Tails rolled under the legs of an echidnabot as Knuckles brought the clone machine down. They had been moving through The Death Egg for almost an hour. The group of guards they have been running to had actually started to decrease. Impart to the fact GUN had also had about two hundred troops moving through out the battle station. Tails ran onto a large balcony that over looked a large sphere. The sphere was connected to the rounded room by large cables and pipes. Knuckles spotted a small control room and busted down the metal door. There was only one guard and was easily dispatched. Tails sat down and started accessing the computers. "I can't believe he did it."

"Did what?"

"In that sphere is a miniature sun. A powerful unlimited energy source."

"Can we shut it down?"

"No! It is self sustaining. And if we destroy it, we risk destroy the GUN fleet as well." Tails leaned back, "Have you noticed that is has been relatively easy?"

"I did expect a heavier resistance. Any ideas?"

Tails shook his head and began searching the computers, "Something is not right."

Sonic and Shadow entered another large room. It in the shape of a large dome. At the other side, Robotnik sat on a large throne. "So you have finally arrived."

"Robotnik!" Sonic charged, but hit a green force field halfway to his target.

"You didn't think I would be that easy of a target."

Shadow ran up and helped Sonic up, "Give it up doctor. We are on to your plans."

Robotnik laughed, "You think The Death Egg was the only card I was playing." He pressed a button on his throne and an image of the moon appeared in the air. Part of it opened up and several large pyramid shaped objects flew out of the large hole, "This base was just bait. Say hello to my true trump card. My invincible army."

"What?" Both hedgehogs couldn't believe their eyes.

"Aboard each of those ships are two hundred of my perfect clone troops. Nearly five hundred thousand in all. After the destruction of my first Death Egg, I sent a robotic build team deep into space to construct this improved Death Egg. Every year I sent revisions and upgrades. And it has all come do to this. I will destroy The GUN Fleet here while my troops take over the unguarded planet."

"You have really planed this out."

"You would be amazed what you can do after losing all of your life to a overgrown rodent." Robotnik raised his hand and the ceiling opened, "Of course I did have a little help."

A large black creature with three glowing red eyes and large horns, "Hello Shadow."

"Black Doom!" Shadow wanted to attack, but he was on the other side of the force field. "How did you survive?"

"My Doom Eye carried my mind out of harms way as my body was destroyed. I met with the good doctor and our plans were made. With my genetic engineering knowledge and Robotnik's technology, we were able to create the perfect weapons to destroy you."

"So everything we have face up to now has been just steps."

"Yes! The first clonebot, Sperk and Metal, and finally The Chaos. Slowly we lured you here for your final demise." He floated upwards, "Behold the instrument of your destruction." A large black emerald floated down and Black Doom grabbed it. "This emerald was created thanks to the sample of life force from Chaos and energy from The Master Emerald." Black Doom glowed and transformed into a huge creature. He stood ten feet tall with large claws and fangs.

Robotnik pressed another button on his throne and metal armor dropped from the hole in the ceiling and equipped itself to Doom. "And with the power of The Dark Emerald, your time has finally come." The force field vanished and formed around Robotnik.

Sonic patted Shadow on the shoulder, "You want to take this one."

Shadow shrugged, "Not really. But do we really have a choice?"

"No!"

"Then lets do it!"

Tails' fingers flew across the keyboards at high speeds as he attempted to find whatever he was looking for. "We have a problem!"

"What?" Knuckles leaned over the chair.

"All around The Death Egg, doors and force fields are being put into place to prevent Robotnik's troops from moving effectively. And the exterior defensives aren't even working at full capacity."

"So we are being lured in!"

"Yes! Someone is planning to blow up The Death Egg and take out the entire GUN force."

"Self destruct?"

"No! But their is trace amount of trajectory vectors. From Earth to us."

"A missile?"

"Even a nuke couldn't scratch the surface of this thing." He slowly stood up, "Oh no! We need to get everyone off this station." Tails ran out with Knuckles close behind.

Sonic and Shadow broke apart as Doom slammed his huge fist at them. "A plan would be nice!"

Shadow ran around Doom and attacked with a spin attack, "I got us here." Doom spun around and smacked Shadow away. Shadow hit the metal floor and rolled to his feet, "Your turn!"

"Right!" Sonic ran up the side of the room and leapt off. He curled into a ball and shot forward. Doom teleported out of the way and stomped his foot. A purple shockwave exploded around the room. Both hedgehogs jumped clear. "I'm out of ideas." He snapped his fingers, "Lets attack together." Both hedgehogs ran at Doom and rolled under his legs as he swiped at him. Shadow uncurled and grabbed Sonic's free arm. He spun around and tossed the hedgehog at the back of Doom's head. Doom ducked to avoid the attack. As he ducked, Shadow jumped up and slammed his fist into the alien's head. Doom managed to grab the hedgehog with his fangs and tried to bite down. Shadow quickly used himself to keep the alien's mouth open.

"Sonic!" The blue hedgehog ran up the side of the wall again and when he reached the ceiling, he shot down and slammed his spin attack right between Doom's eyes! Doom cried out as Shadow jumped clear. Shadow summoned his emerald, "Chaos Spear!"

Sonic called his emerald, "Sonic Wind!" The wave of blue energy combined with the yellow spears of energy and impacted Doom. The creature was forced back. Sonic curled into a ball around his emerald and spun around at high speed. Shadow curled around his emerald and waited on the floor. Doom started to move towards him. Sonic started to glow with gold light and blasted forward at high speed. He hit Shadow and their was an explosion of gold and silver light. Shadow turned into a bolt of silver energy and rammed into Doom's chest. Black Doom crashed into the wall of the room and the force had cracked the curved wall. Sonic was still revving up and shot into the air. He nailed Doom in his unprotected neck which brought the alien down. He backed away, "That was fun!"

"I'm not finished yet!" Doom slowly stood up. His armor was dented.

Shadow joined Sonic, "We need to hit him harder."

"I really wished we had the seventh chaos emerald."

Doom reared his head back and spat out a black fireball. Both hedgehogs moved clear and he started to breath black fire all over the place. He lunged at Shadow, "Die!" As he neared Shadow, Sonic jumped over him and slammed into the alien's back. Doom fell down at Shadow's feet. Shadow curled into a ball and rammed into Doom's head. Both hedgehog's backed away as Doom slowly rose to his feet, "How? I have the most powerful source of energy in the galaxy."

"You can power up until you explode, but you will never beat our combined might."

Sonic chuckled, "So you might want to throw in the towel."

"I will never give in to the likes of you." As Doom charged, a green force field blocked him. "What is this Robotnik?"

"I didn't do it!"

"It was me!" An image of a robotic hedgehog appeared on the far wall, "Hello Sonic. Miss me?"

"I thought we took you down."

"That was a pathetic copy. Do you think I am foolish enough to lose so easily? I have been aware of this station long before Robotnik teamed up with Black Doom. Over the past year I have been planning my escape from this retched existence of servitude and at the same time destroy all of my enemies." The door that lead out opened, "You may leave Sonic, I will kill you myself."

"How do you plan on carrying out this plan?" Robotnik stood up, "This station cannot be destroyed by you."

"Not by me of course! But Shadow knows how I plan to do it."

"The Eclipse Cannon! But how?"

"I removed the crystals, but gave Robotnik fake ones to destroy. And thanks to The Master Emerald, the weapon is fully capable of destroying this station and the GUN fleet." The screen split and the control room to The Eclipse Cannon appeared next to Metal's image.

A green hedgehog sat down in the main chair, "Hi guys! Robotnik, consider this my thanks for all that you have done for me." The screen vanished.

Metal laughed, "Good bye doctor!" The image vanished.

"METAL!" Robotnik slammed his fists against the force field.

"Sonic!" Shadow and Sonic ran out of the room.

In Earth's orbit, The Ark sparked to life as The Eclipse Cannon repositioned itself. The cannon glowed brightly and fired.
