Sheargas is the Nemetrix's DNA sample of a Hirvëaasu from X' Nelli and the predatory species of Polar Manzardills.


Sheargas is a massive animalistic alien. Its skin is primarily white, with grey hands and lower body, which is also supported by five tentacles. Its face is protected thanks to skin folds around it. It has small, red eyes and a mouth with serrated teeth. Its back is covered by multiple large yellow cysts containing gas.

Sheargas wears the Nemetrix on a spiked red collar around its neck.

Powers and Abilities

Sheargas can release a yellow gas from the cysts on its back, that is able to clog a Polar Manzardill's airways, preventing them from breathing, much less utilize their frost breath.

Its sharp teeth and claws can tear through a Polar Manzardill's shell with ease.

Sheargas is highly resistant to low temperatures and is unaffected by a Polar Manzardill's frost breath.


Sheargas is not particularly fast, being an ambush predator.

High temperatures can cause Sheargas great discomfort.
