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.

James P. "Jim" Starlin is an American comic book writer and artist. With a career dating back to the early 1970s, he is best known for "cosmic" tales and space opera; for revamping the Marvel Comics characters Captain Marvel and Adam Warlock; and for creating or co-creating the Marvel characters Thanos and Shang-Chi, Master of Kung Fu. Death and suicide are recurring themes in Starlin's work: Personifications of Death appeared in his Captain Marvel series and in a fill-in story for Ghost Rider; Warlock commits suicide by killing his future self; and suicide is a theme in a story he plotted and drew for The Rampaging Hulk magazine. In the mid-1970s, Starlin contributed a cache of stories to the independently published science-fiction anthology Star Reach. Here he developed his ideas of God, death, and infinity, free of the restrictions of mainstream comics publishers' self-censorship arm, the Comics Code Authority. Starlin also drew "The Secret of Skull River", inked by frequent collaborator Al Milgrom, for Savage Tales #5 (July 1974). When Marvel Comics wished to use the name of Captain Marvel for a new, different character,[citation needed] Starlin was given the rare opportunity to produce a one-shot story in which to kill off a main character. The Death of Captain Marvel became the first graphic novel published by the company itself. ( In the late 1980s, Starlin began working more for DC Comics, writing a number of Batman stories, including the four-issue miniseries Batman: The Cult (Aug.-Nov. 1988), and the storyline "Batman: A Death in the Family", in Batman #426-429 (Dec. 1988 – Jan. 1989), in which Jason Todd, the second of Batman's Robin sidekicks, was killed. The death was decided by fans, as DC Comics set up a hotline for readers to vote on as to whether or not Jason Todd should survive a potentially fatal situation. For DC he created Hardcore Station.
