Since 2003, McKelvie has collaborated with
Kieron Gillen on a number of works. This started with a
comic strip for PlayStation Official Magazine – UK, entitled Save Point, which ran for at least three years.[1]The Guardian highlighted that Gillen and McKelvie "met in 2003 at a convention where Gillen was selling his first photocopied comics".[2] Their first
comic book together was Phonogram, a six-issue series in 2006, which was followed by two sequel series in 2008 and 2015 with
Matt Wilson.[3][4] The three worked together on a relaunch of Young Avengers for Marvel in 2013,[5] and created the 45-issue series The Wicked + The Divine between 2014 and 2019.[6] In 2021, GamesRadar+ highlighted that the duo has "worked together on-and-off for the past 17 years" and that their
Batman short story Batman: Black and White #5 was their "first major project together since the conclusion of The Wicked + The Divine in 2019".[7]
His first creator-owned series as both writer and artist, Suburban Glamour, was published in 2008, with Guy Major and
Matthew Wilson as colourists. He has done various work for
Marvel Comics, including a run on Defenders with
Matt Fraction, and the X-Men: Season One graphic novel with
Dennis Hopeless.
McKelvie has redesigned a number of characters' costumes, including the 2012 redesign of long-time character
Carol Danvers, for a relaunch of the character as the new Captain Marvel,[14] and in late 2013, the design for Kamala Khan's outfit when she becomes
Ms Marvel.[15] He has also made available his personal takes on
Wonder Woman,[16]Iron Man[17] and
Cyclops.[18]
McKelvie has said that he emphasises practicality when creating his Marvel designs, stating that he considers the "message a [..] character's design is putting across",[19] and specifically for Ms. Marvel, the design reflects "the Captain Marvel legacy, and also her story and her background".[20]
