Sonic woke from his slumber at the sound of of his home phone ringing. He opened one eye without rising, considered getting up to answer, then decided against it. The phone continued to ring, much to Sonic's annoyance. He disregarded it a second time and closed his eyes again. Still, it rung. Thoroughly sick of the disruptive ringing, Sonic got up with a groan and answered. "Whaaaat?" he asked petulantly.
"Sonic," Tails' worried voice responded, "Mobius is under attack!" Now Sonic was listening.
"By who?" he asked.
"Metal." Sonic assured Tails that he would be over in a second. This was bad. Metal Sonic had been one of the biggest threats Sonic and his friends had fought before. Quickly, Sonic put on his shoes and ran to Tails' house as quick as he could. Startled, Tails gasped as Sonic instantly appeared before him. "Woah," Tails said in awe at Sonic's speed, "you weren't kidding when you said 'a second.' "
"So are we doing this alone?" Sonic asked his furry friend.
"Of course not," replied Knuckles's voice as he approached from Tails' house with Amy and Cream close behind, "Do you really think I'd let you hog the fun all for yourself?" Amy ran to Sonic.
"And," Amy added, "do you really think I'd let you risk yourself against that rust-bucket? Besides, I have a score to settle with him!" She was now worked up and began to stomp her feet rapidly. Cream quickly ran to calm Amy down.
"Amy" she whined, "save your rage for the battle field." Amy sighed.
"You're right, Cream," she said, soothed at her friends' words.
"We should really get going now guys," Tails reminded them. With a nod, they all sprinted full speed to Mobius.
Sonic and his allies found Metal Sonic trapping a group of flickies in a blue, glowing net. "Why does Doctor Eggman always have to incarcerate the innocent animals?" Cream asked from behind Metal Sonic. The blue machine turned around to see Sonic, Tails, Knuckles, Amy, and Cream before him.
"Hostile subject detected," Metal Sonic boomed.
"Yeah," Knuckles replied, "nobody gives a-"
"Initiating elimination protocol. Terminating." The hole on Metal Sonic's torso began glowing inside. Suddenly, a laser shot out of it. Sonic and Tails jumped to the right while Knuckles, Amy, and Cream dodged to the left. The 5 charged at Metal Sonic simultaneously. Knuckles and Amy ran at him while Cream, Sonic, and Tails flipped over him and landed behind. Knuckles attempted a punch at Metal Sonic's face, only to be avoided by Metal Sonic merely tilting his torso to the left. Immediately after that, Metal Sonic (and Knuckles) ducked under Amy's mallet swing. Then, Metal sidestepped to avoid Cream's flying kick with Cheese at the center of her feet, which was followed by a kick from Sonic that Metal swayed away with his arm. Tails ran at Metal and attempted a tail-swipe. Metal backflipped over it, but Sonic, Knuckles, Amy, Cream, and Cheese were all hit. "Hey!" Knuckles complained, "watch who you're hitting.
"Sorry!" Tails squawked. Coated in a yellow aura, Metal rammed into Tails from behind. Tails crashed into the corner with all of his injured friends. "This is inevitable," Tails grunted as he rubbed is aching head, " We are going to end up striking one another if we all take him on at the same time."
"So I guess we each take him on one on one until he falls," Amy said.
"To end this as soon as possible, " Knuckles said, "I'll go first." Sonic rolled his eyes.
"Cocky as ever, aren't you?" Sonic chuckled. "Well, go for it, knucklehead."
"You've got this Knuckles!" Tails cheered.
"Kick his butt!" Amy added.
"Please be careful," Cream pleaded. Knuckles popped his neck and fists as he approached his opponent.
"You ready, tin can?" Knuckles cockily asked Metal Sonic.
"Low-intelligence organism identified as 'Knuckles', " Metal Sonic responded.
"Hey!" Knuckles complained, "who you callin' low-intelligence?!"
"What does it look like, knucklehead?" Sonic mocked from behind. Knuckles literally growled. Feeling there was no more need for words, Knuckles began the battle. He lifted an enormous chunk of earth from the ground at threw it at Metal Sonic. Metal Sonic merely shot the boulder with a laser from his chest, destroying it instantly. Knuckles smiled. That was just what he was counting on. Using the gargantuan dust cloud from the destroyed earth chunk as a smoke screen, Knuckles jumped forward and halted his momentum when he was directly above his opponent. In the air, Knuckles positioned his entire body downwards, pointed a fist to the ground, and spun rapidly as he fell to the floor with spiraling flames circling his body. Instead of impaling Metal Sonic with his flaming fist, Knuckles was knocked away as soon as he made contact. Bewildered, Knuckles stared at the dust cloud where Metal Sonic stood. As the dust cleared, Knuckles could see that Metal had activated a black, rhombus-shaped shield around his body. That was what had knocked Knuckles away. Instantly, Metal Sonic appeared in front of Knuckles and swung his palm into a swift chop. Knuckles barely reacted in time to duck under it and retaliated with a punch. Metal Sonic tilted his head to dodge it, and he followed with a hook-punch. Knuckles caught it, however, and flipped him over. Knuckles raised both fists over head and attempted to swing them down on his fallen opponent, but Metal kicked his legs up to counter Knuckles' attack. Knuckles soared through the air and at last landed hard on the floor. He barely had time to roll to the side as Metal Sonic fired a laser at the spot Knuckles was just in. Knuckles ran to Metal and delivered a punch to the gut that sent the robot crashing through a tree. Suddenly, a portal opened beneath Knuckles' feet, and Knuckles fell to his knees. The portal was a gravity field that was making Knuckles feel like he was shackled to the floor. Metal shot him with a laser from a distance before he could get up. "Mr. Knuckles!" Cream cried out in concern. "Let's go Cheese!" she called to her partner. Cheese jumped into Cream's hand, and she chucked him with amazing force at Metal Sonic. Metal Sonic turned around and punched the ground. A wave from the force of the impact rose from the ground and threw Cheese higher into the air. Cream flew at Metal Sonic with her feet pointed at him. Metal Sonic immediately jumped to dodge Cream's flying kick. He coated himself in a yellow aura once again and charged down at Cream, who did a jumping cartwheel kick to parry it. Now she was in the air and Metal Sonic was grounded. The robot uppercutted at his aerial opponent. Cream parried it with an axe-kick with Cheese following the trail of her foot to magnify the strength. Then she dove down with a kick as Metal ascended with a rising uppercut. Once again in the air, Metal swung his fist down, but it clashed with Cheese, who was amplifying the strength of Cream's upward chop. The impact launched Metal higher into the air, so he let himself land, ducked under Cream's kick, and punched her in the stomach. The blow sent Cream crashing into Knuckles' unconscious body. Just as Amy was about to step in, Metal received an order from Eggman. He had been ordered to retreat. "Understood," Metal Sonic said, "returning to HQ."
"That's good," Sonic told Tails and Amy, "I don't think we would have won this."
"Agreed," Tails responded, "we should take Knuckles and Cream to their respective houses to rest." Sonic slumped Knuckles onto his back, and Tails carried Cream in his arms. "Look," Amy pointed out, "he left the flickies in the net." Amy freed the flickies, and they ran and flew away. Following their lead, Sonic, Tails and Amy headed back as well.
When they returned home, Sonic, Tails and Amy placed their injured friends on beds to rest and recover. Cheese was losing it, however. She was going nuts. Tails assumed she was worried about Cream. However, Cream then woke up. "Cheese," Cream groaned, "what's wrong?"
"Chao, chao!" she responded. Cream's eyes widened as she let out a loud gasp.
"Woah," Amy interjected, "what did she say?" Cream shook her head and began to cry.
"All of the Chao in Mobius are gone," she weeped.
