Kellogg

Kellogg is an antagonist appearing in Fallout 4.

Background
Kellogg is originally from the New California Republic on the West Coast. As a child, his mother couldn't depend on his father to feed the family and relied on Kellogg instead. Eventually, Kellogg moved to San Francisco where he married and had a daughter, Mary. He fell into trouble again, the consequence being the death of his family. Despite the harsh punishment, Kellogg still cared for children, but moved on.

After working as a mercenary in the west, Kellogg traveled to the East Coast and the Commonwealth, where the Institute hired him to find Vault 111; the Institute required radiation-free test subjects, and the vault's cryogenically-preserved residents were the perfect candidates. Kellogg chose Shaun, and killed Nate/Nora when they resisted. Shaun's DNA was used by the Institute to complete the Generation 3 synths, and he eventually became the Institute's director.

At some point, Kellogg was cybernetically enhanced, presumably by the Institute, which halted his aging and extended his lifespan. By 2287, he is over 100 years old, but physically appears to be less than half of that.

Some time after kidnapping Shaun (according to Ellie Perkins, this was when Shaun was around 10), the pair lived for a while in Diamond City where Kellogg enjoyed his cigars and liquor, but he eventually abandoned their house after X6-88 came to collect Shaun on behalf of the Institute. Afterwards, the Institute continued to rely on Kellogg's services for other odd jobs they needed done in the Commonwealth.

He later barricaded himself in Fort Hagen where he was finally confronted in the quest Reunions. On his way from Diamond City he hurt himself in several battles, making it easy for Dogmeat to scent his trail.
