Hoby Buppert was a 20 year-old college graduate who was looking for an alternative to coffee in 1997 as part of a class project. He came up with a carbonated and non-alcoholic beverage made from guarana, a naturally caffeinated berry native to the Amazonian rainforest.
Looking for a place to settle, he chose Texas, a quiet place, conducive to the growth of guarana. The company markets its drinks only in Texas forever, never looking to emigrate because of the market leader, Nuka-Cola. But before the Great War, Bawls Guarana concluded a lucrative contract with Vault-Tec, which wanted to build the Secret Vault in Texas. They sponsored the construction and only its product was allowed in the vault, at the expense of Nuka-Cola, which was virtually non-existent in the region.
Hoby Buppert is mentioned only in Fallout: Brotherhood of Steel.
