Once upon a time there was a man named Bob who had magical powers. They weren't just ordinary magical powers, they were magical powers that involved trolling. Only the Avatar master of all 4 elements could stop him.
The Avatar met Bob and said to him, "I must kill Bob."
Bob said to the Avatar, "No, you are Bob." The Avatar turned into a zombie and he had to fight himself. Bob used his magical trolling powers on the Avatar. He said, "I will use my power, my BOB POWER!" And then later, Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! Explosions! BOOM! SWAG! PASSION! THE END
Then Bob left the movie theater and said, "Never read a bad fanfic."
