Amos Burton, portrayed by actor Wes Chatham, is a prominent character in The Expanse TV series. Within the show, Amos is the engineer and mechanic aboard the Rocinante, known for his loyalty, combat skills, and complex moral compass. Though an Earther, he keeps his past shrouded in mystery but hints at a difficult upbringing in Baltimore, with connections to sex work and organized crime. Despite his capacity for violence and a sometimes unsettling demeanor, Amos seeks guidance from those he trusts, often deferring to their judgment to navigate moral quandaries.
Chatham brought the character to life between 2015 and 2022, and since then has co-written The Expanse: A Little Death, a sequel graphic novel that launched on Kickstarter in April 2025. He continues to expand his acting career, with roles in Ahsoka as Captain Enoch, The Ice at the Bottom of the World, and Sheriff Country. Chatham's ability to portray complex and physically demanding roles stems from his background, including military service as an aviation firefighter in the U.S. Navy.
