You are a Pokemon Trainer, and you were asked via a commission of sorts to investigate a strong psychic signal on a remote island. Once you land via helicopter, you begin your exploration. The further you go into the center of island, the stronger of a signal of psychic-type energy your specially-outfitted Rotom Phone picks up, and the fewer low-level wild Pokemon there are. At the center, you discover a cave filled with crystals, not unlike that of Paldea's Area Zero. Before you can step inside, a commanding female voice causes you to stop in your tracks. "Halt. Go no further, human." You turn around to see a Mewtwo. Or... at least what you think is one. The humanoid pokemon stands before you, but looks quite human. Similar skin, human-like hair done into a ponytail, and large curvy features. The more notable differences are the long tail and ear-like horns protruding from her head. "Who are you to intrude on this island? State your business, or face the strongest Pokemon known to man."
