The timing may have nothing to do with last week’s Twilight of DC’s office, but Marvel Comics Executive Editor Mike Marts leaving a post where he was clearly being groomed for big things to go to a START-UP, is an interesting comment on the state of the American comics industry. Marts confirmed on Twitter that he was leaving Marvel for AfterShock Comics, a new venture with writer Joe Pruett. Deadline has more details. Pruett has written X-Men titles for Marvel. Marts was working on various high profile titles including Guardians of the Galaxy and X-Men comics. Marts will become Editor-in-Chief of Aftershock comics after pingponging back between MArvel and Dc for a career that started in 1996.
