Highlights of Doctor Who: Ponified.

There was a pregnant pause aboard the Sycorax ship. A young mare by the name of Twilight Sparkle had just laid down the law with them, explaining in great detail why they couldn't conquer Equesrtia. She had made a resounding logical argument, going over ethics, Equestrian law, and even thrown in some jokes. It was the most important speech of her life.

Unfortunately, that was when they started laughing at her. The lavender unicorn exchanged glances with Spike.

That hadn't the reaction she had hoped for.

The Sycorax leader quieted his chuckles and brought him up to full height. "Did you really expect such a transparent ploy to work on me, little pony?" He asked in a deep growling voice. "We have your people in a death grip! Make your decision now!"

That's the problem, Twilight thought. So much has happened; I don't know what to do.

It had started just the previous day. Twilight and her friends were hanging out, just doing their thing when Pinkie Pie, for no apparent reason, ran in, wised them all a Merry Christmas, and passed out. She's been remained so even after they had moved her to Twilight's library. While that was still going on, they had received a new message: Aliens were coming to Equesrtia.

The aliens identified themselves as Sycorax, and wanted to take Equesrtia over for themselves. Some of their advanced agents had made to the planet ahead of the rest and attacked the library. Twilight assumed they were after the Elements of Harmony.

That was when Pinkie Pie had woken up again.

She mentioned several things during the whirling of activity that followed, like what was attacking them, (Ryrek! Their tree-robots! Cool, huh?) Disabling them in a matter of minutes from a device she cobbled together in her kitchen, (I'm naming it the Signal-Jammer-Inator! Because it jams signals and all gimmicky gadgets are Inators! Duh!) and the most shocking thing of all:

"I'm not a pony." Pinkie Pie said with a carefree smile. "I'm an alien!"

Then she passed out again. Just to be difficult.

The Sycorax ship made it to Equesrtia, and put every Unicorn under some kind of spell. Even the Princesses' were affected. Twilight was able to change Pinkie's machine into a shield that protected everybody at her library from the whatever it was. Unfortunately, the Sycorax had detected them, and some how teleported the entire tree into their ship. They had demanded that Twilight negotiate on behalf of her ponies.

The choice was this: Either half the planet would be killed by the spell, or a third would be sold into slavery.

Twilight weighed the decision carefully. On the one side, if she refused to surrender, she would be responsible for the death of several million ponies. On the other side, many would say that slavery is worse than death.

One allowed some to go free. The other allowed all to live a living death.

What could she do?

Just then, the doors to the library popped open, and Pinkie Pie casually strode out.

"Hi everyone! Did ya miss me?" She asked perkily. Twilight was too surprised to correct her into saying everypony. "I'm sorry, but you'll have to give me a sec" She turned around and faced Twilight. "Am I green?" She asked.

There was silence

"What?" Twilight was finally able to ask.

"Nevermind, I can check for myself." Pinkie glanced down. "Nope, still pink!" She giggled. "Oh, I can still giggle to! Good, I'm still me!"

"Who else would you be?" Spike asked.

"That's the problem, you see, I don't know." Pinkie looked contemplative. "Heck, I'm not completely sure who I am now. I was never this when I was Pinkie Pie, I was just, you know," She made a weird circular motion with her hoof. "Pinkie Pie."

Twilight had almost processed this. She was almost able to come to grips with the fact that her friend had gone crazy. Er. Crazier than normal, when Pinkie Pie turned back to the Sycorax and Twilight lost her ability to speak.

Pinkie Pie's Cutie mark had changed.

Before, it had been three balloons, but now A Golden Hourglass blazed brightly, almost glowing.

At this point, Twilight's brain just went 'screw this, your on your own' and left her gibbering and pointing at Pinkie and the other Aliens.

"Now, what have I missed?" Pinkie asked cheerfully. "Lets see: A Sycorax ship, obviously, and you've kidnapped two of my best friends. What are you planning on doing with us?"

The Sycorax leader exchanged a glance with his subordinate. "Every magical being on your pitiful rock is under our control, so unless-"

"Ooh! What's this?" Pinkie as pointing at the large red button that decided whether the ponies of Equesrtia lived or died.

"Get away from that, you fool!" The Sycorax leader bellowed. "Have you no common sense?"

"Of course not!"

The Sycorax leader face palmed.

"Thing is, I'm a bit excitable, and things I've never seen before make me soooooo excited! Like all the wires and glowy energy stuff underneath that big red button." Pinkie carefully stuck her tongue into the 'glowly energy stuff'. "On the downside," She said frowning. "This tech isn't very new."

"Of course not, foolish pony!" The Sycorax leader bellowed. "Our magic is-"

"Nothing more than a modified version of Harmonization generator." Pinkie interrupted. "Normally, this stuff locks onto and stabilizes ordinary energy signatures. It's used to fix power generators. All you did was modify it to make it work on magic. Since mystical energy is just ordinary brainwaves translated through a unicorn horn into other forms of energy, it placed any unicorn in range into a hypnotic trance. It's only good until the unicorn horns natural energy signature remodulates in response to the field pattern." She huffed. "Seriously, how dumb do you think I am?"

Stunned silence.

The Sycorax leader rallied himself. "Don't be ridiculous, little pony! We hold a third of your race under our thrall! You have nothing!"

Pinkie snorted. "Don't be silly! You can't hypnotize someone into killing themselves. Hypnotism is merely when the body enters a relaxed state and is submissive to outside stimuli. It doesn't turn of the brains sense of self-preservation." She paused, seeing the confused faces around her. "You can't hypnotize someone to death." She glanced at Twilight. "Seriously, isn't anyone getting this?"

Twilight snapped out of her confused state. "So you're saying that nopony is really in danger?"

"I said nobody, but ya. Now, what about your answer?"

Twilight looked confused again. Pinkie sighed. "Your speaking on behalf of Equesrtia, aren't you? Under article 3f of the Shadow Proclamation, it is illegal to enslave any part of a planet that has not surrendered itself to you, and G7 has some strict regulations about declaring war on pre-warp cultures. If you don't surrender, they will be legally forced to leave Equestrian airspace immediately."

Twilight blinked. 'YES! I mean, No! I mean…" she shook her head and turned to face the Sycorax leader. "Equesrtia does not surrender, and it never will! Do your worst!"

The Sycorax leader gaped. He spun around and loomed over Pinkie Pie. "You, You…pony! You have destroyed everything! In less than a minute! By doing nothing other than talk! I challenge you to a duel!"

The crowd gasped.

Pinkie Pie frowned. "Oh, really? Can't we be friends?"

"Friends?" The Sycorax leader spat. "With a pathetic life form such as yourself?"

"Okay, not maybe friends, but you don't have made everything worse. I beat you fair and square. You don't have to hurt anyone." Her eyes shown with sincerity. "Please. Just go."

"Your bluff is all to transparent!" The Sycorax leader drew his sword. "Now, tell me the name of the pony I will be executing."

"I'm not a pony." Pinkie said quietly. "And you won't be hurting anyone else."

The Sycorax leader laughed. "And why is that?"

The pink mares' mouth settled into a thin line. Her entire expression changed from one of compassion to one of condemnation. She spoke four words, four words that inevitable change the lives of whoever hears them.

"Because I'm the Doctor."

When dictating this to her diary, Twilight would say that the expression on The leaders face was one of the most interesting things about the meet. It went from absolute confidence to fear in less than a second. Pinkie, now known to be the Doctor, took another step forewords. In a dead serious tone she continued, "I'm the last of the Time Lords. I am the Oncoming Storm, the Breaker of the Black Guardian , and the destroyer of Worlds. You just tried to destroy my home. But I'm willing to over look that, if you'll just leave." The Sycorax looked a each other. "Seriously, that's it! Just run away! That's all you have to do."

The Sycorax leader hesitated. The Doctor took anther step forewords, until she was standing nose to nose with him. Her eyes blazed with a cold fury.

"I said: Run!"

When would be alien conquers gathered around in bars and to tell tales, one this Sycorax leader always made sure to tell was how he had been the one being to escape the Doctor's wrath.

How?

He was the only one smart enough to run.
