A/N: So, this is just an idea that popped into my head. Fair warning, this story contains a Clark/Kara pairing. Don't like, don't read.

Legion of Superheroes HQ-The 31st Century

"Kara! Kara, wake up! NOW!"

The blonde opened her eyes, feeling the ground shake beneath her. She stood up and threw on her uniform, modeled after her cousin's original design. However, there was no mistaking that this outfit was made for war. Gone were the skirts and crop tops she used to wear. Instead she wore a blue suit of armor designed by Clark and herself after Darksied returned and almost killed her. She touched a scar on her abdomen, a reminder of the blast of his omega beams that had torn into her. She had been lucky not to die that day. They both had been. She shut her eyes, remembering how Clark had taken the brunt of the blast, leaving him with a scar across his chest reminiscent of the one Jor-El had given him when he rebelled back in high school. Or so Clark had told her as Braniac 5 had finished fixing her wound. Her cousin had refused treatment until her own wound had been seen to.

Stubborn, lovable man. She thought as she opened the door of her quarter's and ran to the main control room.

"Rokk, what in Rao's name is-"

"Rao will not be able to help you child."

"Darksied. CLARK?!" She screamed, her anger turning to terror as the gray-skinned demigod threw her cousin at her feet. He coughed, blood escaping his mouth. She didn't need to use her x-ray vision to tell her how badly beaten he was. She could hear his struggle for every breath, see the bruises on his body and his clearly broken left arm hanging at his side. All around them, their fellow Legionairre's lay dead or dying. Rokk had been stabbed through the heart by a Parademon. Imra's head lay not five feet away, decapitated by Steppenwolf, who stood by his Master's side. Garth had been killed by Lashina, the smiling Fury finally releasing her whip from around his neck and allowing his body to fall to the floor. Timber Wolf had been beaten bloody by Kaliback. Triplicate Girl had been murdered by Dessad, her bodies still spasming with electricity. And beside Dessad stood the reason they had been unprepared for this attack. Braniac 5 stood next to the mad inventor, looking completely motionless. A puppet on his master's string.

"I'm going to kill you. I swear to you I am going to kill you." Kara said quietly, eyes turning red with hate as she glared at Darksied.

"Unlikely. He was the only true threat to my rule. Your so-called Legion is at an end, and you face an army. You cannot win. But out of respect for my enemy, I will allow you a moment to say goodbye before you kneel."

Kara looked down at Clark, her red eyes returning to their usual blue as she knelt down beside him.

"Kal. Kal, look at me."

"Kara." He said so softly it was barely audible, even to her ears.

"I'm here. I'm right here." She said, squeezing his hand and fighting back tears.

"Legion-"

"Dead. They're all dead. Dessad got Brainiac and ambushed us while you were fighting Darksied."

She cursed herself for sleeping. True, she hadn't slept in nearly three weeks, but if she had been awake maybe this wouldn't have happened. Maybe Clark wouldn't be dying in her arms.

"Listen to…"

"Listen to what Clark? Talk to me. Stay with me."

"Ring. Use the ring." He said, pressing something into her palm. She didn't need to look down to know what it was. His Legion flight ring. The one his friend's had given to him all those years ago. She wanted to ask how he had it, given that the other's had been destroyed in another attack on Legion HQ a year previously. But she knew there wouldn't be time.

"Pre...programmed. Just go." He said, and she shook her head, a tear rolling down her cheek.

"I…"

"Kara...Please."

She nodded, squeezing his hand and leaning down to kiss his lips.

"Just promise...be patient...was stubborn fool. Love…"

He gasped, and squeezed her hand. Then his eyes flickered closed.

Clark Kent, Superman, Earth's greatest champion was dead.

Kara wanted to scream, to rage, to attack the monster that had taken the man she loved from her. However, there wasn't time for that. Instead, she slipped on the ring and disappeared in a flash of light. The last thing she heard was Darksied's scream of rage.

Kara looked around her, smiling as she saw that she was standing on the top of the windmill in Smallville. She had been up there several times with Clark. It was actually where he took her on their first date when she came back in 2017 to console him after Lois's death. She had meant to only come back for a couple days to make sure he was okay, and then a few days had turned into a few months. Then the incident as Clark referred to it had happened, allowing Kara to act on the feelings that she had held for so long. After the incident they had talked, really talked. Then one night, Clark had brought her here, and they had dinner at the top of the ladder. Their first official date.

Kara smiled and shook her head. She could reminisce later. There was work to be done.

Starting with her wardrobe. Her armor would make her stand out like a sore thumb, and she doubted it would endear Clark to her. If he even knew her. She still didn't know what the date was.

Kara flew into the air, flying to Metropolis in mere moments. She flew into a department store so fast that she wouldn't be seen by the cashier behind the counter, making a mental note of the prices so she could come back and leave money for her purchases later. Then she did the same at a nearby newsstand, stopping on the roof of a nearby building, having changed her clothes in midflight. She now wore the outfit she had worn when she and Clark had first met. A white t-shirt and a pair of jean shorts with boots on her feet. Her armor was now tucked away in a bag she had grabbed from the department store. Perhaps it wasn't the most secure location, but it would do for a moment. Then she looked at the date, reading it twice just to be sure.

March 3rd, 2004.

"Well Clark, I don't know why you sent me back so far, but at least I know where to find you." She said quietly, bending her knees and flying into the air. She had one more stop to make before she went and introduced herself to Clark.

Kent Farm

"Alicia NO!" Clark yelled, seeing his girlfriend disappear in a green haze, even as the bullet from Dr. Lamb's gun came towards him. Then his world seemed to go in slow motion. A beautiful blonde woman appeared in front of the bullet, catching it in her hand and throwing it back at the man who had pulled the trigger, smiling as the bullet impacted on his skull.

"He'll live. But I highly recommend you press charges." The mystery woman said, walking over to the Doctor and making sure that he was unconscious.

"Oh I will. I promise you that. Friend of yours Clark?" Alicia asked, looking up at her boyfriend with a raised eyebrow. He looked from Alicia to the mystery woman who shook her head just slightly.

"Something like that. Thank you. Looks like I owe you one." He said, and the blonde woman smiled, taking his hand. He almost stepped back, shocked that she had matched his strength.

"Then I'd like to take you up on that. Can I borrow your boyfriend Alicia? I could use his help with something." Kara said, and the other blonde nodded.

"Sure thing. I need to call the Sheriff anyway." She said, pulling out her phone to do just that.

Once Alicia was out of earshot, Clark grabbed the mystery woman by her wrist.

"Not that I don't appreciate the help, but just who the hell are you? How do you know her name?" He asked, and the blonde smiled.

"My name is Kara. It's nice to meet you Kal."

A/N: So this is a story that's been running through my head. Let me all know what you think and whether I should continue.
