Back to the Past Part II was released late 2016 and was a follow up to 2014's Back to the Past film. It once again features Doc and Marty but also sees the addition of Dylan from the Average Heroes series. Back to the Past Part II takes place after the first episode of Average Heroes.
During a battle between a team of Superheroes and Crossbones, debris from an explosion hits the Delorean causing it to malfunction, sending Doc, Marty, and Dylan back in time 65 million years. They must hurry and get back before the perils of the time period catch up with them.
