the Doctor was quickly piloting the TARDIS, at the same time he cobbled together pieces of equipment that had been lying around

One he had gotten from a dalek eyestalk, that was the emitter, it was a light green. The next piece was a bit of controls salvaged from a damaged dalek husk

the handle was received from some bits of the broken TARDIS, as was the radiation cap

Now the TARDIS had then provided him with a new sonic core, which he inserted into the frame, finally the TARDIS had made it a fully functioning sonic screwdriver

"We're coming in to land!" the Doctor warned Midnight

[…]

"No Doctor to help you, not so tough are you?" the Univore was loving the degrading feeling he imposed on Twilight Sparkle

*WHOOSH WHOOSH*

"What!?" the Univore spun around

A blue box crashed into the room, smashing the glass window depicting the defeat of the Univore

Once it had settled on the opposite side of the room, the doors opened

The Doctor stepped out, wearing a new gray blazer, his bowtie was a mix of blue, and navy and a lighter gray, it complimented his new gray fedora nicely as it matched the band around the top

"Impossible!" the Univore declared

"That's two impossible things we've seen today." the Doctor retorted

"Doctor, is it really you?" Twilight asked

"Why wouldn't it be?" the Doctor arched an eyebrow, "Well I do suppose he happened but at the same time you should have known from the start he was a fraud."

"Why the fedora?" Twilight managed to ask

"It's cool" the Doctor grinned, "Fedoras are cool."

Midnight then exited the TARDIS, at the same time Starlight stood next to the Univore

"I see we are at a standstill" the Univore said

"Answer me this, the walls of the universes are breaking down. Therefore I was able to pass through them with the TARDIS, but it wasn't just two universes, it was multiple ones, You're planning on destroying all of them." the Doctor stood up straighter, "My question: Am I right?"

The Univore seemed unimpressed, "Yes you are right."

"Then it isn't just my universe, but all of reality is in danger." the Doctor turned to Twilight, "Where's the rest of your friends?"

The Univore chuckled to himself

"You didn't" the Doctor stood rigid

"Oh but I did"

"What did he do?" Twilight asked

"The Univore feeds on universal building blocks" the Doctor explained, "And it looks to me like he's had quite the snack."

Twilight blanched, Midnight's jaw dropped and Starlight looked alarmed

"What are you going on about?" Starlight asked

"That's not your Doctor" the Doctor said, "That's a creational being who feeds off the energy that the universe is made of."

"Then what happened to my Doctor?" Starlight arched an eyebrow

"My guess is that he killed him and stole his form" the Doctor answered, "Not the body, it wouldn't be able to hold for long."

Starlight calmly walked up next to the Doctor

"You left me to die, you hurt my friends, you kill billions every time you feel peckish"

the Univore cracked a smile

"However, I am willing to let that go, if you restore Twilight's friends and leave." The Doctor held his chin high, "Do that, and I won't have to stop you."

The Univore lifted his arms, the Doctor felt his pulse quicken, purple sparkles began to fling and cling to assorted items in the room. Then they began to disintegrate, the Doctor could see the void from where he stood

"RUN!" the Doctor ordered

All of the ponies in the room sprang into action, Starlight Midnight and Twilight rushed towards the TARDIS

The Doctor took one last look, the Univore laughed in victory as Celestia's body vanished

"Luna! Don't-" the Doctor was too late

A roar of anger erupted from the princess of the night as she flung herself towards the Univore, getting the full blast of energy in her face, she was gone in seconds

Twilight shouted for the Doctor to get inside, which he promptly proceeded to do, but Twilight exited the TARDIS

"What are you doing?" Midnight called over the cries of panicked guards

"Thank you Doctor, for everything." Twilight said, "But if my friends and family are dead, what's left?"

"Listen to me Twilight" the Doctor said, "I can fix this somehow, I can-"

"No" Twilight lifted a hoof, "I have to do this."

The Doctor didn't want to watch, but he wanted to let Twilight have her last moments

Twilight walked up the the Univore, and defiantly stuck her chin out, the Doctor closed the TARDIS doors

"Right then!" the Doctor rushed up to the console, taking off

"What do we do Doctor?" Starlight asked

"The Univore can't be sealed away" Midnight added, "There's only one way we can truly defeat it."

"There's only one of its kind" the Doctor said, "That'd be genocide."

"You can see why I purged her" Starlight cast a glance sideways

"Here's a question, what is the purging?" the Doctor crossed his arms, "I never got that."

"Well it's just that" Starlight shrugged, "You purge any alternate personalities and/or minds in order to keep your mental state stable."

"Well" the Doctor sighed, "I was hoping it could help me come up with a plan, but it evidently did not."

"You're just not as good as you used to be huh?" Midnight smirked

"As good as I used to be..." the Doctor snapped his fingers, "HA!"

"What is it?" Starlight looked excited

"I can restore time" the Doctor said, "The Univore damaged it, but I can cross my timeline, the Reapers will come in and clean up the mess!"

The Doctor ran around the console, pressing buttons and flipping switches

"How is time damaged anyway?" Starlight asked, "It isn't just something you can go touch."

"Good question" the Doctor commented, "Whenever time is damaged it begins to restore itself, but the Univore is preventing that in a small area. Now I can go outside that area and get the reapers to clean up time, we can't go back to the future as time reverses whenever it deletes itself."

"Are you sure this will work?" Midnight questioned

The Doctors expression said it all

"Right! We've landed!" the Doctor held out his hand, and threw open the doors
