“Of course I’m a threat. Why? Did you think for a moment that I wasn’t?” – Emma Grace Frost
Emma Grace Frost made her debut in Uncanny X-Men #129 in 1980, during the Dark Phoenix Saga and created by Chris Claremont and John Byrne. Emma was leading member of an old Boston mercantile family that arrived from England in the 1600s and was the second of three daughters and had an older brother named Christian Frost who turned to substance abuse. The three Frost sisters were secretly mutants whose telepathic abilities manifested upon puberty and Emma was a social outcast while attending school and also suffered intense migraines. While in class, Emma would begin to hear other people’s thoughts and once her powers emerged, Emma used them to excel in all aspects of life, eventually deciding on a future in teaching.
After seeing Emma kissing Ian Kendall in front of the Frost estate, Winston Frost blackmailed her to give up teaching and when her brother’s gay lifestyle was revealed, Winston began alienating his son which resulted in his attempted suicide. When it was time to choose a worthy heir, Emma was chosen but refused in order to make her own way through life where she began working minimum wage jobs and stayed at a hotel. After attempting to pay for a meal with a newspaper using her abilities, Emma was caught and forced to wash dishes where she met Troy Kilkelly who she later moved in with.
Later when Troy was killed due to owing money to a loan shark, Emma absorbed the shark’s memories, faked a kidnapping which forced Winston to pay a ransom and then took the money with her to New York. Emma later found herself in the Essex Clinic where she was kidnaped by the Brotherhood of Evil Mutants and then taken to Xavier’s School for Gifted Youngsters by Magneto to kill all humans using Cerebro. During that time, Beast had created a device that shut-off access to cosmic rays of the Evolutionaries and when the remaining Evolutionary left, it erased the memory of their presence and returned Emma to the clinic.
Emma later dyed her hair blonde and enrolled at Empire State University where she is reunited with Kendall and also met Astrid Bloom who began training Emma in the use of her abilities. After learning Kendall was dating her roommate, Emma confessed her love to him and the two began seeing each other, but Christine threatened to expose his relationship with Emma if he didn’t leave her. Astrid then influenced Kendall to choke Christine and after learning the truth, Emma mentally defeated Astrid and absorbed her knowledge of telepathy, saving Kendall’s job and revealing her mutation, but he left Emma in disgust.
Emma then inherited a great amount of wealth and rose rapidly through the business world with the help of Dark Beast. After Emma became a majority stockholder renamed Frost International, she became chairperson and Chief Executive Officer. Emma also became chairperson of the Board of Trustees for the Massachusetts Academy where she served as the Headmistress. Eventually, Emma received an invite to the Hellfire Club as a stripper where she was approached by Professor Charles Xavier and Dr. Moira MacTaggart to join the X-Men but Emma refused so Xavier erased her memory against Vulcan’s judgment.
Frost later became the ally of Sebastian Shaw and the two staged a coup, giving them control of the Council of the Chosen which was renamed the Inner Circle and Emma became the White Queen. The Inner Circle was then dominated by mutants who were trained at the Massachusetts Academy and became part of the Hellions. When Shaw was in search for a new White King, he invited Namor who refused which sent Shaw into a frenzy and ordered Emma to force Namor to join. A few days later, Emma pretended to try and commit suicide to attract Namor’s attention so he rescued her and they spent the next two weeks in Atlantis.
After Shaw began growing tired of waiting, he sent Sentinels for Emma which caused damage to Atlantis and prompted Namor in taking the attack as a declaration of war. Namor and Emma went to the Inner Circle and clashed with the group until Namor left and vowed revenge. Emma later encountered the X-Men once again with she attempted to recruit Kitty Pryde but eventually defeated by the X-Men and Dazzler. When Kitty’s parents decided to let Kitty attend the Xavier School, Emma swapped bodies with Storm while Shaw attacked the X-Men with a new Sentinel model, but Storm managed to regain her body and the Sentinels were destroyed.
Later, Mastermind put Emma into a coma and when she awoke, she invited Doug Ramsey to her Academy as well as capturing Kitty so the New Mutants came to their rescue and Magik teleported the group away. While the New Mutants were battling the Beyonder, killed and recreated, the team was visited by Emma in her astral form to speak with Magneto and offered to rehabilitate them. Under the influence of Empath, Magneto sent the New Mutants to Emma’s Academy except Mirage and Warlock, but later raced to rescue them until the two decided to work together. Emma later met with Magneto and Shaw offered him a position in the Inner Circle.
Later, Emma allowed the Hellions to participate in a contest with the New Mutants to abduct Bird Brain and later, sent Empath home with Magma after her father ordered her. Emma then received a message from Empath stating Magma had been kidnapped so she contacted the Hellfire Club and Magneto who left to rescue Magma but she had already been saved. Upon returning, the Inner Circle and Magneto arrived to save the New Mutants from Sabretooth while Magneto later battled and defeated Shaw so he was voted out of the Inner Circle. Later, the X-Men joined the Hellions in protecting Emma from Trevor Fitzroy but he managed to drive her into a coma which brought an end to the Hellions.
When Emma recovered, she resumed her role as Headmistress of the Massachusetts Academy where she and Banshee trained Generation X. The Academy eventually closed after Synch’s death and Emma murdering Adrienne Frost so she began teaching in Genosha where she became one of a handful of survivors in the Sentinel Massacre. Emma then returned to the Xavier Institute to teach and took the Stepford Cuckoos under her wing while she and Hank also began a friendship. During a riot at the school by Quentin Quire, Sophie died when she used the drug Kick and Cerebra to subdue Quire and the Cuckoo’s abandoned Emma after blaming her.
Meanwhile, Emma began having a psychic affair with Scott Summers so the Cuckoos took their anger out by telling Jean Grey who then brutally tore through Emma’s memories and forced her to remember all things she’s repressed. After Jean was killed by Kuan-Yin Xorn, she encouraged Scott to begin a new life with Emma so the two acted as Co-Headmasters of the Xavier Institute. In the House of M, Emma was the first X-Man Wolverine contacted who was reawakened and sided with Logan to kill Scarlet Witch to return the world to normal. After M-Day, Emma abandoned the team during a fight to confer with a group of four individuals watching from the shadows and later began using her telepathy on Scott to help reverse the mental block he had in his mind preventing the controlled use of his powers.
Later, Emma and Scott are called to San Francisco where the X-Men aided the city in defeating Martinque so the mayor offered them refuge. After Norman Osborn is appointed Director, he convenes the Cabal so Emma joins the group as part of Scott’s plan and is later asked to lead a team of Dark X-Men. As tensions continue rising between the Dark X-Men and Avengers, Emma insists on touring the facility containing imprisoned mutants where she’s contacted by Xavier who informs her both he and Hank are being kept prisoner. Over the next several days, Emma takes her team around San Francisco to clean up riots in the city while also ensuring Mindee Cuckoo was arrested in order for her to lead the X-Men to the prison so Magik can save everyone.
After the alarm is raised, Emma betrays the Dark X-Men while taking Cloak, Dagger and Namor with her and X-Force to rejoin Scott on Utopia. With the Cabal crippled, Osborn orders the Dark Avengers and X-Men to kill Emma and Namor, but the teams are outnumbered and forced back. During this time, Emma also obtained a sliver of the Void so she remained in her diamond form in order to keep it from controlling her. Eventually, Scott attempted to enter Emma’s mind to extract the sliver but the Void sliver attempted to control him until he managed to seal it within his black box. After the attack on Utopia, Emma considered going with Logan to the Jean Grey School to pursue her love of teaching, but Scott begged her to stay and she instead joined the Extinction Team.
Emma sided with the X-Men during Avengers vs. X-Men where she was blocked by a nanocloud created by Iron Man which forced her to rely on her diamond form. Eventually the X-Men escaped in order to search for Hope Summers, later finding her on the Blue Area of the Moon so she, Cyclops, Namor, Colossus and Magik arrived to stop the Avengers from getting to Hope first. During a fight between the two teams Iron Man attacked the approaching Phoenix Force but instead of destroying it, the entity entered the X-Men to create the Phoenix Five. After the Five grabbed Hope, they returned to Earth and began using their powers to make the world a better place while the Avengers continued to oppose them and also kidnapped Hope so Scott declared, No More Avengers.
When Emma discovered the Avengers were hiding in Wakanda, she told Namor who later stormed the country, but is defeated by the Avengers and his portion of the Phoenix is absorbed into the other four. With her increase in telepathic powers, Emma began losing control by killing people who have harmed mutants and when Colossus and Magik lost their portions, Emma and Scott became even stronger. Emma then began exerting her dominance over the X-Men so Magneto attempted to reason with her but Emma refused to listen and threatened him. Later, Scott traveled to Utopia for Emma after being defeated by Hope and when the Avengers attacked, Scott brutally took Emma’s portion of the entity from her and killed Xavier after becoming the Dark Phoenix.
Emma is later in custody of the New Avengers until she’s later freed by Scott and Magneto as she was being transferred where she admits losing the ability to reading people’s minds while Scott and Erik have also had issues with their powers. Eventually, Emma agreed to join Scott, Erik and Illyana in the search for new mutants and was present when Scott freed several mutants. Emma also donned a new outfit in Scott’s new version of the Brotherhood.
Emma possessed the same telepathic abilities matching Charles Xavier capable of extraordinary telepathic feats but following Avx, it’s discovered she had lost her telepathic abilities after being in contact with the Phoenix Force. Emma also possesses the ability the transform her body into a flexible organic diamond form which is similar to Colossus’ organic steel form. If Emma is rendered unconscious, her body will automatically transform into its normal state and while in this form, Emma’s personality becomes more cold-hearted and also does not have access to her telepathy in this form. In her diamond form, Emma’s physical strenght is increased to lift around 2 tons and is also immune to other telepathic powers. Emma is also highly skilled in electronic theory and electronics, trained in hand-to-hand combat and also excels in astral combat.
