Species: nihallaks (species)
Nihallaks are an antediluvian (incredibly ancient and/or existing from before the first Apocalypse) race of octopus-like, transdimensional aliens from the erotic webcomic fairies_vs_tentacles.
All nihillaks are male-personality hermaphrodites, possessing several tentacles, which are imbued with nanomachines that allow them to shapeshift into any number of tools (including penii), and a single ovipositor. However, most Nihillaks are flash-cloned, with only the Emperor allowed to breed normally.
Nihillaks feed on an energy known as F.A.P.S. (Fundimental Aura-Power Surges), which is generated when certain creatures experience sexual pleasure; analogous to Mana from non-erotic fantasy works.
