John-Caleb Bradberton is the founder of the Nuka-Cola Corporation, and the inventor of Nuka-Cola.


John-Caleb Bradberton invented Nuka-Cola in 2044, becoming a powerful man and CEO of the Nuka-Cola Corporation. Over the years, he spent much of his time trying to acquire the rights to various other soft drink brands, and changing them to fit the corporation.[1]

In the years before the Great War, Bradberton was given access to the LEAP-X Program by General Braxton, as part of "Project Cobalt," in exchange for his weapon designs: an enhanced version of the Fat Man which would fire Quantum nukes,[2] in which Bradberton also utilized the Quantum from this formula to create Nuka-Cola Quantum. Thanks to the LEAP-X Program’s technology, Bradberton’s life was vastly prolonged, but due to the program’s infancy at the time of the War, only his head was able to be preserved.

By 2287, Bradberton regrets participating in the LEAP-X Program, considering his condition to be nothing but a "living hell" after two centuries of isolation,[3] and wants nothing more than death. He offers the Sole Survivor prototypes of his weapons if they choose to kill him by shutting off his life-support system. Should the Sole Survivor go through with his request, they will find a collection of Nuka-nukes in a room behind Bradberton, as well as the formula for Nuka-Cola.

Interactions with the player characterEdit


Cappy in a Haystack – John-Caleb Bradberton wishes to be put out of his misery, by having the power to his cryogenic preservation shut off, while Sierra Petrovita wishes to keep him alive.

Effects of player's actionsEdit

  • If his life support machine is switched off, his eyes will remain open and periodically move as if he's still alive.
  • If the player accepts Sierra's offer and then shuts down Bradberton's life support machine, Sierra will condemn the Sole Survivor for their actions, furious for taking advantage of her, and then turns hostile. Should this happen, there are only 2 ways to proceed: kill Sierra or escape the bunker.


An additional character render for Bradberton is found within the game's files, with the base id xx044d61. If spawned using the console, a silent NPC wearing wildman rags will appear. This render matches the one found in the game's files for General Braxton.


John-Caleb Bradberton is mentioned in Fallout 3 and appears only in the Fallout 4 add-on Nuka-World. He is also mentioned in the Fallout 76 add-on Wild Appalachia.[4]

Behind the scenesEdit

  • His name is a portmanteau of the names of the inventors of Coca-Cola (John Pemberton) and Pepsi-Cola (Caleb Bradham).
  • Bradberton's cryonically-preserved head is a reference to the myth that Walt Disney was cryonically frozen after his death; as the inventor of Nuka-Cola and head of the Nuka-Cola Corporation, he is to Nuka-World what Disney was to Disneyland and Walt Disney World.
