Completely ignoring the heat, both hedgehogs continued to fight as they fell towards the planet. Between the increase of gravity and heat build up, Shadow's advantage against his stronger opponent was quickly diminished. Sperk began to land powerful blows and even in super form, Shadow felt each one. Shadow hit Sperk in the face with a chaos empowered punch. As Sperk fell back from the blow, he rammed his fist into Shadow's gut. Sparks flew as Shadow's super form prevented the sharp knuckles from impaling him. The two floated apart as the friction from their reentry began to increase. A silent truce was formed and the two curled into their ball forms. They shot through the upper atmospheres and hit normal air. They uncurled and plummeted towards the ground. Sperk opened his quills and started to control his decent. Shadow tried to use his chaos power to control his fall, but with his quills, Sperk was able to gaincontrol fasterand slam into him. As they fell, Sperk hammered punches into Shadow and the two fell into a bay next to a city. The water exploded into the air as the two continued to fight. Their combine chaos auras formed a dome that held the water back as it tried to reflow into the bay. Shadow rammed his head into Sperk's and jumped back. He curled into a ball and slammed into Sperk. The force sent Sperk into the air and he landed on top of a large skyscraper near the middle of the city. As the water flowed into the bay, Shadow flew into the air and shot at the building. Sperk got to his feet and started to focus energy into his fists.

"Master Spear!" Shadow's body flashed with gold light and hundreds of energy spears shot from his body. The spears impacted the top of the building and the entire roof of it exploded. Shadow stopped and watched the pillar of smoke from a distance, "No way that finished him. Chaos Control!" He entered Chaos Time. With a loud sonic boom going off, Shadow was slammed out of Chaos Time and crashed into the damaged building. He flew through several floors before crashing out of the other side. He stopped himself by using his power.

Sperk appeared was Shadow was floating before being hit, "And he said I had no skill." He shot through the hole Shadow had made through the building.

"Not bad!" Shadow flew to meet him and the two connected with a spin attack. With a large shockwave of energy, both hedgehogs fell out of the sky. The shockwave crashed into several buildings ripping them apart. Both hedgehogs landed on the street below. The street was disserted. Luckily the citizens of the city had long been hiding in the emergency shelters. The only thing Robotnik's invasion had done right.

"I'm stronger, faster, and have more power. Why can't I beat you?"

"Power isn't everything." Shadow's super form gave out, "Granted I wish I had a little more power."

Sperk started to move towards him, but his form died off as well, "This changes nothing."

"Enough!" A small shuttle landed behind Shadow and a red echidna ran out.

"Get out of her, Leda! Even without our super forms, this place isn't safe."

"That is enough. We are free and you have proven that you are a match for Sonic and Shadow." She walked past Shadow, "Can't we just leave?"

Shadow sighed and looked around, "She is right. We have nothing left to prove to one another." Sperk grumbled, but slowly nodded his head. Shadow turned away, "You better get lost before GUN returns."

"Let's go!" Leda hugged Sperk's arm.

"This is far from over." They both disappeared in a burst of green light.

Shadow rolled his shoulders and cracked the bones in his neck, "Just like always. Fight for the better part of the day and gain nothing in the end." The sky suddenly began to grow dark, "and the fun just never seems to end."

After collecting as many rings that he could find, Sonic flew towards Earth. He stopped as he spotted a large black storm growing on part of the planet, "That has to be a major storm if I can see it from this far." Several black emeralds flew past him and into the storm. Sonic flew towards the planet. As he reached the clouds, he was blasted back by red lightning. "What is this?" He tried again, but couldn't penetrate the lightning shield. Sonic took a deep breath and closed his eyes.

The wind started to blow violently as the storm clouds darkened the sky. Shadow ran on top of a small warehouse to get a better view. The water in the bay swelled up and formed a large creature made of red water. It had large arms and its lower torso was just a pillar of water. Dozens of black emeralds floated with in the creature. It had a single glowing red eye. "Black Doom!"

"Not quite Shadow." Its voice was a combination of Black Doom and Robotnik. "Apart we have failed to take over this miserable planet. But with the Chaos we created and the power of the black emeralds, we have more than enough power to destroy you and all that stand against us." A large fanged mouth formed on the shark like head. It spat out black energy that shot around the city. Red crystals appeared on the streets. "Black Arms, awaken from your slumber." Large black creatures exploded out of the crystals and began attacking the city.

"Hey Shadow!"

Shadow looked around, "Sonic?"

"The emerald has linked our minds. Cool huh?"

"Sure! I hope you have a plan."

"I do! Just keep him from moving."

"Moving? Sonic?" The voice was gone. Shadow looked out towards the towering creature, "Keep a two hundred-story monster made of water and chaos energy from moving. Sounds simple enough."

Sonic shot past Venus and Mercury. The golden hedgehog neared the sun and started to fly around it. He turned into pure light and shot around the sun at high speeds. The sun started to flash and flares from it erupted into Sonic's path. His ring of light turned into a ring of golden fire.

Shadow slammed into several Black Arms troops as he made his way towards the red chaos. There seemed to be hundreds of them and he was running into more and more as he went. Three dropped in front of his path. Each was eight feet tall with large red talons. They attacked him, but he managed to jump back. He warped into Chaos Time and quickly took the three down before they could react. He returned to normal time. Several more troops were running at him. "This is getting old." A large black metal case was dropped next to him. He turned to see Sperk standing with another case in his hand. "I'm not really in the mood for another round."

"Take those." He pointed to the case he had dropped.

Shadow cracked the case open and pulled out a gold ring. The case was full of them, "And the reason for you being so helpful."

"My girlfriend has a soft spot for other people." He had an annoyed look on his face. He rolled his shoulders, "and I can't stand it when she is sad."

"So you here to help or just drop off these?"

Sperk eyed the approaching Black Arms, "I do enjoy a good fight."

"There is plenty to go around. You keep the troops out of my quills. I'll handle the creature."

"You're welcome to it."

"Then lets go!" Both hedgehogs absorbed their rings and transformed into their super forms. Sperk charged the Black Arms troops as Shadow teleported to the chaos.

"Ah Shadow!" The chaos turned towards the floating hedgehog.

"This ends now Black Doom or whatever you call yourself."

"Just call us Demise." He opened his mouth and a large black beam shot from it. Shadow dropped down to avoid it. He curled into a ball and flew away. He turned and shot at Demise. The chaos spat out more energy beams. Shadow picked up speed and blasted through the chaos. He roared in pain as Shadow shot through his water body.

Shadow uncurled and flew above the creature, "Chaos Spear!" Energy spears shot from his hand and exploded on impact with Demise.

"Insolent rodent." One of the large arms flew out and slapped Shadow into the water.

Shadow flew out of the water and dodged several attacks from the chaos, "Hurry up Sonic!"
