Shaun, also known as Father, is the son of the Sole Survivor and the leader of the Institute in 2287. He serves as the primary antagonist of Fallout 4 unless the player character chooses to side with him.



Shaun was born in 2077. He lived with his mother and father in Sanctuary until in October 23, the Great War broke out. His father and mother fled with him to the nearby Vault 111 where they expected to endure the war. However, once inside the vault the inhabitants were frozen in cryo-chambers. Approximately six months following their internment, a revolt occurred and the staff abandoned Vault 111, leaving those frozen within unaware of what had occurred.

150 years later, the Institute found the location of Vault 111. Desperately searching for genetic material unaffected by the radiation-ravaged wasteland for their Third Generation Synth project, the Institute were thrilled when they found out that the Vault housed an infant who never came into contact with the radiation. Conrad Kellogg was sent to the vault to retrieve Shaun. Kellogg opened the chamber in which Shaun and one of his parents (the spouse of the main protagonist) awakened from their sleep. As the parent was unwilling to yield Shaun to the Institute, Kellogg shot him/her and refroze the other cryo-chambers. He then returned to the Institute with Shaun.

Shaun was then raised by the Institute as one of their own, His DNA was used to complete the synths, gaining him the nickname Father. During his youth, Shaun showed great potential and eventually became one of the lead scientists of the Institute.

Leader of the Institute

Eventually, Shaun became director of the Institute. He became interested in his surviving parent who, believing that Shaun was still a small boy, searched the Commonwealth for him. Although Shaun did never really know his deceased parent and thus felt no grief for him/her, he allowed the Sole Survivor a way of revenge by delivering Kellogg to him. Kellogg's brain implants also gave the Sole Survivor a way to infiltrate the Institute.When the Sole Survivor find Shaun,He is an old man,who is working for The Institute.


There are many endings that will involve Shaun and the Institute.



  • Shaun's likeness is always based on how his father and mother look like.
  • Shaun can also be killed right after meeting him; though doing so will lock one out from the Institute storyline and make them permanently hostile.
