The next day, Sonic the Hedgehog and Rainbow Dash stood outside of Ponyville at the starting line. Both were stretching their muscles and preparing to give it their all.
"Yo Dashie! Take a good look at my spikes cause that's all you'll be seeing!" Sonic taunted.
Rainbow grinned. "Oh yeah? Well you better be hungry because you're about to eat my rainbow trail!" she taunted.
The mayor of Ponyville, Mayor Mare, stood in the sidelines with a metal cone acting as a megaphone. "Fillies and Gentlecolts! The race of the century is about to begin! Cloudsdale's very own speedy Rainbow Dash shall be put to the test against a rather otherworldly speedy blue hero! Stomp your hooves for Sonic the Hedgehog!" she introduced.
Everyone in town now watching from the sidelines turned to the odd looking hedgehog and began whispering amongst one another.
Sonic blinked. "What's wrong? I thought this town was supposed to be welcoming! Talk about false advertising…" he said.
Rainbow Dash chuckled. "Just give them some time. They'll get used to you!" she reassured.
Sonic nodded.
Mayor Mare cleared her throat, seeing not much excitement from the crowd towards the newcomer. "Erm...With that said, let's not waste anymore time and get this race underway! Racers, get ready!" she announced.
(Race: Sonic VS Rainbow Dash)
Sonic and Rainbow Dash got into starting position.
"On your mark!"
"Get set!"
"GO!"
Sonic and Rainbow blasted forward at full speed, leaving the crowd to avoid being tipped over by the wind that followed shortly afterwards.
Within seconds of leaving the starting line, both speedsters accelerated to the speed of sound, combining the shockwaves and resulting in a Double Rainboom!
In the crowd, Twilight Sparkle used her teleportation spell to bring everyone to the park near the finish line.
Sonic began to pick up speed and pass Rainbow Dash. The blue pegasus saw this and flapped her wings as hard as she could, moving past Sonic. The blue blur forced himself to go faster. At this point, the two heroes were tied and struggling to pass one another! Sonic kicked it into overdrive, pulling off his trademark figure-8 technique. Rainbow Dash wasn't going to give up either as she threw her hooves backward and straightened her body perfectly, allowing her to slice through the air more easily and quickly. At this point, the friction from the two began to engulf the ground and clouds in a trail of flames!
Back in the park, everypony was anxiously waiting for the winner. Twilight used her magic to slow down time in her perspective. In the distance, she could see one bright blue streak and one rainbow streak approaching with the speed of a wonderbolt! "Here they come!" she yelled.
Mayor Mare grinned. "And the winner is…!"
Twilight used her magic once again to slow down time and be sure who would cross the line first. All she saw was Sonic and Rainbow Dash screech to a halt just in front of the finish line and looking up.
"Dr. Eggman?!" Sonic exclaimed.
"HOHOHOHOHO!" cackled a familiar egg-shaped mad scientist. "Why Sonic! What a pleasant surprise! Actually it isn't! I knew you'd somehow be able to follow me into this world you meddling little needlemouse!" he angrily said. Dr. Eggman sat in his egg-mobile accompanied by Orbot, Eggman's robotic servant.
The blue hedgehog grinned. "Atleast you're finally getting used to the usual schedule of things! So what's your evil plan this time? Brainwash Equestria? Take over with your robot army? C'mon Egghead, give me the details!" he jokingly demanded.
Dr. Eggman frowned. "That's none of your concern...for now atleast! You're probably thinking this plan will be another failure? You're dead wrong! This time will be different!" he declared.
Tails smiled. "Sure! Just like every other plan you said wouldn't fail! And look how that turned out!" he taunted.
Sonic chuckled. "Good one buddy!"
Eggman growled. "SHUT UP! I'm done talking! Now it's time for me to destroy! And I'll start with you, Sonic!" he stated.
"Destroy me? You and what mustache! I beat every time! I thought you would've learned that by now!" Sonic said.
Suddenly, Twilight and her friends stepped in front of Sonic, ready to fight. "If you want to destroy Sonic, you'll have to get past US first!" warned the lavender unicorn.
Sonic quickly shoved them out of the way. "Woah there! I know you're trying to stand up for me but Eggman's MY problem!" he said.
Tails nodded. "He's right. You might've fought other enemies before but Dr. Eggman is far more unpredictable! You'd better leave him to Sonic! He's got years of experience with him!" he added.
Applejack frowned with a nod. "Tails makes a good point ya'll. This is Sonic's fight so let's back off for now." she instructed.
Rainbow Dash shook her head. "No way AJ! This Eggman guy doesn't look that bad! I say we work together with Sonic! Strength in numbers after all!" she said.
Twilight used her magic to pull her back. "No Rainbow! Sonic knows this guy better than we do! I'm sure he can handle it! I know you want to work together but it's best that we let Sonic fight alone. Like Tails said; Eggman is unpredictable!" she explained.
Rainbow paused for a bit before sighing with a nod. "Fine."
Sonic smiled. "Everyone get out of here! Things are gonna get ugly!" he shouted.
Everypony did so and took cover.
Eggman chuckled before pressing a button on his control panel. The mobile began to expand in size and shape before literally upgrading itself with huge robotic arms. The top of the mobile was now a roof with sharp spikes. "Say hello to my latest weapon of destruction and your doom; Mega Arm! HOHOHOHOHO!" he cackled.
Sonic grinned as he readied himself for yet another showdown with Dr. Eggman.
