Corpse

A corpse is an inanimate, dead body. Corpses of dead player characters turn to bones after they resurrect. Corpses of mobs remain for a time, but eventually decay and disappear. If materials are gathered from a corpse with Skinning, Engineering, Mining or Herbalism, the corpse disappears after looting the leather, hides, metal, ores or herbs.

On the mini map or world map, a gravestone/tombstone will show the location of your corpse. On the outer ring of the mini map, a red indicator arrow will point the way to your corpse if it is not visible on the mini map.

As items, objects or NPCs
In WoW there are specific corpses that act as interactable items, objects or NPCs usually during quests.

While most corpses appeared as normal undamaged models or as big stacks of unidentifiable meat, a unique model of dwarven corpse existed and was used on multiple occasions, such as with Henrig Lonebrow, A Dwarven Corpse, Ebenezer Rustlocke's Corpse, Battered Dwarven Skeleton, and Featherbeard's Remains.

Death knight ability interactions
Death knight players used to have a Corpse Explosion ability. The Raise Dead ability used to require a corpse or Corpse Dust.

In Warcraft I
The Dead are raised from dead bodies by Necrolytes using the Raise Dead spell on them.

In Warcraft II
Death Knights can animate corpses of the newly dead into Skeletons.

In Warcraft III
Skeleton Warriors and Skeletal Mages can be summoned by Necromancers from dead corpses. Rod of Necromancy creates two Skeleton Warriors from a corpse.

Meat Wagons can carry corpses. Graveyards produce corpses next to the building.

Cannibalize can be used by Ghouls and Abominations to consume a nearby corpse and restore health.

Structures and landmarks
There are large areas that are landmarked by corpses of large creatures, such as: Master's Glaive, Kodo Graveyard, Pools of Aggonar, Dragonblight and Xibala.

Corpses of colossals from Draenor are (or have been) used for structures, including Temples of the Damned that were built during the Second War.
