Skeleton

Skeletons are the remains of deceased people that can be found all around the Wastes.

Background
Skeletons are the bones of human beings found in various places.

Fallout and Fallout 2
In Fallout and Fallout 2, some skeletons can be looted. During the game over screens, the Vault Dweller and Chosen One's skeletons are seen lying dead in the wasteland.

Fallout 3 and Fallout: New Vegas
In Fallout 3 and Fallout: New Vegas, the player can pick up this object, but not loot it.

Also in Fallout 3 and Fallout: New Vegas, the player may find a skeleton near weapons, ammunition, notes and medical supplies. They may even correlate with unmarked quests.

Skeletons can also stretch out, they will sometimes fling when interacted with, for more information go to Fallout 3 bugs.

In Dead Money, the skeletons of Vera Keyes and Frederick Sinclair can be found in the Executive suites and the Sierra Madre vault, respectively. Vera's skeleton can be dismembered and wears a unique outfit that can be retrieved by the player. Sinclair's skeleton acts as a container, although it contains nothing.

In Honest Hearts, the skeleton of Randall Clark, a.k.a. the Survivalist, can be found atop the Red Gate.

In Old World Blues, Y-17 trauma override harnesses, automated suits that house long deceased test subjects, can be found all over Big MT. Additionally, the skeleton of Dr. Calis can be found clothed in Scientist scrubs, however, you can search this skeleton. You can also see that no spinal cord connects with the rest of the body; this is because the game says he is wearing a "hat".

Fallout 4
Skeletons can be found all across the Commonwealth, ranging from the remains of U.S. Army soldiers to citizens, and even Vault Dwellers. Unlike their counterparts from Fallout 3, they cannot be picked up.

Appearances
Skeletons appear in all Fallout games.
