Boney

A Boney, (also known as Living Dead by UAC researchers) is a class of Zombie found in Doom 3. They are naked, partially decayed zombies who emit guttural growls and moans, while slowly shambling towards the player to claw him. In the original game, they are featured only in Hell. But in the BFG Edition, they are only exclusive in Doom 3: Resurrection of Evil and Doom 3: The Lost Mission.

UAC Research Notes
These notes can be downloaded to the player's PDA during the course of the game:

Specimen 42 - Living Dead (partial)

''Able to function without recognizable brain activity, this creature has little regard for self-preservation. Though slow moving, its behavior is aggressive and tenacious.''

Behind the scenes
The encounters with hellish Bonies are removed in Doom 3 BFG Edition in Doom 3 but they still appear in The Lost Mission and Resurrection of Evil. Questionably, in the original game, Boney Zombies appear to have scars and look more burnt on their skin in Hell like the Imps and Hell Knights. But in the Hell level of the Lost Mission, their skin looks a lot more normal.

Enemies similar to Bonies appear in DOOM and Doom Eternal in Hell.
