Dark Phoenix is a extremely powerful superhuman entity closely affilliated with Jean Grey.
Dark Phoenix was a human named Jean Grey. the Phoenix Force's fall from grace - a state wherein it became corrupted by power. The Phoenix entity became too strong to control for the merely human aspects it had acquired from Jean, but the other X-Men had no way to know what was happening and little chance of preventing a tragedy. Professor X helped Jean establish "psychic circuit breakers" in her mind, but they became less and less effective.
She was thus an easy target for the illusionist Mastermind, who needed a trophy to join the Inner Circle of the prestigious (and infamous) Hellfire Club. With the help of a psionic device created by the club's White Queen, Emma Frost, Mastermind made Jean believe that she was his 18th-century lover Lady Grey. Jean joined the club as their Black Queen, which would allow her to relish the extremes of human emotion and sensuality. When the X-Men came to her rescue, Jean's true love, Cyclops, faced Mastermind in a psychic duel and was defeated. His "death" broke Mastermind's hold over Jean's psyche--as well as any control Jean had had over the Phoenix. It brushed aside the X-Men and departed for the heavens.
To sate its hunger, the (now Dark) Phoenix flew to a distant galaxy and devoured the star of the D'Bari system. The resulting nova killed billions of innocent people. A Shi'ar vessel attacked it and managed to alert the Shi'ar Empress Lilandra before they were destroyed. The empress called a council of her intergalactic counterparts, including the Kree and Skrull empires. They concluded that, for the rest of the universe to live, Dark Phoenix must die.Meanwhile, the Beast had found a way to neutralize Phoenix's power temporarily. When it returned to Earth, the X-Men held it at bay while Professor X rebuilt the circuit breakers in Jean's mind. At that moment the Shi'ar arrived and teleported everyone aboard their flagship. Lilandra announced that Phoenix, and thus Jean Grey-Summers, would have to die. Jean received a Kree weapon so that she could "do the right thing." Professor X, unwilling to give up on one of his pupils, but romantically involved with Lilandra, challenged her to Arin'n Haelar, a Shi'ar duel of honor that cannot be refused. Professor X named the X-Men as his champions in the duel, Lilandra her Imperial Guard.
The duel took place the next day in the Blue Area of the Moon. The Imperial Guard made short work of the X-Men, leaving Cyclops and Phoenix to make a final stand. A stray bolt hit Cyclops. Jean's control broke, and she became the Dark Phoenix again. Lilandra ordered Plan Omega, which would destroy the whole solar system in hopes of eliminating Dark Phoenix as well. Professor X ordered the X-Men to subdue Jean so that Plan Omega would not be necessary, and they managed to subdue the Phoenix for a brief time. In this moment of lucidity, Jean took Cyclops to a back alley, where she bade him an emotional farewell and turned the Kree weapon on herself.
The story ends with Uatu the Watcher's comment: "Jean Grey could have lived to become a god, but it was more important to her that she died as a human."
Powers and AbilitiesEdit
Known Powers: Like Jean Grey-Summers, the Dark Phoenix used telepathy and telekinesis, but at a much higher level. She was able to rearrange the molecular structure of matter and fly at supersonic speeds. Using the Phoenix Force, she could travel through hyperspace and destroy Shi'ar battlecruisers with little effort.
Known Abilities: Because Phoenix was linked to Jean's psyche, she maintained a psychic link with Cyclops.
Strength Level: As Jean Grey-Summers, the Phoenix possessed the normal human strength of a woman of her age, height, and build who engaged in moderate regular exercise. Using her cosmic powers and telekinesis, Phoenix could lift an unknown amount, probably in the range of thousands of tons.
Appearances in other mediaEdit
In the movie X-Men: The Last Stand, it is revealed that Jean is a "Class 5" mutant, arguably making her the most powerful mutant in existence. In this film, Jean appears as the Dark Phoenix. When using her Phoenix powers, Jean's appearance changes considerably: her skin becomes dark and veiny, her eyes turn black (although fire can be seen in her irises at some points in the film), and the color of her hair changes from its natural dark red to a bright, almost fire-like, reddish-orange. As a child, Xavier put psychic blocks around Jean's subconscious mind to keep her immense powers at bay. As a result, Jean developed a split personality called "Phoenix." Phoenix emerges from the lake where Jean had died and apparently kills Scott Summers. During a confrontation with Professor X at Jean's childhood home, Phoenix lashes out and lifts Xavier out of his wheelchair with her telekinesis and horrifically atomizes him, destroying the house in the process (caused when her outburst of power causes everything in the house thats not nailed to the floor to crash up onto the celing, and then causes the entire house to float up in midair). After she kills Xavier, she leaves the ruins of her old home with Magneto and joins, albeit unofficially, the Brotherhood of Mutants. During the attack on Worthington Labs, Phoenix resurfaces when a group of soldiers fire cure darts at Jean. Phoenix freezes them in place and disintegrates them along with the soldiers. She then goes on a rampage and destroys much of Alcatraz Island, killing mutants and humans alike. Wolverine gets Jean to resurface by professing his love for her. Since she can't control Phoenix for long, Jean pleads with him to kill her rather than let her harm more people. He fatally stabs her with his claws, and as the freakish features of Phoenix dissipate, Jean becomes herself once again before dying. The ending scenes show her buried alongside Cyclops and Xavier on the Institute's grounds.

Uncanny X-Men 101-132 Uncanny X-Men 132-134 Phoenix (Phoenix Force) took the name "Jean Grey-Summers" in Uncanny X-Men 101 and maintained that impersonation throughout the Dark Phoenix Saga, although neither Phoenix nor Dark Phoenix was actually Jean.
