in back to the future part ii marty and dr. emmett brown go to which future date
Back to the Future Part II On October 26, 1985, Dr. Emmett Brown arrives in the DeLorean time machine and persuades Marty McFly and his girlfriend, Jennifer Parker, to travel to the future with him, and help their future children. Biff Tannen witnesses their departure. They arrive on October 21, 2015, where Doc electronically knocks out Jennifer, and leaves her asleep in an alley, explaining that she should not have too much knowledge of future events. He has Marty pose as his own son and lookalike Marty Jr. to refuse an offer to participate in a robbery with Biff's grandson Griff, thus saving both of Marty's children from prison.
List of Back to the Future characters Douglas J. Needles (portrayed by Flea in Back to the Future Part II and Back to the Future Part III) is an acquaintance of Marty McFly and Jennifer Parker from Hill Valley High School. Like his school's alumnus, Biff Tannen, Needles also has his own gang (portrayed by Christopher Wynne, J.J. Cohen, and Ricky Dean Logan) and develops a rivalry with Marty. Needles often goads Marty into doing reckless things such as a street race that leads Marty to crash into a Rolls Royce and an illegal transaction which results in his firing in 2015.
