This fanfic starts right before the last episode of Code Lyoko, ep. 95, Echoes. Xana has been destroyed, and the gang is on it's way to destroy the supercomputer. However, as they are getting ready to do so, a surprising change of situation forces the team to make a rough decision: should the materialize the new life form they have found, (OC) or should they assume it's another XANA trick, and destroy her as well?

This OC's name is Clarity, and you will get to know about her as the story progresses! All you need to know, prior to the story, is that this story's cover image is what she looks like on Lyoko.

Jeremy Belpois slid down the roped gingerly, his hands shaky with excitement. Today would be the end of it all; the skipping class, the late nights, the mortal danger, the abnormality in his life. Today, he and the other's were finally going to shut down the supercomputer that he had discovered when he was only eleven. Now, two years later, he had successfully extracted Aelita, and now, with X.A.N.A gone ,there was nothing stopping them from finally leading regular, teenager lives.

"Come on, Einstein, we haven't got all day, hurry up! Rosa told me she made spaghetti today, and I want an extra helping of meatballs," Odd called from the elevator.

"Relax Odd, I'm coming," Jeremy responded, walking into the elevator and punching in the code to shut the metal door. Quickly, he keyed in the code for the programming room, one that he had typed in so many countless times before. Aelita gently held his hand, and smiled at him reassuringly as the elevator began to descend into the factory.

After some groaning and protesting, the elevator doors opened, revealing the blue lit room; the control center, where all their Lyoko missions had been coordinated and directed from. Jeremy sighed, looking about the room one final time, and walked slowly over to the chair and keyboard he had sat at hundreds of times.

"Jeremy, I thought we were headed to the supercomputer room," Ulrich groaned, leaning against the elevator's wall and shaking his head.

"That's just like Einstein, can't stop programming for a moment," Odd said. "It's a shame, really."

"Believe me, Odd," Jeremy called over his shoulder, "I won't be doing any programming for the next few days after this. I could use a break! I just wanted to stop here real quick and grab my headset. It didn't come with the supercomputer, you know." He snatched his personal headset off of the keyboard, and began turning around and heading back to the others. He glanced at the several screens nostalgically, and his eyes found something strange. "Well, that's peculiar," Jeremy muttered, turning back to face the screens.

"Come on, Jeremy, if we don't hurry, not only will we miss all of lunch, but I will be late for my math class," Yumi sighed, crossing her arms impatiently. Jeremy looked at the elevator, then back at the screen, then back to the elevator filled with his friends again, counting in his head.

"Jeremy? What's wrong?" Aelita called, tilting her pink head in worry. She walked over to Jeremy, and looked at the screens as well. After a moment, her eyes widened in surprise. "Oh my goodness!"

"What? What's going on?" Odd asked, running over to the computer screens as well, slowly followed by Ulrich and Yumi.

"There's a genetic sequence reading being picked up from the forest sector by the supercomputer's most recent downloaded content that I programmed. According to the readings, there is… someone on Lyoko." On the screen, a green arrow was moving around the screen meanderingly and slowly, as if it didn't have a destination in mind.

"Maybe it's William," Ulrich growled, his voice thick with suspicion. "It wouldn't be the first time he went around behind our backs."

"No, I saw William going into the principal's office before lunch started. He got caught defacing some walls in the boys lavatory," Aelita said, shaking her head.

"Well, who is it then?" Ulrich questioned, itching the back of his head.

"I'm not sure, but… their signature arrow? The one that tells me your location on Lyoko? This one is green… just like Aelita's." There was a moment of silence.

"And… that's significant?" Odd asked, raising an eyebrow.

"Well… yes. All of yours are yellow, same as William's. Aelita's been the only one to ever having a green marker." Jeremy put his earpiece in, and turned it on quickly. "Hello? Hello? Unknown life form, can you hear me?" At his voice, the green arrow froze on screen. Then, suddenly, it shot across the screen quickly, before disappearing into a white circle. "Whoever they are, they aren't responding, and they just went into a unactive tower." There was a moment of silence, as the group pondered the meaning.

"Come on, Jeremy. Let's go shut it down already. For all we know, it's one of X.A.N.A's leftover traps, and we are walking right into it! I say, we just shut it down now, before we sign up for another three years of a virtual war that none of us want to fight."

"No, don't," Aelita whimpered, shaking her head. "If that is, in fact, a person on Lyoko, than we can't just shut down the computer! We would be condemning someone to a endless cyber sleep, and they would be stuck there until someone else turned the computer back on! And that's if someone can even find it, and compute it, and understand all the coding involved."After a moment of silence, she looked at her toes. "I know what it's like to be stuck for years, giving up most of your life…" After some thought, Jeremy sighed.

"Alright, fine. You guys will go on one, final mission to Lyoko. Let's find out who this mysterious being is," Jeremy nodded, turning back to the computer.

"Alright, one final mission for the Lyoko Warriors!" Odd cheered, running back to the elevator first. The elevator whizzed down to the scanner room below, and Odd and Ulrich stepped into the scanner's first.

"Transfer Odd, transfer Ulrich. Scanner Odd, Scanner Ulrich. Virtualization!" Jeremy punched the enter key on his key board, and the two boys landed squarely in front of a tower, the forest sector soaring above them. "Alright, guys," Jeremy's voice said, from above. "The person is inside the tower. Enter with caution. Yumi and Aelita are on their way."

"On the case, Einstein," Odd said, sashaying over to the tower. "I've got this," he called over his shoulder, waving off Ulrich's advance. Odd gently placed his hand on the tower's black base, and with a quiet whirring sound, was absorbed inside. Odd opened his eyes, and instantly felt self conscious of his ridiculous, purple cat suit.

Sitting in the center of the platform, her eyes wide with fright, sat a girl. Her eyes took in his form, and she tugged on her long, green locks nervously as her other hand slowly slipped behind her back, where Odd couldn't see.

"Wow! Cool hair! You look like one of the fighters from my Street Fighter games! Hi, I'm Odd, and it's a plea- -" From around her back, the damsel yanked a long, black, two pronged whip that glowed a bright pink. In the blink of an eye, the twin tails lashed across Odd's chest, and sent him hurling out of the tower. As he scuttled across the ground, and stopped next to Ulrich's feet, Aelita and Yumi dropped down from above.

"Odd! Watch it!" Jeremy cried from above, his voice scratchy from the virtual feedback. "You just lost seventy life points!"

"With one hit?" Odd gasped, standing up slowly.

"What happened!" Aelita asked, helping him up. Just then, the unknown girl dashed out of the tower, and zipped by the group of four.

"After her!" Yumi said. As the chase began, with Ulrich leading the way, Aelita ran behind the others, shielding herself from damage. "Jeremy, you can send our vehicles now," Yumi called, huffing as she sprinted after the disappearing green hair. Whoa, she was fast!

"On their way," Jeremy apologized; the Overbike virtualized directly in front of Ulrich, who flipped onto it effortlessly. "Care to hop on, princess?" Ulrich called back. Aelita climbed on, slightly more cautious, with a smile; Yumi and Odd, each on their own respective vehicles, whizzed by. "Let's go," Ulrich said, revving the throttle and following the others.

They quickly gained ground on the mysterious female, her orange skirt flapping behind her. "She looks like a fairy," Yumi called behind her.

"Hey! Pixie! Hold up, we just wanna' talk!" Ulrich shouted. "Surround her! We've got to get her to stop and talk to us," Ulrich ordered. The other's sped up and encircled her. Odd whipped around, hovering in front of her, holding his hands up calmingly.

"Hold on, we just want to talk," Odd said, trying to smile charmingly. With a grunt and a smirk, she pulled out her first whip, and, hidden behind curtain of green hair, pulled out a second one. She began to shift her weight rhythmically, her twin whips snaking across the ground.

"I'm not one for conversation," she said. Odd blinked; her voice was so…familiar! Where had he heard it before? With a high pitched grunt, one of her whips lashed quickly forward, snapping at the Overboard beneath him. It flickered out of existence, and Odd fell clumsily on his back. Turning around, as if moving in a sacred dance, she spun and lashed one of her whips at Yumi, hitting her squarely on the face. She cried as she fell back.

As Jeremy shouted that Yumi had lost sixty five life points, Ulrich helped Aelita off of the Overbike. "Go, hide behind those rocks over there," her whispered. As Aelita dove for cover, Ulrich yanked out his twin katanas. "You're not the only one with two weapons," Ulrich shouted, calling the aggressive strangers protection. "Super Sprint!" Ulrich dashed forward, his blades ready. The girl's eyes narrowed, and just as Ulrich was getting close enough for impact, she smiled.

"Safeguard!" she cried. Her long, slithering whips retracting back to her; in a nano second, the whips were surrounding her in a large, seething black orb. Ulrich slashed at it quickly, only to have his blades deflect away uselessly. As he took a breath, the four, knobbed ends of the bull whips flicked out viciously, slashing Ulrich on the chest, and sending him flying backwards.

"Ulrich!" Yumi cried, running to his side. The black shield around the stranger untangled, and she smiled innocently as the coils rested motionless on the ground around her.

"You're going to have to do much better than that, X.A.N.A, if you want to beat me," she smirked, shaking her head.

"Laser Arrow!" Two of Odd's arrows dug into her shoulder blade painfully from behind, and she screamed in surprise. She whipped around angrily. She sent one of her whips out with a flick, and Odd braced for the pain, squeezing his eyes shut with anxiety. Her whip wrapped around Odd's body, pinning his arms and tail to his body as he was cocooned with the black leather. With a yelp of surprise, he was yanked across the forest floor, face to face with the aggressor. She twirled him around, and buried her fist into his blonde hair, yanking his head back to a extreme angle.

"Uh, guys!" Odd whimpered. Yumi, who was helping Ulrich to his feet, gasped at seeing him captive. Her other whip slithered around menacingly, a wordless warning.

"Drop your weapons," she hissed. With a grumble, Ulrich and Yumi threw down their swords and fans. There was a moment of absolute stillness, then with a twitch of her hand, her second whip shot out. The two twin heads wrapped around their ankles, one around Ulrich, one around Yumi. With a tug, both crashed onto their backs.

"Aelita, now!" Ulrich shouted. Aelita jumped out from her cover, and the stranger tilted her head to the side, a confused furrow in her brow.

"Aelita?" she questioned.

"Energy Field!" Aelita shouted, sending a pink orb at the fighter. Releasing Odd from her web, she dodged out of the way, rolling out of harm's way.

"Thanks," Yumi nodded, grabbing her fans off of the ground. "Hiyah!" she screamed, throwing her right fan at the fairy girl. With an easy twitch of her wrist, one of her whips rose into the air, and the fan was knocked to the ground.

The four advanced on the girl slowly, creating a wall of weapons she didn't dare cross. She glared at each of them in turn, but her gaze settled uneasily on Aelita.

"Let's finish this," Yumi said, raising her other fan.

"I couldn't agree more," Odd sneered, locking the stranger in his sights, raising his paws.

"Stop!" Jeremy's voice screeched from above. The girl physically flinched at his voice, and then set her blazing glare on the Lyoko sky above. "Stop! Don't hurt her! She's Aelita's sister!"
