with postules that are boil-like in nature, which severely restricts their movement to being upright. Unlike all other known xenomorphs, Boilers cannot "see" and are effectively blind, instead locating targets and enemies through vibrations and suble sounds around them. They spend most of their time in immobile positions that resemble fossilized hunts. When an individual or animal approaches it will detect its sound and start to move to locate the source. When they move, the postules around their body glow and their dorsal tubes shake. They are extremely short-lived, and are prone to commiting suicide even when no victim is around. Once they locate their victims, Boilers will run at aggresive speeds in kamikaze fashion to explode and take out as many enemies as they can with their blood and explosion radius.

Intelligence
While xenomorph nature is still completely unknown to humans and other species, it appears that Boilers are less intelligent than their other xenomorphs. Unlike other forms, they are unable to properly see and walk into stealth manner, some of the species' biggest advantage against all kinds of enemies. Boilers also have short attention spans, and move on from their objectives in quick succession.
