The Outsider is the Protagonist of Fallout: Eleventy.
The Outsider was once a mercenary for Talon Company, until he was discharged for abandoning his team during a super mutant ambush. He was later found by Brotherhood Inquisitors and captured. Due to his military background, and status as a POW, he was deemed expendable and therefore sent to the UK.
When the vertibird The Outsider is on is shot down his companions are all killed. After wandering around for some time, The Outsider eventually stumbles upon a heated conflict between Spoonfield Mercenaries and Wolf Hybrids. Eventually choosing a side in the conflict, the victor spirits the Outsider to their respective leader.
