Sirens blared in the hammersbase. Marth, Ness, Agumon, Geno and Meta-knight escaped with the chaos emerald power source and one of the three lost legendary stars. The bases commander sat in his throne and leapt up ready to stop the intruders.

"Stop, commander!" said Metal Sonic, forcefully. Metal sonic knew the truth. This commander was only given the position so he wouldn't join the heroes. "Leave them" finished Metal.

The commander sat down with a groan. He was bored and wanted action. Metal turned and left the room and the commander was pissed off that he had been kept out of every fight. His black and red spines were itching to spindash something and his chaos powers were trying to burst from his hands

"Screw this!" he shouted and blasted the door down with chaos spear. He exited the room and saw Metal Sonic looking at him, shocked. (Well… as shocked as a robot could be.)

"Commander Shadow? What are you doing?" he asked, angrily.

Shadow frowned. "I quit!" he replied and dashed towards him, blowing up the Brawnbots and Shadow Hands. Metal dodged quickly and watched as Shadow started his escape.

Metal activated his tannoy system "All troops! Commander Shadow has betrayed us, stop him at all cost. Repeat. Stop him at ALL COST!"

Shadow jetted through the base, destroying any robots in his way, and then obliterated a wall to get out. The robots and hands continued to follow and Shadow did his best to destroy them, and soon came across a way to lose them. He had found a field of overgrown plants. He blasted inside hoping to lose them.

Matt continued to desperately search the overgrowth to find Sonic, but with no luck at all. Suddenly, he heard something coming. Out of nowhere, Shadow smacked right into Matt, knocking them both down.

"Ow! Watch where you're going!" said Matt rubbing his head.

Shadow hopped up. "Tch... whatever kid..." he replied before dashing off.

"Hey! What's the hurry?" Matt shouted after Shadow. He turned to where Shadow came from to see a whole battalion of Shadow Hands coming his way. "Aww shit!" he exclaimed and sprinted after Shadow.

Shadow hadn't realized that by using his jet boots he was clearing a path that both Matt and the hands could follow. He continued going until he eventually left the overgrowth to a clearing, but the clearing was nothing but overgrowth on one side and a cliff on the other.

"Damn!" said Shadow

Finally, Matt caught up to Shadow... but so had Metal Sonic and the Shadow Hands.

"Forget it Shadow! You've lost!" said Metal. He clicked his fingers and all the Shadow Hand merged together, creating two, full size, Master Hand and Crazy Hand replicas.

"ATTACK!" commanded Metal Sonic, and two hands began.

Matt dodged to the left and began to fight with the "Shadow Master" while Shadow took on the "Shadow Crazy". They had mostly the same moves as the real hands but they also could spawn smaller hands and shoot temporary clones as projectiles. Matt eventually took down the "Shadow Master" with an axe kick and joined Shadow in fighting the Crazy clone. But bad guys play dirty and the "Shadow Crazy" smashed the ground hard, causing both Matt and Shadow to fall from the cliff... to their doom?

…One week earlier, in another dimension.

Tails, Knuckles, Amy, Cream and Cheese were in Tails' workshop, gathered around the dimensional portal that Tails created.

"Shouldn't sonic be back by now? What's taking him so long?" Asked Knuckles, clearly annoyed. "I need to get back to Angel Island already!"

"Please calm down, mister Knuckles. I'm sure he'll be back soon" Replied Cream. Suddenly, the door opened and shadow entered calmly.

"Is Omega here? He and I have some business" He asked. Shadow then noticed the large machine in the centre of the room. "…What is that?"

"This is a dimensional portal. Sonic used it to go help save a world that is under siege. And no, I haven't seen Omega" Tails said. "He should be back by now though"

"Hmph…" was the only reply Shadow gave, and he then simply left the building. The group sat in silence for a few seconds when suddenly, there came a loud slashing noise and Shadow blasted through the door in pain before tumbling into the portal. The group look through the door and saw Dr Eggman inside of his Egg Emperor mech. Alongside Metal Sonic.

"OOOH HOHOHOHOHO! A little birdy tells me you're hiding something from me, Foxboy!" The Doctor announced. They looked up and saw the Egg Carrier floating above the building too. Tails looked at knuckles and nodded.

"Amy! Get cream out of here. Me and tails will take care of Egghead" Knuckles shouted. Amy nodded and took Cream's hand then led her and Cheese out the back way. Tails curled into the spindash position and Knuckles lifted him up and then launched him at the Egg Emperor. The mech raised its shield and smashed Tails backwards with great force. Tails crashed with a loud clatter right through his tool bench. Knuckles let out a growl and charged at Eggman with a fist prepared to punch. Eggman knocked him backwards too, though and tried to impale him. Knuckles dodged the lance and tried to counter but just threw the lance of course. It smashed into the portal and it began to spark. The machine let out a loud groan and suddenly exploded with light. Everything around it began to get sucked in. Knuckles, The Egg Emperor, Tails, Metal Sonic and, somehow, even the Egg Carrier! Before the workshop had a chance to implode on itself, the machine stuttered and cut out. The light disappeared and the portal turned off completely… the workshop was totally empty. From a little while away, Cream and Amy watched what had happened, and had no idea what to do…
