Fiend

A Fiend is a Xeno caretaker. They run on all fours and are very small. They pounce on the player and attack you.

They are very easy to kill and have energy shields. They have armor like most Xenos.

They hide in walls and can crawl on ceilings. This means they have claws, or gravitational technology that allows them to walk on ceilings and walls.

They feature in N.O.V.A. 1 and 3; in 1 they seem almost parrot like and tend to creep up on you, and burst through ceilings. They tend to run at you in both games. In 3, they seem almost like robot spiders, making clicking sounds. You will often see them running underneath the glass in the Lost Ark, or spilling out through broken vents or small holes.

They announce their presence by a short wailing or clicking sounds. Within those few seconds, they will start to come. They are never alone, and, unlike in the first game, they explode (even if the explosion is rather small) upon death.

History
They were developed by the Judgers first as engineered animals for terraforming and populating and fertilising dead planets. But as the Ark failed they escaped, and overrun the ship.

Trivia

 * They make metallic noises as they walk, a clinking, in N.O.V.A. 3.
 * They resemble in both purpose and structure Grunts from Halo. Their strength relies on large mass attacks and are easy to kill. They also resemble Sentries from Conduit.
 * They are the second weakest enemy in the N.O.V.A series.
 * They almost always are in groups.
 * They can be be destroyed in one Handgun shot in N.O.V.A. 3 at close range.
 * It is currently unknown why they are used by the Xenos for fighting if they were originally meant for terraforming. They may be used to board ships as they seem to execel at navigating and ambushing aboard ships
 * The original model apears similar to the xenomorph from Alien. Also they both are effective at attacking inside a ship.
 * These creatures seem to explode like robots in N.O.V.A. 3
