Name: Jillian "Jill" Kirke
Weight: None of your business. Ask it again, and you'll get an icy fist in the face.
Hair Color: Black (With blue dyed bang)
Eye Color: Brown
Sexual Orientation: Straight
Occupation: Student, adventurer
Marital Status: Single
Relatives: Jonathan Kirke (Father), Padma Aghdashloo-Kirke (Mother), Thomas "Tom" Kirke/Gravitar (Older Brother), Jackson "Jack" Kirke/Fireball (Twin Brother), Simone Kirke (Younger sister)
Skills: Jill is skilled in kickboxing and karate. She also is a talented writer, wanting to be a novelist one day. She and Jack have collaborated on little comic strips as children.
Powers: Jill is cryokinetic. She can create ice by decreasing the temperature of ambient water vapor in the air around her. If she needs to, she can use this ability to create ice shields and armor (One of her favorite attacks is to cover her fist in ice and punch someone with it). She can also create ice constructs that she can dissolve at will. Her powers make her immune to the effects of exposure to sub-zero temperatures, like frostbite and hypothermia. Like her brother, she is able to fly.
She has a telepathic link with her twin brother Jack, aka the hero Fireball. The two can use the link to privately communicate, and they can also use the link to find each other if separated.
Personality: Jill is known for her temper and inmpulsive nature. However, she is a kind and friendly girl when something isn't setting her off. She is a bit of an adrenaline junkie, enjoying activities like motocross racing and skateboarding. She also has a bit of a smartmouthed streak to her, enjoying taunting the villains she and Jack fight. Bringing up the villain Gravitar is a rough point for Jill, due to the crazed metahuman being her older brother.
Bio: Born and raised in New York City, Jill is the second child (She was born two minutes before Jack) of two British immigrants, a doctor named Jonathan Kirk and a scientist named Padma. The Kirke family lived the good life, but they were also a family dedicated to helping others and giving back. Jill Kirke, in contrast to her calm and quiet brother, grew into a loud, hotheaded adrenaline junkie.
At the age of 16, Jack and Jill manifested their metahuman powers. Amusingly, the hot-headed Jill gained ice abilities, and the cooler, laid-back Jack gained fire abilities. Previously, their elder brother Tom manifested gravity-manipulation abilities in a car accident. The trauma from the accident and his powers manifesting, combined with a brain injury, led him to believe that he was the king of a new race of gods destined to rule the earth.
Not long after the twins manifested their own metahuman abilities, Tom returned, donning a suit of armor and calling himself Gravitar. Gravitar tried to get Jack and Jill to join him in his campaign of world domination, but the two refused and tried to get him to get some help. Sadly, it degenerated into a fight, the twins having to use their powers to fight him off. The incident inspired the two to take up the life of the superhero and stop their mad brother.
