Ok. Now this is my first ever fanfic that I have done so I'm still advancing. First of all, there are a few mistakes in the story. This is mainly due to the fact that I created it at the end of season one but Aelita is on Earth with the others, but then it seems to skip a few episodes. Plus I know some of the details are wrong but hey, its my story so this is how I wanted them.

Code Lyoko characters, locations and objects all copyrighted to Moonscoop. The polt and my original character is mine.

So please review! And enjoy!

"Happy Birthday Aelita!"

Aelita walked into Jeremy's room and saw that it had been decorated with balloons and banners and on the desk next to Jeremy's computer was a medium sized cake covered in pink icing and had the words "Happy Birthday Aelita" in purple icing. You could tell it was home made by the way the words were all wobbly.

"Oh wow! Has it been another year already?" asked a slightly confused yet happy Aelita.

"Afraid so Aelita. And we still haven't found out how to destroy Xana without hurting you." replied Jeremy with a slight frown upon his face.

"Can we just eat, PLEASE! I'm starving!" Odd asked desperately looking at the pink cake that was on the table next to him. "Please?"

The gang just burst out laughing whilst Odd stood rooted to the spot with a confused daze upon his face. "What? What did I say? Quit laughing at me!"

With that Ulrich served out the pieces of cake. He gave a piece to Aelita, one to Jeremy, one to Yumi, and handed his piece to Yumi, who understood why. This meant that the rest of it was for Odd.

"Ok Odd. The rest is yours, like usual."

Odd's eyes lit up when he saw how much was left and started shoving the cake into his mouth stopping every now and again for air.

Aelita Hopper (also known as Stones whilst at Kadic), Jeremy Belpois, Odd Della-Robbia, Ulrich Stern and Yumi Ishiyama were the closest group of friends at Kadic Academy, even though they did have their amount of arguments over nothing. But this group was also the most secretive of the school, because they had a secret that no one else was allowed to know about.

This was that Aelita was an A.I that lived inside a supercomputer in a world named Lyoko. Aelita was the only inhabitant of Lyoko, unless you count the dangerous virus, Xana, that was after her memories. It had been only 3 months ago that Jeremy had finally been able to materialise Aelita so she could live with them in the real world, but it had been two years since they had first met Aelita so they called that day Aelita's birthday.

Aelita had bright pink hair that came to her ears and deep pink eyes, similar to magenta. She wore a yellow t-shirt underneath a dark pink jacket and a black knee length skirt and black shoes. She was fourteen.

Yumi had black shoulder length hair that suited perfectly with her deep brown eyes, almost black even, and was in her normal black polo neck jumper, her black pants and black boots. She was sixteen.

Jeremy had blonde hair and wore black glasses around his bright blue eyes. He wore a light blue jumper with his light beige pants and blue shoes. He was fourteen.

Ulrich had glowing emerald green eyes which was sometimes covered by his brown hair, he was wearing his khaki pants, his light green t-shirt and an over coat that was slightly darker than his t-shirt. He was fifteen.

Odd had to be different and have bright luminous purple eyes, his hair was blonde and was spiked up with a purple patch situated in the centre. He was wearing a purple top with long sleeves, purple pants and yellow shoes. He was fifteen, just like Ulrich. Yumi was in the year above, but the others were in the same year.

Aelita was sat on the bed next to Yumi and she was next to Ulrich as well. Jeremy was sat on his computer chair and Odd was sat on the floor still shoving his cake into his mouth as if he hadn't eaten for days, when actually they had only just had lunch, and Odd had his normal five portions of mains and five desserts.

"Odd slow down will you, you're gonna have a stomach ache!" Ulrich told

"I… can't… hel…help it." Odd replied in between chewing. He swallowed his food and continued. "It ain't my fault I'm hungry!"

"Odd, you're always hungry!" replied Yumi which caused the group to giggle, even Odd.

Just then a shrill whistle came from Jeremy's computer, and a large red exclamation mark came up on screen. The gang watched Jeremy dash to his computer and type in large amounts of code.

"Xana's launched an attack! We need to get to the factory, quickly." Jeremy replied as the group were already dashing out of the room. "Hey, wait for me!" as he himself ran after his friends.

Jeremy had almost caught up to his friends as he was running across the football field when he saw Aelita turn around to search for him and saw her face drop in shock.

"Jeremy watch out!" Aelita yelled as a green hornet came into view behind Jeremy. Jeremy, still running, turned his head and saw the monster close behind him, charging up to fire it's laser. He ducked as the laser went extremely close to him and began to run faster.

When he reached the sewer opening he quickly got in and closed the cover to stop the hornet following him. He jumped down and grabbed his scooter noticing that the three skateboards and the other scooter had already disappeared from their normal places. He raced down the sewer and reached the ladders going up near the factory in record time. He climbed out of the sewer and ran towards the factory and jumped for the rope that the group used to get to the elevator. Jeremy hated sliding down the ropes but he knew that it was the quickest way down. When he was quite close to the bottom he felt the rope break at the top and saw that the hornet had indeed followed him and shot its laser at the rope. This made Jeremy fall but he quickly recovered and ran into the elevator, punched in the code and watched the hornet try to reach him as the doors shut.

Jeremy got off at the first stop and ran over to the Supercomputer. He noticed that Aelita, Ulrich and Odd were already in Lyoko but was looking for Yumi. Surely she hadn't been devirtualised already!

"Finally! What took you so long to get here Jeremy?" Jeremy jumped as Yumi came out from behind the supercomputer and asked her question with her eyes narrowed.

"I had a hornet following me. I managed to get rid of it before I entered the elevator" replied Jeremy calming slightly. "It looks like Aelita and Ulrich needs your help, Odd has just been devirtualised. Hurry up and get down to the scanners now!"

"I'm going! Let the others know you're here and that I'm on my way." Yumi answered as she dashed into the elevator and closed the doors.

"Aelita, Ulrich do you hear me? Yumi is on her way now. Just try and hang on for a couple more seconds!" Jeremy started talking into the ear piece he had slipped on.

"We're trying Jeremy, Xana must be really annoyed at something cos these things are coming at us from no-where!" Ulrich's voice replied.

"Yumi, your off to the desert region. Apparently the others were sent to the wrong co-ordinates. The others will meet you there soon." Jeremy's voice spoke over the intercom. Yumi got into one of the large circular holders. But not before she helped Odd into the elevator. Jeremy's voice came back. "Transfer Yumi. Scanner Yumi. Virtualisation!"

Yumi landed in a desert with only a few things in sight. She looked down and noticed she had her usual Lyoko outfit on and smiled. She was dressed in a short red and black kimono with white flowers on, a yellow belt which tied around her waist and had a yellow bow at the back. Her pants were black with white and black shoes.

"There you are Yumi!" Yumi turned round and saw Aelita waving at her whilst running towards her. Ulrich was still nowhere to be seen.

"Where's Ulrich? I thought he was with you and had some life points left!" Yumi asked Aelita. Yumi was still getting used to Aelita's appearance in Lyoko even though they have been fighting in it for two years.

Aelita had her normal short pink hair, but was wearing what looked like a yellow tracksuit underneath a dark pink cropped top with light pink detail around the edge, a dark pink skirt, dark pink pumps with straps going up her legs, and on her left elfish like ear hung a single earring.

"He was right behind me!" Aelita said slightly shocked that Ulrich was indeed, nowhere to be seen. "Jeremy, is Ulrich with you? Has he been devirtualised or is he still on Lyoko?" Aelita asked to the sky.

Jeremy's voice answered her question "No he isn't here on Earth. I'll run a scan to see if he's on Lyoko now"

Everything went quiet as Jeremy started typing codes into the supercomputer trying to find Ulrich. After a few seconds Jeremy leant back in the chair and had a face of confusion and worry. He couldn't find Ulrich on Lyoko, and there was no records saying he had returned to earth. Where was he?

"Erm… Aelita. Yumi. I can't find Ulrich. I've searched all of Lyoko and he hasn't come back to earth." Jeremy told Aelita and Yumi sadly. Both girls looked at each other with the same face as Jeremy. Odd crawled out of the elevator and looked at Jeremy's face. "Hey! What's up?". His reply was simple. "Ulrich's missing".
