(Stage: Death Egg 2.0)
Sonic easily plowed his way through hoards of Badniks as he navigated the confusing twists and turns of corridors and giant machine filled rooms. After near escapes from grinding gears, pounding and thumping compactors, electrical conveyor belts, sawblades in the ceiling, and even a few flames from the main engine, he finally found himself in a huge open-spaced room.
The blue hedgehog looked around. "Eggman! I know you're around here somewhere! Just give it up now!" he yelled.
Just as he expected, Eggman descended from an opening in the ceiling. "So you managed to survive the traps I set up for you. I'm not surprised." he said.
Sonic grinned. "Well atleast you're finally catching onto how much you need to work on those machines of yours! Let's just cut to the chase. So what's it gonna be this time? Wait don't tell me! A giant robot?" he asked.
Eggman's mobile descended into a circular opening in the floor before a large lid sealed him inside. The dome rose out from the floor and revealed to be a giant robotic Eggman mech!
Sonic sighed. "Really? C'mon Eggman! You've done this like 4 times already!"
Eggman grinned. "Oh I'm not going after you Sonic!" he said before pushing a button on his control panel. Sonic was suddenly encapsulated while Twilight and the girls were shoved into the room from their hiding spot before the doors behind them sealed shut! "It's those annoying friends of yours i'm after!"
Twilight's eyes grew wide with fear. "Uh oh…" she gulped.
(Boss: Death Egg Robo)
Eggman's mech whirred to life before beginning to march forward, a loud mechanical boom with each step it took. "Hahaha! Prepare to be flattened!"
Rainbow Dash quickly zoomed up to the robot's torso before unleashing a powerful buck only to suffer from painful recoil! "YEOWCH!"
Eggman laughed. "Do you really think it's so easy? You're simple bucking is useless against this polymer alloy!"
Applejack frowned. "He does make a good point. That thing is an indestructible tank with legs! Even I can't make a simple dent in that thing!" she said.
Twilight frowned. "Let me give it a try!" she said before galloping forward.
Eggman chuckled. "That's it unicorn! Get a load of this!" he yelled.
The robot's arms began to spin like drills before coming down on Twilight.
"AUGH!" Twilight screamed as she was sent flying behind the giant robot which jumped high in the air and turned to face the dazed unicorn.
Rarity noticed an opening in the backside area as the round-shaped mech was bent over, recovering from the landing and quickly took the chance to strike with a shot of magic from her horn.
"GAH!" Eggman wailed as he stumbled along with the mech before it crashed to the ground with a loud bang.
Twilight beamed as she got back to her hooves. "There's our weak point! Now let's bring this bot down!" she proudly exclaimed.
Fluttershy flew forward and began zooming around erratically as a distraction. "Over here Eggface! No here! Missed me! Excuse me but could you try a littler harder? I'm so sorry your aiming is terrible." she taunted.
Eggman was furious. "I'll wipe that adorable smile off your face you treehugger!" Eggman barked before slamming down another button.
The robots hands detached from the arm joints and rocketed forward right at the yellow pegasus but were quickly sent right back at the mech thanks to a swift interception from Dashie. "You were saying Baldy McNosehair?" she taunted.
The mech stumbled backwards, leaving its black underside exposed.
The 6 girls quickly sprang into action and bombarded the mech with attacks before it was able to recover and get back on its feet. Only this time it began to smoke and spark.
Inside the cockpit, sparks flew everywhere and an alarm blared.
"The main engines and turbines are malfunctioning and we've lost half of our fuel thanks to the orange pony puncturing our tanks. Now would be a good time to retreat, Boss." Orbot warned.
Eggman growled. "You shut up! Those pestering ponies are NOT getting out of here alive!"
The jet exhaust burst to life as the robot propelled itself off the ground then taking careful aim at the ponies below.
Twilight noticed this and frowned. "INCOMING!" she yelled.
Everypony scattered as the robot came down with a mighty crash, bending over again.
The girls attacked once again before the robot flew back into the air one last time.
"I've had enough! Prepare to be crushed into nothing you little pests!" Eggman screamed.
Once again, the girls quickly dove out of the way before the mech came down.
Twilight and the girls were all jammed together into Pinkie's party cannon before being sent sky high to deliver the final blow; A full blown pony homing cannonball! They slammed right through the torso of the robot before scattering on the other side.
Eggman sighed. "Just my luck...my original mech, taken down by a bunch of candy colored ponies." he said right before the entire robot was engulfed in a fiery explosion.
Twilight quickly surrounded the girls and herself in a protective barrier just as the explosion reached them.
Bits of metal and robotic limbs rained everywhere. Some of it destroyed the capsule Sonic was in, granting him freedom at last.
When the smoke and dust cleared, Eggman could be seen retreating towards the next room: The core of the Death Egg.
Sonic ran over to the girls with an impressed smile on his face. "Awesome job girls! Way to take down Eggman!" he commented.
Twilight smiled. "It was nothing! Now let's go after him and settle this thing once and for all!" she exclaimed.
The group nodded before running after the mobile towards the final battle with Dr. Eggman.
