Dwarf Gekko

Scarabs are small, unmanned machinery that guard important areas for Liquid Ocelot in Metal Gear Solid 4: Guns of the Patriots.

Physical Appearance and Abilities
Scarabs are small, black spheres - about 1/3 as tall as the average man - whith a large, blue "eye" and three organic-looking arms which they use to hop around on. While one or a few are easily defeated, the Scarabs often attack en masse, where they show their true deadly potential. Scanning any areas they are guarding with a beam of light, if they find an intruder, an alarm goes off, causing everyone in the immediate area to converge upon them. Besides rolling into or swiping at their enemies to cause injury, they also are fond of latching onto them and inducing a painful, electric shock with their central eye. What's more is that they explode always explode when they take a certain amount of damage, making it dangerous to have any especially close to you. They also have the ability to latch onto walls and work like a security camera, and if they are too far away to engage in physical combat, they have some sort of internal firearm that they shoot at their enemy with.

Appearances
Three Scarabs first appear in Act 3, posing as a Resistance member by stacking on top of his other and dawning a trenchcoat. They roll away quickly once discovered.

Shadow Moses is stocked full to the brim with them, where they obsessively scan and guard all indoor areas along with several Metal Gear Gekko. It is here that they show how deadly they can truly be.

They make their last appearance in the inner-sanctums of Outer Haven, attacking in three huge waves as Old Snake makes his way towards the ship's server room. When he gets there, Several hidden Scarabs reveal themselves and very nearly overwhelm him before they are de-activated by Naomi Hunter's virus.
