Flayed Ones

He almost looks cute and that pleases Him

"Craaawling in my skin.. These wounds, they will not heeaal..."

"To those who have turned their faces away. To those who are faithless and wretched in their jealousies. To those who have denied us. To those who have denied me. I will wreak vengeance. I will wrench your souls and break your bones. I will cast hunger through your accursed existence. Down the eons, you will not forget. I will grant you this gift from love turned aside and make you like me, break you in my image as you have broken me. I shall cast the fear of myself into you and all of your kind. I am Llandu’gor. I am the hunger. I am the flayer, and from this moment, you shall be too."
--The Curse of Llandu'gor the Flayer

Flayed Ones are Necrons who go about wearing the bloody flesh of their victims. They are victims of the Flayer virus, a program error where they develop a desire to reclaim their flesh and blood existence by devouring the flesh of the living (And since they don't have any kind of digestive system, the eaten flesh just falls down through their ribcages)
It's the end result of the C'Tan known as Llandu'gor the Flayer, who was not sharded like the others, but completely destroyed. Still, he had enough warning to curse the Necrons who killed him to suffer the Flayer virus as a last "fuck you;" they spread the virus to others, who spread it still further, and so on for quite some time until the other Necrons caught on.

Flayed Ones are basically the Lepers of Necron society, feared and ostracized for their disease. Although instead of sending them to a Leper colony, the Necrons simply try to kill them to prevent the spread of infection before it fully emerges (that's disease control in Warhammer 40,000 for you); the ones that don't die end up in a weird subspace dimension where they hang out with other Flayed Ones until they sense bloody battle, at which time they warp out, kill everything with a pulse, and warp back there again once they're done. The "clean" Necrons don't mind this so much as long as the Flayed Ones fuck off as soon as the battle is up.

This new lore comes from the Fifth Edition Necron Codex. In Third Edition, Flayed Ones were just close-combat specialists who liked to play dress-up with the skins of their slain foes. The reason for this, just before the release of the 5th edition codex, was the Flayed Ones were Necrons who retained their emotions and went insane. The causes were either being AWAKE, IMMOBILE AND ALONE during the 60 million year long great sleep or that they wanted to reclaim their old bodies and that was their warped way of doing it. Unfortunately, their models and their lore were not updated well -- they went from "pray we kill you before we flay you" to "dance party."

The Bone Kingdom of Drazak

A nice piece of story from the 5th Edition Necron Codex tells of a legendary Tomb World named Drazak (located in the Ghoul Stars) or alternatively the Bone Kingdom. It's a world populated almost entirely by Flayed Ones, who are ruled by Valgul the Fallen, a Necron Lord who is immune to the Flayer virus. The world is devoid of living creatures, so the Flayed ones roam around fighting each other for scraps of rotten meat and bone. Every few months Valgul rises from his throne of bone and announces a Time of Bounty, where they launch fleets to raid nearby planets to collect flesh and blood of the living to sate his subject's hunger. Which leaves the questions a) Why anyone would stay on those nearby planets, b) Why nobody has performed Exterminatus upon Drazak yet and c) Why the Flayed Ones return to Drazak instead of crusading across the stars.
All three questions are answered by one word: Grimdark.

"I'm gonna show you the world, Herbert. Thank you for your face, by the way."

Flayed one from the 6th ed. 'cron codex

They used to mostly suck. They were, and still are, Elites (one of the most competitive slots in the Necron army), they have one of the few 4+ armor saves in an army of MEQs, they could only do close combat but only have Initiative 2, they can't take transports, and they couldn't score, though they can now, thanks to 7th Edition! What they could achieve was based on their cheap price (same price as Necron Warriors), large squad size and their ability to Deep Strike and Infiltrate; basically, you fielded them along with Warriors and Scarab Swarms if you wanted to play Necrons horde-style...

But never again will the Flayed Ones be one of the prime examples of bad design - the 7th Edition Codex is arriving, and it heralds a new time for our favourite robot lepers. While their statline remain unchanged, they now count as having two seperate melee weapons, which give them 6 Attacks instead of 3.(Since when the fuck does having 2 melee weapons give double the attacks? You get +1 attacks like everyone else.) This of course is pretty good, since their point cost are unchanged... But it doesn't stop there. Oh no. Not only were the Flayer Claws made seperate weapons, they gained Shred and AP 5 as well. Fuck yes. Throw ten Flayed Ones into some Guardsmen and unleash 60 40 Bolter hits with Shred (mmmm guardsmen my favorite). Remind your opponent to bring a handbroom to remove his mutilated hordes easily.

Maynarkh Dynasty/"Dark Harvest" supplement from Imperial Armor also fixed most of their problems their own way. They can be Troops so as not to fight for an Elites slot, being Troops gain Objective Secured, and they can buy Flensing Scarabs to reroll failed to-wound rolls for a turn.

8th edition

They're okay. They're still an elites choice (and cost almost as much per model as Praetorians) but with their deep strike and +1 to morale tests for nearby enemy units they can be very useful for probing the enemy back lines. Unfortunately with the deep strike rules they're gonna need a 9" charge to get into combat on the same turn they deep strike and have only melee attacks, but if they do get into combat they can seriously fuck up MEQ and below. A full squad of FO can deal out a face-melting 40 attacks per turn the reroll wounds. Take them with Anrakyr to deal out 50 attacks and watch your opponent cry as you delete his units. Still relying on making that 9" charge though (although you can reduce it to 8" if you use Anrakyr's MWBD on the flayed ones, also meaning you'll get 50 attacks hitting on 2s).
