Chapter Summary: Prompt by WritersBlock039: Some time in Season 4, Kara is captured by the Children of Liberty, and Lockwood himself is about to execute her on live TV. In a fit of desperation, Alex reaches out to Earth-1 for help. Surprisingly, it's not Team Flash or Team Arrow that responds - it's the Legends (Sara, Ray, Nate, Mick, Zari, Constantine, and Nora). The Legends show Lockwood and his Children of Liberty exactly what happens when their super puppy is messed with - featuring overprotective Ray, Nate, Mick, and Zari, magical badasses Constantine and Nora, and if possible, a SuperCanary romance (SaraxKara).

*I made a few changes in the episode they fill the air with kryptonite, it wasn't good for this story hahaha.

.

Kara flew high on the sky, feeling confident. She was about to find the responsible for the attacks on the aliens when she felt something hitting hard her stomach. It was a terrible familiar pain that took over her entire body. She felt weak, losing her speed and the ability to keep herself on the air.

She started to fall.

She was sure she was going to die.

A huge net was ready to catch her, but she couldn't tell what it kept her body from hitting the ground, she passed out a few seconds before falling on the thing.

- YES! – A deep voice yelled from distance, coming closer slowly.

- Be careful! She might wake up... - Another voice said it

- I doubt it! It was a huge amount of kryptonite we shot her. Boss will be happy with us!

- Let's take her to him!

They grabbed Kara's body evolved with the net and put it inside a black van.

Meanwhile on the DEO, Alex walked from one side to the other, feeling impatient. She had no answer from Kara; it looked like her comms were off. Kara never turned them off, and she could feel that something was really wrong. J'onn and Brainy arrived, looking worried at her.

- Alex what happened? – J'onn asked

- I don't know... I need you to use your telepathy. Kara is not answering her comms. Please, she should be back by now...

- I can help you with that... - Brainy said as he closed his eyes and focused – I'm hacking her comms and yes, they are off...

- How... - Alex said but was interrupted by J'onn.

- I'm not sensing her at all... Brainy, give us...

He was about to ask Brainy to hurry up on finding Kara's location when a creepy image appeared on their TV.

- Someone's hacking the signal... - Brainy said, trying to find out what was going on, until a familiar face showed up on the screen.

Far away from there, Kara felt her whole body hurting. She couldn't find strength to open her eyes and understand what in Rao's name was going on.

- Wake up... - She heard someone talking to her in a low voice.

As she opened her eyes, she saw a masked guy. It was beyond creepy. He had armor on and she couldn't even use her x ray vision because she was too weak, and the little she tried to, she could tell it was all made of lead.

- Who... - She tried to speak – are... you?

- I'm the one who's going to free this planet from your kind!

- What?

She felt confused until she felt a punch hitting her right cheek. Another one came to her mouth and she could feel the blood, spitting on the floor.

- Why are...

- Why am I doing this? – He completed her sentence for her. – Because I can. You are a disgrace for this planet, a monster and God knows what evil you can cause to our Earth...

- I'm not evil... I help...

- You help people? Convenient... I'm done with you destroying our city, people are dying right under your noses and you just make everything worse. This planet is for humans only, it's about time someone put you in your place, far away from here!

At the DEO, Alex looked terrified at the screen. She recognized Kara in the background, all hurt, bleeding and looking like hell. There was an armored guy in front of the camera, talking nonsense about aliens not belonging.

- I need to do something! – Alex said as she looked at Brainy and J'onn.

- We still don't have her location... I don't know how we can help her now...

- I know people who can help her...

- Who? – Brainy looked confused at Alex as she ran away.

- I'll borrow a bike from DEO – Alex yelled as she ran.

J'onn and Brainy kept starring at her like she was a mad person. Alex ran like hell as soon as she got her hands on that bike and In a few minutes she was at Kara's place. She got inside with her key, looking all over for that tiny object until she finally found it on Kara's bedroom.

- I hope this works...

She had a few tries with that device, trying to reach anyone from Earth 1, until she managed. It was her only available option.

At CatCo, James, Lena and the entire crew watched the creepy guy talking on the TV. They were all shocked, not believing their eyes.

- Is he...? – Lena tried to ask something, but couldn't say anything

- Going to execute Supergirl on live TV? – James said, not looking away from TV – It looks like it...

- Where's Superman? – She asked as she looked at James

- Kara told me he was visiting Argo... We have no way of talking to him...

- I can't believe it! – Lena said covering her mouth with her both hands.

Agent of Liberty looked at the camera, feeling a weird satisfaction about having the most powerful alien under his power. He waited years for this moment, and now he would finally have his revenge.

- World, you must know: I do this for our own good. It's about time we take this Earth back from aliens... And now, you'll see firsthand how Supergirl is a fake. You put your lives on her hands like she was your savior... She's not! And I can prove it!

He held a huge knife on his hand, ready to sink it in her stomach. Kara couldn't do anything; she was beyond weak.

Everyone at CatCo looked shocked, people at the DEO tried not to look as Agent of Liberty stabbed Kara.

- What the...

They heard the lunatic saying and looked at the TV. He tried to use the knife against Kara, but something was keeping him from doing it. Suddenly, something like fire hit the camera and the signal went off. Everyone started freaking out, trying to understand and find out if Supergirl was ok.

Lockwood was caught by surprise when an armored figure grew in front of his eyes, punching him in the face.

- That's no way of treating a lady, Mr. Crazy! – Ray Palmer said in his Atom suit, coming back to his regular size.

Mick toasted the camera with his fire gun, feeling deeply satisfied with himself. Amaya came through the breach, using her totem, channeling the strength of a gorilla and holding Lockwood with his arms behind his back. Nate ran and grabbed his gun, destroying it on his steel form while Sara Lance came at least, hitting Lockwood with all she got.

- So, you hate aliens... What do you think about people from another Earth? – She said, nodding for Amaya to let him go.

Amaya ran and grabbed Kara along with Nate.

- The Sun... I need... - Kara tried to say but still felt dizzy.

- Take her to the Sun, Mick and I will take care of this scumbag! – Sara ordered as she looked to that creepy guy with thirst for blood inside of her.

Lockwood stood up, taking his mask off. He looked confused at Sara.

- Who the hell are you?

- Let me tell you a story...

She said smiling viciously as she twisted her body, hitting a high kick on his chin.

- I'm a trained assassin! – She said escalating him until she reached his shoulders, her legs locking on his neck as she twisted her body, throwing the guy on the ground. – I used to skin guys like you alive!

- What?

- I'm not from around, you see... - She said as she blocked a punch from him, making him roll on the ground, giving him a punch on the nose. – So whatever I do to you, I get a free pass!

- You're crazy!

- You have no idea! You just messed with the wrong alien!

Sara knocked him out, smiling at the scene. She missed this rush, the satisfaction on having someone shitting their pants afraid of her.

Amaya, Nate and Ray carried Kara outside and she turned her comms on. It took only a few seconds until J'onn and Brainy appeared.

- I'm so sorry we're late; it was really hard to hack those comms... There was something blocking us from finding here... - Brainy said as he noticed the shocked looks from those strangers.

- We take it from here...

- No way! We go along wherever Kara's going! – Amaya said ready to fight whoever she had to.

J'onn entered the place and introduced himself to Sara, holding Lockwood by his arm.

- Thank you for your help!

- We came as soon as Alex sent us the message!

- I appreciate it. If it weren't for you, Kara wouldn't be alive now...

- Anything for the Girl of Steel! – Sara smiled at J'onn and looked at Lockwood. – Do you mind if I talk to him?

- As soon as he is locked at the DEO, you can.

- Thank you!

Kara was taken to DEO'S med bay as soon as they got to the DEO. Alex ran to help, in tears. She hugged all Legends, one by one, thanking them and ran away to turn on the Sun lamps so Kara could fully recover.

- We are truly thankful, strangers! – Brainy said as he looked at them.

- Kara's like our sister! – Ray said, looking around impressed – What a cool place you guys have here!

- Enough small talk, I want to talk to that bastard! – Sara said as she looked serious at J'onn.

J'onn nodded with his head and took Sara to the cell Lockwood was in. As soon as she got inside the room, she nodded at J'onn and he left them alone.

It was a big room, the cell was in a corner and it looked really strong. Lockwood looked at her from inside of it, smiling sarcastically.

- You usually like getting beaten by a woman, I see... - Sara said as she took a few steps closer.

- I don't know who you are or where you came from... You just have no idea who I am...

- You have no idea who I am! – Sara looked at him with a cold look that probably could freeze the entire room. – Like I said, you hate aliens...

- They don't belong...

- Bullshit! Do you know that there's an entire multiverse out there?

- What?

- Yes. Multiple Earths, multiple versions of ourselves... I happen to be your worst nightmare from another Earth. I did some research... My version of this Earth is dead... So I can do whatever I want with you, no one will know.

Lockwood looked at her more serious this time. Something told him she wasn't lying, by the way she looked at him.

- I also happen to captain a time travel ship... Are you aware that I can leave you to be eaten by dinosaurs? That I can leave you in the middle of the pre historical times? And no one would know what happened to you.

- Are you joking?

- I'm dead serious! I guess I'll take you for a ride later... It's something you'll never forget; it will terrify your dreams forever. I know how to scare a scum like you!

- What do you want?

- For you to pay!

Sara pressed a button on the wall and as soon as the cell opened, she jumped Lockwood, pressing his neck strongly as she dropped him on the ground.

- You tried to kill someone I care about! I used to torture people like you for sport...

- You're...killing...me...

- I know! I was trained by the devil so can you imagine all the things I will do to you before you die?

- SARA, STOP!

Kara came inside the room, walking slowly and looking at Sara with pleading eyes.

- Kara, this jerk tortured you and tried to kill you.

- I know. But we need to be better than him! You are better than him!

- I'm not! You barely know me!

- What I know is enough for me to see you're a hero and not a killer... Not anymore. He will pay for his crimes, the right way... Please...

That look on Kara's face hit something deep in Sara. She dropped the guy on the floor and got out of his cell, closing it again. She closed her eyes, taking deep breaths. It was like something took over her and made her thirsty for Lockwood's blood. Her lust came back so fast, she felt dizzy. It took a while for her to recover and recover her conscience. She felt a hand on her hand, pressing it slightly. She opened her eyes and looked at Kara.

- I knew you could do it...

- I barely could...

Sara stormed out of the room. Kara gave a last look at Lockwood as he looked full of hate in his eyes.

- I forgive you, just so you know it... - She said and left the room.

Kara used her x ray vision and found Sara inside a room, alone. She knocked and entered. Sara looked at Kara, clearly tormented with something.

- I guess this whole thing messed with me more than I thought it had... - Sara said – I'm sorry I almost killed him... I guess my blood lust came back...

- I don't think it did...

- How do you know?

- Because when we met, I saw you fight with all your power to do good. And you didn't cross the line... Even if they were Nazis...

Sara looked at Kara, thinking about everything she was hearing. She felt something weird inside of her, she wasn't used with people trying to see the best of her and ignoring her assassin past. Kara truly was something else.

- I guess you're right... I just... It's hard to explain, not even I understand it...

- Well, thank you for coming and helping me...

- Like I said to J'onn, anything for the Girl of Steel.

Kara blushed, smiling at Sara. She appreciated a lot her friends, even if they were from another universe. She knew now she could always count on them. Sara approached a few steps, looking her deep in the eyes.

- I'm sorry again; you saw my worst side...

- It's not your worst... Every part of us are beautiful, we just need to see it.

Sara smiled, coming closer and giving Kara a small peck on her lips. They looked at each other and Sara stepped away.

- I'm sorry; I need to go back now... Call us if you need anything, Danvers!

Sara stormed away, leaving Kara looking shocked at the floor. She wasn't expected for that at all, but she had surprisingly nothing against it.
