Dan Slott has built a loyal fan base by combining old-school fun with stories and characterizations friendly to new readers. Following his run on She-Hulk, Slott moved into the upper echelon of Marvel writers, launching Avengers: The Initiative and taking the reins on Mighty Avengers from Brian Michael Bendis. When Marvel gave Spider-Man a fresh start in 2008, Slott was one of several rotating writers on the thrice-monthly Amazing Spider-Man. Slott became the writer most closely identified with the web-slinger’s “Brand New Day” era, and the title hit the “Big Time” when he took over as full-time writer for a decade-long run. Slott has also turned his talents to other iconic Marvel heroes — including soaring the spaceways with Silver Surfer; helming Tony Stark: Iron Man toward Iron Man 2020; and masterminding the glorious return of Fantastic Four, leading to his long-awaited “Reckoning War.” In 2022, Slott made his way back to the Spider-Verse, teaming with legendary penciler Mark Bagley on Spider-Man.
Following his dynamic and eye-catching work on Marvel UK’s Dark Guard, Spanish artist Carlos Pacheco went on to illustrate Bishop, X-Universe, Starjammers and Excalibur for Marvel before becoming regular penciler on X-Men. He then teamed with Kurt Busiek on the fan-favorite Avengers Forever. Pacheco wrote and drew Fantastic Four, and penned a spinoff Inhumans limted series. His first work upon returning to Marvel in 2009 was Ultimate Comics: Avengers with writer Mark Millar. He subsequently helped relaunch Uncanny X-Men with Kieron Gillen.
Italian-born artist Andrea Di Vito’s work for Marvel Comics includes the limited series Annihilation and Stormbreaker: The Saga of Beta Ray Bill; the one-shot What If Aunt May Had Died Instead of Uncle Ben?; and stints on series such as Captain America and the Falcon, Thing, Thor and Young Avengers. His first published work in the United States was a pinup in Marvel Shadows and Light.
Multitalented Spanish artist Javier Rodriguez is a former graphic designer turned colorist and penciler who has brought his distinctive hues to titles including The Mighty Thor and Doctor Strange: The Oath. Rodriguez has handled both penciling and coloring duties on Amazing Spider-Man. And having helped maintain the impressive artistic standards of Mark Waid’s  Daredevil with his mastery of the palette, grabbed the chance to also wow readers with his line work on the title. He drew and colored the first Superior Spider-Man Annual before bringing his distinctive style to the new-look Spider-Woman.
