Disclaimer: I do not own Code Lyoko.

Warrior's Final Battle Part 3

Nova and Bill arrived at the factory and took the elevator down to the Computer Lab.

"So how's it going on Lyoko?" asked Nova who was helping Bill over towards Jeremy.

"They're just getting ready to enter the Replika." answered Jeremy.

"Great, now we can help them if my plan works." Bill said now standing under his own power.

"What exactly is your plan?" asked the boy genius sitting at the supercomputer.

"Send us to the Sector of whatever Replika it is and I'll go into a tower and get the information I need to get me and Nova there without crossing the Digital Sea." explained Bill.

"You can do that." Jeremy said surprised.

"Yeah, but I can only do it once." informed Bill.

"Interesting. I'll inform the others that you'll be there shortly." Jeremy said putting his headset back on his head.

"Cool, we get to help after all." Nova said excited.

--

On Lyoko the Skid was right in front of the Replika. Aelita entered the code opening the Replika so they could enter.

"Next stop, Mountain Replika." Odd said as the Skid went inside.

The new and improved Skid emerged from the Digital Sea flying towards the tower they needed.

"Jeremy, we're almost there. Get the program ready." said Aelita as she stopped at the tower that connected them to the real world.

"Ok. I'll begin to set up the process." Jeremy announced.

"Has anybody else noticed that the sky looks really weird?" asked Odd looking at the dark clouds.

"It's probably Xana trying to scare us." said Yumi.

"I don't like the feel of this, you guys." William said feeling a familiar presence.

"Don't worry about it. We can take it." Ulrich stated looking at the bizarre look of the Mountain Replika.

"Ok, so who's going?" asked Jeremy.

"Me and Ulrich will." Yumi said volunteering.

"Alright. Energize, Yumi. Energize, Ulrich." Jeremy said as they disappeared out of the Skid.

"What about the rest of us?" asked William looking towards the surface of the Mountain Replika.

"You guys are going to protect the Skid." announced Jeremy.

"From what, Einstein? The air." laughed Odd.

"No. actually I just picked up Xana's Dark Knight on the Replika." Jeremy informed.

"Time to get out of here." Aelita stated as the three teleported out of the Skid and onto the surface.

"Oh great. How are we going to beat him with only three of us?" asked Odd as they awaited the arrival of Rob.

"Well, soon there's going to be five of you." Jeremy said.

"Five. How?" asked Aelita.

"Bill has a plan to get him and Nova to the Replika." answered Jeremy.

"Well hurry it up." ordered Odd.

--

Meanwhile Yumi and Ulrich landed at the bottom of a bunch of mountains.

"Hey, Jeremy. We don't see any labs or anything." Yumi stated looking at their surroundings.

"Hold on. Let me locate you." Jeremy said bringing up a map of the world.

"Did you find anything?" asked Ulrich.

"Ah, it seems the supercomputer is located at the top of the tallest mountain." informed Jeremy.

"Well isn't that great. I don't suppose you can send the vehicles, can you?" Ulrich replied.

"Nope, sorry Ulrich." said Jeremy.

--

"Ok, Dad. We're ready to go to the Mountain Sector." Bill said reaching in his pocket pulling out a CD and handing it to Jeremy.

"What's this?" asked Jeremy confused.

"Trust me we're going to need it." Bill explained as he and Nova got on the elevator to take it down to the Scanner Room.

"Ok." Jeremy said putting the CD into the supercomputer.

--

Bill and Nova arrived down in the Scanner Room and each entered a scanner.

"Transfer, Bill. Transfer, Nova. Scanner, Bill. Scanner, Nova. Virtualization." Jeremy said sending them to the Mountain Sector.

--

On the Mountain Replika Odd, William and Aelita were waiting for Xana's Dark Knight to arrive.

"How long does it take for him to get here?" asked Odd tapping his foot on the ground.

"That's good he's taking his time." Jeremy interrupted.

"Why is that, Jeremy?" asked Aelita.

"Because if he's distracted long enough he'll be coming home with us." explained Jeremy.

"Well at least he can take my spot." William said readying his big sword for battle.

--

Deep somewhere near the supercomputer that they were to destroy Ulrich and Yumi were slowly trying to climb to the top of the mountain.

"Ulrich, remember don't look down and you'll be fine." Yumi told her boyfriend remembering that Ulrich had vertigo.

"I know. I just wish that the supercomputer wasn't on top of a mountain." stated Ulrich trying not to look down.

"Where did you expect it to be? Under water?" Yumi asked sarcastically.

"Very funny." Ulrich said not pleased.

--

On the Mountain Sector Bill and Nova landed no where near any towers.

"Dad, could you send us the vehicles?" asked Bill.

"Coming right up." Jeremy replied as the Billcycle and Overboard appeared before them.

The two jumped on the vehicles and headed off to the tower that Bill needed to get into.

--

Back on the Mountain Replika Rob had finally arrived to fight the other three Lyoko Warriors.

"Thank you for coming to entertain us, Rob." Odd joked smiling.

"I like nothing better than to entertain my guests." Rob retorted going along with Odd's joke.

"Aelita, you need to deactivate the tower before I can use the program." Jeremy explained.

"Alright, Jeremy." Aelita said as the Overwing appeared before her.

"William, we can handle this guy right." Odd said aiming his arm.

"Yeah." William smirked.

"You two are just little tiny obstacles in my way." Rob smirked.

"Laser Arrow!" Odd fired at Rob who blocked them by spinning his spear.
"I got him, Odd." William said walking towards Rob swinging his giant sword at Xana's Dark Knight who jumped out of the way.

--

At the Mountain Replika supercomputer Yumi and Ulrich were almost to the top of the Mountain. Yumi reached the top first.

"Come on, Ulrich. Almost there." Yumi said as Ulrich slowly got towards the top.

"I know." Ulrich said as he slipped on a rock. "Ah!"

"Ulrich!" Yumi screamed as she grabbed his hand and helped him up.

"Thanks, Yumi." Ulrich said as they turned around and saw the big lab.

"Hey, Jeremy. A map would be greatly appreciated." Yumi said as they walked towards the door.

"Hold on. I have bunch of other stuff going on. I'll get to it immediately." Jeremy answered.

--

On the Mountain Sector Bill and Nova ran into some Krabes.

"Isn't this lovely. Hey, Nova. Do you like Sushi?" Bill asked pulling his sword out.

"Even though I'm Japanese I find it really disgusting. I hate it." Nova replied.

Bill hit the brakes on the Billcycle and jumped off. "Sword Slice!" he called out as he destroyed one of the Krabes.

"Cat Claw!" Nova said scratching a Krabe with her claws destroying it.

"Bill!" Watch out the Scyphozoa is behind you!" Jeremy warned as Bill turned around.

"Ah, the good old jellyfish has come to play." Bill said ready to strike it.

The Scyphozoa attacked with it's tentacles. It wrapped around Bill planting something in his brain.

"Nova, save Bill before it's too late." Jeremy ordered.

"Ok." Nova replied.

She ran towards where Bill was but was shot by a Krabe from behind. She quickly got up and turned around.

"Cat Claw!" she yelled as she destroyed the Krabe.

"Nova, you lost 20 life points." Jeremy informed.

Nova turned around to attack the Scyphozoa but it already dropped Bill to the ground.

"Bill, are you ok?" she asked.

--

Back on the Replika Odd and William had their hands full with Xana's Dark Knight.

"This is getting old, Rob." Odd said as he dodged Rob's spear that was thrown at him.

"And you two are getting annoying." Rob remarked as he stopped William's giant sword with one hand.

"How can you do that?" William wondered as Rob kicked him in the gut.

"Laser Arrow!" Odd fired some more at Rob who dodged every single one of them.

"Pathetic. Both of you." Rob smirked as his spear returned to his hand.

"Well, if we are then why haven't you finished us yet?" asked William as he got back to his feet.

"Very well, then. Arise!" Rob said summoning something.

--

Aelita entered the activated tower. Inside she rose to the second platform and stuck her hand out.

Aelita…

Code… Lyoko…

"Tower deactivated." she whispered as the data files shot down around her.

--

At the Replika's supercomputer Yumi and Ulrich were wondering around the lab.

"Let's try this room." Ulrich said opening the door.

"Guys, I found it." Jeremy informed.

"So did we." replied Yumi looking around.

"Ok, don't destroy it yet. Odd and William have to devirtualize Rob first." explained Jeremy.

"Have you realized that it's been relatively easy to infultrate the lab?" asked Ulrich.

"Yeah, that's because Xana is using to much power to do anything on Earth." Jeremy announced.

--

Back on the Mountain Sector Bill was getting back to his feet.

"Bill answer me." Nova said as the boy turned around to face her.

"Xana must be rule." Bill said as the Eye of Xana appeared in his eyes.

"No! Snap out of it." Nova pleaded.

"Nova, devirtualize him right now." Jeremy ordered.

"Ok." Nova said as she jumped in the air. "Cat Claw!"

"Foolish girl." Bill said punching her in the face.

--

On the Replika the entire landscape starting shaking.

"What is that?" asked Odd as he and William looked around.

"Kolossus!" Xana's Knight call out.

Huge arms came out of the Digital Sea. The gigantic creature emerged on to the Replika.

"You know, Odd. Right now I wish I was with Xana." William said as the two stood next to each other.

"Me, too." Odd agreed.

The Kolossus quickly smashed Odd and William devitalizing them back to Earth.

"Have a nice trip." Xana's Knight laughed.

"Jeremy, I'm about to fire at Rob. Are you ready?" asked Aelita.

"Wait a few minutes. Xana's used the Scyphozoa to possess Bill." said Jeremy.

--

Odd and William fell out of the scanners weakened from the attack.

"Well that could have been better." William said getting up to his feet.

"Hopefully the rest of the gang will have better luck." Odd said sitting in the middle of the floor.

--

On the Mountain Sector Nova slowly got back to her feet.

"Hey, Bill. Is that the best you got?" Nova taunted.

"I will dispose of you and delete the Mountain Sector." replied Bill as he powered up his sword and blasted Nova.

Nova jumped over attacking Bill with her claws. Bill took his sword and sliced Nova in half devitalizing her.

Bill ran into the way tower and rose up to the second platform. He stuck his hand out.

Bill…

Code… Xana…

The Sector began disappearing deleting itself. Bill dropped to the ground back to normal.

"Materialize me, right now." Bill ordered as he ran from the disappearing ground.

"Materialization, Bill." Jeremy said as Bill disappeared off Lyoko.

--

Aelita was watching as Rob stood on top of the Kolossus.

"Aelita, shoot now. The Mountain Sector is disappearing and it might disrupt the Replika." explained Jeremy worried.

"Energy Field!" Aelita formed the orb of energy and fired it at Rob making him devirtualize.

The Kolossus turned around looking at Aelita. It smashed the poor pink haired girl devirtualizing her.

--

In the Scanner Room Odd, Nova, William and Bill watched as two scanners opened up. One Aelita walked out of and the second Rob collapsed out of but was caught by Bill.

"There you go, buddy." Bill said helping Rob over to lean against the wall.

"Thanks." Rob replied.

--

At the Replika's supercomputer Ulrich and Yumi awaited Jeremy's order to destroy it.

"Alright you can destroy it." announced Jeremy.

"OK. Impact!" Ulrich yelled as he stabbed the supercomputer with his sabers.

"Hang on. De-energize, Ulrich. De-energize, Yumi." Jeremy said as the two returned to the Skid.

The Skid started to leave the Replika as it began to disappear making the Kolossus fall into the Digital Sea.

The Replika began to shine really bright and exploded as the Skid was safe and sound.

--

Everyone gathered in the Computer Lab. Rob sat against the wall away from everyone else.

"Well we got rid of one Replika. Only twenty-six more to go." said Jeremy as the group smiled on a job well done.

"The only thing I want to know is why did Xana have me delete the Mountain Sector?" asked Bill.

Everyone turned to Rob. "I have no idea. The only thing I remember is fighting you guys all the time." Rob replied.

"What could Xana have to gain from doing this?" asked William.

"Maybe he's trying to make it to where we can only fight him on the Replikas." said Odd.

"If so then we're going to have our work cut out for us." Ulrich stated.

"AH!" Bill screamed as he collapsed to his knees in pain.

"What's wrong?" asked Aelita bending down to see if her son was ok.

"Pain. Lots of pain." Bill whined.

Nova's P.O.V.

What a monster he is. That's why he got rid of the Mountain Sector. He knew it would make Bill weaker. We'll stop you Xana and I'll save my father from your wrath.

I walked over to Bill and bent down next to Aelita.

"That's why Xana did this. He's trying to kill Bill." I said shocking everyone.

"How do you know?" Yumi asked me.

"Bill's connected to Lyoko. If a Sector is deleted then Bill gets weaker." I explained.

"How did you figure this out?" Bill asked me in a normal voice now that the pain had stopped.

"When I was captured by my father and Sam, my father told me." I replied.

End P.O.V.

"So now we have to stop Xana from destroying Lyoko again." announced Jeremy.

"How are we going to do it with only six of us?" asked Ulrich.

"Six of you. I see eight Lyoko Warriors." Rob responded as everyone turned towards him.

"William's leaving the group and we can't have you going back to Lyoko." Yumi explained.

"Sorry, buddy but I'm afraid I'm going to have to agree with them." Bill said getting back to his feet.

"So did you set up the program, Jeremy?" asked Aelita.

"Yes, I just have to scan him and use a return to the past." Jeremy informed.

"Won't that bring the Replika back?" asked Odd.

"And what about me won't I go back to being a prisoner of Xana?" asked Rob.

"No, this particular return will only affect William and any damage Xana has caused." explained Jeremy.

"We'll come meet you at the factory." Bill stated as everyone except Rob and Jeremy went to the elevator.

--

Down stairs in the Scanner Room William stepped in a scanner for the final time.

"Well it's been fun guys." William said as he awaited Jeremy to start the process.

"It's been fun having you around." Odd replied.

"And once this is all over you'll remember that you were apart of the group." Bill added.

"I will." said a confused William.

"When we return to the future you'll be apart of the gang again." Bill explained.

"Ok then. But I hope we can still be friends." William said smiling.

"I'm going to miss having you around, William." Nova said grabbing Bill's hand.

"I'm going to miss you too, Nova." William said thinking to himself.

"Are you ready, William?" asked Jeremy from the Computer Lab.

"Yes, Jeremy. Good-bye, guys." William replied.

William's final thoughts as the scanner closed were. "Nova, I love you."

"Scanner, William." Jeremy said beginning the process.

"I guess it's time." Aelita said.

"Yup." Jeremy replied. "Time for… Return to the Past, Now!"

The white bubble engulfed everything sending the world back in time but leaving Rob free from Xana and the Mountain Replika destroyed.

--

Bill was sitting in the dorm room alone because due to the return trip and erasing William's memory William was no longer roomed with him.

"Guess, I should go get Rob." Bill said getting up off his bed.

--

Out in the courtyard Jeremy, Yumi, Aelita, Ulrich, Odd and Nova were sitting around.

"Looks like the group has gotten weaker." Odd said sitting on the ground.

"We'll pull through we always do." Yumi replied.

"Should we have Rob help us?" asked Ulrich.

"No, I think it's best we keep him away from Lyoko." Jeremy stated while going through filed on his laptop.

"Yeah, he maybe me and Jeremy's nephew but we still need to keep him away from Xana." Aelita explained.

"Look there's William." Nova pointed out.

"Hey, William." Yumi waved at the boy.

"Oh hey, Yumi." the boy waved back.

"Wow, the program really worked." said Odd amazed.

"He's me and Jeremy's son. Did you think Bill's program wouldn't work?" Aelita said laughing.

"Let's go hang with William, Ulrich." Yumi said as Ulrich nodded.

"Where's Bill?" asked Nova looking around.

"I don't know. I have no idea where he was at this time to begin with." Jeremy answered.

"Oh." the blonde girl replied.

--

On the other side of the city at Nova's house in the garage Hayata Ishiyama was hard at work on his own supercomputer.

"So they got rid of one of our Replikas. I weakened their most valuable asset." the man laughed.

"You realize that you sent our weaker monster after them." a voice replied.

"I know. It'll just make our newest creation seem stronger." Hayata responded.

"How is our pet?" asked Xana.

"She's fine." Ishiyama answered.

--

At the factory down in the Computer Lab Rob sat waiting in front of the supercomputer. The elevator could be heard coming down.

As the elevator opened Bill smirked. "It's nice to have you back."

"It's great to be back, cuz." Rob smiled back.

"No more Xana inside you." Bill said waiting for a reply.

"Nope. Free as a baby." the older boy laughed.

"I didn't want to fight with the others but I trust you." stated Bill putting his hands in his pockets.

"I may not remember everything I did while I was with Xana but I do remember one thing." responded Rob.

"And what's that?" asked Bill.

"It just surprised me that you did it." Rob stated.

"I have no idea what your talking about." said a defensive Bill getting worried.

"Don't worry I won't tell the others." Rob assured.

"Thanks." Bill sighed.

"So you won't go in a relationship with Nova. Why is that?" asked the grey shirt wearing Rob.

"With all that's happened in my life I've never been able to keep a relationship healthy." explained Bill.

"You've been with like four of five girls." Rob laughed.

"I know." Bill agreed.

"I guess I should tell you that your first love is being tracked by Xana." informed Rob.

"What?" Bill asked outraged.

"Xana has been watching your ex from the United States." Rob explained.

"I have to go and help her." said a panicked Bill.

"I'll go with you but don't you think you should tell the others?" asked Rob.

"I'm going to. I just don't feel right leaving them two people down." Bill replied.

"They'll be fine. They've survived before." Rob said getting out of the chair.

"I don't think Nova's going to be happy about this." said Bill as the two cousins got on the elevator.

"She'll get over it. This is really important."

--

Yumi and Ulrich were talking with William who was now completely obliviois to knowing about Lyoko.

"Ulrich, I always thought you hated me because I tried to steal Yumi away from you." William said confused as to why Ulrich was hanging around with him.

"Let's just say that once you get to know someone you ten sometimes to like them." Ulrich replied.

"Huh, I never thought of it that way." said a still slightly confused William.

A/N: A really long chapter. And possibly the best one of the story. Will the gang be able to trust Rob? What's the pet that Xana was talking about? And where do the Lyoko Warriors go from here? Until next update.
