Perpetual

Perpetuals are a lesser-known form of mutant in the Warhammer 40,000 universe who possess immortality, among other superhuman abilities. Whilst not all were born with these abilities, some gaining them through artificial genetic intervention using advanced technology, every perpetual never aged and was capable of healing almost any injury. Whilst this process can take up to a year to fully heal, some Perpetuals have been known to survive such injuries as dismemberment, decapitation, suffocation and directed energy assaults, even after being declared clinically dead.

Only one way is known to permanently kill a true Perpetual, that being a spear-like artefact known as the Fulgurite. This weapon was created as a by-product of the Emperor of Mankind's psychic lightning fusing sand on the planet Traoris, after his forces liberated it from Chaos cultists during the Great Crusade. Due to retaining a portion of the Emperor's power, the mineral used to create the Fulgurite was capable of overcoming the natural regeneration of a Perpetual.
