"A teenage girl stepped into the living room at the bottom of the stairs. Oh, my God! Jennifer [watching through the slats of the louvered closet door] breathed in sharply. The teenager was the spitting image of Marty!" —From Back to the Future Part II by Craig Shaw Gardner (quote, page 69)

"The teenager [Marlene] shrugged her broad shoulders. She was built sort of huskily for a girl, Jennifer thought, probably one of those high school athletic types." —From Back to the Future Part II by Craig Shaw Gardner (quote, page 70)

Marlene McFly was the daughter of Marty McFly and Jennifer Parker, and sister to Marty Jr.

Marlene, like her brother, looked very much like her father. She appeared to like talking to her friends on the video telephone, and seeing her grandparents; she seemed to get along very well with her Grandma Lorraine in particular. Otherwise, little else is known about her personality.

Biography

In the original timeline, after her brother was tried in a data-court and ended up going to prison for fifteen years due to being involved with Griff Tannen's plan to rob the Hill Valley Payroll Substation, Marlene hatched a plan to break him out of jail. About a week after October 22, 2015 (the date of the robbery, at 1:38 a.m.), Marlene attempted her plan, but was caught and sentenced to twenty years in prison. Dr. Emmett Brown, visiting from 1985, found out about this and traced everything back to the afternoon of October 21, when Griff had convinced Marty Jr. to join him. Doc headed back to 1985 to pick up Marty and Jennifer, who were just about to take a ride in Marty's new Toyota Hilux 4X4 and brought them to 2015.

In the revised timeline of the future, Marty pretended to be his son. By saying "no" to Griff, Marty managed to save his future family — Marty Jr. was now no longer involved in the robbery, and Marlene would not have to break him out of prison. Thus, both McFly siblings were safe.

Marlene attended the family dinner on the evening of October 21, where she was seen speaking to someone over her video glasses — possibly one of her friends. She was annoyed when her father asked her to pass the kelp tea, as well as when Douglas J. Needles, her father's co-worker, called a few minutes later, as the McFlys' only having one phone line meant she had to interrupt her conversation.

Behind the scenes

Marlene's age is disputable — a draft script for Back to the Future Part II says she is 17 in 2015, like her brother, thus putting her year of birth as 1998. However, there is no mention of them being twins, and many fans think that she may be a year or two older than Marty Jr. due to the way she acts. She appears to be within the 20 year range.

While Michael J. Fox portrays Marlene on screen, her voice is actually dubbed over by an uncredited Grey DeLisle.

In the novelization, Marlene became severely depressed after the arrest of her brother and committed suicide.
