Gary (clone)

Gary was an inhabitant of Vault 108 and clones of him are the only people left in the Vault

Background
A holotape labeled cloning log can be found in Vault 108, which explains that Gary was cloned at least 54 times. All clones exhibited hostility towards the scientists who created them, with each successive clone being more and more violent but did not show hostility to each other. When the scientists started running out of room to store the clones, they planned to destroy some of them to make room for additional test subjects.

The clones subsequently took control of the vault and when the Lone Wanderer arrives, 13 Garys remain inside, one of which is deceased. Two Garys are mentioned only and another is found deceased in the Outcast outpost, murdered by the Brotherhood Outcasts.

Appearances
Gary clones appear in Fallout 3.

Behind the scenes
The Gary clones are referenced in Fallout 4 as a running gag, where four wooden blocks can be found in assorted locations spelling out "GARY." Another collection of "GARY" blocks are found in the Whitespring Resort in Fallout 76.
