She is a teenage mutant who, along with her older sister Sara, was born with powerful abilities of telepathy and telekinesis. Sometime after the sisters were abandoned by their mother at an early age, Sara was abducted by the Department of Damage Control, led by William Metzger, who saw her as a freak in society and aimed to experiment with her powers. Having received a vague message of something called "V-Max" from her sister Sara, Jean would use her powers to body-surf through multiple people in order to find V-Max across New York City, waging a destructive campaign against the DODC and anyone she believes stands in her way. Ultimately, this led to her clashing with Spider-Man, the only person who could resist her powers and who worked with Damage Control to apprehend her as he found her dangerous. After being detained, Jean spirals into a state of vengeful grief after learning of Sara's death during Damage Control's experiments, using her newfound telekinesis to entrap those around her in New York City. In the end, however, Jean was able to come to terms with herself when Peter, who learned the truth about her tragic past, allowed her to enter in his mind, who understood her loss and accepted her for who she truly is. Jean is a haunting figure draped in a dark, hooded cloak that conceals her face in shadow. Her eyes, barely visible beneath the hood, are occasionally seen glowing with an eerie psychic energy. She is frequently described as "invisible" due to her ability to appear as anyone or no one at all. When unmasked, she reveals herself to be a young teenage girl with auburn redhead hair, blue eyes, while she keeps a hair tie that once belonged to her sister as a memento. Jean Grey is a manipulative and possessive being that operates entirely from the shadows. As Bill Metzger describes her, she is "a threat that can be anyone", a terrifyingly elusive enemy that cannot be traced, tracked or contained by conventional means. She takes a chilling pleasure in psychologically tormenting her victims, casually taunting Spider-Man through the bodies of innocent civilians and manipulating Bruce Banner to the point of breaking his control over the Hulk. She is relentless in her assault on Damage Control, and proves capable of striking cruelty. Her baiting Peter into thinking that MJ has recovered her memories when, in fact, Jean was puppeteering her, actually leads Peter to tell her that she has crossed the line. Her resentment of those around her is driven by a combination of desperation to save her sister and her rage at the world's cruelty, in response from being outcasted for her mutation, as well as losing her sister Sara from Damage Control, who took her away to be experimented on. As destructive and ruthless as she is, Jean isn't causing chaos for fun and is in desperation to save her sister from her captors. Peter notes that she's not a killer and his compassion for her helps Jean break out of the self-destructive spiral she's been on, allowing her to repay that same compassion in return by healing him when he took a bullet for her from the Punisher. Jean and her sister Sara were born with telepathic powers, which caused their mother to kicked them off their home, forcing them to fend for themselves. One day when Sara is training Jean to use her powers, the Department of Damage Control took Sara for experimentation. Jean attempted to save her, only for Sara to use her powers to possess Jean so she can leave from a distance far from the DODC’s grasp. She got transferred from many foster homes only for her to escape them, which forced the DODC to erase her information from many governmental databases to avoid suspicion of their involvement. One day Jean received a telepathic message from Sara, something regarding "V-Max". Giving clues to Sara’s whereabouts, Jean decided to rescue her sister from the DODC. Grey is a mutant who can read, communicate, and control the minds of others. Jean can read minds, manipulate the thoughts and mental faculties of others, and also project her own thoughts onto others, effectively broadcasting her messages to specific individuals. With her telepathy, she can delve into the deepest recesses of someone's mind, uncovering their innermost secrets and desires. She can force others to do her bidding, creating "thralls". Using her powers she can manipulate and influence the thoughts and behaviors of individuals, exerting control over their minds and actions. One of her abilities is the capability to take control of someone else's thoughts and utilize their body as her own. She can jump between hosts at will, taking control of anyone she chooses. When taking control of a host, Jean automatically gains their fine motor skills and prowess, allowing her to perfectly replicate movements and fighting styles they would normally be able to do if they were in control. She is seemingly also able to carry on these skills even when possessing someone completely different, as shown early in the film when she was able to drive a tank despite possessing an old lady. Jean can read the memories of whomever she jumps into, and in some cases even experience them for herself.
