Summary:

In which after closing the gate and defeating the Mind Flayer, El Hopper finds an injured red-haired teenager with amnesia in her backyard, and is convinced that she is just like her.

Jean Grey, after the events of X-men Dark Phoenix, dies in a burst of energy in the form of a phoenix.

Or so the X-men presumed.

The Phoenix Force that resides within Jean, is an immortal and immutable manifestation of the universal force of life and passion. Born of the void between states of being, the Phoenix Force is a child of the universe. It is the nexus of all psionic energy that does, has, and ever will exist in all realities of the multiverse.

It is described as being "the embodiment of the very passion of Creation-the spark that gave life to the Universe, the flame that will ultimately consume it."

So what if when Jean "sacrificed" herself for the sake of all humanity, she accidentally traveled to an alternate dimension?

CHARACTER BIOGRAPHY:-

Jean Elaine Grey was born the daughter of John and Elaine Grey. John Grey was a professor at Bard College in upstate New York. Jean's childhood and her relations with her family has been stable, and she had loving family life.

Jean is a member of a subspecies of humans known as Mutants, who are born with superhuman abilities. She was born with telepathic and telekinetic powers.

She is a caring, nurturing figure, but she also had to deal with being an Omega-level mutant and the physical manifestation of the cosmic Phoenix Force.

Jean's mutant powers of telepathy and telekinesis first manifested when she was in a car with her parents, and caused an accident that lead to their deaths. The event left her comatose, and she was brought back to consciousness and helped by powerful mutant telepath, Charles Xavier.

Xavier blocked her telepathy until she was old enough to be able to control it, leaving her with access only to her telekinetic powers, then Charles removed Jean's mental blocks and she was able to use and control her telepathic powers. More importantly, he mentally blocked the truth of her parents' accident from her memories to protect her.

She was then later recruited by Professor Xavier as a teenager to be part of his X-Men team after they defeated En Sabah Nur.

(Summary for those who didn't watch Dark Phoenix)

The President of the United States summoned the X-men for assistance during a crisis and respond to a distress signal from the space shuttle Endeavour, which is critically damaged by a solar flare-like energy.

While the X-Men saved all of the astronauts, Jean was stranded and was struck by the energy which she absorbed into her body to save the X-Men's aircraft from destruction.

Jean survived the event and her psychic powers were greatly amplified as a result. At the same time, the mental block placed by Xavier was destroyed and she accidentally unleashed her power on the mutants celebrating at Xavier's school.

She then traveled to her childhood hometown after discovering that her father was still alive.

Wrestling with this increasingly unstable power as well as her own personal demons, Jean spirals out of control.

The X-Men attempted to take Jean home but she injured Peter Maximoff and accidentally killed her friend, Raven, before flying away.

Jean then meets with Vuk, the leader of a shape-shifting alien race known as the D'Bari, who explained to her that she has been possessed by a force of cosmic power which wiped out the D'Bari home planet years ago. The power had consumed all those it came across until it was drawn to Jean.

Jean, after being attacked by Magneto and the mutants he recruited, lashes out and attacks them until Xavier convinces her to read his memories - allowing her personality to resurface.

Feeling remorseful, Jean offers to let Vuk take the force from her; however, it is revealed that doing so would kill Jean.

Xavier and Scott were able to prevent Vuk from fully absorbing the force from Jean, though Jean loses consciousness from the ordeal.

Xavier conferred with Jean within his mind, allowing Jean's personality to gain control of the force within her. After forgiving Xavier, Jean saves the mutants from Vuk's attacks and before proceeding to easily disintegrate the D'Bari forces under Buk's command when they attack her.

Vuk once again attempts to drain Jean of the force, but Jean takes Vuk into outer space, retakes the power that Vuk had received earlier, and then kills her. Jean then disappears in a burst of energy in the form of a phoenix.

Jean Grey's "death" and travel across the multiverse caused her sustainable physical and mental damage. Thus, her own brain developed a protective mechanism in which multiple mental blocks - developing amnesia- occurred. All to enable her to cope with the events she's been through.

PERSONALITY:-

Loving: Jean has an incredible capacity for love, and this is one of her most important personality traits. It is one of the things that make Jean undoubtedly Jean-ish. It isn't that she loves her family, friends, and those at the school; it's that she loves life, and she loves humanity. She has such grand hopes for /people, and despite some of the more horrific things she's witnessed, she still has hope and love in her heart. There is nothing she would not do for what she loves, even if it means sacrificing herself to ensure the safety of that which she holds dear.

Determined: Some might call it pure stubbornness -- and they wouldn't exactly be wrong -- but Jean prefers to think of herself as determined. Driven. Feisty. She doesn't take crap from anyone (not /even/ Scott Summers), and when she has something to say she is not afraid to speak up. Jean might know when she is beaten, but she doesn't know when to stay down and give up.

Idealist: Jean is an idealist to the core. She truly and deeply believes in Charles Xavier's dream of equality for mutants, and that someday in the very near future, mutants can live and progress peacefully with non-mutants.

Selfless: Jean is naturally selfless, always giving and genuinely concerned about the welfare and happiness of not only those nearest and dearest, but humanity as a whole. She is the type that would give her last dollar to someone in need, or do without lunch in order to feed someone less fortunate to herself. However, this all keeps Jean rather too busy to look after her own self, so she sometimes suffers because of it.

Soft-Hearted: Anyone with a sob story or just needs a little help to get them through gets Jean all tender-hearted and wanting to help. She is the sort of person who can't resist bringing home a lost or stray animal and trying to find it a good home. The problem is that this drives her to try and reach out, even when it puts her in danger. Sometimes, she just can't see the forest for the trees.

Wild Streak: Perhaps it's a red-head thing, but Jean Grey, despite what some might think, has a wild streak in her. There's a part of her that just craves the freedom of breaking convention and going a little crazy. She loves fast cars, or riding on the back of a motorcycle that's taking curves way too fast. There are times when she even revels in the exhilaration of using her powers in combat, which becomes especially dangerous when she's pushing her limits.

POWERS AND ABILITIES:-

Telepathy:-

When her powers first manifested, Jean was unable to cope with her telepathic abilities, forcing Professor Charles Xavier to suppress her access to it altogether. Instead, he chose to train her in the use of her psychokinetic abilities while allowing her telepathy to grow at its natural rate before reintroducing it.

Jean Grey can detect and read the thoughts of others, project her own thoughts into other's minds, form psychic links with other beings, control others' minds so as to manipulate their physical functions, mentally stun opponents with bolts of pure psionic force, cast near-flawless mental illusions, and project her mind and the minds of others onto the astral plane. At close range, she can manipulate almost any number of minds; however, she can only take full possession of another's mind one at a time and can only do so if she is within that being's physical presence.

As a side effect of her telepathy, she has an eidetic memory.

Telekinesis:-

Jean possesses a high-level of telekinetic ability that enables her to psionically levitate and rapidly move about all manner of animate and inanimate matter. She can use her telekinetic abilities on herself or others to simulate the power of flight or levitation, stimulate molecules to increase friction, create protective force fields out of psychokinetic energy, or project her telekinetic energy as purely concussive force. The outer limits of her telekinetic power have never been clearly established, though she was capable of lifting approximately fifty tons of rubble with some strain.

Phoenix Force:-

While empowered by the Phoenix Force, Grey has total telekinetic control of matter at the molecular level, allowing her to manipulate atomic structures on a universal scale. She can generate any form of energy in seemingly unlimited amounts, as well as absorb energy from sources as great as a supernova or even convert her physical form to pure energy and back again.

She can also exist in virtually any environment without harm and create space/time warps to travel through hyperspace or traverse the timestream, and her telepathic abilities are also vastly enhanced.

When using her power, the Phoenix Force will manifest itself around Grey in the form of a bird of cosmic flame, the size of the bird varying with the amount of energy she is using. [These flames can even manifests in seemingly impossible situations, such as the vacuum of space or underwater. This fire apparently does not require oxygen to burn, and burns so intensely that matter is consumed without by-products such as ash. The cosmic fire is a literal punctuation to the Phoenix's purpose to "burn away what doesn't work", as well as being described as "burning through lies and deception".]

The Phoenix Force can also resurrect the dead under some conditions, and absorb the life force from other sentient beings to bolster its own.

A/N:-

Sorry if you find this chapter boring, but I think it's necessary for those who aren't Marvel nerds to know Jean before delving into the story.

In this version, Jean Grey is eighteen years old, unlike in Dark Phoenix where she's in her 20s.
