Halley's comet

         "She is a very qualified candidate your highness,". Celestia glanced at the sergeant with a concerned look.

      "She has the strength of a bunny rabbit and the courage of a mouse. She cannot operate our weaponry, or charge in the face of danger. Her genetics match up, sure, but her family is infamous for insanity and weakness, and lack of skills. I remember her great grandfather died without a cutiemark. Obviously not war material, and trust me sergeant I have lived for a millennia and experienced the most crude of wars and have seen ponies like her go to war. It did not end well for themselves nor the citizens of Equestria. She should just stay home and tend to her farms."

     "Yes, but m'am, times have changed, we have developed newer technology, newer weapons, weapons that can only be operated by ponies such as herself if our calculations are correct, and this is no ordinary war, this is not of Equestria, or of our entire planet either. Chances are to be taken at the best opportunity."

     "Do you even think this is a war? How can you be so sure? They are possibly a threat. I have done the math myself, there is a 8.0423% chance that they are going to interact with our planet. Nothing to change the course of ones destiny over. And certainly not something to turn a pony into a weapon over either. As far as we know, they don't even know we exist."

     "But that's the thing princess Celestia, what if they do? What if they try to kill us, wipe us out? The security of Equestria has been based on precautions. Remember the changeling invasion? It was simply a rumor that changelings had wanted to invade, and because we took this rumor so seriously, Canterlot would have been destroyed if it weren't for the ponies who asked the question 'what if'. What if there is an invasion? That was the question that saved Canterlot, that is the question that can save us now."

     "Actually it was twilight and her friends that saved Canterlot"

     "But if it was because of the precautions would you be just as inspired?"

     Celestia looked at the sergeant with a look that questioned his legitimacy before playing his little game. "Sure, I guess... But I still don't think drastic measures are required."

     The sergeant looked up at the princess and sighed. "Princess, I figured you would say that. There's something I would like you to see. Bring it in Sweetdrops!" The doors opened suddenly and a female unicorn entered the room carrying with her a crystal. She placed it on the ground with her magic and a bright flash filled the room. A picture emerged from the crystal giving a holographic image of what at first seemed like a crater with smoke emitting from the center.

     "Play the video," said the sergeant as he gestured the unicorn. She nodded and the image started moving.

     Ponies were gathered around the crater whispering to each other when suddenly a strange energy emerged from the smoke to form a bipedal figure that was composed completely of some weird energy.

     Plasma flickered violently around it. The figure could be described as a werewolf on fire expect there were no specific details or features that could be pinpointed at a given time, simply an intense electrical being taking a form that was cross between plasma and solid.

     It jumped high up into the clouds until nopony could see it an then dropped right in front of the camera crouching down and producing an extremely high pitched sound that was almost unnoticeable it was so high. The pain it inflicted on every ponies ears was noticeable however because the camera showed nearby ponies ears bleeding a little. Then fireponies got a hose and sprayed the creature down.

     The creature reacted violently to this and hit one of the ponies into the crater. Eventually there were dozens of hoses spraying down the creature, and it gave in and the plasma dissipated to show a weird disfigured rock that had holes in it like Swiss cheese.

     The video ended.

      "The rock was sent from the alien object and crashed down somewhere near philidelphia. There were 8 casualties. Most died from the immense sound wave, others from the monster itself."

      Celestia was silent. Not exactly sure of what she just saw.

      "M'am, if I can also...." He was interrupted as Celestia lifted up her hoof and nodded.

     The sergeant nodded in return and said to the unicorn, "tell the others that project C.O.M.E.T has been approved, and that we should start operations immediately."
