Frost Sisters

The **Frost Sisters**, also known as the **Three-in-One**, are a set of telepathic triplets whose abilities are greatest when in close physical proximity of each other, as they share a hive mind-like connection.

## History

The Frost sisters are genetically engineered Mutant clones and were originally a set of Quintuplets. A lab funded by Creed financial created and used them to commit atrocious acts, as a precaution only three of the sisters would be used at a time while the other two were held back to be used as collateral. One day, after using their powers to interrogate a prisoner, three of the sisters, Esme, Sophie and Phoebe used their powers to force the guards to kill the doctor and then each other, in the belief that they could save the two left behind, Mindee and Celeste. However they were too late and Mindee and Celeste were killed by their inhibitor collars, turning the Quintuplets into Triplets. Somehow the remaining sisters came into the employ of the Hellfire Club.

Two months prior to eXploited, they infiltrated a rally for Senator Montez. Esme was undercover as his assistant named Stacy. After she talked with Senator Montez, Esme was telepathically warned by Sophie and Phoebe that Sentinel Services had arrived to capture them. They told Esme to run and escape as they were being taken by Sentinel Services. While Esme escaped, her sisters telepathically told her to find them. Sophie and Phoebe were then taken and imprisoned at a facility. Despite her immense power, Esme knew she couldn't mastermind a prison break on her own, so she had her unknowing allies plan and lead an attack on Trask Industries after informing them of the Strucker parents so called deception with everyone realizing that it was too late once they found Esme manipulated all of them.

## Throughout the Series

### Season 1

In *"Exploited"*, the Frost Sisters are reunited after casually massacring several Sentinel Services agents during a prisoner transfer from Trask Industries. With more Sentinel Services agents approaching, Esme, Sophie and Phoebe eyes glow blue as they instruct the leading officer to fire on his fellow agents, killing them all. As Andy, Lauren, Clarice and the other mutant prisoners exit the transport vehicle, Esme, Sophie and Phoebe speak in unison. "Time to go boys and girls. The fun's just starting."

In *"3 X 1"*, Esme, Sophie and Phoebe recount the Trask escape with William, an associate of theirs. The alarms were going off. People were coming. They went one way while the Mutant Underground went another. They took the Struckers without so much as a thank you, the girls add. And in the 2 days since that, they've had no interaction with the Underground, who felt used. So Esme, Sophie and Phoebe wanted to give them some space since their parting moment was heated, to say the least. William is displeased with the mess they left at the Trask lab. But as Esme points out, they barely got out of their alive. William explains that he was recruited to rebuild the Hellfire Club with them. So activities like his, such as taking down a hedge fund are essential, while their transgressions will only make things more difficult, like their killing of a dozen Sentinel Services agents. They made a lot of noise, yet the Hound program is stronger than ever. So they need to act quickly and they'll need the Underground's help.

Esme, Sophie and Phoebe arrive at the Underground station unannounced. They've come peacefully as they only desire to talk about the Hound program, which is expanding, and they want the Underground's help in taking it down. However, Marcos and Reed are still upset that Esme used and lied to them. Admittedly, Esme mislead them, but she also saved their children and her family. The ends justify the means as far as she is concerned. As for why they need the Underground's help despite their own powers being so great, Sentinel Services knows what they look like. So they can't take them on by themselves. They have information about Dr. Campbell's plans and resources to share. Meanwhile, the Underground has the muscle. While Caitlin and Marcos refuse to even consider an alliance of any kind, John seems more willing though he does kick them out after hearing what they have to offer.

One of the Frost Sisters visits Andy at the Fairburn station after the Struckers left the Underground. When Andy asks which sister he is talking to, she replies that it doesn't matter much as they're essentially Three-in-One. She heard about the Struckers running off from Atlanta. Andy explains that his parents wanted to protect him and his sister. However, Andy is hardly someone who needs protecting. She tells him to speak to his parents as "Andrew Von Strucker" if he wants to be taken seriously. He's surprised that she knows about his family's history. She claims that she knows all about the Strucker family and who Andy is meant to be. She tells Andy that he's not a child anymore and that they need him most of all.

Esme, Sophie and Phoebe rescue the Underground as they are under attack by Sentinel Services and their Hounds at the Fairburn station. The Hounds in question are wearing a manacle that allows them to combine abilities, making them even more dangerous and powerful. As Thunderbird, Eclipse, Polaris, Blink, Lauren, Wes, Andy, Reed and Caitlin quietly move throughout the woods, the Sister telepathically speak to Andy and guide them out the woods. The Underground makes it out to the road where they find Esme, Sophie and Phoebe waiting with escape vehicles.

When Marcos questions how they even found them in Fairburn, the Sisters claim that they have sources. The Hounds that attacked them is what the Sisters tried to warn the Underground about. But it was only the start. It's going to get worse, which is why they need the Underground's help to take down Campbell and Trask.

The Frost Sisters reconvene with William, who is irate. He has been taking calls for hours. The inner circle is angry with their stunt. The sisters wonder if the inner circle had a better idea. Because if they did, they could've shared it instead of hiding behind their screens and chessboard. Esme, Sophie and Phoebe risked a lot of lives as they were responsible for tipping off Sentinel Services to the Fairburn station. The Frost sisters defend their actions by reasoning that someone times you have to sacrifice a few pawns if you want to win. The Underground needed to understand what they are all up against. It would seem that their stunt went exactly as planned as the Underground has agreed to the alliance.

In *"eXtraction"*, the Frost Sisters and the Mutant Underground discuss a plan to stop the Hound program. However, before starting, Marcos makes one thing clear, that their being there, doesn't make them friends. Esme, Sophie and Phoebe know this, and then go onto explain that they're dealing with a secret program that must be stopped as soon as possible as their sources have informed them that Dr. Campbell is working his political connection to take the program International. Their best chance to stop him will be at the Humanity Today Summit in Charlotte tomorrow, where major anti mutant politicians, business heads and Purifiers will be present. The Frost Sisters want to kidnap Campbell to stop the program. When Clarice opposes the idea, the Sisters claim that they know all about her criminal past and "old friends", something she had not shared with the Underground.

Esme, Sophie, Phoebe, John, Lorna, Marcos and Clarice arrive at a very large and expensive looking safe house in Charlotte. Clarice notes that it looks "boujee", so the Sisters sarcastically offer to accommodate by bringing in mold and smashing holes in the floor. Esme then sees them inside while Sophie and Phoebe remain outside.

The Frost Sister and the Underground plan to kidnap Franklin Bennett, a big fundraiser for anti-mutant causes. He attends the Humanity Today Summit every year. If they're with him, they get past the gate. After Esme, John, Lorna, Marcos and Clarice intercept Bennett's route and bring him back to the safe house, the Frost Sisters handcuff him to a chair and force him to make a phone call to the Humanity Today Summit. Their eyes glow blue as they take over Bennett's mind and force him to make changes to his security detail. He then tells the Frost Sisters that they will be tracked down and exterminated. They don't even deserve to breathe the same air as human beings as far as he is concerned. Since he doesn't want to breathe the same air as them, the Frost Sisters make him hold his breathe. They can see inside his mind. They see the twisted videos he watches of mutants being tortured. They can feel the hate that he harbors. Clarice enters the den with the others just behind her. She brings a stop to their torture of Bennett.

Afterward, the mutants infiltrate the Summit. They get pass the front gate as Bennett's security detail. The second Senator Montez's speech is over, Polaris will knock out the frequencies for phones and walkies. Eclipse and the others are going to need to hurry because once communication goes down, the area is going to be crawling with security. Some time later, Sophie and Phoebe dump Bennett while Polaris and Esme sit in the SUV.

In *"X-roads"*, the Frost Sisters discover that Campbell and Montez filed a flight plan for Washington after they got away at the Summit. Sophie and Phoebe take Polaris to handle the matter. Whiling driving to the airport to intercept Campbell and Montez, Sophie and Phoebe tell Polaris that it was noble of her to keep her friends out of it. But sooner or later, her friends will join them. Polaris doubts it since the Underground means everything to John and Marcos. The Frost Sisters explain that the Hellfire Club protected mutants once as well, which is why they're trying to rebuild it. They know what she's thinking, but Polaris has to remember that Marcos loves her and that he'll come around. Polaris then tells them to stay out of her head.

Sophie and Phoebe arrive at the airport with Polaris. They question if she's sure that she can go through with it. Polaris assures them that she's capable of doing what's needed. She then tells the Frost Sisters to leave as she doesn't want her friends to think that she's doing it for them.

## Members

* Esme Frost
* Phoebe Frost
* Sophie Frost

* Celeste Frost †

## Physical Appearance

The sisters are completely identical, they are young Caucasian women with light skin, dirty blonde hair and blue eyes. When they use their telepathic abilities, their eyes glow with a bright blue hue, and glow even more when acting under their hive mind. They also possess the tendency to have matching hairstyles and outfits, even down to the accessories, virtually making it impossible to tell one from the other.

## Abilities and Skills

* **Telepathic Hive Mind:** The sisters share a linked hive mind, which allows them to share thoughts, communicate mentally and maintain a continuous telepathic connection over great distances. The link is strongest when they are in close physical proximity, and their collective mind also allows for increased telepathic power and shared intellect. When the girls use their telepathy, their eyes glow bright blue, and they glow even more when acting under the hive mind.
	+ **Telepathy:** The sisters possess the ability to read minds and project their thoughts to others. They are able to analyze people's memories and influence minds, as seen when Esme implanted a vivid nightmare into Polaris' mind while she slept. Though they individually possess their own telepathy, their telepathic abilities are greater when the girls join together.
	+ **Empathy:** The sisters possess limited emphatic abilities, as Esme could read Chloe Tans' emotions, sensing a lot of need and pain.
	+ **Mind Control:** The sisters have shown the ability to control multiple people’s minds at the same time, as demonstrated when they forced several Sentinel Services agents to kill both their fellow agents and themselves. However, the target must be taken by surprise and unaware of the effect.
	+ **Pain Inducement:** The sisters can induce mental pain inside people’s minds, as shown when they rendered two Sentinel Service agents writhing on the ground, clutching at their heads in pain.
	+ **Psychosomatic Symptoms Inducement**: The sisters have the ability to influence the minds of others to produce a series of illusory psychosomatic actions, that cause the body to react as if it were actually physically experiencing it; for example, they have shown to be able to induce an interruption of the respiratory tract by telling their victim to "stop breathing".

## Trivia

* In the comics, they are known as the Stepford Cuckoos, telepathic quintuplets and part of a series of clones of Emma Frost. The clones were created by the Weapon Plus program *(the same program that grafted adamantium to Wolverine's skeletal structure and gave Captain America his superhuman abilities)*. The project was code-named **Weapon XIV**, and the goal was to create thousands of telepathic clones of Emma Frost *(one of the most powerful telepaths on the planet)* that, when combining their telepathic powers into a hive-mind, would be capable of killing every mutant on the planet. Five of the clones were sent to infiltrate the Xavier Institute, to both gain the X-Men's trust and hone their telepathic abilities, and there, those five clones *(Esme, Celeste, Phoebe, Irma and Sophie)* took on the code-name the **Five-In-One** or, as they were more commonly referred to as, **the Stepford Cuckoos**. Sometime after their initial introduction, Esme Cuckoo had ingested the mutant drug Kick *(which was coincidentally mentioned in the series, in the episode Esme was first introduced in)* to boost her telepathic abilities, and that was ultimately one of the contributing factors to her eventual death at the hands of Xorn. Esme had also influenced her sister, Sophie, to partake in the drug to stop a riot at the Xavier Institute, which led to her death due to overdose. After those events, with only three sisters remaining, the Five-In-One became known as the **Three-In-One**.
	+ While in the comics they are almost always referred to as the *Stepford Cuckoos*, in the series they are collectively called the **Frost Sisters**. Also in the comics, their last name is **Cuckoo**, while in the series it is **Frost**.
		- In the episode 3 X 1, after stating that their last name is Frost, Sage continues on saying that the sisters often use new aliases to maintain a degree of anonymity. She also says that when Phoebe and Sophie were arrested, they gave their last name as *Cuckoo*, joking that they probably said that to annoy the authorities.
	+ The moniker *The Stepford Cuckoos* is derived from a combination of The Stepford Wives and *The Midwich Cuckoos*, which are two psychological, science-fiction thriller novels.
		- During the limited comic book series *X-Men: Phoenix Warsong*, the Phoenix Force implies that their last name, Cuckoo, is actually a clever code. The cuckoo bird lays its eggs in another bird's nest, who then tends to the eggs until they hatch. This refers to Dr. John Sublime *(the overseer of Weapon Plus)* placing his creations, the Stepford Cuckoos, in the X-Men's *nest*, the Xavier Institute, to be trained in using their telepathic abilities.
* Skyler Samuels revealed through an Instagram livestream that Esme serves as the peacekeeper between Sophie and Phoebe, establishing her as the "Ego" in their Freudian Trio.
* In 3 X 1 it was stated by Doctor Campbell that Sophie and Phoebe were experimented on after they were brought to him.
