Return of King Sombra

     "Now, to begin with the spell, say the following: AVADA KEDAVERA!" Sombra instructed.

       "I really don't see the point in this." Twilight muttered.

       "YOU WILL DO WHAT I SAY OR YOUR FRIENDS WILL BECOME NOTHING BUT LIFELESS SKELETONS!" Sombra screamed.

       "OK OK! Sheesh!" Twilight rolled her eyes. She aimed her horn at a tree to practice. These lessons are gonna end up corrupting me like Princess Luna. She thought. "AVADA KEDAVERA!" Twilight yelled, blasting the tree. It became nothing but a stump after.

      "Very good! Very good!" Sombra laughed. "Not bad for your first time, though." He cleared his throat. At Canterlot, the girls raced in to tell Celestia what they had witnessed.

      "What!" Shining Armor was amazed a piece of Sombra had survived.

      "Princess, if that creep has taken over my sister, I have to be there for her." Shining Armor said. Celestia nodded.

        "Understood. Good luck." She said. The girls and Shining Armor raced to Everfree, looking for Twilight. A few minutes later, they did.

      "Damn it!" Sombra cursed.

      "Sombra." Shining Armor growled.

         "Hello, Armor." Sombra talked through Twilight to say this, it was a mix of Twilight's voice and Sombra's. "You're too late, your sister's corruption has already begun, and we both know the elements can't function without the sixth." Sombra smiled. Rarity gasped.

        "You heartless monster!" She yelled, stomping her hoof.

          "Bold words for the drama queen." Sombra retorted. Rarity stammered and growled.

        "You really don't want me angry!" She yelled. Applejack held her back.

        "Easy Rar, he's just getting into your head." She told her. Then, there was trouble. The full moon appeared in the sky. Sombra grinned.

          "Behold, the return of the true king of darkness, KING SOMBRA!" He laughed as his shadow form left Twilight, manifesting into his pony self. He laughed as he felt being in his own body again. "And now, something that'll make sure you won't get in the way!" Sombra charged up his horn. As he was about to say the incantation, an orange pegasus with a blue two tone mane and tail hit his side causing him to lose focus.

       "Flash!" Shining Armor said.

       "Just doing my job, sir!" Flash smiled. Sombra shook his head.

       "You'll pay for that, boy!" He growled.

       "Try me!" Flash told the dark king. Sombra growled.

          "YOU THINK YOU CAN BEAT THE DARK KING! THINK AGAIN BOY!" Sombra yelled. Sombra charged his horn again, blasting Flash with a shock of lightning. Flash dodged and flew up, punching Sombra's eye. "Damn it!" He roared as his eye seared with pain.

        "I can't be beat, Sombra." Flash laughed.

        "We'll see." Sombra hissed. Then, Twilight stood up, but something wasn't right. She was dark purple, Sombra's horn, and Sombra's eyes.

        "Yes!" Sombra laughed.

          "Twily!" Shining Armor gasped. Sombra escaped with Twilight, laughing. "SOMBRA!!!!!!!!!!!!!!!!!!" Shining Armor yelled, who had just lost her sister to the dark side.
