Atrax Wraith

"They were built in case something went wrong within the universe, but making thses things made the situation worse, it seems..."

- Matoran Parelis to Toa Vulzaria

History
The Atrax Wraiths were created by the Great Beings as a failsafe for the Matoran Universe, in case they couldn't shut the robot down. The wraith's objective was to make any living being or creature in the universe dissapear, and once, or if ever their job was completed, they would dissapear aswell. They were placed within spheres somewhere near the Bohrok nests.

After the Toa Mata defeated Teridax in Mangaia, the Makuta launched the signal used to awaken the Bohrok, but not known to anyone, the signal was also designed to awaken the Atrax Wraiths aswell, and they proceeded to the island's surface.

They began to devour the Matoran there, but once they discovered the other parts of the Matoran Universe had to be cleaned of all life, they moved from Mata Nui to the other islands, with only one being left on Mata Nui.

The wraiths split up, and a vast majority took refuge on one of the Southern Islands, devouring any being or creature that came across the area. During this time, they began to develop personalities and emotions.

One of the wraiths was captured by the Order of Mata Nui, and was taken into study. Soon after realizing that the wraith had emotions and a personality, it was recruited into the Order, and christened 'Orzeni', the Matoran word for 'Ghost'.

Another wraith came acros the island of Nynrah, and started devouring the inhabitants one by one. The Nynrah Ghosts, now aware of the warith's presence, designed a weapon and a cage specifically made to imprison Atrax Wraiths. The warith was captured, and imprisoned. It was sold to the Brotherhood of Makuta, who then passed it on to the Dark Hunters. During a fight between the Dark Hunter's Relic and Outlaw, the cage was opened, and proceeded to kill Outlaw. The Shadowed One then persuaded the wraith to join them, and it accepted, coincidentally named 'Wraith' by the Dark Hunters.

Two more haunted Voya Nui, and three others picked off the Matoran on Mahri Nui. However, the Pit Mutagen locked one of them in its solid form, and it developed some other physical mutations aswell. All the wraiths apart from the mutated one migrated to the Southern Continent after Mahri Nui was destroyed and Voya Nui returned to the Continent. The mutated wraith then stalked the Toa Mahri, and followed Matoro until he reached Karda Nui. It managed to escape being blinded by the flash of light unleashed by the Ignika. It then travelled to an Av-Matoran village, but upon reading Av-Matoran Solek's mind, he realized that the Av-Matoan were needed to create more Bohrok shells, and left them in piece. The wraith, beginning to starve, began hunting the Rahi in the swamp of secrets. When the Energy Storms errupted, the wraith hit inside the Codrex. It's current status is unknown.

When Teridax died and the Matoran Universe was disabled, the wraiths migrated to Spherus Magna, and began to terrorise the inhabitants there, with them believing it is a disease.

Abilities & Traits
The Atrax Wraiths have a unique feeding system, in which they turn invisible to avoid being seen, and go inside the intended victim, slowly feeding off their memories, their throughts, they personality, and thei very essence, until the victim is non-existant. Some who have had a wraith feeding on them have avoided being completely devoured, with some having living bodies, with no mind or spirit, and some having no body, but still possess a mind and spirit.

The wraiths have since developed personailities, with only a few helping the inhabitants, and the vast majority following their programming. They do not hesitate while taking action, and all are cold, cunning and sneaky.

Their physical appearance is having white spiked armour, verying eye colours, clawed hands, and a tail in which they use to crawl when they can't use their levitation power. One mutated wraith has more spikes on its armour than usual. All Atrax Wraiths are amphibious.

They posses a variety of powers, such as intangibility, telepathy, and their unique feeding ability.
