The Vorox are known to shift from liquid to solid and vise versa, naturally they start off as liquid morphs and shift into a solid design, though it seems to take 'effort' in shifting back into a liquid state. When expired the Vorox seems to 'stiffen' and harden. Which is where the Necrosis comes in, considered a form of 'Royal' breed, the Necrosis seemed to have formed as a form of recycling dead materials, its body seems to be design to process this material into a vapor similar to that of the 'Spire' and other Female 'Royals'. However the Necrosis seems to be a variant of the male breed of 'Royals'.

Normally the creature would remain underground until needed, though vision is fairly poor, they can feel vibrations from the ground to detect hostile creatures. When harmed the creature can used its powerful jaws to rip apart even the most durable metals. It can also use its vapor production to posses near by creatures for a moment. Naturally the creature consumes all form of bio matter even those that are controlled by the creature.
