The new Ultimate Comics Spider-Man illustrator has signed a contract with the top publisher, it was announced at San Diego Comic-Con International.
"Marvel approached me with the offer to go exclusive shortly after I began my run on Ultimate Comics Spider-Man and I really didn't need too much convincing," Marquez told Comic Book Resources.
"I'd been a Marvel fan long before I ever began working for them and it was a huge honour just to be asked. Naturally, we spent a little while hashing over the details and fine print, but in the end the opportunity to continue working on these characters, and teaming up with some of the best talent in the industry was something I had to pursue.
"And, on a practical note, exclusivity offers a kind of stability not often afforded to freelancers. At this point in my career, that stability is incredibly valuable."
Marquez worked as an animator on A Scanner Darkly after graduating with a degree in history and government from the University of Texas.
He also has a forthcoming, creator-owned title The Joyners in 3D, which will be published by Archaia.
Will Conrad recently ended his exclusive contract with Marvel, moving to DC Comics to pencil Stormwatch.
There has been a focus on creator-owned versus work-for-hire and contracted employment lately, with top creators including Ed Brubaker ending long runs for the 'Big Two' publishers to focus on their own titles.
