So no one said anything about combining the chapters, so I'm posting them as they are.
By the way, Samuel does something stupid, and no one thinks to say anything, because, as the title of this chapter hints at, the Final Boss appears!
The town known as Station Square was having a relatively peaceful day. The flickys were singing, people were walking through the streets, each with their own destinations in mind. The wind was blowing, the temperature was cool. Many of Station Square's citizens thought that today would be a perfect day.
They were wrong.
Song: Ganondorf's theme - Ocarina of Time
Eggman Nega was returning to Station Square, where he was looking over Ivo Robotnik's plans. "He had four Chaos Emeralds in his possession. He knows that his beast isn't ready yet, but I suppose this is a necessary risk. We need all the pieces, so why not bring them to us?" He turned his face towards a massive ship heading his way, with a smaller blue plane flying behind it. "I did my part. Now you do yours, then I'll take all the glory!"
Samuel sat down a short distance from the edge of town. He and Lucy sat in wait. Jasmine and Jennifer watched from afar.
"This is stupid!" Jennifer said. "Why are we waiting!?"
Samuel didn't bother turning his head. "Something's not right. Ivo and Nega attacked at almost the same time, and now they're both returning to Station Square. This doesn't add up. I thought Eggman was after something in Mazuri! His research notes didn't disagree with me either, so why's he coming back?"
"Research notes?" Jasmine asked.
"Sometimes I'd pass the time by breaking into Ivo's base and look over his plans. This plan was something interesting. It had to do with a Boteracean legend. The Sky God's Temple."
Lucy scoffed. "What does that scientist hope to accomplish by intruding on Boteracean holy ground?"
Samuel shook his head. "Doesn't matter now. He's heading back, and you smell that too. Something smells off underground."
Jasmine and Jennifer noticed the clouds blocking the sun, and took off their hoods. "I can hear something as well." Jasmine said.
Samuel looked up. "A clear sky was also predicted, and I wasn't sensing much moisture in the sky earlier. So those clouds shouldn't be there." He thought a bit. "The only other plans that he hasn't used yet has to do with mind control, but it's still in development. He can't be that smart as to finish something like that in a week, right?"
Jennifer spoke up. "What about that ring?"
"My grandfather took 20 years to develop these rings, and the purple one isn't as strong as he would've liked it to be. I don't think anyone could develop technology more powerful than this in less than 15 years at the very least, and Ivo hasn't started developing his mind control device until 5 days ago."
Jasmine shook nervously. "If he were finished with it, what could he be using it on?"
Samuel put his ear to the ground. "I can't tell. Could you try listening?"
Jasmine bent down, before Jennifer picked her back up. "You don't have to listen to the mutt. Let me do it." She put her own ear on the dirt, and concentrated. "There's something down there." She stood up, her eyes widened, and her legs shaking. "Something big."
Song: Morpheel second half
Samuel watched as water from a bunch of sewer drains came rushing up. "Eggman's gonna flood the city!?"
Jasmine gasped. "We have to stop him!"
Samuel looked down. "Oh…" He was shot far up into the air when the drain he was standing on erupted. When he landed he was face to face with a sort of water person. He jumped up and stood in a fighting stance, then he looked at it's head. "What are you? Some sort of mutant chao?"
He was given no response. Only an extendo arm to the face.
Samuel reached for his staff and rushed at the creature. He had no way of blocking the strikes being launched at him, so he dodged most of them. He managed to hit the beast in it's head a few times, at which point it screamed. "What? Got a headache?"
Song: Encounter - Kingdom Hearts
The being grew two metallic bone structures leading to glowing lights of Cyan and Yellow in it's hands.
"Fancy." Samuel said. "But you don't look too tough." He ran at the monster ready for an attack. He was surprised when it turned into a bubble. One that hurts.
Samuel went flying backwards. Lucy helped him up. "Let me handle this one."
She ran towards the ascended beast with claw extended. She tore through the bubble and slammed the beast on the ground.
It pushed her off and slammed her into the roof. Samuel ran forward and swiped at it with his own claws. The beast was knocked off balance, but managed to push Samuel into a wall.
"Alright. THUNDER FLARE!" The beast of water was shocked was paralysed by the power Samuel possessed. But it wasn't enough.
The beast changed shape again. He appeared to be a whale with arms.
Song: Chaos's Theme
Eggman appeared in his flying chair thing. "You fools! Chaos hasn't even shown you his FINAL form!"
Samuel and Lucy looked up at him. "He can still transform!?"
"Ho ho ho! You won't last to see his final form! Even Sonic wouldn't be able to beat this guy alone!"
"That's what you think!" A blue trail appeared, and crashed into Chaos. It landed next to Samuel, and Sonic himself appeared. "Hey there, doc!"
"What! Metal Sonic and Gamma should've beaten you!"
"We're here, aren't we?"
The rest of Sonic and Shadow's group converged on this point, and Eggman Nega appeared next to Eggman.
"Omega should've been here with the last Emerald by now." Nega stated.
"That thing couldn't handle us!" Silver yelled.
"Doesn't matter! 6 should be plenty! Chaos! Reveal your penultimate form!" Eggman screamed.
Chaos stood still.
Samuel laughed. "I get it. Those lights must be Chaos Emeralds. As long as we have three of them, Chaos won't be transforming any longer!"
"You still have them!?"
Samuel started juggling them. "See for yourself." Just then, a blast of water hit the entire group from behind. "What!?"
They all looked up to see Chaos transforming yet again. He became a frog like creature with a tipped tail.
Song: Menace - Dragon Ball Z Budokai Tenkaichi 3
Shadow ran forward and kicked Chaos in the head, but only succeeded in getting his foot stuck.
Knuckles tried to punch Chaos in it's gut, but got similar results.
Sonic tried his tried and true spin dash, but disappointed himself. He ended up stick to Chaos by his quills. "Hey! Get me out of here!"
"You think you've got it bad? He's still trying to attack me while I'm stuck!" Shadow said while swatting the tentacles away.
Samuel watched the curb stomp battle, as more of his friends tried to get the advantage. "I think I have an idea." He said. Tails walked up to him.
"You thinking what I'm thinking?"
"First things first. I'll go rescue Shadow."
Tails stared at him. "Why Shadow?"
Samuel returned the look. "Shadow has a Chaos Emerald. If Chaos get's his hands on that, he may very well be invincible." He jumped forwards, and grabbed Shadow when he past him, and brought him back to Tails.
"Thanks." Shadow said.
Samuel nodded, then turned to Chaos. He lobbed a ball at the beasts head. It absorbed it and the ball settled itself right in there, and when it exploded, Chaos froze.
"No way! I can't believe this!"
"Now, Shadow!"
Shadow ran forward. "I'll finish this in one attack!" He grabbed on to his wrists and took off his rings. "I won't allow you to get any more powerful!" He burst into a yellow ball of light.
"Whoa!" Samuel said as Shadow crashed into Chaos.
When the smoke cleared, Shadow was on the ground with everyone else, and Chaos no where to be seen. Shadow put his rings back on, and reached for his quills. He found nothing there. "What the hell!?"
"What?" Sonic asked.
"The Emerald! It's gone!"
Everyone got up and looked towards Station Square. It was flooded in water. Sonic could see people in boats and on the rooftops, but it didn't look like everyone made it.
The group, as well as the Eggmen, were heading upwards to avoid drowning. Sonic's group found themselves on a roof that happened to have Chris and his cousins on top of it.
Maria ran up to Shadow, sobbing. "I can't find Grampa or Abe!"
Shadow shook his head. "There's nothing I can do."
Chris walked up to Sonic, who he noticed was shaking. "Are you ok?"
Sonic shook his head. "There's… so much water…"
"Oh. You can't swim." Sonic nodded.
The group watched as Chaos began tearing buildings apart. The Eggmen were laughing a little ways away.
"Now, Chaos! Level the city, so that I may build my empire, Robotropolis!"
Chaos looked at Eggman, and swatted him away.
"You… How DARE you! Stupid beast!"
Nega laughed. "You lack vision, alternate me. I figured you would be unable to see the things you could accomplish, so I took the liberty of taking full control of the monster."
Eggman stared at Nega. "You traitor! We were going to rule together! Two heads are better than one!"
"Not with your head. Now Chaos! Find the Sol Emeralds, and take them for yourself!" Nega commanded. Chaos began moving towards Sonic's group.
"What!? He's already powerful enough as is! Any more powerful and he may break free of the mind control!"
"Yours, maybe." Eggman Nega said. "But I have equipped Chaos with an even more powerful device. I've been developing it for decades."
"Grr! You won't get away with this!" Eggman threatened.
"Hit me with your best shot!" Nega retorted.
Sonic's grouped looked on as certain death came towards them. "Now what?" Knuckles asked.
Song: Tikal's theme
It was then that they saw a pink orb flying towards them. The orb dispersed when it reached them, and from it appeared a pink echidna. "I hope I'm not too late."
"Who are you?" Knuckles asked.
"I'm Tikal. I was tasked with protecting a piece of the Master Emerald for when the world would need it's power."
"You have part of the Master Emerald?" Sonic asked.
Tikal nodded. "As long as Chaos has the Chaos Emeralds, he'll be invincible, but if we use the Master Emerald's power to neutralize the Emeralds, then he should revert to his normal form."
Knuckles took out his section of the Emerald, and Tikal joined it with hers. The Emerald glowed with immense power. "We have to do this fast, before Chaos reaches us!" Amy yelled.
Tikal put her hand on the Emerald. "The servers are the seven Chaos."
Knuckles joined her in chant. "Chaos is power, enriched by the heart."
"The controller is the one that unifies the Chaos. Only you can do this. Stop the Chaos Emeralds!"
Sonic, Shadow, and Samuel looked towards Chaos to see the seven lights fly from his body and land by them as grey Emeralds.
Tikal picked up one of the Emeralds. "Chaos absorbed the energy of the Chaos Emeralds. He won't revert, but he is weakened."
"But how will we use the Emeralds? We can't beat him as we are." Samuel stated.
Sonic smirked. "Maybe we won't need the Emeralds." And he jumped onto the Master Emerald. "Let me show you the power of Super Sonic!"
