Dark Mantis is a minor antagonist from Megaman X8. He is a new-generation Reploid who was given the role of head of security for an underground military facility but upon becoming a Maverick he used it to help produce weapons for the Maverick leader Sigma.

His design is based on a mantis. Because of this, his head possesses two large gems on either side similar to a mantid's eyes, along with the folded wings and scythe-like arms of one. His armor is predominantly gray, purple, and yellow in color, and he stands much taller than the Maverick Hunters.

Dark Mantis relies solely on stealthy attacks and utilizes his agility well. He can release boomerang-like "Shadow Runner" projectiles from his foldable arm scythes. Even in a desperation attack he focuses energy in his arm blades to even extend them for great cutting power.
