## History

### Origins

**Chronos**, known to the public as **Alexandra Callahan** or simply **Alex** or **Lexi Callahan** is known for being a local heroine in her city. people began calling her a “hero” as her heroine persona, Chronos. Lexi Callahan was born September 19th, 1994 to her mother, **Madline Callahan** and her father, **Liam**. Growing up Alex was about as average as the average person. She loved her siblings **Scarlett** and **Jackson**. However, one day that soon changed as she became ill with the flu. Since their parents weren't home Jax volunteered himself to drive his sisters there (As Scarlett wanted to tag along). The moment that they arrived, Jackson was hit over the head and sent to the same laboratory that Scarlett was sent to, along with 4 year old Alex. When Jackson, Lexi and Sky woke up, they were strapped into a chair and had just finished a procedure. All three of them in the same room. When the dance instructor, who was actually a scientist, came in, Scarlett resisted and tried to get out of the leather straps that she was tied in. She was screaming for help when she realized she couldn’t get out, and in one of those screams she let out a loud, sonic scream that destroyed the wall and made the scientist go absolutely deaf. Jackson realized that he had electrokinesis, and destroyed every machine in the room and destroyed the straps where he then started untying his sisters. Where Alex then got up before forming crystals out of her hand throwing them at the scientists jacket keeping him against the wall so the police could capture him. They all started running until they realized they had nowhere to go. By now, they were in some alleyway in New York where they could easily be shot. Now, if it weren’t for some super secret government agency, they would be dead.

### Ten Years Later and Joining SHIELD

While they were with that government agency, they were trained to use their powers. Since Alex had Crystal Manipulation she was mostly trying to learn how to control her abilities. Unlike her siblings she didn't know that powers had weaknesses. Lexi, she learned how to manipulate the crystals, she has yet to learn her full weaknesses. While Sky had sonic scream and sound manipulation, she was mostly trying to find her weaknesses when she sonic screamed, since it was something dangerous that could damage another person or herself. And Jackson had Electrokinesis, he learned how to manipulate electricity and use it in his will, and he also learned his limitations and weaknesses.

### Another Four Years Later

The siblings have adapted the word 'hero' into their arsenal and have started to save people with the help of SHIELD for the name of justice and everything good. The trauma had stuck with the woman as she could never forget but could only prevent this from happening to other people.

### Personality

Alexandra is the lighthearted one of the three. She has been said by Jackson to be "Ambitious and Courages" due to her having a strong desire for success and able to face and deal with danger or fear without flinching. She has said to be by her sister Scarlett as "Gregarious and Persistant" as she's temperamentally seeking and enjoying the company of others as well as stubbornly unyielding.

## Weaknesses

**Crystal Manipulation-** May be unable to create crystal, being limited to manipulating only from already existing sources.

Firing may be involuntary reaction, or released in constant stream. Users will be exhausted when too much energy is used. Users may be over-charged/wounded if too much energy is used at once. Users need control to avoid unnecessary destruction. Sound Manipulation is the perfect ability to counter Crystal Attacks as crystals can be shattered by sonic waves.

**Crystal Weaponry-** May need contact with the ground or some other source of crystal to use powers or even be effective at all. May only be able to use one kind of crystal. May not be able to overpower Transcendent Weaponry. Weapon may require a source of power such as an item.
