15-year comics veteran Axel Alonso has been named editor-in-chief at Marvel Comics, replacing Joe Quesada, who remains at his existing title of chief creative officer. In addition, Tom Brevoort has been named senior v-p publishing. In his new role, Alonso will report to publisher Dan Buckley and oversee all day to day aspects of Marvel's publishing division.

Alonso joined Marvel in 2000 after a stint at DC's Vertigo imprint, where he developed the acclaimed series 100 Bullets. His Marvel duties include running both the Spider-Man and X-men franchises, as well as newsmaking titles like X-Statix and The Rawhide Kid, which introduced a gay gunslinger to the Marvel Universe.

“Marvel has a great history of the most dynamic and memorable EiCs in comics history and I’m honored to step into this role,” said Alonso. “I’ve been blessed to work with some of the most creative men and women in the world, bringing to life some of the most compelling stories you’ll find in any medium. This new role provides me with exciting challenges and prospects I’ve never encountered before, but I know one thing—Marvel’s getting even bigger in 2011.”

Quesada, who held the e-i-c title for 10 years, will move on to work more on Marvel's burgeoning multi-media projects in films, television and internet. Marvel was acquired by Disney for $4 billion in 2010.
