Prologue: Origins

Earth 2

Krypton

Like in many other universes, Krypton was doomed to explode, so Zor-El had planned to send his daughter, Kara, to safety, with his brother's son, Kal-El, who was still a baby the day of the explosion, barely three years younger than Kara. Alura Zor-El, Zor-El's wife, a judge on Krypton, had accepted to keep this research a secret from the council, while Zor, Jor, and Lara, Jor's wife, were working on the pods.

One night, a few days after the ships were built, Krypton's doom started, with earthquakes destroying the entire planet, and storms ravaging every city on the planet. That night, the House of El building was shacking, and Alura was woken up by her three-year-old daughter's cries.

Alura went to take her daughter, and with her husband, they went to the launching bay. By the time they arrived, Kal's pod was already being launched into space. After kissing goodbye, Alura pushed the button that placed the cockpit on the ship, and got ready to launch.

However, something went wrong, and the planet exploded before Kara's ship could ever get out of the planet's gravitational field, sending a shockwave that pushed the ship right into the Phantom Zone, a region in space where time doesn't pass.

Earth

She spent twenty years in that timeless void, until she was woken up, by a twenty-year-old Kal-El who took the cockpit off from the ship, revealing his still-three-year old cousin.

While Kara was in the Phantom Zone, Kal-El, known to the world as the reporter Clark Kent, had revealed himself as Superman.

Kal helped Kara get out, and flew to a big house, where a man and woman were standing, a soft smile on their faces.

While Clark was trying to control his abilities, the man, Harrison Wells and his wife, Tess Morgan, had helped Clark a lot, and when he contacted the scientists for help with his cousin, who would probably need help with her powers as well, both Wells' accepted. Kara then became a part of the family, and going by the alias of Kara Wells.

So, Clark dropped Kara to the Wells household, and went back to Metropolis. Harry and Tess already had a three-year-old daughter named Jesse, and over the years the two girls bonded, and with a genius mother and dad, they had become very smart, always together, and competing for top of their class.

Sadly, when the two were about nine years old, Tess died in an accident, claiming her life, and the life of the drunk driver that crashed in her car.

While going to school, and learning English, Harry taught Kara how to use her powers, even using the research he did with Clark, about Kryptonian physiology, and helped Kara learn everything she needed to know.

At age 15, they both graduated from High School, and then went to college, Jesse taking five majors, including bio-chemistry, and Kara also taking five majors: physics, chemistry, mechanical engineering, chemical engineering and bioengineering, both as smart as their father, maybe more, as he would say, himself.

Since she didn't need her powers, she didn't want to save the world like her cousin did, at least not in the same way, she wanted to do it like her father, change the world, with science. Studying all the kinds of kryptonite that had fallen to Earth, Harry found pure gold kryptonite, that if kryptonians are in contact with it, they lose their powers permanently, after long exposers. When Kara was ten, Harry found a way to get gold kryptonite, and two years later, created some sort of tanning bed, but instead of solar radiation, it showers gold kryptonite radiation in the user. After a few hours of exposer for five days, Kara had completely lost her powers. She was completely human, and did not need the lead glasses Clark wore to keep his x-ray vision in check. Since she didn't have her powers, Clark gave his cousin the kryptonian armor from his Fortress of Solitude, in case the blond changed her mind about saving people, even without her powers. Ever since that day, the blond had tinkered with it, and had added a few things, even making sure she could use its features even without the suit, making a glove with repulsors on them. She could wear bracelets on her wrists, and activate the gloves if needed.
