In the months leading up to its release, many fans were hoping that their favorite monster would be in Pokémon Legends: Arceus, but the inclusion of one fan-favorite — Porygon — raises some questions about its origins. Porygon, the Virtual Pokémon, is one of the 242 creatures included in the latest Pokémon title, and one of the rarest to boot. The game's setting means that Porygon's inclusion has unintentionally sparked a huge mystery about where it came from, as it's flung into the past by space-time distortions.
Porygon is a Pokémon made from computer data. It is a living program, one that can cruise cyberspace with ease, and materialize just as easily into the real world to interact with non-data entities like humans and other Pokémon. It's both one of the last that fans expected to see in Pokémon Legends: Arceus' Pokédex and one of the more rumored ones in the time leading up to its release, especially since Voltorb gave a glimpse of what an artificial Pokémon would look like in an ancient setting. Unlike Voltorb, however, Porygon was created on purpose, by humans in a lab, and therein lies its mystery.

It's far from a certainty, and it's possible that it's only true for its final evolution, Porygon-Z, and not the original or Porygon2. How the developers missed the question that this Pokémon's inclusion would raise is baffling, but they could be planning on doing something that explores this very topic in the game's future
