Sonic meets lyoko Chapter 19: Shadow's promise, a Sonic the Hedgehog + Code Lyoko Crossover fanfic

Next chapter of sonic meets lyoko! Shadow's chapter! Enjoy it friends! :D Not much else to say XD

Shadow was laying in his bed a journal in one hand and a dark pen in the other. The black hedgehog was writing down a diary of his time spent in this new dimension. Let's see what he's saying shall we?"

"It's been three months since our unfortunate transportation here to this new dimension… The children we encountered on our first day continually to help in our quest to find our way home. Although, following recent events I doubt that our going home will do much good here in this dimension." Shadow continued to write as he put the tip of his pencil to his mouth, thinking about what else to put down. "This, XANA, is continuing its constant threat to the safety of this planet and its people… and although my promise to Maria was made on a different world, does it still apply to the humans of this dimension? Are they worth protecting?" Shadow sat up and looked out the window, watching the students currently at gym run around on the soccer field and play around. He watched as birds flew around and planes in the sky flying at top speed.

His ear perked up at a noise coming from outside his door. He watched as a girl in the all too familiar pink low cut shirt and red skirt bully one of the younger male students.

"What is this?" She held in her hand a red note. "Is this a love note?" She smirked.

"G-Give it back! Please!" The boy jumped up as high as he could, trying to reach the note, but to no avail.

Sissi chuckled, "Is this a note to me?" She looked down at him. "Well?"

"No! It's to someone else! Please give it back to me!" He reached up for it.

Sissi growled. "Sorry, but all love notes NOT addressed to me are to be shredded!" She gave an evil smile and proceeded to tear up the note, chuckling in the process."

"Nooo!" The boy watched as his note fell, torn to pieces and onto the ground. "I spent all night writing this note…" He sniffled as Sissi laughed and walked away.

Shadow's usual frown and low eyebrows went to an all-time low. He quickly pulled out his journal and quickly wrote in: "The answer to that question; is not looking good." Shadow tossed his journal over to his bed and walked out to help the young child. He stood over him as the child sadly began to pick up the small, shredded pieces of the note.

Shadow knelt down and began to pick up the pieces with the boy. "Are you alright?" Shadow said softly.

The boy sniffled as a few tears hit the floor. "Yeah…" He rubbed a few tears from his eyes and the pieces of the note in his hand. "Thanks a lot for helping me pick these up though…"

Shadow stood tall and handed the pieces of paper to the boy. "Don't worry about it." He looked over as Sissi was walking away and then back to the boy. "Was that letter addressed to a girl you like?" He asked.

The boy nodded. "Yeah… I finally worked up the courage to ask her out… doing it by a note was the only way I could do it…"

Shadow looked at the boy and had a slight, sad expression on his face. "Well. I think you're brave enough to ask her out on your own." Shadow smiled lightly and put a hand on the boys shoulder. "If you could stand up to that girl then I'm sure you've got it in you to talk to the girl you like so much." The boy listened to the small lecture and began to smile at shadow.

"Y-You really think so?" The boy smiled.

Shadow smirked and nodded. "I do." Shadow gave a slight smile and began to walk away. "I know you can do it, good luck." He gave a thumb up and continued walking way.

"Th-Thank you! Um…" He tried remembering his name.

"Terios!" Shadow shouted.

"Thank you Terios!" The boy shouted back.

Shadow smirked and put his hands in his pocket. "With a boy like that, this dimensions humans may just be worth saving… but people like that sissi girl…" He was bumped into suddenly by none other than sissi.

"Hey!" She spun around. "Watch where you're going you idiot!" She shouted.

Shadow shot her an angry look, a scary one at that.

Suddenly, the unshakeable Sissi took a step back in fear, looking shadow in the eyes. "Why don't you…?" The hedgehog growled.

"I-I…" She was speechless.

He eyed her for a moment and started walking off. "Pathetic." He said as he walked off.

Herb and Nicholas watched as their leader had been stunned by this dark person. "Are you OK Sissi?" Herb moved next to her.

"Y-Yeah… I'm fine…" She mumbled as she watched him walk away. Sissi had never been scared like that before; Terios being angry at her shook her up. "I'm gonna go lie down for a bit… you two stay away from me got it?" She pointed at them both and walked away to her dorm.

Nicholas looked at Herb and back to Sissi. "Wanna go watch some TV?" Herb groaned and nodded.

Sissi opened her door and walked inside her room. She sighed and sat down on her bed. "That stupid… Terios…" She muttered, throwing a stuffed toy across the room. "Calling ME pathetic… Who does he think he is?" She grabbed another stuffed bear and held it close to her. There was a short silence. She held the bear out in front of her. "You don't think I'm pathetic… do you teddy?" She looked down at the lifeless teddy bear as an electrical socket near her sparked. "WH-What's that?" She jumped up and tossed the bear away. "S-Somebody! Help me!" She shouted as a gray spectre pulled itself from the socket of her computer. She lunged for the door but was caught as the spectre jumped onto her. Her body began to resonate with a gray color and she soon sat still. She slowly began to sit up and her eyes glowed the X.A.N.A symbol glow. "Pathetic, huh?" She stood up and suddenly began to start growing. "I'll show you Pathetic!"

Jeremy was at the Super computer, working on a code that could send sonic and his friend's home when he was suddenly interrupted by the super scan alarm going off on his computer. "Uh oh…" He quickly grabbed his phone and quickly phoned Yumi. "Yumi, there's a tower activated! Make sure to warn every…" Jeremy was cut short as a news story came up on his screen.

Shadow turned around quickly to see the gigantic Sissi roaring in the sky. "Terios!" Her voice echoed. "Come here and let me show you who's pathetic!" Her eyes had large XANA symbols on them as she walked around, crushing the roof of the school and into some of the empty classrooms.

"Geh…" Shadow grunted and burst from the hallways. He looked up to her with a glare in his eyes. "Here I am!" He shouted.

Knuckles, Amy and Sonic ran up beside shadow to help him. "Hey shads!" Sonic scratched his nose and pointed at shadow. "Think you can handle this by yourself?" He walked beside him.

"Hmph…" Shadow smirked and threw off his clothes. "You obviously don't remember who I am…" He smirked at the three. "You three go while I hold her off."

Knuckles and Sonic both looked at each other and shrugged their shoulders. "We'll finish before you know it! Good luck!" They all began to run out of sight when Amy turned around and looked at shadow, his hand began to glow a bright yellow.

"W-Wait shadow!" Amy turned around and ran over to him. "You have to be careful, I mean, she may be taken over by that Computer thing, but it's still her! You can't hurt her TOO badly… and your chaos attacks are too powerful!"

Shadow turned to her. "What?" He saw her running away and groaned. "Then what do I do?" He looked up to see Sissi roar and began to step in the direction he was in. He grunted and jumped back, just in time as her foot crashed into the earth.

"RAAAAAHH!" She threw her fist in shadows direction, He quickly side stepped as her fist hit the ground. "Hmmp!" He jumped up onto her arm and began to run up as fast as he could. He jumped up and launched a ferocious kick to her face, causing her to step back. While shadow was still in the air she swung her hand and smacked him onto the ground. He bounced and rolled onto his side, struggling to get up. "She… packs a punch…"

The group of teens were already in the mountain sector; Odd, Yumi, Amy, Sonic and Aelita were on their way to the tower while Ulrich, Knuckles and tails stayed back to help evacuate the area.

"Alright guys, this doesn't look like a major attack, so if everything goes well we should be able to launch a return to the past soon. Jeremy smiled and typed in the code for their vehicles. Odd's overboard and Yumi and Aelita's overwing. Sonic picked Amy up and began to lead the way.

"So how far off are we from the tower Jeremy?" Odd asked, doing a few tricks on his board.

Jeremy hit a few keys on his board and zoomed in on the towers location, "not too far off Odd." Jeremy smiled and looked on the map for monsters. "It looks like you guys are clear, but keep an eye out for anything suspicious."

Sonic looked overhead and noticed the all too familiar hornets and buzz-bombers. He skidded to a stop as two Mega-tanks rolled out of nowhere in front of them and two Krabs came out from the mountains behind them. He let Amy down and smirked. "Looks like we've got our work cut out for us…" He smiled as the group huddled together.

Odd, Yumi and Aelita jumped off their vehicles and huddled together with sonic and Amy. "Let's make sure to get the job done!" Odd looked back at sonic, who looked back at Odd. Both of them smirked. "Go!" They all shouted as they charged their opponents.

"GUAAGH!" Shadow rolled back and hit a tree.

Sissi laughed and stomped over to the black hedgehog. "Who's pathetic now, huh?" She had her hands on her hips.

Shadow slid onto his knee and coughed. "S-Still you…" He managed to say.

Sissi grew angry once more. "AAAGH!" She swung her hand and swatted shadow onto the schoolyard. He rolled and couldn't stand anymore. "Darn it… if I could… just fight back…" He looked around him to see all the students hiding behind dumpsters, hiding in classrooms and behind large poles. "L-Look at them… Hiding like cowards…" Shadow watched as Sissi began to come closer. "If I could fight back… I would be able to stop her…" He struggled to lift himself from the ground. "Maybe these humans aren't worth saving… Maybe I should just end her now… Maybe Maria's promise doesn't cross-dimensions like I do…" Shadow managed to sit himself on his bottom and look up at Sissi.

But, deep in school crowd, a lone boy stood up and looked over to his fellow students. "Hey! What are we doing here?" He shouted. "While we're here, sitting here and acting like little kids; a hero is out there trying to protect us!" He pointed over to shadow, the other classmates watched as shadow looked at Sissi, and they couldn't help but feel guilty. "A great person told me that if I have the courage to stand up for myself, then I'll have the courage to stand up for anything!" The boy thrust his fist into the air. "Who's with me?" He shouted.

The classmates looked at each other and then to the boy. At first, no one spoke up. But then a girl with blonde hair stood up and walked over to the boy. He immediately blushed. She stood next to him and grabbed his hand while it was in the air. "I'm with you!" She smiled and blushed at him. She turned to her classmates with an angry expression. "Who else?" She shouted.

Slowly, one by one, the students all stood up and raised their fists in the air. They all shouted and began to charge towards Shadow and the enlarged Sissi.

Shadow watched as Sissi raised her leg and was about to crush him, he closed his eyes waiting for it to come but began to slowly open them when he heard her grunting. "W…What?" He watched as all the students began to jump onto Sissi and climb onto her.

Two feet stood in front of him and held a hand out. "Hey Terios." The boy smiled and held out his hand. "Do you need some help?"

A yellow beam hit the earth near sonic, who back flipped and landed on his feet. "Heh, is that all? Just because you have a larger selection of monsters or in this case, badniks, doesn't mean you've got any more advantage than before!" He smirked and spindashed towards one of them. "Hah!" He jumped on top of it and smashed it into the other, causing them both to explode.

"Laser Arrow!" Odd fired his arrows towards the hornets that dodged them as best as they could. Odds arrows were scrapping them though causing them minor damage. Odd smirked and had his sights locked on a hornet flying directly towards him when he suddenly hear Yumi shout.

"Hyaah!" She launched her deadly fans and cut both of the hornets in half; she grabbed them with a smirk as they returned.

"Hey Yumi! They were totally mine!" He grunted.

"Sorry odd! Should have been faster" Yumi walked over to the Krabs that had surrounded Aelita. "Why not pick on someone who can kick your butts?" She smiled and held her fans out; Yumi looked over to Aelita with a smile. "You go with Sonic; we've got this covered Aelita."

Aelita smiled and nodded to her, she ran over to sonic. "Hey! Think we can head for that tower now?" She grabbed onto his arm.

"Hmm?" He turned to see her. "Sure thing! Let's go there at sonic speed!" He grabbed her up and jumped onto a closed Mega-tank. He looked over to Amy, who was smashing her hammer into its powerful armor. "Ya know Ames, I don't think that'll wor—" Suddenly he noticed the Dents in its armor. "Well… I'll make sure never to get you angry…" He sweat dropped. "But, I'll deal with this pinball for you. Just a moment Aelita." He smiled and began to rev up his powerful legs, the closed Mega-tank began to roll as sonic ran on top of it like circus performer. "Aaannd… Off you go!" He jumped of and kicked the Mega-tank off the edge of the mountain sector earth and watched it fall. "Let's get going!" He jetted off into the direction of the tower.

Shadow watched as the boy he had saved from Sissi before came to save HIM from her now. He grabbed his hand and managed to pull himself up. "You…" Shadow began.

"I never got to tell you my name." He smiled and shook shadows hand. "I'm Mark. It's nice to meet you Terios!" He smiled.

Shadow smirked, "It's glad to finally meet you Mark… but you can call me shadow… that's my real name." He smiled and shook his hand back. He watched as a bunch of the students began to climb onto the giant Sissi. "Did you get everyone to do this?"

Mark nodded. "Yeah. It was all thanks to your advice Shadow." He smiled, "If you hadn't come to help me and give me that advice I might've run just like the rest of them…" Mark frowned and looked over to the enlarged Sissi. "Well," He turned his head back to Shadow. "I'm gonna go help the rest of them… Thanks a lot Shadow!" He ran over to Sissi and jumped onto her leg and started climbing up it.

Shadow watched as all the students jumped onto Sissi and started throwing her off balance. "It just goes to show that standing United against one Enemy is better than being separated… I underestimated these human's courage and bravery…" Shadow looked at his hand. "That's a mistake I won't make again…" He clenched his hand and looked back up to the unbalanced Sissi. "With them climbing onto her, she isn't as balanced as she was before… If I concentrate I can make a non-lethal chaos spear that SHOULD cause her to fall onto her back..." Shadow's hand began to glow yellow and shake. "C'mon…" He opened his hand as a small orb of energy floated within his hand.

"ARRAAAGGH! Get off-a me you worthless pieces of trash!" Sissi shouted trying to throw the kids off of her. "I'll show YOU who's pathetic!" She shouted.

Shadow smirked and threw his arm behind his head and threw the small orb of energy towards Sissi. "Take that!" He shouted.

"Huh?" She shouted as the beat struck her forehead. "AAAGGHH!" Sissi began to stumble and started walking backwards uncontrollably. "NNNOOOO!" She tripped and fell onto her back, crashing into the earth. The students who didn't fall off grabbed her arms and legs and began to hold her down. "L-Let go of meeee!" Sissi struggled to get up, she grunted and jerked but the students held her down tight.

Shadow smiled and walked over to Mark. "You all did great… thanks' a lot for helping me." Shadow sighed and sat down, feeling exhausted.

Sonic dashed left and right, two hornets had caught up to the two of them as they made their way to the tower. Sonic looked behind him for a moment and skidded to a stop. "You go get to the tower, I'll deal with these pests…" He smirked as he set her down.

"Will do. Good luck!" Aelita ran off in the direction of the tower, which was not far off.

"Alright you freaks, let's get this show on the road!" He jumped up and kicked one of the hornets on their XANA symbol, causing it to explode. While he was falling the other hornet shot and hit him in the arm. "Agh!" He rolled on the ground and quickly stood up. "So you want a piece to eh?" He rolled up into a spindash and charged toward sit, bursting through it. "Hah!"

Aelita ran into the tower and slowed to a walk as she stepped onto the rings. She slowly floated upwards and did her usual flips as she landed onto the upper rings. She placed her hand onto the invisible console.

Aelita.

C.O.D.E

L.Y.O.K.O.

It read. The tower shut down and all the screens of data behind her fell into the dark abyss below her. She soon walked out of the tower and met up with everyone. "Well that wasn't too bad!" She smiled and stood next to everyone.

Sissi suddenly began to shrink, she groaned as her body returned to its natural size and the students started getting off of her. "Are you alright Sissi?" Mark held out his hand to her.

"Mmm?" She murmured sitting up. "I…What happened?" She groaned.

Shadow sighed and laid back. "You were kind of possessed."

Her head poked up. "Possessed? Did… Did I do anything bad?" She looked at some fallen trees and dents made into the earth. "I guess I did huh?" She frowned and sighed.

The students all surrounded her with, "It's alright" and "it's not like you meant to". Shadow watched as the students quickly forgave her and assured her that everything was alright. He smiled warmly at them. "These humans are just like the ones from my dimension… forgiving, caring… brave and courageous…"

"Alright guys! Return to the past… NOW!" Jeremy hit the enter key and the white bubble consumed the entire area…

His ear perked up at a noise coming from outside his door. He watched as a girl in the all too familiar pink low cut shirt and red skirt bully one of the younger male students.

"What is this?" She held in her hand a red note. "Is this a love note?" She smirked.

"G-Give it back! Please!" The boy jumped up as high as he could, trying to reach the note, but to no avail.

Shadow poked his head out to see the familiar sight he had already seen before. He frowned.

Sissi chuckled, "Is this a note to me?" She looked down at him. "Well?"

"No! It's to someone else! Please give it back to me!" He reached up for it. But his eye caught shadow poking his head out the door, he had a serious expression on his face and something shook up inside of the boy. "Rrrghh… Gimmie it back!" The boy jumped up as high as he could and snatched the note from Sissi. "Leave me alone Sissi! Go away!" He turned and shouted to her as he held the note strongly in his hands.

Sissi took a step back and frowned. "Fine! I didn't want that stupid note anyway!" She flipped her hair towards him and began to walk away.

The boy panted and looked over to shadow. He ran over to him and smiled. "Hey um… thanks a lot!" He smiled.

Shadow blinked, "Thanks? For what?"

"For helping me! I don't know why, but for some reason when I saw you I got this sudden rush of energy!" The boy grabbed his hand and shook it. "So thanks again! My name's mark! What's yours?" Mark smiled innocently.

Shadow smirked. "My name's Terios. I'm glad to meet you." Shadow looked down at Mark's other hand. "Is that a love note?"

Mark quickly let go of Shadow's hand and blushed. "Y-Yeah… see, there's this girl I like and I don't I have the courage to talk to her… so I spent all night writing this note instead…" He frowned.

Shadow smiled and placed his hand onto his shoulder. "I think if you've got the courage to stand up to a bully like Sissi than you've got the courage to talk to this girl you like."

Mark looked down at his hand and then to Shadow. "Y…You think so?" Shadow nodded. There was a short silence. "Well… then can you hold onto this note for me? If I don't have the heart to talk to her myself I'd like to have a backup plan." Mark chuckled and handed shadow the note.

"I'd be happy to hold onto it for you." Shadow smiled.

"You promise you won't read it? Or tear it up or anything like that?" He was putting his trust into his new friend.

Shadow took his hand and crossed over his chest, where his heart would be. "Cross my heart."

Mark smiled happily. "R-Really? Thanks a lot! I owe you one pal! I'll talk to you later!" Mark turned around and began to run out of the building. "Thanks again!" He shouted as the double doors began to close and he ran out.

Shadow watched him run off, "You owe me one? Hmph… you've already repaid me kid." Shadow walked over to his bed, grabbed his journal and sat down. "The answer to that question is most definitely a yes. These humans are definitely worth saving. Especially Mark." Shadow looked out the window once more, seeing Mark and the girl he was going to ask. He smiled as he saw the girl hug him and him hugging back. "Definitely Mark… Good job." Even though mark couldn't see it, shadow gave him a thumb's up for a job well done.
