Pikachu

You will be hard-pressed to find many mascots more famous than this electric mouse, much less a more famous Pokemon. Pikachu is the Pokemon, and Niantic makes sure that we know this with a plethora of hats, costumes, and outright alternate formes that are different from the normal version. However, do not be fooled by these unique variants! Pikachu has no actual utility, and an investment in it is like someone purchasing a mine rich with fools gold!
