Introduced in the Burning Crusade expansion pack. Floating Eyes are only seen in specific locations, and that is probably a good thing; many adventurers are struck with fear at the sight of such odd and malevolent beings. They resemble an orb of pale green flesh floating in the air, with a toothy mouth, numerous eyes, and a few short tentacles hanging down. The most famous Floating Eye is a boss from the Blood Furnace wing of Hellfire Citadel. Other than that, only a few lesser Eyes have been seen in Netherstorm. Whatever created these abominations is still unknown.

Floating Eyes fairly undoubtedly pay homage to the Beholders from the Dungeons & Dragons universe. Many players who are unfamiliar with the name “Floating Eye” call them Beholders.

Some skeletons are animated through necromancy. Most skeletons are raised from battlefields and thus are often seen still clothed in rotting garments and rusting armor. Some skeletons still fight with the weapons they died clutching. Others, specifically created only by the most advanced necromancers are able to cast magical spells. Whatever they attack with skeletons are basically mindless automatons who are either directly controlled, or made to follow a specific order from their creator. If sufficiently damaged, the magic holding their bones together will dissipate, and they will crumple lifelessly to the ground.

Some skeletons, however, actually seems to possess some kind of intelligence, like Mordresh Fire Eye, found in Razorfen Downs. He can be seen talking to and encouraging his brethren, holding a speech about how the undead Scourge will consume the whole of Kalimdor.

In addition to the skeletons described here, some others may be other types of undead that are simply very old and all their flesh has rotted away, leaving nothing but bones.

Ghouls are the shock troops of the Scourge. These lumbering, rotting corpses were once innocent townsfolk who have made the final transition into true undeath. Ghouls have great stamina and revel in combat with living beings. Ghouls are ravenous cannibals who can replenish their health by devouring the flesh of fallen warriors, friend and foe alike.

During the third war, ghouls were used as basic attack units, and also used to harvest lumber to build scourge structures.

Ghouls are found in several places throughout Azeroth, primarily the Eastern Kingdoms. Most notable are those who terrorize the Plaguelands as the front lines of the Scourge, heavy concentrations can also be found in Eversong Forest and Ghostlands. Mindless ghouls can also be found in Silverpine Forest and Duskwood.

Ghouls have the appearance of a bent, twisted humanoid figure. Much of their flesh has rotted away, exposing a fair amount of bone and twisting facial features until they are unrecognizable as human. As undeath progresses in a victim, it twists and corrupts the body, growing fangs and claws. The ghoul is the final stage of the process of undeath. Despite all this, Ghouls are not particularly intelligent, being mindless monsters with the intelligence of a creature such as an Ogre or Gnoll at best, and understand little aside from hobbling around and tearing apart any foe they see.

Flesh Titans are the most powerful constructs of the Scourge. What little knowledge there is points to the Flesh Titans as being far more intelligent than other constructs and possessing deadly electrical powers. The only known Flesh Titan is Thaddius, a boss in the Naxxramas Instance.

In the first days of the patch 1.11 PTRs, the Flesh Titan Thaddius could be heard howling in pain and begging to be put out of his misery. Judging from this, it would seem that his maker accomplished something extraordinary: creating what could possibly be the first sentient construct on Azeroth.

Flesh Titans are strongly inspired by Frankenstein’s monster.

Flesh Giants would appear to be the next step up from the common Abomination. A horrific combination of flesh and machine, they just recently appeared for the first time in the halls of Naxxramas.
