Arthur Maxson

Elder Arthur Maxson is the last descendant of the Roger Maxson, founder of the Brotherhood of Steel. He served as a squire in the Citadel in Fallout 3 and commands the Brotherhood

Background
He was born in 2267 to Lady Jessica Maxson and a high ranking paladin, Jonathan. His father was killed in battle outside the New California Republic, and his mother sent an infant Arthur east to be raised by Elder Owyn Lyons due to an unsafe environment caused by internal conflicts.

Arthur was an attentive student that studied the Brotherhood's history. He observed behemoth from the Citadel walls and quoted the Codex when meeting outsiders. He was trained in combat by Sentinel Sarah Lyons, who on one occasion showed him how to kill people by stabbing them in the kidneys. He was barred from patrols due to accidentally shooting Lyons during an outing and Elder Lyons ordered Maxson be restricted from the Bailey while live fire practice was in effect. During his free time at the Citadel, he wished to befriend Liberty Prime and snuck into Paladin Vargas room to read their copy of Guns and Bullets since he wouldn't give it to him otherwise.

At the age of 12, he killed two raiders on a training patrol, saving the squad that was supposed to escort him. At 13, he killed a deathclaw and received a scar on his face. He killed the super mutant leader named Shephard at the age of 15, who was trying to reorganize the remnants of the Capital Wasteland super mutant infestation.

At the age of 16, he brokered a peace with the Brotherhood Outcasts, re-integrating them into the Brotherhood of Steel. Maxson was subsequently appointed elder, the youngest in Brotherhood of Steel history, and now leads the Brotherhood's forces from the Prydwen. Proctor Quinlan maintains the records of Maxson's history, and notes that he is "assisted, even enhanced, by advanced technology" but is "still very much human."

Appearances
Arthur Maxson appears in Fallout 3, Fallout 4, Fallout: Wasteland Warfare, and Fallout Shelter Online.

Behind the scenes
The T-60 power armor Maxson wears during Airship Down is the only suit that can be found already upgraded to the highest tier (F), and has a unique paint job. If one decides to recolor the armor parts after acquiring them, they cannot be reverted back. It can be added to their inventory with console command.
