This is it, the final chapter. Peach and the crew now have to stop the out-of-control Nega Dragon from destroying Smash City. Will they finally succeed? Read on to find out.

"Chaos Spear!" Shadow shouted as he fired a volley of spears at the Nega Dragon. The dragon was unfazed by the attack and attempted to backhand Shadow with its claw, but Shadow teleported away. Omega was on the rooftop and opened fire on the beast. The dragon turned and breathed a large torrent of fire on him, but he moved out of the way at the last second. Sonic tried several Homing Attacks, but none of them had an effect. Espio launched multiple explosive shuriken while Vector breathed fire on it, but to no avail. Pit, armed with the Three Sacred Treasures, used his bow's special attack and unleashed a rain of arrows, but they didn't slow it down.

Meanwhile, Peach and the others worked on evacuating the city. As the gang tried to fight the dragon, the monster created more magic circles and unleashed blue lasers in different directions. The gang scrambled out of the way. "Okay? Does anyone have an actual plan?" Pit asked.

"This thing's unstoppable!" Knuckles said.

"There's gotta be something we can do!" Vector said.

"All we can do is stall for time until Tails gets here." Sonic replied.

"How long can we do that before the dragon torches the city?" Shadow asked.

"Maybe not long. Look!" Espio pointed at the sky and everyone turned to find Tails flying towards the gang on his Extreme Gear. "Hey guys!" he shouted. "I'm here with the-AHH!" Before Tails could say anything, the Nega Dragon swatted him away with its claw. "Tails!" Sonic shouted. "I've got him!" Shadow teleported to Tails's position and caught him before he hit the ground. He then teleported back to where the gang was. "You okay, buddy?" Sonic asked. "A-Okay." Tials replied. "I've got the Chaos Emeralds with me, too." The fox kit pulled out a container with the seven Chaos Emeralds. "Alright!" Sonic exclaimed. He then turned to Shadow. "Ready for some super action?" he asked.

"Finally, some real action." Shadow replied with that trademark smirk. The two then stood next to each other as the seven emeralds encircled them. The rest of the team backed away as a golden light enveloped the two hedgehogs. Their fur had now taken on a golden coloration. Sonic's eyes were now red and his quills stood straight up. Shadow's fur was a lighter shade of gold than Sonic's. "Alright! It's dragon slaying time! Super style!" The two then flew into the air and charged into the dragon, sending it crashing through several buildings. "Yo Tall, Dark, and Scaly!" Sonic shouted. "Let's have some fun!" Sonic charged at the beast with his Super Sonic Boost while Shadow unleashed several Chaos Spears.

The dragon swatted Sonic away but was unable to dodge the Chaos Spears, forcing it to stumble backwards. Sonic then used another Super Sonic Boost, hitting the dragon square in the chin and knocking it onto its back. The dragon retalitated by breathing another torrent of flame at the two hedgehogs, but they moved out of the way with incredible speeds. The two zigzagged around the dragon as it spat fireball after fireball at the duo. Shadow began charging a ball of Chaos Energy in his hand and tossed it at the dragon. The resulting explosion disorented the beast. Sonic used the opportunity to use his Arrow of Light, absorbing all the blue light around him and charging forward to hit the dragon square in the chest, sending it flying backwards into several buildings.

The dragon got up and prepared to attack again only to clutch its head and roar in pain. The beast thrashed about in agony for a few minutes before it suddenly stopped. That's when something truly bizzare happened. The hideous visage of Nega appeared on the dragon's stomach. "Heh heh heh!" he cackled, his voice more disorted. "This feels great!"

"What the hell?!" Shadow exclaimed.

"Okay, that is just eight different shades of sick and wrong!" Sonic said.

"Maybe to you, but to me this is power!" Nega declared. "I thought it was enough to create my dragon, but now I am my dragon! With its power, this world will be mine!"

"Oh where have I heard that before?" Sonic sarcastically asked. "Oh yeah! From every nutjob and psychopath I had to deal with!"

"Well, I'll just be silent while I watch the two of you die!" Nega exclaimed as the dragon spat another fireball at the two hedgehogs. The duo moved out of the way as Shadow fired another Chaos Blastat the dragon. The dragon blocked with its hands and unleashed more blue lasers from the circles near its wings. Shadow teleported out of the way as Sonic unleashed waves of golden energy, hitting the dragon square in the chest. Nega howled in pain as the waves seared through his body. Shadow followed up with a barrage of more Chaos Spears, the combined attack causing the dragon to stumble backward.

The enraged monster the took to the air and charged at the duo. Sonic and Shadow narrowly avoided the beast. "Shadow! Let's lead it out of the city!" Sonic said. Shadow nodded and the two flew away with the dragon in hot pursuit. The rest of the gang watched as they flew away. "Quickly, everyone! They're heading to my base! I know of a way we can assist them!" Eggman said. "How?" Tails asked. "No time to explain! Just come!" And the gang quickly made their way back to Eggman's base.

Sonic and Shadow managed to get to Eggman's base first as the dragon chased them. "Stop running and just accept the inevitable!" Nega said.

"Sorry Nega!" Sonic replied. "My motto is never say die!" The dragon responded by slashing at the two with its claws. Sonic and Shadow dodged the attack and proceeded to use their Super Sonic Boost, charging into the dragon from every angle. The dragon tried its best to fight back, but Sonic and Shadow were too quick. While the fighting raged outside, Eggman and the others charged into the base. "Boss, you're back!" Orbot exclaimed. Eggman shoved Orbot out of the way and began typing on the computer. "What are you doing, Eggman?" Tails asked.

"Nega used a special antenna to absorb all the Dark Gaia energy." Eggman replied. "I plan to do the same, only this time I'll reprogram it to drain the Dark Gaia energy from that dragon. hopefully weakening it enough for Sonic and Shadow to finish it off."

"Are you sure that'll work?" Knuckles asked.

"No. But it's worth a try! Now let me work!" Eggman shouted as he continued to type. Outside, Sonic and Shadow were becoming exhausted from the prolonged battle, though it seemed the dragon was faring somewhat worse. "This guy's pretty tough!" Sonic said. "Hey Shadow! Can you still fight?"

"What kind of question is that?" Shadow asked between breaths.

"Well, you've put up a good fight." Nega said. "But now it's time to end this. So do me a favor... and DIE!" The dragon began charging a massive torrent of fire, but before anyone could move, the dragon clutched its head and roared in pain as if someone was literally pulling pieces of its body apart. Sonic and Shadow looked to see a glowing anntena on Eggman's base seemed to drain the energy from the dragon. "What's happening?!" Sonic asked. "Sonic! Shadow!" Eggman said. "I'm using my base to drain some of the Nega Dragon's energy. Now's your chance! Finish it off!"

"All right! Come on Shadow!" Sonic said.

"Let's do this!" Shadow replied. Glowing with energy, the two of them charged straight at the panicking Nega Dragon, piercing it straight through the heart. Light shone through the monster as it was on its death throes. "N-No! T-This isn't how it's supposed to end!" Nega shouted. "I am Eggman Nega I am a genius! I-I-I-AHHH!" Nega's words were cut off by a shrill scream as the dragon exploded. Dark Gaia energy dispelling in a wave. Sonic and Shadow floated to the ground and returned to normal, visibly exhausted. The rest of the gang ran out to meet them.

"You did it guys!" Tails said. "With that monster gone, all the Dark Gaia energy has been expelled. Everyone affected should be returning back to normal now."

"You guys were awesome!" Pit exclaimed.

"Not bad!" Knuckles said.

"Well, it's not every day I get to save my worst enemy." Sonic said smugly.

"Don't think that you saving me changes anything, Sonic!" Eggman replied with indignanty Now that Nega is finally gone, it's back to buisness as usual." He then turned away and remained silent for a few moments before adding. "Sonic... Shadow... thanks."

"Anytime, Eggman." Sonic replied. "Just don't go making a habit of this or people'll begin to talk." At that, everyone began to break into laughter, sans Eggman who was too embarrassed about being saved by his mortal enemy to find any humor in this.

Meanwhile, back at Smash Mansion, everyone was cleaning up the mess their fights with each other caused. Due to the extensive damage, brawls would be cancelled until further notice. Everyone was also pretty embarrased about their actions during the ordeal, so there were plenty of apologies all around. Wario was in the infirmiry, sick from the hangover he got drinking too much beer. Peach, feeling a bit responsible for the whole mess and wanting to make it up to them, decided to bake some surprise apology cupcakes. "Okay everyone! Come and get it!" Peach said.

Everyone rushed to the kitchen to see what Peach had, but when they saw it was cupcakes, everyone quickly ran out the room screaming, not wanting to repeat what happened last time. "Guys! Come on! These are cupcakes!" Peach replied. "There's nothing in them!" Peach was a bit disheartened, but wholly expecting the reaction. Now she had to deal with dozens of fresh cupcakes. "Oh, what to do?" she thought. Then she got an idea. "I'll sell my cupcakes! Maybe that'll help the renovations to the mansion!"

"You need help?" asked Pit, who was with Ness, Lucas, Toon Link, and Mega Man.

"Sure!" Peach replied. And the five of them took the cupcakes and went to Smash City, ready to sell them.

The End!'
