Chapter 9: Rivals fight again:

The next world they visited was made out of data. They were in a valley and there was a city overhead.

"Man… everything's here made out of data" said Spike.

"Let's see if we can any heroes who can help us" Pit said.

As they made their way, another ship appeared out of nowhere. The blue hedgehog, the black hedgehog and the red echidna has arrived.

"Mario is here." The black hedgehog said as he was holding a red gem "the chaos emerald said so."

"It's time to settle an old score" the red echidna said.

"They must have went to that city" the blue hedgehog said "Let's sued Chaos Control and find them quicker."

Meanwhile, the heroes are in the city. Most of the people here wear armour. They gasp in shock at the likes of them.

"What did we do?" asked Tidus.

"I think they haven't saw us before" Shuyin said.

"Excuse me" a girl in a pink armour appeared "why did you came here for?"

"We here to look for some heroes to save the universe" Pikachu said "You see… errr… we're not bad guys."

"We come from other worlds" Spyro said. "We looking for some help."

"Oh. I'm sorry, we thought you were intruders. My name is Roll" she said "and I think Mega Man and Zero would like to help."

"Mega Man and Zero?" asked Ryu.

"We were looking for them" said Aku Aku "I'll tell the whole story along the way."

"OK. I take you to the training field. Mega Man and Zero should be there" Roll said.

They took them to the training ground. They found no one there.

"They must have left early" Roll said.

Crash's eyes moved a little as though he was picking up something. Then he heard it. He turned around. "Who's there?"

Everyone turned to looked at him oddly.

"What are you talking to, Crash?" asked Fox.

"Excuse me?" came a female voice. They saw coming out of a bush, a yellow fox which was standing on her two feet. She has a white stomach which goes down to her crouch. He wore purple gloves. She also has a yellow mane on her chest covering her breasts. She has green eyes and pointy ears. She has a white fur also on the tips of her ears and tail and has white feet.

"Who are you?" asked Cloud.

"My name is Renamon, a digimon from the digital world which was now destroyed by a evil man with an evil heart who carries a sword".

"Ganondorf…" Link snarled.

"There's no telling about it" Young Link said.

"So why are you here then Renamon?" asked Chun-Li.

"I'm looking for someone very important to me" Renamon said "have anyone of you seen a red dinosaur digimon have you?"

Everyone shook their heads as a no.

Renamon sighed sadly "Oh…"

"Don't worry" Sora said "I'm sure you'll find him."

"Easy for you to say" Renamon said "I've been looking for him for my entire life. I missed him so badly" she sighed sadly "Sorry to bother you."

"No problem ma'am" Tombi said.

As Renamon turned to leave, Young Link stopped her.

"Wait! We'll find him for you" Young Link said.

"Huh?" asked Renamon.

"He's right" Falco said "if we see him, we'll tell him to come back to you. So, it's a red dinosaur huh? OK. We got it."

"You will?" Renamon asked "You'll help me find him?"

"Sure" Jin said "In the meantime, go and find Edgar and the others back at my world. They can look after you while we're away."

"Thank you. All of you" Renamon smiled "Please, find him for me. I just want to see him again."

Everyone nodded and Renamon left.

"I hope we can find her lover" said Kirby.

"What makes you think whoever she's looking for is her lover?" asked Spike.

"Isn't it obvious" Ryu said "she said she missed him and she wants to see him again."

Suddenly, Crash and Fox's ears heard something

"Wait. I hear some people coming at fast speed" Crash said as he wagged his ears a bit.

"Yeah me too" Fox said "and it felt familiar."

Then all of a sudden, the 2 hedgehogs and the echidna came out nowhere and landed in front of the heroes.

"Hello Mario" the blue hedgehog smirked "we meet again."

"SONIC!" Mario gasped.

"AND SHADOW AND KNUCKLES TOO!" Luigi gasped.

"Wait… you know these guys?" asked Sora asked.

"Yeah" Mario said "they are our rivals. We fought against them at the Olympic Games. We thrashed them."

"We will hoping to fight you for real now" Shadow said "we used the Chaos Emerald to haunt you down."

"This time we will defeat you!" Knuckles said.

Sonic turned to the rest of the heroes "and who are they? A group of losers or something?"

"LOSERS?!" everyone roared in rage.

"I hate this guy and like Goku more" Ken said.

"Sonic, don't you dare mock my friends! You got it!" Mario snarled "I'll fight you!"

"Good, good. Let's settle this. But one question: Can you can take on 3 against one?" Sonic smirked "You see Shadow and Knuckles are fighting too."

"In which case, I'll be fighting too" Link said.

"Pikachu, I'll take this round" Fox said.

"But Fox…"

"Forget it. We need your energy saved when we find our enemies. Save it when you fight Mewtwo" Fox said.

"OK" Pikachu sighed in defeat.

"We gotta go" Marth said to the others "this is their battle."

Everyone fled the training area to leave Mario, Link and Fox against their rivals.

As they kept on running, Crash and Spyro talked to Luigi.

"Luigi, can your brother and the others defeat Sonic?" asked Crash.

"Well, Sonic and Shadow are very fast and Knuckles is quite strong" Luigi said "Mario did beat Sonic's speed on time, but I know sure it will be useful when at combat."

"But can they actually win? We need them" Spyro asked.

"I just hope so" Luigi said.

"Roll!" came a voice from a garage. It was a blue armour helmet man waving to her.

"Mega Man!" Roll gasped.

"We can hide here. Your friends can tell me the whole story" Mega Man called.

Meanwhile, Shadow used his Chaos Spears and threw it towards Link. Link defended himself with his shield and then leapt after him and threw his boomerang. Shadow dodged it and threw another chaos spear but Link deflected with his Master Sword. Fox dodged Knuckles' punches and used his barrier to stop him but Knuckles flew back. Knuckles then dug underground to see him. Fox managed to avoid him as he came up from underneath. Sonic and Mario leapt up high in the air and start bursting. They stopped high in the sky and burst back down again headfirst only to leapt out of the way before they hit the ground and landed on their feet. Then Sonic rolled into a ball and charged at Mario but he leapt out of the way. Shadow also turned into the ball and Link blocked it with his shield but he slowly was dragged back as Shadow, still in a ball, pushing him towards a wall. Link put away his sword so he could take out a bomb and threw it at Shadow, blowing him off him. Link pulled out his sword again and charged. Shadow got up and dodge Link's slash. Knuckles threw some punches but Fox's speed made him dodge all of Knuckles' attacks. Fox then used Fire Fox to attack Knuckles but Knuckles moved out of the way. Mario fired some fireballs but Sonic dodged them all. Sonic attacked but Mario blocked his punch.

Meanwhile, back at the warehouse, Aku Aku told Mega Man and Zero (who happens to be with them) the story.

"So these group of villains had come to take over the universe right?" asked Zero.

"That's right" Ryu said.

"And you want us to help you on your adventure?" asked Mega Man.

"That's right" Spike said. Pikachu was seemed to be listening until he sees a flash of red flew past the door. Letting his curiosity get the better of him, Pikachu goes out of the building. Cloud and Crash were the only ones who sees him go. They gone off after him.

"OK." Zero said "I guess we can help out. Anyway, it's good to be fighting alongside Ryu, Ken and Jin again."

"All right!" Spyro said turning around to look at Crash "we got more allies now. Huh? Hey, where did Crash go?"

"Yeah and where's Pikachu?" asked Yoshi.

"Hey, does any of you know where Cloud is?" asked Ness.

They looked around for them. Then Roll gasped "Oh no! They must have gone back to the battle!"

"Those idiots!" Jin said "they know not to run off! We gotta find them!"

Pikachu seemed to be following the red blare. He saw it ran into the forest where the battle is held. Before Pikachu could enter, he hears a voice.

"Pikachu!" Pikachu turned to see Crash and Cloud catching up to him "I know you're worried about Mario and the others, but there's no need to run off" Crash said.

"I know… but I saw some red guy entering the battle" Pikachu said.

"You mean there's someone else?" asked Cloud. Pikachu nodded. "No choice then. Let's find him, Crash!"

The 3 ran back to the forest.

Back at the forest, the Sega and the Nintendo warriors stopped fighting and catch their breath.

"Heh… you're good… for a fox" Knuckles said "Now, are we're gonna finish this? Or are you gonna surrender."

"We have no time to mess with the likes of you" Fox said "we have to go soon. We can't fight forever."

"Says you!" Knuckles yelled "come on tough guy. Let's fight more!"

"Man… this is gonna take a while!" Fox said.

"Well, Link" Shadow said "I say you're much more trickery than I thought. I am enjoying this. But you won't win against me, the ultimate life form."

"I don't have time to fight you more" Link warned "Look, the universe is in danger, and we can't fight now. We fight more later. OK?"

"Huh… the universe can be destroyed for all I care" Shadow said "let's finish this now."

"Grr… guess I have no choice" Link snarled.

"I'm impressed, Mario" Sonic smirked "You're got a lot stronger than we raced last time. Come on, time to find out which one of us is the best."

"Sonic, I can't fight you now, OK?" Mario said "more innocent people are gonna get killed if we don't stop Bowser and the others now!"

"You complain too much" Sonic said "I'm gonna finish our fight now."

"Grr… we been fighting for 2 hours" Mario groaned "we need a miracle to survive this."

"PYRO SPHERE!"

A fireball came out of nowhere and hit the Sega gang who fell over but landed on their feet. Suddenly, a red dinosaur came out of nowhere and landed in front of the Nintendo heroes. He has a white stomach which has a black hazard marking. He has some black straps, white claws. His ears are like tiny bat wings. He has golden eyes and has a small marking on his forehead. He stood up and looked at Sonic and co.

"Look. They said they had no time for this. Leave now" he said.

"We don't orders from a stranger like you!" Shadow snarled.

"You're all are finished!" Knuckles called.

But before Knuckles, Sonic and Shadow could finish them off, Crash came in and knocked Knuckles out by kicking him in the… err… you know where. Then he punched Shadow so hard that knocks him out. Before Sonic could react, Crash kicked him to a highest mountain knocking him off.

"Crash?" asked Link.

Pikachu and Cloud caught up to them. In no time, the other heroes including Mega Man, Roll and Zero joined them.

"So… what happened?" asked Mega Man.

"We don't want to fight no more because they were wasting our time" Fox said "if it weren't for Crash and the red dinosaur here, we wouldn't have seen our lovers again."

"Hey…" Pikachu said as he ran up to the red dinosaur "thanks for helping us out. But who are you?"

"My name is Guilmon" said the dinosaur.

"Hold on. Red dinosaur… and… ding! We have our winner" Roy said "excuse me, Guilmon. Do you know someone named Renamon?"

"H…how did you know her?" Guilmon asked in surprise.

"We just met her" Rayman said.

"I see… where is she now?" asked Guilmon.

"Back at Jin's world with Edgar" Pit said.

"Good… I will go back to her but… right now… I am on a mission" Guilmon said.

"A mission?" asked Chun-Li.

"Yes. I helping someone find his darkness so he can defeat him" Guilmon said.

"And who's that?" asked Falco, thinking he already knows the answer.

"My dear friend, and a Saiyan named Goku" Guilmon said.

"How can you be friends with that bad guy?" Zidane asked.

"I don't think he is a bad guy" Jin said "He was working for Kazuya and was forced to kill us remember? And when Sora and Crash talked to him afterwards, he didn't attack. Rather, he just talked back."

"So Goku is a good guy" Sora smiled.

"But who is his darkness?" asked Zero.

"Well, I gotta go. If you do see someone who calls himself "The Legendary Super Saiyan", call me, and I'll will tell Goku" Guilmon said "and if you see Renamon again, tell her not to worry. I'll be fine."

"OK. See ya around, Guilmon" Ryu said.

Guilmon smiled and walks away.

"Roll, can you wait for us to return?" Mega Man said "I don't want you to be in any danger. Promise me you'll wait here and protect everyone from peril, OK?"

Roll smiled and kissed Mega Man on the cheek causing him to blush. "I will, Mega Man. Zero, take care too."

"We will" Zero said.

"Let's back to the machine and head to the next world" Samus said "we wasted a lot of time already."

As the others left, Mario and Crash had a chat.

"Thanks for saving our butts today, Crash, but… you do know Sonic will come after you now for revenge" Mario said.

"I know…" Crash said "but I gotta be ready."

Mario smiled and put his hand on his shoulder as they walked away "that's my boy."

They returned to their ship and disappeared. Sonic woke up to see the machine disappeared. He felt anger. If it weren't for Crash, he would finish off Mario. He slammed his fist to the ground and yelled "BLAST THAT KID!"

To be continued…

AN: Must read again. Uh oh. It look Sonic wants to settle the score with Mario AND get revenge on Crash for interfering. But don't worry, Lara Croft and Soild Snake will be next. Plus, I promise to add Kenshin in this story a bit later. Now, guess who's Goku's darkness is. The clue is to what Guilmon said. Anyway, see ya later.
