Brubaker is best known for his work as a comic book writer on such titles as Batman, Daredevil, Captain America, Iron Fist, Catwoman, Gotham Central and Uncanny X-Men. In more recent years, he has focused solely on creator-owned titles for Image Comics, such as Fatale, Criminal, Velvet and Kill or Be Killed. In 2016, Brubaker ventured into television, joining the writing staff of the HBO series Westworld.

Jason Aaron grew up in a small town in Alabama. His cousin, Gustav Hasford, who wrote the semi-autobiographical novel The Short-Timers, on which the feature film Full Metal Jacket was based, was a large influence on Aaron. Aaron decided he wanted to write comics as a child, and though his father was skeptical when Aaron informed him of this aspiration, his mother took Aaron to drug stores, where he would purchase books from spinner racks, some of which he still owns today. Aaron's career in comics began in 2001 when he won a Marvel Comics talent search contest with an eight-page Wolverine back-up story script. The story, which was published in Wolverine #175 (June 2002), gave him the opportunity to pitch subsequent ideas to editors. In 2006, Aaron made a blind submission to DC/Vertigo, who published his first major work, the Vietnam War story The Other Side which was nominated for an Eisner Award for Best Miniseries, and which Aaron regards as the "second time" he broke into the industry. Following this, Vertigo asked him to pitch other ideas, which led to the series Scalped, a creator-owned series set on the fictional Prairie Rose Indian Reservation and published by DC/Vertigo. In 2007, Aaron wrote Ripclaw: Pilot Season for Top Cow Productions. Later that year, Marvel editor Axel Alonso, who was impressed by The Other Side and Scalped, hired Aaron to write issues of Wolverine, Black Panther and eventually, an extended run on Ghost Rider that began in April 2008. His continued work on Black Panther also included a tie-in to the company-wide crossover storyline along with a "Secret Invasion" with David Lapham in 2009. In January 2008, he signed an exclusive contract with Marvel, though it would not affect his work on Scalped. Later that July, he wrote the Penguin issue of The Joker's Asylum. After a 4-issue stint on Wolverine in 2007, Aaron returned to the character with the ongoing series Wolverine: Weapon X, launched to coincide with the feature film X-Men Origins: Wolverine. Aaron commented, "With Wolverine: Weapon X we'll be trying to mix things up like that from arc to arc, so the first arc is a typical sort of black ops story but the second arc will jump right into the middle of a completely different genre," In 2010, the series was relaunched once again as simply Wolverine. He followed this with his current run on Thor: God of Thunder.
