I was walking through a cave with shimmering walls. The floors were slick with some viscous mess and trudging down the path was somewhat difficult. I rounded a bend in the path and found myself in the dark, empty maw of a great cavern. The darkness was so great that it enveloped even the path behind me. My mind erupted with searing pain as some psychic forced engraved an image of what lay before me into my brain. Upon a slippery mass of writhing tendrils sat a great statue. Deformed and cruel, it held a shape roughly that of a man, with disproportionately large head and digits, and a thick tail hanging below it's waist. The white hot image searing itself into my memories forced me to my knees, and a shook, incapable of dealing with the horror before me. I watched in a stupor as the statue started to convulse, and shake itself to life. It was no statue, but a living monster! I was frozen in fear as the creature tore itself from its writhing throne and floated slowly towards me. I felt my balls vibrate, bringing me out of my trance. The world flashed around me and I jumped to my feet and reached for my belt, and I heard my pokedex scream, "A wild Mewtwo appeared!"
