A/N: Missing my update time was inexcusable, to say the least, and I apologize. I have started a forum through my profile for you all to yell at me, so please do. If I can, I hope to have this story finished by the end of this weekend, or at least before Christmas. I'm planning on playing through Shadow the Hedgehog soon, as the next stories I plan to write will have Shadow in a more prominent role.

Ultra Sonic 20

Silver Sonic

It wasn't hard to figure out where to go; Sonic could sense the power of the Ultima Emerald from the moment he stepped onto the EggPort. It just would take a while to get to it, that's all. Besides, running past the security defenses and defeating all the guard robots wasn't an overly hard thing to do, and it even gave him some exercise to boot.

Now all that was left to do was take care of Eggman.

After defeating the final robot, Sonic landed softly before the final door. Eggman and the Ultima Emerald were both on the other side.

He knocked on the steel door.

After a few seconds, the door slowly started to lift, and when it finally reached the top, Sonic peered into the room only to see pitch dark. Once again, it was his turn to act.

Sonic walked right in. And once he did, the door closed behind him.

Completely pitched in darkness, Sonic waited for a minute before finally folding his arms and tapping his foot.

"I'm waiting..." He said.

The lights suddenly turned on all over, and Sonic looked around to see himself in the same room he was in when he and Knuckles had to deal with Coconuts. Looking up, he saw the Ultima Emerald in a case above him.

However, that case was attached to a giant laser beam cannon.

Looking past the emerald and the beam cannon he could see the same lookout box that Eggman was in before. And there he was again, behind a console, looking intently down at the blue hedgehog.

"So Sonic, are you ready to be my super powered servant?"

"Sorry Eggman, but the test drive I had last time left me...wanting."

"Well then, why don't I make you?"

"I dare you to try."

Eggman, whose hand was lazily hovering over a button ever since Sonic walked into the room, finally found his reason to press it. Immediately the Ultima Emerald glowed as the beam cannon powered up and a shot was fired right at Sonic. Sonic quickly reacted and moved out of the way, leaving the beam to hit the ground and leave just a singe.

"Is it just me Eggman, or are your death beams lacking a little punch?"

"It isn't designed to incinerate you Sonic, oh no. That would be such a waste of possible slave. Instead, before you leave here, I'll be sure this beam will hit you, and then once again Ultra will be released, and you'll be on my side."

"In your dreams Eggman. I already figured out that the Master and Chaos emeralds don't create the Ultima Emerald. You're only using them to power this ship."

"Oh, what a smart hedgehog. How in the world did you ever figure that out?"

"When I was turned into Ultra, that's how. I could sense it."

"Well, well, well, then tell me Sonic, why did you send your friends to the power core and engine room then?"

"To make sure your two robots don't interfere."

With that, Sonic quickly dashed to the wall and started running up vertically almost immediately. Within seconds he was past the laser cannon with the Ultima Emerald and only a couple of feet away from the observatory holding Eggman. Within range, he finally jumped off from the wall and sent himself flying with a Homing Attack, but before it could reach the observatory glass, something flew in the way and bounced him back towards the ground.

Uncurling on the fall back to the ground, Sonic looked up to see what had stopped his attack. Directly above him were the cold red eyes of Metal Sonic. And he started glowing.

But, then he sensed something coming up from behind him. He could feel the rush of wind and quickly swerved mid-air to dodge. Once out of the way, he took a glance at what had moved so fast. It was Silica. And she was also glowing.

Sonic finally landed on the ground, and looked back up in time to see the two robots meet up in the air with a flash of light. Sonic covered his eyes until the light subsided, only to find that the two had combined to form Silver Sonic.

"Well then, this has gotten interesting." Eggman said from above.

"Once I take this hunk of metal out, you're next Eggman!" Sonic yelled.

"Silver Sonic, attack!"

Silver Sonic flew down with the figure of a monster, claws extended. Sonic jumped out of the way as the ground was cracked from the robot's landing. Running over to the right, the robot suddenly looked up with one of its eyes. Targeting Sonic in that instant, it was instantly off the ground thanks to its rockets and going after Sonic once more.

Sonic quickly changed direction and started running around the circumference of the cylinder room. Silver Sonic chased after him, but Sonic seemed to be just fast enough to barely out run it. Silver Sonic soon grew bored of the chase and immediately stopped, and once Sonic realized it and had run around the other side of the room, Silver had jetted off directly across and aimed another claw at Sonic's head.

Sonic stopped so suddenly he nearly tripped over himself. He ducked down just in time as the claw impacted the wall right where his head used to be. He then quickly took a step to the right as the other claw nearly impaled his chest. Seeing his chance then, Sonic pushed against the wall and kicked back Silver Sonic as hard as he could, which sent the robot back a few feet, staggering. Before Silver could recover, Sonic then used a Homing Attack right for Silver's chest that knocked him into the opposite wall.

Silver Sonic soon pushed himself off the wall and jetted upwards as Sonic spin dashed and barely missed him. From the air, he shut off his jets and dropped like a rock from above Sonic. Sonic slid out of the way and flipped backwards onto his feet. Silver Sonic landed, immediately firing up his jets again and charging Sonic once more. Sonic charged and jumped towards the robot, sending a flying kick to its face that connected. However, Silver Sonic took the hit on purpose, and grabbed Sonic's leg before spinning and flinging the hedgehog high up into the air.

The force caused by Silver Sonic's sudden spin had Sonic flipping head over heel in the air, unable to control himself. Meanwhile, Silver Sonic watched from below as Sonic made a high arc in the air before starting to come back down. The robot then launched itself with it's right arm extended, and was able to punch Sonic right in the gut, suddenly stopping the hedgehog's uncontrollable spin, and sending him flying into the wall.

Sonic hit the wall hard, back first. Slowly, he slid down until he reached the ground. Once on the floor, he moved into a sitting position and looked up as Silver Sonic landed before him.

"So Sonic," Eggman said from above, "Tell me, before I unleash Ultra once more and you become my slave forever more, what did you hope to accomplish by sending your friends onto my ship? You've already told me that you knew that the ship was powered by the Master and Chaos Emeralds, so what was the point of attacking the engine room and power room if they were only traps?"

"Well Eggman," Sonic said, pausing from pain, "since you do have me at your mercy, I guess I'll tell you. There were two reasons. First it was so Shadow and Amy could get rid of your two robots, or at least weaken them if they still made it here and transformed."

"But, unfortunately, that plan didn't work."

"Yeah, but then there's the second reason, which should be coming into action any moment now."

As Sonic finished his sentence, the ship suddenly rocked. Eggman fell out of his seat, and Silver Sonic lost his footing and fell to the ground. Alarms immediately started flashing everywhere. A door slammed behind Eggman, but it was more than likely a product of the alarms.

Sonic shakily got to his feet and looked around the room he was in. Silver Sonic quickly got up and activated his jets to hover in the air. He watched Sonic for the moment, as it looked like the hedgehog had a plan. And the way Sonic was searching around the room, ignoring the menacing robot, worried him.

The ship rocked again, and then again, each time worse than before. Eggman quickly checked the monitors at his console only to find that the ship was suddenly losing power. No, he spoke to soon, as just then the last of the hidden main power systems had shut down, and the Egg Port was completely on auxiliary power. However, with the damage caused by Shadow and Amy, the ship wouldn't stay in the air much longer. He'd be lucky if he could land it in time.

Before Eggman could plot a course for landing, a flash of light caught his eye. Running back towards the window he looked down into the room below him to see the large light manifest itself in the middle of the room between Sonic and Silver. The light slowly faded away to reveal Shadow and Amy, both looking they had seen better days, but still standing.

"You guys sure took your time." Sonic said with a grin as he saw his two friends finished reappearing from the Chaos Control.

Amy quickly leapt into Sonic's arms and gave him a quick hug before stepping aside for Shadow, who revealed himself to have the seven Chaos Emeralds.

"Next time," Shadow started as he held out the emeralds, "Listen to me when I say the thing is too strong to take on alone."

"Sure, next time." Sonic said as he took the emeralds.

Eggman, looking from above, realized what had happened. Sonic had sensed the Chaos Emeralds in the ship, and had seen through his light show from before where he 'created' the Ultima Emerald. The emeralds were there, but the Ultima Emerald was a separate emerald, one that he had helped to reawaken using the power of the emeralds. After using them, he had placed them away to power the Egg Port, using the power and engine stations to mask their energy signatures. However, with those two areas destroyed, it wasn't hard for anyone with any affinity with the emeralds to find them, in this case being Shadow. It all became clear to Eggman how easily he had been tricked. However, he still had one bet left.

"Silver Sonic!" Eggman yelled from above. "Don't worry about him transforming into Super Sonic. I designed you to be able to fight on par with him, so all that's left is to beat him!"

"You really think it'll be that easy Eggman?" Sonic asked as the emeralds started to glow and float around him. Pretty soon all seven surrounded him, spinning in a small hoop until the light from them grew too bright for the eyes. Once the light faded, Super Sonic was revealed, saying, "Then bring it on."

Super and Silver both immediately flew up, facing off while spinning around the laser cannon holding the Ultima Emerald. The two continued to fly up, keeping the cannon in between, until Super Sonic decided to make the first move. Speeding up in the same direction he had been going, he soon reached the other side and caught right up to Silver Sonic, throwing the first punch.

Silver blocked the punch with his arm before throwing a punch with his free arm. Sonic dodged by flying back, but Silver continued the punch, flying after Sonic with his arm like a spear. Sonic back-flipped and flew under Silver and kicked upwards into the robot's underbelly, and Silver Sonic rebounded a couple feet away before blasting his jets in another direction to charge Super Sonic. This time, his attack hit in the form of a tackle, and the two Sonics hurtled down and hit the ground with a loud crash.

Silver Sonic was the first to fly up afterward, but Super Sonic was right behind him, grabbing the robot's leg as he kept on flying upward. After dragging the robot near the ceiling again, Super Sonic started to spin the robot around by the foot, gaining speed before launching the robot into a wall. Silver Sonic outstretched his claws and created the softest landing he could, his bulky arms taking most of the impact, and then used his now hooked claws to climb up about a foot, just enough for Sonic to charge headlong into the wall where the robot just was.

Silver Sonic took this opportunity and flew down, grabbing Super Sonic by the quills and whipping the golden hedgehog across the room into another part of the wall. The robot then struck Super Sonic with a clawed fist across the face, and then another to the gut, before grabbing him by the neck and flinging him again into another part of the wall.

Flying after the hedgehog, Silver Sonic was suddenly grabbed by the leg. Looking down, Super Sonic was seen whipping the robot by the leg towards the ground. Before Silver Sonic could land, Super Sonic spun himself into a ball and quickly crashed straight down with a Super Homing Attack to Silver Sonic's midsection, cracking the armor that was there. The two powerful fighters then hit the ground with a large crash and lots of smoke.

The smoke took a while but finally cleared to show Super Sonic standing over the powered down forms of Metal Sonic and Silica.

"Well, I guess they really were weakened from fighting my friends." Super Sonic quipped.
