The Adventure of Two Dimensions

Prologue: The Gateway Opens

It was a peaceful day in Station Square. Dr Eggman hadn't attacked in months now, and Sonic and his friends were beginning to believe he'd given up. However, little did they know, Eggman was conducting his newest plan underneath the heroes' noses. "Faster, you idiot robots! Faster!" yelled a very excited Eggman. "I need this to be perfect! It will not work otherwise!" Eggman yelled to his Egg Pawns, slaving away on his newest machine. "Doctor! The machine is nearly complete. We only need to obtain the 7 Chaos Emeralds from Sonic for this to be a success." One of the Shadow Androids yelled up to his maniacal master. "Excellent, Shadow Android number 254. Send out Metal Sonic to retrieve the Emeralds from Sonic. His new upgrades should get the job done." Eggman commanded. The android immediately complied. "Soon, I will be able to go to a new dimension. I will be able to take it over and build Eggmanland again! And the best part is that accursed hedgehog will not stop me! Nyah-ha-ha-ha-(cough cough). Wow, being an evil scientist sure takes a lot out of you."

Sonic, Tails, Knuckles, Shadow and Amy were all on the beach, having fun, except for Sonic, who was being chased by Amy. "Go away Amy! For the last time, I WILL NOT MARRY YOU!" Sonic shouted to his demented fangirl. "Sonikku, you will marry me before this year is out!" came a voice from a very angry Amy. "There they go again, as usual." said Tails, having seen it all before. "Yeah, you'd think that she'd stop for at least a drink, but no. She just keeps chasing him." Said Knuckles, tired of it all as well. "But hey, at least it can't get worse, right?" Tails asked. Just after he said that, Metal Sonic appeared out of nowhere. "I just had to open my big mouth, didn't I!" yelled Tails. Metal Sonic's voice rang clear throughout the 5 friends, "GIVE ME THE 7 CHAOS EMERALDS, MY BIOLOGICAL COUNTERPART, OR SUFFER EXTREME CONSEQUENCES." Sonic used this distraction to get away from Amy and confronted the mechanical imposter. "No way am I giving you the Emeralds! Go rust, tin can!" Metal Sonic was unfazed by Sonic's insult. "FINE, YOU AND YOUR FRIENDS SHALL ALL DIE!" Metal Sonic's voice chip would have given out if he had yelled any louder.

Then, a fierce duel erupted between the two, as sparks flew everywhere, Sonic looked like he was gaining the upper hand, Metal Sonic used one of his new upgrades to turn the tide quickly and throw Sonic to the sand below. "Ugh! He's gotten stronger since our last encounter!" Sonic groaned. "THAT IS CORRECT, PUNY HEDGEHOG. MASTER HAS UPGRADED ME TO COUNTER YOUR WORTHLESS ATTACKS." Metal Sonic said, in his usual monotone voice. Straight after, he dashed into Sonic, knocking the Chaos Emeralds out of his grasp. "MISSION COMPLETE. RETURNING TO BASE." The robotic imposter said as he grabbed the Emeralds and flew off using his jet booster. "Sonic, get up, he's getting away!" Knuckles shouted to his downed friend. Sonic slowly rose, smirked and said in his usual cocky tone, "He won't get very far. Let's go!" At that, he grabbed Tails and Knuckles and began to run when he considered bringing Shadow along. "Hey, Shadow, wanna come?" Sonic said to his emo friend. "Fine. But don't think I'm coming for you. I'm coming for the Chaos Emeralds." Shadow said reluctantly. "Alright then, let's go!" Sonic and Shadow sped off with Tails and Knuckles in tow. "Wait for me, Sonic!" Amy said as she tried to keep up with Sonic.

"I trust your mission was successful, Metal Sonic?" Eggman said to his second in command. "YES DOCTOR. THE EMERALDS ARE IN OUR POSSESSION. WE NOW HAVE EVERYTHING WE NEED TO ACTIVATE THE DEVICE." Metal Sonic replied with a tone of hidden joy in his voice. "Good job! Are all systems operational?" Eggman enquired. "YES DOCTOR. ALL SYSTEMS ARE GREEN. INITIATING PROJECT ZETA. REQUESTING FINAL CLEARANCE." Metal Sonic told his maniacal creator. "Granted!" came the joyful reply. Metal Sonic sped off to initiate the device known as the Egg Gateway. "Sonic and his friends can't stop me now and- WHAT!" Eggman choked on air in shock. What he saw were two streaks of light slicing through his Egg Pawns. "No! Not now! Shadow Androids, move to intercept targets! Sonic and Shadow must be stopped before they get here or it will compromise the whole plan!" Eggman barked orders to his Shadow Androids, and they all complied immediately. "Metal Sonic, hurry up! Sonic and Shadow are almost here! We need to get out of here now!" Eggman desperately barked orders to his lackey. "DOCTOR, IT WILL TAKE TWO MINUTES TO WARM UP. I WILL DISTRACT THEM WHILE YOU GET AWAY." Metal Sonic then hovered to the door and went through, ready to fight.

"Geez, Eggman never learns to upgrade these things as well when he does things like this." Sonic said as he cut through a row of Egg Pawns with his Light Speed Dash. "Hmph. I agree. How did Metal Sonic beat you anyway?" Shadow enquired to Sonic. "Egghead must have upgraded him. He knows how to win a one on one duel, but I doubt he can take the both of us!" Sonic replied. "Halt, in the name of the Doctor!" said a random metallic voice sounding vaguely like Shadow's. "Oh, no. Not these guys again! Shadow, get ready! Shadow Androids, incoming!" Sonic shouted with a state of worry in his voice. Then came the horde of Shadow Androids, streaming from the one exit. "Ha. This will be easy. CHAOS SPEAR!" Shadow then released his deadly spears of energy at the clones, destroying large clusters with every spear. The smoke cleared, leaving nothing but Sonic, Shadow, Tails and Knuckles. "Hmph. I could have done better." Knuckles groaned. "Knux, calm down! Shadow cleared the path for us anyway! Onward to Eggman!" Tails said to his partner. "NOT YET." Metal Sonic's voice came ringing throughout the room. "Metal Sonic! Show yourself, you coward!" Sonic shouted to his doppelganger. "I BELIEVE WE NEED TO FINISH WHAT WE STARTED, SONIC. BUT JUST BECAUSE I FEEL SO BAD FOR YOU, YOUR BUDDY SHADOW CAN JOIN IN OUR FIGHT IF HE WISHES." Metal Sonic's cold voice soon became louder, as he emerged from the doorway where the Shadow Androids had once stood.

"Bring it on, tin opener! You're no match for me and Shadow!" Sonic cockily stated. Metal Sonic didn't play fair this time, as while Sonic was taunting him, he boosted to him and began a flurry of punches that Sonic couldn't escape from. Shadow then kicked Metal Sonic off of Sonic and into the wall. "Sonic! Tag Light Speed Dash! Now!" Shadow yelled to his partner. "Got it!" Sonic yelled back as he began to charge up energy with Shadow. The duo then released the energy and barrelled straight into Metal Sonic, sending him through the wall into Eggman's main control room. "What the- Metal Sonic!" Eggman shouted from his Eggmobile. Metal Sonic then got up with the last of the strength he had and flew over to the Eggmobile as the Egg Gateway powered up. They both attached to their newest creation, the Egg Exterminator! "This is my other newest creation! I built it along with my new machine, the Egg Gateway! It is invincible in every way! Sonic, Shadow, Tails, Knuckles, prepare to say your final goodbyes!" Eggman then began to attack the group with the strongest attacks he had. They tried to fight back, but Eggman overpowered them easily by knocking them down with an energy wave. "Wow that was easy. Come on Metal Sonic, into the portal!" He didn't notice the four getting up and dashing for him just as he entered the portal. They all jumped into the portal. "Sonic? Where are you?" Amy said as she entered the control room and saw the Egg Gateway slowly powering down. She ran and leapt in just before it closed.

The rest of the group were blacked out from the fall and from their fight with Eggman. The last thing Sonic remembered seeing were 6 multi-coloured blobs running towards him and the rest of the group with the lavender one saying, "Girls, what the heck are these things?" Then he blacked out as well.

"Ugh, Metal Sonic, what is this dimension? It looks too girly for my taste." Eggman asked his minion. "SCANNING FOR DIMENSION NAME… ERROR. ERROR. I CANNOT FIND ITS NAME, DOCTOR." Metal Sonic replied. "Well, at least there are… whatever these things are to conquer and rule over. Let's go, Metal Sonic!" Eggman ordered. "FINE, BUT CAN YOU PLEASE CALL ME METAL FROM NOW ON, METAL SONIC IS A BIT OF A MOUTHFUL." Metal Sonic requested. "Fine, fine. Let's go, Metal So-err, Metal!" Eggman answered. So they both flew off, not knowing Sonic and co. had arrived in this dimension as well…
