Inspectors, also known as Hydras or Axons, are creatures found in Iterator superstructures that act as protectors of Iterators' Neuron Flies. They vary in color and possess three heads attached to long necks.


Inspectors have three one-eyed heads attached to long necks that extend from a central body. The body has thin protrusions that vary in number between individuals arranged like a propeller, as well as trailing fibers similar to those on the red tendrils and surfaces throughout Five Pebbles’ can. Inspectors are blue in Five Pebbles and yellow in Looks to the Moon. They become red when enraged.



Attacking Slugcat

Fighting an Inspector can be challenging, especially when encountered in zero-gravity environments. Though their main body does not move quickly, this low speed is offset by the dexterity of their heads. Attacking one up close is risky, as Inspectors grab and throw any objects within their reach, including objects held by Slugcat, any Spears stuck in their tendrils, and Slugcat themself. Attacking from too far away, however, becomes impossible, as past a certain distance thrown Spears lose velocity and become harmless.

An Inspector can be killed by attacking their core, necks, or heads. Hitting their heads or necks with standard Spears or Rocks consistently deals 0.12 damage, which kills an Inspector in 8 hits. Since both deal the same damage, Rocks are the safer option, as Spears can be grabbed by the Inspector and used against their attacker. It can be helpful to hide extra Spears from the Inspector's sight before provoking them to prevent the Inspector from using them.

Most attacks on the core do no damage but have a very low chance to kill in one blow (0.1%). As such, focusing on the core with standard weapons is not a consistent strategy. However, explosives to the core are always lethal. It can be easier to use Explosives from further away, as an Inspector's necks can block a shot to the core.

It is possible for Artificer to stun and maul an Inspector, killing them instantly. This method is relatively safe, since deflecting near an Inspector does not provoke them, but it can be challenging to grab them in time due to the zero or low gravity environment they usually inhabit. Artificer is also prone to overheat from use of their Explosive Jump for both mobility and combat.


It can be challenging to sneak by an aggravated Inspector due to their multiple heads and erratic movement, though if Slugcat moves out of their sight, they become passive again.

Once an Inspector has been provoked, they keep attacking on sight for the remainder of the cycle, so the best course of action if one has been angered is to avoid contact as much as possible.


Although their attacks are fast, Inspectors are rather slow, making them easy to outrun. They can pursue the Slugcat between rooms but lose interest if the room's pipe is too far away or inaccessible.

Abilities & Behavior

Inspectors are initially passive, roaming through the zero-gravity environment. The fibers trailing on their bodies may reach out and contact fibers in the environment, lighting up blue at the ends.

Upon being approached, they use their tendrils to probe and feel Slugcat; this is harmless and has no effect on Slugcat.

If passive, Inspectors attempt to save Slugcat from stationary hazards, such as Proto Long Legs and flux condensors, by grabbing and throwing Slugcat away from them.


Inspectors become aggressive if attacked or if the Slugcat grabs or attacks Neuron Flies in their presence. They flash between red and white when angered. The state entered by grabbing a Neuron Fly is different to that of eating one or directly attacking an Inspector. Instead of trying to kill Slugcat, Inspectors pick up and drop items as if in warning and attempt to dislodge the Neuron Fly from Slugcat's grasp, becoming passive once it is released.

Directly attacking an Inspector or eating a Neuron Fly within their line of sight makes them aggressive for the rest of the cycle.

  • Inspectors turn red when in close proximity to Rot, but this is independent of their emotional state, as they can fade back to normal even when the Rot is within their line of sight.
An Inspector exploding on death
  • When pulled by an intense force or stunned (notably through Artificer's deflect), Inspectors briefly shift to a red color that is more vibrant than their enraged state.
  • Explosive Spears are effective against Inspectors because most of their damage is not immediate.
  • On death, Inspectors explode and disappear save for their eyes. This is a trait shared with Overseers.
    • Inspector Eyes have the highest trading value in the game, worth twice as much as Pearls.
  • Inspectors share colorations with their respective Iterator's overseers.
  • Certain Inspector spawns in Five Pebbles are replaced by Daddy Long Legs in later campaigns.
  • Inspectors use the Daddy Long Legs creature template, so most creatures are afraid of them.
    • Inspectors are set to have the default relationship of "Uncomfortable with", but this gets overwritten by the Daddy Long Legs' creature relationships.
  • Inspectors do not immediately lose aggression towards a creature upon their death and continue to attack until they calm down.
  • In Arena mode, Inspectors may spawn in orange or green. These colorations likely belong to Seven Red Suns and No Significant Harassment, respectively.
  • One of the names that Inspectors are known by, Axons, are a direct reference to a real part of neurons. Axons are the long, threadlike part of a neuron that transports electrical impulses. However, Inspectors more resemble the cell body of a neuron.
