Mewtwo is the result of genetic experiments on the legendary Pokemon Mew, created to be the ultimate fighting machine. As Pokemon #150, Mewtwo represents the pinnacle of artificial Pokemon creation and has psychic powers that surpass almost every other Pokemon. The card's "Psychic" attack scaled with the opponent's energy, making it incredibly powerful late game. Mewtwo's tragic origin story and immense power make it one of the most compelling Pokemon in the franchise.
