Played by: Michael J. Fox and Elisabeth Shue
As a couple, Marty and Jennifer withstood the test of time, albeit in a whole new way thanks to the time-traveling DeLorean. While visiting the past in the first film, Marty almost hooked up with his mom as a teenager, while Jennifer got subjected to a grim look at what could have been her future with Marty in Part II. Time machine or not, they proved to be timeless.
