Megacorn glared right back. "No," she said, "I realize now that Pinkie Pie was what I needed all along to aid my conquest. You cannot destroy her."
"Then it appears that we must do battle," Shadow said, "but I warn you, my powers over reality are nothing to sneeze at!"
Megacorn raised her plasma arm cannons. "Stand down, Hedgehog," she said.
Shadow rushed forward, faster than Megacorn could percieve. Then with a powerful karate chop, sliced off the barrels of Megacorn's arm cannons. Megacorn tried to fire before she had realized what had happened, and a huge explosion ensued. Shadow's golden aura blocked any of the flames from reaching his flesh and continued on toward Pinkie Pie's cupcake castle.
Megacorn lay defeated in the road, not dead, but it would take her time to recover. "I'm sorry, Pinkie Pie," she said, "I have failed you, my dear friend..."
Super Shadow appeared before Pinkie's castle. "Pinkie Pie! I have come to kill you!" he shouted.
"Wait, Shadow!" Pinkie called out, "You are making a terrible mistake! I have learned much since I became an alicorn princess. I have seen the other realities and how they all connect. You and I are counterparts in the cosmos, you cannot harm me without harming yourself!"
"Why should I trust you?" Shadow yelled, "Bill Cipher offered me a chance for my revenge, do you think I'm going to pass that up?"
"Do you really think that Bill Cipher cares about you?" Pinkie countered, "He's only using you to get back at me, If you die in the process it only negates his side of the bargain."
Shadow raised his fists, ready to attack.
"Stop, Shadow!" Pinkie pleaded, "If you strike me, it will create a singularity in spacetime, a point from which we can never go back!"
"I'm done listening to you!" Shadow shouted, and then he lunged forward. He aimed his blow right at Pinkie Pie's heart, but as soon as their bodies made contact there was a flash of light and all of reality tilted.
Pinkie Pie and Shadow had fused into a singular being. Pinkamena Pie, stood alone in the darkness holding a knife over herself.
"I have to do this!" she shouted, "I have to end it for the sake of revenge!"
"No!" she called again, struggling with herself, "If I die, then Bill Cipher wins and my revenge will go unfulfilled!"
"But without my revenge!" she called again, "there is no point to living, I have to do it!"
Then with a swift blow she stabbed herself in the chest. The light faded from her eyes, as blood poored out, and she roll over on the ground, dead.
The End.
