Writer and editor Fabian Nicieza has been in high demand since the mid-1980s, with some incredible credits that include co-creating Deadpool and X-Force, and writing for Marvel titles like New Warriors, X-Men, and Cable.

Nicieza was born on December 31, 1961 in Buenos Aires, Argentina, then his family moved to the US when he was 4 years old where he learned to read and write from comics. He studied at Rutgers University where he earned a degree in advertising and public relations.

In 1985, he joined Marvel as a manufacturing assistant then moved on to being an advertising manager. While working in those jobs he started writing articles for the Marvel Age magazine.

His first published comic story was in Psi-Force #9 under Marvel’s New Universe imprint, becoming the regular writer at issue 16 until the last issue, issue 32. Once Tom DeFalco created the New Warriors team, he gave Nicieza the writing assignment. He wrote the first 53 issues of New Warriors from July 1990 to November ’94, and during this period he also wrote for Alpha Flight, Avengers, and Adventures of Captain America.

In ’91 Nicieza started working with Rob Liefeld on New Mutants, co-creating Deadpool, Shatterstar, and X-Force. They continued collaborating on the X-Force title with Nicieza initially as the scripter, then he became the full writer with issue 12 through ’95. At the end of ’92 he became a regular scripter for X-Men at issue 12 and was one of the writers/editors who handled the crossover events like “X-Cutioner’s Song” and “Age of Apocalypse.”

In addition to juggling those titles, he also wrote the first Cable miniseries and the first few issues of the ongoing series. He also wrote Deadpool: The Circle Chase, the first solo Deadpool series.

After a dispute with then editor-in-chief Bob Harras, he left the X-Force and X-Men titles. In ’95 he wrote short runs of Captain Marvel and Spider-Man: The Final Adventure, then a year later he did his first work for DC, co-writing Justice League: A Midsummer’s Nightmare with Mark Waid.

Later in ’96 he joined Acclaim Comics as the senior vice president and editor-in-chief to revamp intellectual properties from Valiant like X-O Manowar and Ninjak. He started doing freelance work for Marvel on the “Magneto Wars” crossover in Uncanny X-Men and X-Men. Nicieza followed it up by writing Thunderbolts #34-75.

His early 2000s work included limited series at Marvel and DC, including X-Men Forever, Hawkeye, Supermen of America, and JLA: Created Equal. In 2003 he co-created The Blackburne Covenant horror miniseries with Stefano Raffaele for Dark Horse then wrote all 50 issues of Cable & Deadpool. Back at DC, he wrote issues of Action Comics, and worked on Nightwing and Red Robin.
