It's been all right, you know? The apocalypse and all. I know that seems weird but... I have freedom now. I can actually help people... I even met somebody, a volunteer who delivers supplies. Imagine that, right? Even when you think everything is over, it's... it's not.Survivor story: Miguel Caldera

Miguel Caldera is a deceased member of the Responders in Appalachia.


Prior to the Great War, Miguel was a programmer working for Vault-Tec. Burdened by soul-crushing office programming jobs, he longed for nothing more than to live in the country and focus on hiking.[1] He also previously worked for the United States Space Administration, where he wrote the encryption algorithm for the Deep Sleep project's flight recorder as well as the Arachne killswitch program for the project's mainframe AI, ATHENA[2][3]

After the bombs fell, he survived for several years alone in the wilderness, camping in the woods with a Protectron which he had hacked to guard him as he slept.[1] He met Dassa Ben-Ami one day when she was hunting for rabbits and agreed to join the Responders,[4] acing their survival training programs.[5] His main reasons for doing so were his fear of scorchbeasts and his desire to no longer live alone.[6] As a programmer, he became a boon for the Responders, becoming responsible for training volunteers and developing programs for robots and automated kiosks to take over tasks, in addition to reprogramming robots to fulfill roles needed by the Responders' operations. He also helped train others in outdoors survival, leaning on the experience he had gained since the War.[7]

His first major personal achievement was the creation of Mr. Fluffy, a Protectron bodyguard and assistant. The robot, stitched together from countless damaged Protectrons, had an attitude problem and was none too pleased by its name (metallic surfaces are by definition not fluffy, and the failure to compute aggravated Fluffy's neural network).[8]

One day, during a supply run between Morgantown Airport and Flatwoods, he met a volunteer responsible for delivering supplies named Garry Wilkins, and they fell in love.[1][9] As Garry was stationed at the Flatwoods outpost at the time, Miguel often made excuses to spend time there, including by programming elaborate systems which needed his attention.[4] They eventually transferred to Morgantown Airport, where Miguel turned his attention to leading advanced survival training classes, as well as continuing his engineering and programming duties. At the same time, he was developing a reset program to make Mr. Fluffy less unconventional, including stopping him from staying at his side all the time, which he believed to be ruining his sex life.[10]

After Garry was killed during a Scorched attack on the airport, Miguel retreated to the woods after burying him in the Responder graveyard nearby. He took Mr. Fluffy with him and left Maria Chavez a message to tell her where he had gone, saying that he had to "figure things out."[11] His last check in with the Responders was at Morgantown Airport on 15 June 2096.[12]

By the time the Vault Dweller finds him, he lies dead in his camp near the airport, next to his destroyed tent. Mr. Fluffy questions his body as to why he didn't follow his own advice about building defenses and why he decided to cook Appalachili, with an aroma that the robot states could be detected clear from the airport tarmac. This was a deliberate decision, mirroring the way that he claimed he wanted to die - not in an office, but with "a pot of Delbert's chili, in the woods, and under the beautiful stars."[13]
