Hello again readers! I want to thank everyone who reviewed. Thanks for the info, Andrew510. I did already know that Sonic is capable of performing Chaos Control. In fact I had him use it in another story I did. Feel free to take a look if you want to.

Anyway, on to another chapter

Chapter 7

A strange alarm went off inside Eggman's main control room. Eggman frowned, "Now what? I have more important things to worry about. Like where to find..."

Just then an image appeared on the giant screen. It showed Sonic racing toward the very building Eggman was in.

Eggman howled with laughter, "This is too good to be true! Here I am about to send my newest creation out to get Sonic, and he saves me the trouble by coming to me! What a thoughtful little hedgehog. Ha ha ha ha!"

Sonic was nearing the front of the fortress. "Eggman always did enjoy penthouse views." Sonic said to himself, "I'll probably find him at the highest room in that place." As Sonic neared the front of the building he started running up the side of the giant Eggman shaped structure at hi- speed.

Eggman watched all of it on his monitors, "Although I do want him to get inside so that the fun can begin, I can't make it too easy." With that, Eggman pushed a button on his control consol, causing several doors to open up along the outer walls of the building. With the push of another button, missiles began shooting out of the holes and headed straight for Sonic.

Sonic, still running to the top of the building, noticed the missiles coming at him, and went into a super sonic spin dash. With this increase in speed, he continued to the top causing the missiles to miss him and explode as they collided with the wall.

Sonic came to a stop on the head of the Eggman building. Sonic looked around for some means of entry. Suddenly, he noticed part of the roof opening, and a large laser cannon came rising into view. It pointed at Sonic and fired, nearly missing as Sonic dove out of the way. It continued to fire rapidly as Sonic began to run in a circle around the cannon. Sonic quickly jumped into the air and performed a homing attack, blasting through the cannon.

Sonic turned and saw the giant hole in the roof where the cannon once was. Sonic smirked, "Well, that was fun! And look at the convenient door I found."

Sonic jumped into the hole and entered the base. He landed on the floor and looked around. The room was pitch black, and he couldn't see anything.

Just then, the hole Sonic came through was sealed shut by a thick metal door, plunging the entire room into darkness. Suddenly, light filled the room, and Sonic had to shield his eyes for a moment to adjust to the light. Then he looked around at his newly lite surroundings. It was a giant room with thick walls, and only one door that he could see. The other thing he saw was a flat computer screen over the small door.

The screen turned on and displayed an image of Eggman's face. Eggman chuckled, "Greetings Sonic! How was death?"

Sonic clenched his fists in anger, "Where are you, Eggman?!"

Eggman ignored his question, "Despite what you might think, I'm glad you came back. I always regretted not having the pleasure of finishing you off myself."

"Then get out here and let's get started!" Sonic shouted as he got into a fighting stance.

Eggman chuckled, "Not so fast, Sonic! How about a little warm up first?"

Suddenly, the door below the screen began to open, to reveal someone standing there. The face was covered by darkness, but Sonic recognized the creature's outline.

"SHADOW!?!" Sonic gasped.

"Ha ha ha! Not quite, Hedgehog." Eggman said. The creature stepped into the light to reveal that he was a robot. "Say hello to Robo-Shadow! Thanks to the design blueprints in my Grandfather's diary, I was able to create a robotic version of the ultimate lifeform! What do you think?"

Sonic grinned, "He does look the part. Now let's see if he can fight."

"Robo-Shadow, destroy Sonic!" Eggman shouted.

Robo-Shadow's eyes began to glow bright red, and he slowly turned his head and looked directly at Sonic. He spoke in a monotone voice, "Prepare to die, faker!"

Sonic sighed and sweatdropped, "Well, it definitely sounds like him."

Robo-Shadow jumped into the air and came down toward Sonic with a powerful right hook. Sonic quickly rolled to the side, causing Robo-Shadow to punch a hole in the floor. He then began throwing rapid punches, and Sonic began blocking at the same rapid speed.

Then Sonic went on the offensive, and quickly maneuvered behind Robo- Shadow. Robo-Shadow turned around, only to receive a powerful kick from Sonic. The force from Sonic's attack sent Robo-Shadow crashing into the wall in a cloud of dust.

Sonic dusted his gloves off and chuckled, "Well, that was easy enough."

Suddenly he heard Robo-Shadow's metallic voice, "Don't be so sure about that."

Sonic turned and saw Robo-Shadow skating toward him at full speed. Unable to react quick enough, Sonic was headbutted into a wall. Robo-Shadow then charged toward Sonic to finish him off with another powerful punch. Acting quickly, Sonic ran along the walls of the room, causing Robo-Shadow to hit nothing but the wall. Sonic continued running along the walls at top speed.

Sonic grinned, "Can't you do any better than that?"

Robo-Shadow chuckled, "I was about to ask you the same thing." Then he shouted, "Chaos Control!!" and disappeared.

Sonic was shocked, "What the...?" Before he could say anything more Robo- Shadow suddenly appeared right in Sonic's path, and performed a homing attack, sending the a very surprised blue hedgehog back down to the floor of the room.

Sonic landed on his feet and looked at Robo-Shadow land a few feet in front of him. Sonic was still surprised, "You can use Chaos Control!?!"

Eggman, who had been watching, pretended to sound innocent, "Didn't I tell you? Robo-Shadow is powered by one of the seven chaos emeralds, allowing him to tap into it's power and use Chaos Control whenever he wants!"

Sonic frowned, "Gee, I guess you forgot to mention that part."

Robo-Shadow held up the palm of his right hand, "That's not all I can do, faker!" Sparks of electricity began to come out of his hand, then he pointed his hand toward Sonic. "Chaos Spear!" Robo-Shadow shouted. Yellow thunder bolts came shooting out of Robo-Shadow's hand and hit Sonic directly, sending electricity thru his body.

Sonic was now on his hands and knees, "So you can use Chaos Spear too, huh? Well, I've got a few tricks of my own."

Robo-Shadow fired again, but missed as Sonic was now running in a wide circle around the robot. Robo-Shadow continued firing Chaos Spears at him, barely missing him each time. Sonic quickly moved in closer to Robo-Shadow and performed a Blue Tornado attack. The strong winds send the stunned robot straight up into the air.

Sonic jumped high above Robo-Shadow and dive bombed him with a homing attack. Sonic connected with the body and plowed him into the floor in a thick cloud of smoke.

Sonic leaped from the dust cloud and stood ready for Robo-Shadow to counter attack. The dust cleared to reveal Robo-Shadow with a hole in his body, but he was still functional. Robo-Shadow chuckled, "Very impressive, but did you forget who your dealing with? I am the ultimate lifeform!"

Sonic smirked, "Really? All I see is a cheap imitation with a bad case of rust!"

Robo-Shadow's eyes began to glow bright red again, "I'll show you a cheap imitation! CHAOS CONTROL!!"

Nothing happened.

Sonic pulled out a yellow emerald from behind his back, "By the way, I think you dropped this."

"That's the emerald that was inside me!" Robo-Shadow gasped.

Sonic chuckled, "That's right! I figured that the emerald that was powering you was inside your chest. So I busted a hole in it to get at the chaos emerald."

Eggman grunted, "So what? Robo-Shadow is more advanced that you realize, Sonic! He'll still be able to beat you even with that emerald!"

"Good point!" Sonic said, "Lucky for me that I brought more than one!" Sonic pulled out the red emerald that he took from Rouge.

Eggman couldn't believe it, "THE LAST CHAOS EMERALD!?!"

The two emeralds began to glow as Sonic clenched them in his hands. Robo- Shadow was paralyzed as Sonic began charging up with a super sonic spin. In a flash of light, Robo-Shadow was on the floor in pieces, and Sonic put the emeralds into his socks. He then stared up at Eggman's face on the screen, with a cocky grin.

"Well," Sonic said, "You said that was the warm up. How about we get to the main event?"

Much to Sonic's surprise, Eggman began laughing, "This is too rich! Not only did you save me the trouble of looking for you, but you also brought me the last chaos emerald! The one thing I need to give me total and absolute power!" Then the door below the screen began to open again, "I'm at the end of the hall, Sonic! Don't keep me waiting!"

Sonic didn't waist any more time. He began running down the hall to face Doctor Eggman.

A/N: Well, how's that for an exciting fight? I know it was just Sonic this time, but don't worry everyone else will be in the next chapter for sure. I'd like to thank Chosenoneknuckles for suggesting the whole Shadow robot thing. I hope you enjoyed it, dude. I'd thought about calling him Metal Shadow, but I'm sure that another fiction writer has used that by now. Anyway, please submit a review to let me know what you thought, and to motivate me to continue.

Next Time: Sonic the Hedgehog VS. Doctor Eggman!

It's gonna be good!!
