Considered across Pokémon generations to be one of the most popular Pokémon of all-time, Mewtwo's adoration by fans hasn't decreased one bit since its original appearance in the first games, and, more memorably, in the first movie. But more recently, the moody Pokémon we've all come to love has resurfaced in a rather different form, which has led to a lot of confusion about whether this is in fact the same Mewtwo, or a copy of the copy.

The Original Mewtwo

It's no secret that Mewtwo is extremely loved by the Pokémon community. This dates back right to his appearance in the first movie, which won everyone over instantly with its dark origin story for the cloned Pokémon. Mewtwo was created in a lab experiment by humans who wanted to create the world's strongest Pokémon by cloning the Mythic Mew's DNA. Out of this unethical deed was born Mewtwo. Understanding the injustice and cruelty with which it was created and treated, Mewtwo destroyed the lab in which he was created, as well as the people who created him. Out of this grew his distaste for humanity -- a distaste which was partially extinguished thanks to Ash and friends, their Pokémon, and of course, the adorable Mew.

Although Mewtwo in the games is genderless, like all legendary and mythical Pokémon, he's referred to as a "he" by fans due to being played by a male voice actor in the original movie. Mew, although genderless, is often thought of as being female. This gender opposition also created an interesting contrast between the two, as you had an original vs. clone, female vs. male, and playful and trusting vs. serious and distrusting.

Mewtwo's story continues in the movie Mewtwo Returns, which was just as dark and serious in tone as the original film. The same Mewtwo was also featured in the CG remake of the first movie,  Mewtwo Strikes Back—Evolution.

The Gender-Flipped Mewtwo

In the more recent movie, Mewtwo -- Prologue to Awakening, Mewtwo returns, except this time, a few differences puzzled fans. For starters, this Mewtwo's original creators seem to be still alive; it doesn't seem to recognize Ash, and it's... female? The Mewtwo from Mewtwo -- Prologue to Awakening has a female voice actor, and although Mewtwo in the games is seen as genderless, that combined with all the previous points has led fans to assume that there might, in fact, be two Mewtwos.

Another reason to believe that this might be a separate Mewtwo from the original is the fact that this one can Mega Evolve in Mewtwo X. X, here, could well refer to the X chromosome and could serve as confirmation. But Mewtwo can, however, also evolve into Mewtwo Y in the movie, so that aspect of the theory alone isn't enough to be a decisive factor.

Although the idea hasn't been officially deemed canon by GameFreak, many fans have come to simply accept the possibility of there being two Mewtwos. There are also fan theories suggesting that the "female" Mewtwo comes from an entirely separate timeline of the Pokémon anime. This wouldn't be the first time that the alternate timeline within the Pokémon universe theory has been brought up, as many fans believe that it would explain things like Dynamax Pokemon or Mega Evolution.

Either way, male or female, it seems as though movies with Mewtwo won't be ceasing anytime soon, as the famous legendary Pokémon is as popular as ever, whether in games, movies or even in Pokémon GO.
