Bio:

Jacqueline 'Jack' Summers-Stark was born on February 28, 1996, at Xavier's School for the gifted, to Jean Grey and Tony Stark.

Whilst Tony was not informed about the birth of his child, Jean never kept the truth from Jack, because of this, from a young age, Jack idolized her father and was inspired to follow in his footsteps.

Sometime after Jack's birth, Jean fell in love with Scott Summers, eventually marrying him, he unofficially adopted Jack as his daughter, never treating her as anything but that.

Jack was very close to her mother; on Christmas, they would watch old holiday movies together as it snowed for hours without end outside.

One day, Jack was out riding her bicycle with her mother when she fell off and got her leg stuck in the bike as a car sped towards her. Her injuries and fear caused Frostbite to manifest for the first time, triggering Jack's transformation into her alter-ego. Despite her mother's protests, Jack looked into her bicycle mirror and saw her transformation, causing her to scream in terror. Jack would repress this memory and Frostbite for years.

As the years went on, Jack became to resent Tony, loosing her admiration for him. Feeling abandoned by him despite knowing that he has no idea she existed. To try and remedy this, Jack wrote to Tony telling him about her, including a photo of Tony and Jean. She never heard back from him, increasing her resentment for him.

When she was 14 years old, Jack's powers began to fully manifest, this occurred while she was taking a shower, her hair turned pale blonde; she promptly cut off the altered hair to hide her powers. Jean eventually discovered this and scolded Jack, telling her to embrace who she is, that she shouldn't be afraid of what she can do.

Personality:

Jack is generally a very compassionate and caring woman and is determined to help others.

Jack is also seen to be somewhat "guarded" of her personal life, not revealing anything about her unless to someone she trusts completely.

Though not as prominent as her other traits, Jack has a somewhat flirtatious side to her personality. Often when flustered or uninhibited by the effects of alcohol she can become silly and frazzled.

Jack is shown to be extremely naïve when it comes to men (with a pretty face, huge muscles, and shining teeth) and trust.

Since Jack has been developing cryogenesis/cryokinesis abilities she has been terrified of becoming a 'villain'. However, Jack is still sane enough to realize this but is only more horrified at her increasing inability to manage her emotions. However, her desire to retain her humanity and her biology changing to make her more "cold", seems to be causing Jack to develop dissociative identity disorder.

Pairing: Pietro Maximoff

Powers

"Persistent subthermal homeostasis with, uh, involuntary gelid substantiation. She gets cold and freezes stuff." — Fury

Cryogenic physiology: Inheriting mutated genes from her mother, Jack gained cryogenic powers and physiology. They remained dormant for 14 years (apart from a few brief episodes during her childhood), as several tests never showed signs of a mutated gene. Reaching puberty, her powers started to fully manifest.

Accelerated healing factor: While accessing her powers, Jack's metabolic rate is augmented to offset cold tissue destruction, allowing her endure more grievous injuries and likewise heal much faster than even a super-soldier, though foreign matter must first be taken out to not impede the healing. However, her healing powers only work when her Frostbite side takes over.

Superhuman durability:| Jack has shown remarkable durability, able to withstand multiple punches and cuts, and still keep fighting her without losing consciousness, and was able to quickly get up after being thrown against a wall.

Transformation: After Jack and Frostbite decided to be just one, Jack became able to transform into Frostbite and vice-versa; Jack's transformation affects her physical appearance, as it turns her hair white/grey and changes her eye color to an icy blue.

Energy absorption/Cryokinesis: Jack's powers work by absorbing all existing heat around her, thereby reducing the temperature and to freeze targets well-below negative 370 degrees. Furthermore, her powers can reach such low levels that they can completely negate enhanced healing power and alternatively neutralize accelerated decomposing. Jack can create various ice structures with ease, such as large bulletproof shields that can withstand point-blank automatic rifle rounds as well as launch upon manifestation sharp projectiles in rapid succession. Jack can conjure icy blades around her arms as means of transportation by producing icy waves of such propulsive strength, with one hand behind her, to propel herself forth across an ice slide she forms before her with her other hand, similar to Iron Man's energy-based propulsion. Her powers can also affect the weather around her, dropping the climate of the area and cause it to snow. A tell-tale sign of Jack accessing her powers is producing icy mist from her hands.

Freezing kiss: Jack is able to near-instantly freeze people through a kiss, allowing her powers to enter her victims' bodies and freeze them from the inside.

Cryokinetic constructs: Jack can create various structures and weapons made out of ice, of which she can utilize during a fight.

Ice spike projection: Jack is able to create spikes out of ice in order to use in combat as projectiles, daggers, swords, and claws.

Cryokinetic surfing: Jack can freeze particles around her, utilizing it to create an ice slide which she can use to get around much faster. She can also use her cryogenic powers to continuously propel her on the slide to increase her speed by placing one hand behind her to push herself along. Jack can also extend the slide while propelling herself along by freezing the particles in front of her when she is on the ice slide.

Freezing breath: Jack is able to create a fog with her breath.

Cold immunity: An added benefit to her powers, Jack also exhibits high resistance to frigid temperatures. She is shown to be able to hold the ice constructs she manifests with little trouble.

Mental communication: Jack and Frostbite are able to talk to each other whenever one of them is in control.

Remote cryokinesis: While transforming into Frostbite, Jack can freeze objects without physical contact with the object itself. This ability is seemingly passive, meaning that Frostbite isn't willingly controlling it.

Abilities:

Genius-level intellect/Master scientist: Jack is extraordinarily intelligent.
