The Mantis

Lore & Background

The company's moon-lease agreements make no mention of the Mantis, and the employee briefing tapes treat it with the same flat, bureaucratic tone they use for weather warnings: 'Entity class: Mantis. Behavior: stationary. Recommendation: do not approach.' There is no recorded origin, no specimen file, no containment protocol. It simply exists on certain moons, wedged into alcoves, perched atop corroded catwalks, or half-buried in the grey dust between shipping containers. Its exoskeleton is a sickly pale green, almost bone-white in the flat moonlight, with long, jointed legs that anchor it to the ground and the two oversized forelimbs folded together in front of its bulbous, compound-eyed head like a pair of scythes held at rest.

Employees who have survived a Mantis encounter tend to describe the same sequence: a moment of stillness that feels *wrong*, the ambient hum of the moon's generator suddenly seeming too loud, and then the shriek—a sound so sharp and close it registers more in the chest than the ears. The lunge itself is over in a fraction of a second. Those who get hit describe the forelimbs closing with a crushing, scissoring force, the compound eyes reflecting the overhead work-lights in a dozen tiny points of green. Those who survive usually owe it to a teammate who grabbed their arm at the last second or a lucky stumble that put them just outside the reach.

What makes the Mantis psychologically distinct from the other named entities is its patience. The Hound runs, the Stalker stalks, the Widow descends. The Mantis *waits*. It can sit motionless for an entire shift, and players who have already cleared the immediate area and are walking back toward the extraction point are often the ones who trigger it. It punishes the moment you stop looking, the moment you assume the threat has passed. In the company's unspoken employee culture, the Mantis is the reason nobody walks back through a dark corridor with their back to a wall.

In Their Own Story

The generator hummed its low, oily note. Kael's boots crunched on the thin layer of grey dust, and the overhead sodium lamp cast everything in a flat, sickly amber. The crate stack was clear. The catwalk was clear. He was three steps from the airlock.

Then the hum stopped. Not faded—*stopped*, as if someone had reached into the wall and pinched the sound shut. The silence that followed was so complete he could hear the blood moving in his own ears.

He turned. Forty metres back, in the shadow of a collapsed support beam, something pale and jointed sat with its forelimbs folded. The compound eyes caught the amber light and held it, a scatter of green pinpricks. It did not move. It did not need to. It had been there, Kael realised with a cold lurch in his stomach, since before he'd started counting crates.

"Kael. *Kael.*" Mira's voice cracked over the comms, thin and far away.

The shriek hit him like a physical blow, a needle of sound driven straight through his sternum. The pale thing *unfolded*, those scything forelimbs sweeping outward in a single, impossibly fast arc, and the last thing Kael registered before the world went white and green and *crushing* was the faint, almost gentle click of the exoskeleton segments settling back into place, as if the strike had been the easiest thing it had ever done.

Mira found the comms unit in the dust an hour later. Still transmitting. Still humming.

Reader's Guide

The Mantis – a pale, greenish-white insectoid with oversized raptorial forelimbs, a bulbous compound-eyed head, and long anchored legs, sitting perfectly still in a fixed spot on the moon's surface.

It does not patrol. It does not chase. It picks a position—usually a shadowed alcove, a gap between crates, or a spot under a broken catwalk—and it *stays*. You will not hear it moving. You will not see it twitching. It is essentially invisible unless you are actively scanning dark corners for a pale, segmented shape with two large folded claws. The moment a player enters its strike radius, it shrieks—a loud, high, piercing screech that cuts through the ambient noise—and lunges in a single, extremely fast arc. The forelimbs close with a scissoring, crushing motion. A direct hit is typically lethal or near-lethal. The lunge is over almost instantly; if you survive, it resets and goes back to waiting.

What lures it: proximity is the primary trigger. Walking within its radius is enough. Loud, sustained noise (running, shouting, the rattle of a full crate) can carry you into range even if you are not looking directly at it. Some players report that the small Lure device, when activated, can draw a player's *attention* toward a Mantis position, which is useful for identifying where it is sitting before you accidentally walk into it.

What helps: awareness. Check dark corners, gaps between structures, and the undersides of catwalks before you commit to a route. If you hear the shriek, you are already in the lunge—your only chance is to be just outside the arc, which means you should have been watching. A teammate grabbing your arm, a stumble, a wide step: small margins save lives. There is no reliable way to "repel" it or make it leave its spot. You do not fight the Mantis. You avoid its radius.

Field note: *"It's not the thing that chases you that gets you. It's the thing that was already there. Check the corners. Always check the corners." – Employee 4471, post-shift debrief, Moon 07*

Did You Know?

• The Mantis is one of the few named entities in Lethal Company that does not actively pursue a player; its entire threat model is built around a single, stationary ambush, making it uniquely punishing for players who stop
• Its signature shriek is one of the most instantly recognisable audio cues in the game—players in co-op sessions often report hearing it and immediately calling out the Mantis's position to teammates before they've even s
• Because the Mantis does not reset its position after a lunge, a single well-placed crate or piece of debris can block its strike arc, and experienced crews have been known to use environmental geometry to create a narrow
• In the game's co-op design, the Mantis is particularly deadly to the player who is lagging behind the group or walking back through an already-cleared area, since it punishes the exact moment a player's attention drops.
