IDW published a mini-series which presents the first meeting of both Marty and Doc Brown and is written by co-screenwriter Bob Gale, which was released in stores on October 21, 2015, the same date that Marty travels with Doc Brown to the future depicted in the storyline for Part II. In issue #3, it was revealed that it had become an ongoing monthly comic due to popular demand. Beginning in issue #6, the original format of one or two untold stories per issue was replaced with a multi-issue ongoing story arc.
