You have only killed my decoy, my good lad. I travel to Equestria to gather the Mane Six and the Elements of Harmony. I travel to your location in the year 3000. I have the Mane Six use the Elements of Harmony to take away all evil from your heart, making it impossible for you to try and hurt me again. I then write your name in my Death Note, specifying to kill you instantly. Finally, I take your corpse into the TARDIS, transport to a black hole, and throw you in, destroying you body completely.
