Marie D'Ancanto is a mutant who can absorb the life force from other people and mutants; doing the latter gives her the abilities of the mutant she touches. Terrified by her powers, Marie left home and adopted the name Rogue. Later, Rogue joined Xavier's School for Gifted Youngsters and trained to be a member of the X-Men.
Marie D'Ancanto grew up in Meridian, Mississippi but ran away from home after her power manifested. After kissing her boyfriend, she started draining his life energy and he was consequently left into a coma. Afraid of herself and how she could hurt others, she left her home and ended up in a fight bar in Canada. Not really knowing what to do she stayed there for a while and happened to witness a fight between Logan and another man who had figured out that he was a mutant. Believing he would understand her, she hid in his truck but was soon caught. Unable to leave her alone on the road, he agreed to give her a ride; as he drove she explained how she was incapable of touching people without hurting them, and they quickly bonded. Soon after, they were attacked by Sabretooth who seemed to be after Wolverine; however Cyclops and Storm arrived at the scene and managed to get rid of Sabertooth and save both Wolverine and Rogue from an explosion. She was then introduced to the X-Men and given a room at the mansion, she became friends with Bobby Drake, although she remained shy and distant fearing to hurt any of them. Shortly after being welcomed she became involved in an accident with Logan. While trying to sleep she heard Logan having a nightmare and tried to wake him. However, in his rage, Logan stabbed her in the chest with his claws. Terrified he started to ask for help, the injured Rogue touched Logan's face in order to absorb his healing abilities but as she did so, his life force was drained too. Scott, Jean and Storm tried to help Logan, who seemed to be unwell. Frightened and scared of what she had done, Rogue tried to calm down, but was tricked by Mystique in the form of Bobby and decided to leave the mansion. Magneto attempted to capture her at a train station, and succeeded as the X-Men believed Magneto was really after Wolverine. When Senator Kelly arrived at the mansion, the X-Men realized that Magneto intended to use her to absorb his abilities in order to power a machine that could only be operated using his magnetism, but weakens the user so much that it will kill them if it used for long periods of time. Magneto intended to use the machine to mutate world leaders. The X-Men (Cyclops, Storm, Jean and Wolverine) stopped the plan, but Rogue was left with the white streak in her hair from the stress of using Magneto's machine.
Rogue begins dating Bobby, despite her continued difficulties making direct physical contact, a factor which frustrates both of them. When the X-Mansion is attacked, Rogue escapes with Logan, Bobby and John. Rogue and the other X-Men also manage to escape William Stryker who sends agents into the X-Mansion to kidnap the mutants. Rogue, Bobby, John, and Logan escape to Bobby's family home in Boston. They escape to Bobby's house, which at one point, Bobby is overcome by the sight of Rogue with minimal clothes on and kisses her, which at first seems successful and carries on for longer than either of them expected it to, but soon he is forced to pull away when her powers inevitably start harming him. However, Ronnie, Bobby's younger brother, scared by the "gifts" of his older brother, calls the police on the group. When they arrive, Wolverine is shot in the head by a policeman, and an enraged John manages to destroy many of the police and their vehicles. Rogue touches John's skin and absorbs his powers, enabling her to calm the flames. This scene depicts Rogue also absorbing the emotions of others unlike other scenes in the trilogy, as she seems to be grimacing while calming the destruction that Pyro has created. Soon Storm and Jean come to the rescue. In the X-Jet, Rogue is thrown out of the jet, but is rescued by Nightcrawler, she thanks him. Later Rogue is seen steering the X-Jet when the others are absent, in an attempt to save the X-men. Both Rogue and Iceman are eventually promoted to the front line X-Men team and are given uniforms similar to the other X-Men at the conclusion of the film, when Xavier and the X-Men team meet the President in the White House.
A pharmaceutical company announces that they have a cure for the mutant gene. Rogue expresses interest in being cured, evidently still longing to touch someone. When Iceman begins to develop a friendship with Kitty Pryde, and especially after seeing them "hugging" during a training session (they did it to avoid a missile that almost hit them) and after watching them ice skate together, she is encouraged more so. Upset, Rogue leaves to seek out the cure; Iceman follows her to the pharmaceutical company, but cannot find her. At the very end of the film, she comes back to the school, simply saying, "I'm sorry, I had to". When Iceman expresses disappointment and says it was not what he wanted, she says, "I know. It's what I wanted". It is revealed Rogue had taken the cure, and they hold hands, Rogue bare handed. An alternate ending reveals that Rogue ultimately decided against taking the cure and holds Iceman's hand with gloves on, but Iceman chooses her over Kitty, saying sorry to her.
When Logan woke up after changing the past, Rogue came out of her room and took Bobby's hand, smiling at Logan before walking away.
