In a surprising move, the current Pokémon TV anime (called Pokémon Journeys in English and simply Pocket Monsters in Japanese) recently brought back the original super legendary, Mewtwo. And not just any Mewtwo, but the one who debuted over 20 years ago as the Viridian City Gym’s trump card. Mewtwo is my favorite character in all the anime, so there’s a personal thrill to seeing its return, but there’s added significance as well: the continued acknowledgement of the canonicity of events in and connected to the first film, Mewtwo Strikes Back, and an emphasis that what has happened over the anime’s long history still matters.

The Pokémon anime tends to play a little fast and loose with its canon, resulting in strange discrepancies, especially when it comes to the divide between the films and the weekly series. Aside from Mewtwo Strikes Back, whose plot ties directly into the TV anime, it’s always unclear—likely intentionally so—whether the events of the other movies actually “happened.” This isn’t unusual when it comes to films based on popular anime—nearly all the Dragon Ball Z movies are non-canon, and the popular movie-only character Broly had to be reintroduced into that universe in a canonical entry, Dragon Ball Super: Broly. 

In the world of Pokémon, this has meant that, despite the fact that certain legendary Pokémon are meant to be the only one of their kind, Satoshi (Ash Ketchum) has encountered multiple versions. After he helped a telepathic Lugia save the world in Revelation-Lugia, he would later encounter a different one that could not communicate psychically and, in fact, was trying to raise a child (Lugia is not supposed to be able to breed). Even Mewtwo, whose whole story is that it is a one-of-a-kind artificial creation made to be unmatched in combat, would see a second distinct version show up in the 16th movie.

In the recent episode, there is no mistaking that the Mewtwo seen is the original. When it first appears, Mewtwo slowly descends as ominous background music from Mewtwo Strikes Back and the Mewtwo Lives TV special can be heard. When Mewtwo speaks, its gruff yet soulful masculine voice is that of the original actor, Ichimura Masachika, as opposed to the feminine voice of the 16th movie Mewtwo’s Takashima Reiko. And when Satoshi and Goh lay eyes on Mewtwo, their reactions couldn’t be more different: whereas Goh is shocked by seeing something unfamiliar, Satoshi and Pikachu immediately recognize the Genetic Pokémon and even say its name. 

However, it’s not as if Mewtwo and Satoshi start to recall their two encounters. Mewtwo doesn’t even say anything about already knowing Satoshi, and Satoshi doesn’t bring anything up beyond that initial recognition. While this might be frustrating to fans who’d like to see a more concrete nod to Mewtwo and Satoshi’s connection, I think the current anime is trying hard to balance a lot of different paradoxical elements that exist within Pokémon and Satoshi himself. He’s somehow both the veteran with years of experience under his belt and the plucky young amateur who has much to learn—perpetually 10 years old for over 20 years. Satoshi’s many adventures have happened (including at least one film), but he’s also still meant to be an audience-representative character for young viewers tuning into the anime for the first time, even as Goh fulfills a similar role (though his character is closer to a scholar or researcher). Furthermore, by having Satoshi not say much, it reinforces the idea that he hasn’t let his previous experiences get to his head. A similar moment happens in the second episode of the current series, where Lugia speaks to Satoshi (and only Satoshi) telepathically, hinting that this one might just very well be the one we see in the second movie.

Trying to fully reconcile the Pokémon anime canon would be a foolish endeavor because it’s only as consistent as it needs to be in any one moment. Satoshi is forever a challenger, even as he wins championships. But given what the anime is trying to be, a long-running series that wants to feel both familiar and new at the same time, it’s not a bad place to be. And seeing the original Ichimura-voiced Mewtwo n the year 2020 is a nostalgic and thrilling experience. Mewtwo’s appearance speaks to the idea that the past of Pokémon still matters even as we continue to move into the future.
