Adam Kubert (born October 6, 1959 in Boonton, New Jersey) is an American comic book artist whose work has been published by Marvel Comics, Dark Horse Comics and DC Comics, among others. He is the son of Joe Kubert and brother of Andy Kubert, both comic book artists as well.

Adam Kubert graduated from the Rochester Institute of Technology with a degree in medical illustration. He also attended the Joe Kubert School of Cartoon and Graphic Art in Dover, New Jersey. He has since established himself as one of the leading artists in comics and Wizard magazine recently rated him as one of the "Hot 10 Writers and Artists" in the industry.

Adam Kubert has publicly expressed admiration for the works of Frank Miller, Will Eisner, Jim Steranko, Alex Toth and his father Joe Kubert. Much of the inspiration for Kubert's 'painted' work, as seen on the covers of his Action Comics run, are drawn from the works of Will Eisner as can be seen by the brown almost 'sepia' like finishes with the white highlights. The definitive Wolverine and Sabretooth battle (Wolverine, Vol. 1, Issue 90) featured multiple gatefold interior pages, a throwback to Steranko's work on the 'Nick Fury: Agent of Shield' comic.

He is probably best-known for his work at Marvel Comics, in particular for a sporadic run on the solo Wolverine title with writer Larry Hama, a short run with writer Peter David on the Incredible Hulk and numerous stints on various X-Men titles.

Adam Kubert is noted for his raw, dynamic art style, combined with fluid storytelling and noteworthy pacing. He's also known for his experimentation in art style and storytelling, being one of the first mainstream (i.e. Marvel or DC employed) comic book artist to experiment with the pencils-straight-to-colour approach with Steve Bucellato on The Incredible Hulk.

On his X-Men run, Kubert was teamed up with European colorist Richard Isanove, who subsequently followed Adam to the Ultimate X-Men project, perfecting the pencils-to-color approach seen on most of Ultimate X-Men covers. Kubert has been criticized not meeting monthly deadlines on certain issues, which often required hiring fill-in artists, a penchant that Kubert himself has admitted to having. In a 1998 Wizard interview with Jim McClaughlin, Kubert apologized to fans for the slow output, explaining that readers and fans now expect more of illustrators, and that the onus rests on the artist to spend time creating more detailed and well-drafted illustrations.

Although Kubert remains a talented penciller, the choice of inker for his work greatly influences the quality of the final printed page. It has been argued by fans and critics alike through various mediums such as the internet and comic publications, that some of Kubert's finest work has been embellished by the British inker Mark Farmer, especially his runs on Wolverine and The Incredible Hulk for Marvel Comics. While talented inkers, notably Danny Miki and John Dell, lent their talents to Kubert's pencils during his runs on Ultimate X-Men and Ultimate Fantastic Four respectively, reaction to the final artwork was mixed due to the stylistic nature of the inkers which did not lend itself well to Kubert's normally lush drawings, leading to increasing calls that Adam Kubert should once again be paired up with Mark Farmer, even more so now that Kubert has moved to DC Comics as of 2006.

When Marvel Comics launched the industry-changing Ultimate Universe series in 2001, Kubert was chosen as the penciller for the second launch book Ultimate X-Men. His storytelling and distinct style coupled with writer Mark Millar's well crafted tales, made the book an instant success. Kubert was also chosen as the penciller to launch the ultimate universe version of Marvel's first family, the Ultimate Fantastic Four, once again with writers Mark Millar and Brian Michael Bendis. Both series launched to commercial and critical acclaim, firmly establishing Kubert as an industry heavyweight and one of Marvel's "go-to guys" for their major projects.

An accomplished inker, he received an Eisner Award for his inking duties on the Dark Horse-DC Comics Batman vs. Predator crossover in the early 1990s. In addition to this, Kubert is well renowned for his lettering ability, being the youngest professional comic book letterer at the age of only 11 years old. His very own handwriting was used as the template for the font used in the Ultimate X-men comics, additionally Kubert's early lettering work on the now defunct Heavy Metal magazine was used by DC comics as the basis for most of the fonts used in their comics and magazines.

Both Adam and his brother Andy signed exclusive contracts to work for DC Comics in 2005. (At the same time, their father wrote a Sgt. Rock mini-series for the company.) This came as somewhat of a shock to the industry as both the Kuberts (along with John Romita, Jr.) were known as Marvel's stalwarts, and they were well known for their company loyalty. When Valiant Comics tried to lure the brothers over from Marvel in 1994 for exorbitant sums of money, they both blindly refused opting to keep their home at Marvel Comics. In an interview for the magazine Wizard, the brothers made clear that they held no animosity for Marvel, but instead were excited for the chance to work on DC titles for a change. The brothers also work as teachers at the Joe Kubert School, founded by their father (who also teaches there). Adam teaches first year classes, Andy second, and Joe third.

Kubert illustrated Superman: Last Son, co-written by Geoff Johns and Richard Donner (director of the 1978 film Superman) – his first project for DC Comics. He was to begin contributing to the story arc with Action Comics #841 (July 2006). However, he was not involved until issue #844, published in October 2006.

Issue #845 was released on December 3, 2006 to similar acclaim and again DC had to go back to press for a second printing on the February 23, 2007. Issue #846, part 3 of the "Superman: Last Son" storyline, was originally scheduled to be released December 30, 2006 was released on February 28, 2007. The next part of the story was scheduled to be a 3D issue released in April 2007. Further delay forced DC Comics to bring in substitute creative teams and delay the fourth part of the "Last Son" storyline and 3D issue to #851, which was released in early July 2007.

According to a April 2007 post on the Internet forum Newsarama, Johns stated that the delay was made to accommodate Kubert's schedule and that the final part of the "Last Son" storyline would be in Action Comics Annual #11. The annual went on sale on May 7, 2008.

Following his work on Superman he penciled the Final Crisis tie in, DC Universe: Last Will and Testament, written by Brad Meltzer.

His last work for his latest tenure at DC was the "Batman and The Outsiders Special," released in February 2009. This issue, written by Peter Tomasi, highlighted Alfred Pennyworth's efforts to recruit a new team of Outsiders in the wake of Batman's apparent death. After the release of the book, Kubert said he was pleased with his work at DC and had done, "what set out to do," which was to draw Superman.

May 2009 marked Adam Kubert's return to Marvel, his first interior work being published as one of two stories in Wolverine #73.

While he has returned to penciling for Marvel, he will continue to work for DC, contributing the stories for the upcoming Wednesday Comics Sgt. Rock feature, drawn by his father.
