An arthropod-like creature that thrives in the submerged section of Sector 4. The Evir-X is capable of expelling yellowish globules from its tail apparatus by rapidly contracting its abdomen. They have an incredibly thick exoskeleton, making them more vulnerable on the front of their body. Their coloring is orange and yellow, which is different from their Maridia incarnation, likely due to the X-Parasite's pseudo-mimickry.
