On October 26, 1985, Doc Brown and Marty McFly traveled to October 21, 2015. The elderly Biff Tannen stole the DeLorean time machine with the intention of giving his younger self a Grays Sports Almanac to make himself rich. He didn't know how to work the DeLorean, so he hit the time circuits with his cane. Once he reached 88 m.p.h., he was sent to the Cretaceous Period. The Mr. Fusion was empty, so he tried to find some organic material to fuel it. A baby velociraptor stole the Blast from the Past bag with the almanac in it. Biff killed the dinosaur by hitting it in the head with his cane, and used the dinosaur's body to fuel the Mr. Fusion. He then headed to November 12, 1955.
Behind the scenes
- The title of the comic, Jurassic Biff, is a reference to the film Jurassic Park, rather than the period to which Biff traveled. Velociraptors did not exist during the Jurassic period.
