The Stroyent processing Creature is a large and excessively corpulent partially-stroggified creature, which is being used by the Strogg as a vital part in their Stroyent production operation at the Putrification Center.
The creature is force-fed with raw Stroyent, which is then somehow processed within its stomach and digestive system in order to become ready to use. The creature is one of the five bosses in Quake 4 along with the Makron, Network Guardian, Voss and Nexus.
During the later stages of the War against the Strogg, the stroggified space marine Matthew Kane encountered this creature and had to evade its dangerous metal claws. He eventually defeated it by overfeeding it, causing its bowels to burst and blowing open a hole in the floor, allowing Kane to escape.
- The sound that the creature makes when its stomach bursts is the same sound as Maledict from Doom 3 makes.
- Despite its stomach and abdomen being blown wide open, the creature continues to move as if breathing after its defeat, suggesting that it still somehow lives, and that it may in fact be "repaired" by the Strogg to continue its unpleasant duty.
