Kellogg

Kellogg is an antagonist appearing in Fallout 4.

Background
Kellogg is originally from the New California Republic on the West Coast. As Kellogg was a child, his mother couldn't depend on his father and let Kellogg know he will feed the family. Eventually, Kellogg moved to San Francisco where he married and had a daughter, Mary. He fell into trouble again and was punished by having his family killed. 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, Kellogg lived for a while in Diamond City where he enjoyed his cigars and liquor, but he eventually abandoned his house.

He later barricades himself in Fort Hagen where he is finally is 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.
