It is the nexus of all psionic energy of the past, present, and future in all realities of the multiverse, the Guardian of Creation and of the dangerously powerful M'Kraan Crystal.

"[citation needed] During its time as a sentient and formless mass of energy, it traveled the cosmos and was worshiped by several alien races, including the Shi'ar, who named the entity Phal'kon, the "sister" of their other gods K'ythri and Sharra.

The Phoenix is drawn to Earth when Firehair, a young primitive female red-haired mutant overwhelmed with despair by her friends' deaths, contemplates turning her psychic abilities on herself to commit suicide at the "Burnt Place".

Attracted to Firehair's untapped raw psychic power, the Phoenix prevents the suicide, bonds with her, and seeks to use her to fulfill its intended purpose of razing planets to ashes.

Consumed by vengeful rage, Firehair nearly gives in to the firebird's bloodlust to become a Dark Phoenix, but is pacified by her wolf guardian and decides to use her powers to protect those weaker than herself.

[7] At some point, the entity ends up in Shi'ar space, where it bonds with a citizen of the Empire named Rook'shir, who controls the power of the Phoenix Force in conjunction with his blade.

[9] In the late fifteenth or early sixteenth century, Yu-Ti of K'un-L'un has visions of the Phoenix coming to Earth and of a red-headed Iron Fist who would confront it.

After committing suicide, the Phoenix Force reaches the Hot White Room where it encounters a manifestation of Death and returns itself to Jean in the cocoon.

Galactus accuses the Phoenix Force of hypocrisy and reveals to it that its existence in a corporeal state is sustained by robbing energy used to birth future generations.

Realizing this to be true, the Phoenix vows to return to its prior existence of "touching all that is" while allowing an echo of its power to remain with Rachel's now-dominant consciousness.

[30] On the way back to her time, Captain Britain is lost in the timestream and Rachel is forced to switch places with him, as she does not belong in the timeline she had existed in.

In hopes of eliminating the possibility of a new Omega-level psionic mutant becoming a host for the Phoenix Force, the Shi'ar sent a commando unit—the Death Commandos—with the purpose of wiping out the Grey genome and killing Quentin Quire to Earth.

[43] During a conflict with several Predators X (genetically engineered mutant hunters), the Stepford Cuckoos are overwhelmed and knocked unconscious as the fragment of the Phoenix they captured forcefully escape from the girls' diamond hearts.

[58] Spider-Man then baits Colossus and Magik into taking each other out by playing off of their fears when fighting them in a volcano, forcing their portions of the Phoenix to be divided between Emma and Cyclops.

[60] Emma had been using the Phoenix Force to control all of Utopia, read the thoughts of everyone on the planet, take vengeance on anyone who had ever harmed a mutant, and dismantle all Sentinels.

Together, Hope and the Scarlet Witch wish away the Phoenix Force and the damage it caused, in the process activating the X-gene that allows the creation of new mutants around the world.

[80] Strange psychic occurrences around the world, which include a large bird flaring out from the sun and an explosion on the moon, raises red flags for the X-Men, who quickly launch an investigation on these events.

[83] The X-Men theorize that the strange psychic occurrences are subconscious cries for help made by Jean Grey, and they must try to stop the Phoenix Force from merging with her.

[85] Namor, embittered by the surface world's reckless disregard for his underwater kingdom, beckons the Phoenix Force to Earth and vows to sacrifice every part of himself to reunite with the entity once more.

Once on the ground, Black Panther and Ghost Rider get to work, calling back the Spirit of Vengeance, Iron Fist and Eye of Agamotto out of Khonshu's grasp.

The entity selects Captain America and Doctor Doom as its first combatants, who are empowered by a small spark of the Phoenix's cosmic fire and transported to the Savage Land for their match.

As Doom is returned, Captain America is transported to the White Hot Room where he encounters other competitors chosen by the Phoenix being held in wait for the next match.

While stopping a burglary, she loses control of her temper and burns one of the perpetrators alive before starting a fire that threatens to harm countless innocent people.

Even Echo's behavior along with her attitude and body language shifts dramatically when being influenced by the Phoenix Force, prompting Elektra and Forge to confront her over the dangers of her powers.

[139] Quentin Quire is revealed to be a host in the Here Comes Tomorrow storyline and in the visions of Deathlok,[140] and in the timeline of Nocturne, the Phoenix Force possesses Colossus' soulless body and reshapes it into a female form.

[145] In Defenders: Beyond #3, by Al Ewing and Javier Rodriguez, it appears the white void, the tower, a dark cave lit by a single fire, a snowy landscape, and an endless expanse of desert.

[181] In some conditions, a bit of cosmic fire can easily burn anything it comes into contact, as when it possesses young Jean Grey she unconsciously melts the equipment the medics try to put on her.

Jean Grey as The White Phoenix of the Crown is able to change the future of a universe by reaching back in time and urging Cyclops to move on with his life.

It can manipulate matter on a sub-atomic level and transmute elements, like turning wood to gold or stone to crystal; on a smaller scale, it can alter the molecular fabrics.

If an avatar of the Phoenix Force is harmed or killed, it forms an "egg" of cosmic power around them that is incubated in the White Hot Room, and hatches out completely healed.
