"Yes, Doctor, we are back and this time we will not fail in our mission! Unlike the tenth battle fleet did." the strange, creepy looking potato shaped creature said.

"Well, why are you here this time?" The Doctor asked.

"It would be unwise to tell the enemy our strategy." it said.

"Yeah, I knew you were going to say that, another one of you said that when you were up to that A.T.M.O.S business." The Doctor said.

"What's ATMOS?" Spike asked.

"They used a system to put in cars, cars are something humans use for transport by the way, and when activated lets out clone feed so they could turn the earth into a clone world. A.T.M.O.S stands for Atmospheric Omission System by the way, but back to topic. But they don't know who you are, so tell them since you're trying to burn their hole world." The Doctor said as he pointed at the other ponies.

"I am a Sontaran, from the planet Sontar and we want your planet." the Sontaran said.

"You look like a baked potato with arms and legs!" Spike laughed.

"I know right, everyone says that though. They don't listen though." The Doctor said.

"Your social interaction will cease!" the Sontaran demanded.

"Why don't you have a name? Most Sontarans have names." The Doctor asked.

"Only Sontarans who have battled and won wars get names." the Sontaran explained.

"Why have you not won any? Because I was around?" The Doctor teased.

"No! As you know, Doctor, Sontarans are born in batches and immediately put into battle fleets. We are a brand new battle fleet, ready to crush this primitive planet!" the Sontaran shouted.

"I have another other question. Why are you not pony Sontarans? Because everything in my universe that is humanoid, is a pony in this universe. So why aren't you?" The Doctor asked.

"We are from your universe." the Sontaran explained.

"What?!" The Doctor said in shock.

"When you came into this universe, you opened up a rift in space, once again, we detected it and followed through. And we Sontarans know for certain that we were not the only creatures to follow through after you did." the Sontaran explained.

"Ok, another question, what is stopping you from being in the form of a pony?" The Doctor asked.

"Dimensional form disruptors! If the other universe or dimension has a different form, we activate them and they stop our forms from changing." the Sontaran explained.

"Hmm, I could use with one of those. But back to your plans. You need Princess Celestia to make the sun go into a supernova, correct?" The Doctor asked.

"That is correct, Doctor!" the Sontaran replied.

"Well, you can stop and leave because we have Celestia and we have deactivated the control chip you put inside her mind!" The Doctor said.

"No, we will not go, because you haven't outsmarted us yet, Doctor." the Sontaran replied.

"What do you mean? We have Celestia and you no longer have control over her, so what else can you do to destroy Equestria?" The Doctor asked.

"We only needed Celestia so we could destroy this planet with the sun undetected. But since you've regained control over her, we will have to do it from our ship!" the Sontaran explained. He turned to his battle fleet. "Power up the system, gain control of the sun, make it supernova, and burn Equestria!"

The sun started expanding again, the planet was getting hotter and hotter by the second.

"Death to Equestria for the glory of Sontar! We shall take this small and useless rock of a planet and turn it into part of the great Sontaran empire!" the Sontaran chanted.

The Doctor put a smile on his face.

"What is it, Doctor why are you smiling?" the Sontaran asked.

"Because I've worked out your plan!" The Doctor smiled.

"What? You couldn't have!" the Sontaran replied.

"You wanted to be undetected so nobody would find you, especially me, so you gained control of Equestria's most powerful princess to do it for you, but if she failed you would do it from your ship anyway. You make the sun supernova and burn Equestria, destroying all life on the planet, making it free for the Sontaran empire to fill with clone feed and create a new army to invade and conquer this universe!" The Doctor explained.

The Sontaran looked at The Doctor and was surprised.

"You are very good at working out stratagems, Doctor! You would be good in the Sontaran empire." the Sontaran said.

"No thanks, I prefer the good, not the potatos. But I will stop you!" The Doctor said.

"How? you don't even know where we are, good luck! Cease transmission!" the Sontaran shouted.

The monitor turned black with no image. The Doctor started to think up a plan immediately. Celestia woke up.

"Ugh,. What happened? Why have I got a duck impaled through my horn?" Princess Celestia asked.

"Equestria is being threatened by a bag of potato's from outer space, mashed potato's when I'm done with them." The Doctor explained.

"Oh, Doctor, Twilight, one thousand years later? I'm guessing this is where The Doctor promised to take you in the T.A.R.D.I.S?" Celestia asked.

"Yes, Princess." Twilight replied.

"What were you saying about potatos? I wouldn't mind one, I'm hungry." Celestia asked.

"They're not really potatos, they're called Sontarans and they are from my universe. They plan to destroy Equestria with the sun, they took control of you to do it, but you wont remember that." The Doctor explained.

"Well we need to stop them, Twilight go get the Elements Of Harmony!" Celestia said.

"Princess, the Elements Of Harmony won't work against Sontarans, but don't worry, I've got a plan." The Doctor smiled.

"What?" Luna asked.

"I have a teleport that can teleport us to the Sontaran ship, when I find its position." The Doctor said.

"What? Are you insane? They'd shoot us on the spot." Spike said.

"When we get on the ship we can get one of those dimensional form disruptors, make ourselves look like Sontarans, then we can turn off the systems that is making the sun supernova and then we can stop the Sontarans from taking over." The Doctor explained.

"Good plan, lets get started!" Twilight replied.

"Just a warning, It will be dangerous!" The Doctor said as he warned everypony of the uncertain doom that lies ahead. Next Chapter: Defeating The Potato's Estimated time remaining: 10 Minutes
