John-Caleb Bradberton was 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] Bradberton also utilized the Quantum from this formula to create Nuka-Cola Quantum. Unfortunately, because the project was still only in its early stages at the time of the War, only his head was able to be preserved.

In 2287, Bradberton believes his condition to be nothing but torture, 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. Should the Survivor go through with his request, they will find the Quantum nukes in a room behind Bradberton, as well as the formula for Nuka-Cola.

Behind the scenesEdit

50 Vault-Tec C.E.O.The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
  • His name is an amalgamation of the inventors of Coca-Cola (John Pemberton) and Pepsi-Cola (Caleb Bradham).
  • Bradberton's cryogenically preserved head is a reference to the myth that Walt Disney was cryogenically 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 Disneyworld.
  • In Fallout 4, his appearance could also possibly be based on that of the Norse God Mimir, whose severed head was to be tormented with eternal life. Along with this, Mimir offered secret knowledge, much like Bradberton.
