Ed (Fallout)

Ed is a skeleton in a vault suit which lies just outside the Vault 13 doors. He was the first person sent outside the Vault, before the water chip got broken, and was probably killed by mutant rats.

Behind the scenes
Ed was of course a reference to the Pulp Fiction line Zed is dead. Here's a quote about Ed by Chris Taylor:
 * What's the deal with Ed? Zed's Dead, baby, Zed's dead. From Pulp Fiction. That's part of the reference. Ed was twofold: to immediately show the player that the outside world was dangerous, and to tell the player that he wasn't the first choice of someone to send out. Ed was sent out before the waterchip malfunction, however, since he's just bones.
