Hi everyone, here is the next chapter, thank you to the person who suggested it and I hope you like it. if you have a prompt leave a comment and let me know.
Prompt: Supergirl getting hit with some kind of energy attack and, similar to Livewire, it transfers powers to Alex who is nearby. She develops elemental abilities (fire, lightning, water/ice, air, earth) and Kara helps her control and learn to use each one so they can continue saving the city together.
"Supergirl look out behind you!" Alex yelled at her sister as she saw another energy-wave heading towards a group of civilians.
A new threat had made itself known in National City, a group of people that used energy-wave guns to try to empower humans.
These people claimed that everyone deserved to have superpowers like all the aliens that had come to earth.
The problem was that of course not everyone wanted to have powers, and some humans definitely shouldn't have any.
The group were forcibly giving civilians dangerous abilities, ones that had proven difficult to control by the few people who had contracted them.
Kara turned just in time to see the wave, using her body and cape as a shield to stop the wave from hitting the people.
The wave hit Supergirl, but didn't do any damage to the Girl of Steel.
Alex (who was standing close by since she had moved to protect the civilians if Supergirl couldn't get there in time) was not as lucky as her sister.
The wave of energy hit her, throwing her back a good 20 feet.
"Alex, are you ok?" Kara yelled as she raced to her sister's side to help her up.
"Yeah, yeah I'm good, let's take care of this already." Alex responded, standing up shakily.
She felt kind of strange, like a weird tingling throughout her body, but she figured it was fine.
Kara gave her a look but knew they didn't have time to argue about it, they needed to take care of the situation.
They both returned to the fight and Alex tried to ignore the growing feeling of weirdness that hadn't left since she had gotten hit.
As they fought, another energy-wave was released, and headed towards a building with people inside.
Supergirl was no where in sight, and Alex watched helplessly as the wave neared the building, threatening the lives of everyone in it.
Suddenly the wave came to a stop as it bounced off a huge wall of earth that appeared to come out of nowhere.
"What the…" Alex said, staring at the wall, she looked down at her outstretched hand and purposefully tried to ignore the fact that it looked like her hand had created the wall.
"Where did that come from?" Kara asked, appearing in the sky above Alex.
"I don't know it just popped up and- Supergirl look out!" Alex said suddenly as she saw a man come up behind her sister with another energy-wave gun.
Suddenly the man was knocked to the ground by a huge gust of wind.
Alex looked back down at her hand; she could've sworn she felt like the air came straight from her.
"Alex, did you do that?" Kara said, tentatively landing on the ground as she slowly approached her sister.
Alex looked down at her hands again, "I don't… I don't know." She said slowly.
The fight was still going on and Kara knew they still needed to help everyone else, "We need to take care of this but right now we have something bigger going on, are you good for now?"
"Yeah" Alex said slowly, "I'm good, let's finish this."
The rest of the battle progressed more normally, at least from Kara's perceptive.
Alex on the other hand, was having the strangest time of her life.
Every time she tried to fight, some strange element would erupt from her and attack whatever she was attacking.
Granted it was helpful, but she had no control over it and she almost hit the other agents and civilians.
After almost hitting a little boy with a burst of fire, she panicked and stopped fighting.
Alex wanted to help but she was terrified about what was happening to her and petrified of hurting someone.
Soon enough, Supergirl and the rest of the DEO had captured all the energy-wave guns and the criminals were arrested.
Kara realized she hadn't seen her sister since the earlier incident, so she listened for her heartbeat and went to find her.
"Hey" Kara said, coming to sit beside her sister, who was sitting down against a wall in an alley.
Alex didn't say anything.
Instead she looked away from her sister and scooted away a little bit so they weren't touching.
"What happened Alex? Please talk to me." Kara said gently, she wasn't sure what had happened with the earth wall and the gust of air, but she could take a guess considering the situation.
"I don't know for sure, but I think… I think that stupid energy-wave gave me powers, after I got hit, every time I tried to fight someone some weird thing happened. I had no control, I almost… I almost killed a kid, Kara." She said, voice breaking slightly.
She was so afraid, what if she was stuck like this forever? What if she actually did kill someone? How was she supposed to live any kind of life like this?
Alex swallowed hard, panic was rising inside of her but she was afraid to even cry if that somehow offset her strange new abilities.
"Lex, look at me." Kara called, pulling Alex from her panicked thoughts and back to reality.
"I know this is frightening, trust me I know what it's like to suddenly gain new powers, but you aren't alone, I'll be here to help you and we'll fix this."
"But what if we can't, what if I'm like this forever?" Alex asked, her voice was tiny and laced with fear.
"Then we're gonna make an even better team." Kara responded.
Alex turned to look at her sister, "I can't control these powers at all, I have no control over myself."
Kara reached her hand out and gently brushed aside some hair from her sister's eyes, "Then I'll help you learn, I have some experience in the field."
Alex smiled a little at the comment and took a deep breath.
This was going to take some getting used to, but she knew she wasn't alone, and that made all the difference.
2 days later Alex and Kara sat in the DEO training room, both girls were out of breath from several hours of training and had decided to take a little break.
In the days prior, Alex had been pricked and prodded by a whole crew of DEO scientists as they tried to understand her powers and how to reverse them.
They did have access to the energy-wave guns, so it made things a lot easier.
It was understood that Alex had four main powers, she could control the air, any water around her, bend the earth, and create fire.
The number of 'Avatar the Last Airbender' jokes that had been made since everyone realized this was astronomical.
The scientists who were working on the problem were definitely in for a challenge, but they seemed confident in their ability to fix the damage done, still it was a complicated process.
Kara had thought it would be a good idea to work with Alex on getting control of her powers, just in case things were irreversible or it took a long time to change her back.
At first it had been tough work, Alex had no idea how to cause or control her powers, and Kara didn't either.
But through a lot of work, and a little bit of arguing, Alex had gotten a pretty good handle on her new abilities.
In fact, she was kind of starting to like it.
Sparring with her sister got a lot more fun, and even though she had always been able to hold her own in a fight, she liked the idea of having more power.
Not that she needed it for herself, but a part of her felt like the new powers could help her to protect Kara and everyone else, and that was always her main goal.
She was starting to think that if they did eventually find a way to reverse her powers, she might not go through with it.
"Well you wanna try some more?" Kara said after they both caught their breath.
They had just been fighting each other without the kryptonite emitters and it had been quite the fight, ending in a tie.
"Yeah maybe but I was wondering, what would you think about me keeping the powers?" Alex said suddenly, she'd been thinking about it a lot, but she wanted to know what her sister thought.
"Woah, that would be crazy." Kara said.
She looked at Alex, making sure her sister was looking at her while she continued speaking, "But to be honest, I kind of figured you might decide to do that once you learned to control them."
"What really?" Alex said, shocked since the idea hadn't even occurred to herself until earlier that day.
"Yeah, because that's the kind of person you are, you want to help everyone you can, and even though these powers are kind of insane they would help you help others."
Alex listened carefully, everything Kara had said was true.
Sometimes she hated having someone who knew her so well.
"Well what do you think about it?" Alex asked.
"I think you don't need any superpowers to help people, but you of all people should have them since you'll use them to protect and help others. I think if you kept them you wouldn't ever regret it, but the decision is yours to make and I support you either way." Kara said.
Alex was silent, carefully thinking things through. "I think I'm gonna-" she stopped as J'onn suddenly came into the room.
"There's an emergency downtown, an alien is causing some problems, let's go." He said to both of them.
Kara looked at Alex, "Well, you ready to give this a shot?" she asked.
Alex had yet to actually go into a fight with her new powers, but what better time than the present.
"I don't know about this Kar, what if I mess up, I still don't have that good of control…"
"Alex, you've got this, besides we'll handle this like we handle everything, together." She said.
Alex took a deep breath and nodded, "Together."
