The Mantis is a Hardmode enemy which spawns on the Surface Astral Infection biome. It chases the player on the ground, gaining speed if continuously running in one direction, slowing down when turning around, and hopping if it encounters a gap in the ground or a change in elevation. If the player is on the ground and close enough, it briefly stops and fires a short-ranged spinning scythe projectile at them.
- The Bestiary entry for the Mantis: "A nimble mutation of the astral infection, its many legs allow it to quickly traverse nearly any terrain the infection devours. By swinging its front claws at high speeds, it releases harmful blades of energy."
- The Mantis' projectile is a reference to the projectiles fired by the Mantis Lords boss and Mantis Petra enemy in the game Hollow Knight.
