Marlene McFly

Marlene McFly is the future daughter of Marty McFly and Jennifer Parker from Back to the Future - Part II. 
Like her father, her brother and ancestor, Seamus McFly, she is portrayed by Michael J. Fox.
==Role in the film==
===Original Timeline===
In 2015 Marlene attempted to break her brother out of prison after he takes the fall for a burglary constructed by Griff Tannen and his gang. Nonetheless, Marlene is caught and serves twenty years while her brother serves fifteen.
===New Timeline===
In the new timeline, her father's past self prevents this from happening by pretending to be Marty Jr. and refusing Griff. When Biff's descendant and his gang attempt to attack Marty, he outwits them on a hoverboard, manages to duck Griff's attack by jumping in the water fountain below, the gang flies into the city hall and are arrested. Because of these chain of events, the burglary never happens, Marty Jr. is never convicted to serving 15 years in prison which, in turn, does not cause Marlene to attempt to break him out or serve twenty years.
Marlene is physically seen in the film when she thinks hears her mother, Jennifer, coming home (in reality, her mother's past self. Coming down stairs, Marlene answers the door and welcomes her grandparents, Lorraine and George, wondering in concern what happened to her grandfather.
==Trivia==
*Marlene's age is disputed. An earlier draft for Back to the Future Part II says she is 17 in 2015, like her brother, therefore putting her year of birth as 1998.
**However, there is no mention on-screen of Marty Jr. and Marlene being twins, and many fans think that she may be a year or two older than Marty Jr. due to the way she acts, and appears to be within the 20-year range.
**Then again, Doc Brown's journal entry for November 12, 2015 appears to suggest otherwise: "The young lady pictured in the story [in USA Today] looked like a female version of Marty — no coincidence since she was his daughter! And her crime was attempting to break her twin brother, Martin McFly Junior, out of prison!" From DeLorean Time Machine: Doc Brown's Owner's Workshop Manual. Bob Gale and Joe Walser. ("Doc Brown's Journals: 2015" page 89)
*In the novelization, Marlene became severely depressed after the arrest of her brother and committed suicide.
