"Alright, here's the plan!" said The Doctor. "Fluttershy will carry Sonic to the base and find a way in! Once inside--"
"Wait, wait!" interrupted Elusive. "Why don't you just take us all in with your TARDIS?"
"We can't!" said The Doctress. "Both TARDIS are processing some information about dimension travel, so we can make a safe travel back home!"
"If we interrupt and restart later, all the data will be lost and we may never go back to our home universes again!"
"Not in one piece, at least!"
"Ok, back to the plan!" said Elusive.
"Right!" continued The Doctor. "Once inside, Sonic will look for a way to save Cream, Butterscotch and Dr. Eggman!"
"What about us?" asked Twilight.
The Doctress grabbed her Sonic Screwdriver, and so did The Doctor.
"We keep the army occupied!"
"Sounds good to me!" said Knuckles.
"Ah reckon this might be dangerous!" said Apple Jack, digging the ground wth one of his hind legs. "But Ah've been wantin' for some action to start since Ah landed here!"
"Ah know how ya feel, partner!" said Applejack, nudging him.
"I'm getting a little rusty!" said Shade, snapping her fingers. "It will be good to keep me in shape!"
"I'm ready!" said Sonic.
"Me too!" said Dash, putting a foreleg around Sonic's neck.
"So am I" said Blitz, putting a foreleg around Dash's waist.
"Let's finish this!" said Blaze.
"If Sonic is ready, I'm ready!" Amy said, hugging Sonic's waist. Rainbow Dash glared at her and she glared back.
"I'm ready too!" Silver said, floating a few inches above the ground.
"M-Me too!" said Fluttershy, flapping her wings, flying a few inches above the ground as well. Silver put an arm around her, making her blush.
"Ready, Butch?" asked Rarity.
"Ready, Sundance!" answered Elusive. Both giggled.
"I'll help save Cream, no matter what!" said Tails, spinning his tails and flying a few inches above the ground.
"Time to rock and roll!" said Charmy.
"Yeah!!" cheered Vector.
"We'll stop them at any cost!" said Espio, assuming his ninja position.
"Since I'm already this deep, why retreat now?" shrugged Rouge. "I'm in!"
Twilight and Dusk hoofbumped.
"Let's do our best!" she said.
"You bet!" he said.
Shadow grabbed his pistols and Pinkie jumped on his head.
"Let's get this party started!!" she shouted.
"My party cannon is ready!" said Berry, pulling a cannon out of nowhere.
"It's settled, then!" said The Doctor.
"Raus, raus!!" shouted The Doctress, pointing a hoof toward the gate and galloping, leading the way.
Fluttershy put the key around both her neck and Sonic's, put her hooves around his torso and took off, carrying him.

"It's all that winged horse's fault!" Eggman said angrily. "I bet those blueprints he gave me included a bretayal programation!"
"Yes, Dr. Eggman, you already said it five times!" Cream sighed. "By the way, what are you a doctor of anyway?"
"I'm a podiatrist!"
"Okay, then..."
"Anyway, who that 'Cyber Prince' thinks he is?"
"The Prince of the Cybermen?"
"That was a rhetorical question!"
"Grumpy as always, eh, doc?" a voice said from the other side of the door. When it was opened, it revealed the one and only Sonic The Hedgehog.
"Sonic?! How did you passed the--"
"I had some help!" he said, spinning the necklace in his hand, then Fluttershy came into view.
"Go-Good morning!" she said shyly.
"I-Is that...?" Butterscotch finally said.
"Yep! Fluttershy, Butterscotch, meet yourselves!"
Both gasped, then the colt looked at Cream and the mare looked at Sonic, both saying at the same time:
"He/She doesn't look like me that much..."
Cream giggled and Sonic approached the prisoners, untying them.
"Thank you, Mr. Sonic!"
"Yes... Thanks..."
"Why did you took so long, Sonic?"
"Mr. Sonic just saved you and that's all you have to say?"
"What? You wanted me to kiss his feet?"
"It's cool, Cream!" said Sonic. "He's Eggman, after all!"
"Where are the others?" asked Butterscotch.
Fluttershy pointed her hoof at the window. The pegasi, the rabbit and the scientist went to look through it.
"They need my help down there! Gotta dash! Heheh! Now i'm starting to talk like her! Anyway..." he left the room before finishing the sentence, leaving them looking through the window.

Applejack and Jack bucked away all the robots they could.
Knuckles and Vector destroyed them with punches.
Shade and Espio used their martial abilities to smash them.
Pinkie Pie and Bubble Berry shot them with their party cannons.
Shadow shot all of them in the head (or eye in the case of the Daleks).
Amy Rose smashed them with her Piko Piko Hammer.
Twilight, Elusive, Rarity and Dusk shot them with magic beams.
Tails, Rouge and Charmy used diving moves to attack them.
Silver and Blaze teamed up, using their powers against the machines and cover each other.
Sonic joined the group, spindashing the robots.
The robots tried attacking with their death beams, but they couldn't hit a single one. And when they were about to, Dusk or Twilight was there to cast a force field spell.
Rainbow Dash and rainbow Blitz were flying in circles in the sky, gaining speed.
"You think that will work?" asked Blitz.
"I hope so!" Dash answered.
The pegasi dived toward the battlefield at top speed. They were moving really fast, then dash shouted:
"Now!!"
Rainbow Blitz quickly moved to behind Rainbow Dash. She broke the sound barrier, performing her signature move, the Sonic Rainboom. Blitz did the same less than one second after her. Together, they performed the first Double Rainboom ever. The colorful waves reached the battlefield, sending many robots flying.
"Good work, ya two!!" cheered Applejack.
"That was amazing!!" shouted Pinkie and Berry at the same time.
But the break only lasted a few moments. Soon they were facing many robots once again.
"We can't keep fighting forever!" said Dusk. "We can get tired, they can't! And there's too many of them for us to defeat before not being able to fight anymore!"
"There's still one thing we can do!" said Twilight.
Dusk smiled and nodded. The two lavender unicorns touched horns and started floating. Suddenly, a big flash. When the strong light faded, Twilight had a Tiara on her head and Dusk had a crown.
"Nice tiara!" said Dusk.
"Cool crown!" said Twilight.
Both smiled and their accessories started glowing. Five necklaces appeared around Twilight and five belts appeared around Dusk.
"I think they need us!" said Butterscotch.
"Let's go, then!" said Fluttershy.
They unlocked the window and opened it, then glided toward the group. When they landed, the Elements of harmony flew to their respective owners.
"I'm not staying out of this one!" Soinc said, grinning. Suddenly the seven Chaos Emeralds appeared around him. Uing their powers, they turned into Super Sonic.
"Cool!" said Rainbow Dash, not daring to look away from Sonic,as if she would miss the most awesome moment of her life if she even blinked.
"Elements of Harmony..." started Twilight.
"...let's do this!" finishd Dusk.
The necklaces of the fillies and the belts of the colts started glowing and sent an energy wave toward their respective leader.
The star on Twilight's tiara and Dusk's crown started glowing. Both shot a beam of multicolored energy that hit Sonic. His eyes turned white and a huge explosion of golden light happened. It was really strong, forcing everybody and everypony but Sonic and the Elements of Harmony to shield their eyes.
Once the golden glow faded, Sonic was back to normal and only the users of the Elements of Harmony were there, their accessories gone. After a quick look around, they all noticed the robots were not moving and there was smoking comning out of them.
"I think you fried their circuits!" said Tails, landing.
"Their small metal brains couldn't handle so much awesomeness!" Blitz said, hoofbumping Rainbow Dash.
"Aw yeah!" she agreed.
"You did it!!" Cream shouted happily while bouncing.
"That was impressive!" Dr. Eggman said while smoothing his mustache with his fingers.
"They work together very well! This might be a burden in the future!" he thought.
