Biology
Porygon is a Pokémon made completely out of programming code. It has a pink polyhedral body with a blue front, blue triangular prism feet, and a blue rectangular prism tail. It has a pink, polyhedral head that ends in a blue beak and has hexagonal eyes. In 3D games, such as Pokémon Stadium, it can detach its limbs and head from its torso. According to its Pokédex entries, it has copy protection built into its code, preventing duplication through electronic means. It was created 20 years ago at the Pokémon Lab on Cinnabar Island using the latest state-of-the-art technology of its time, so many of its parts have since become obsolete. It was the first artificial Pokémon to have ever been created through computer programming.

Due to its man-made origins, Porygon does not need to breathe or eat, though it can still accept food if given. It has the ability to convert its body into digital data, allowing it to travel through cyberspace. Recently, it has become more helpful inside cyberspace by searching for any suspicious data that exists. Some believed Porygon has the power to potentially travel in space despite the species not displaying that ability yet. Porygon has two signature moves, Conversion and Conversion 2, and in the past it also had Sharpen for a signature move. It can use Conversion to change its appearance to mimic another Pokémon's and has also demonstrated the ability to change color for camouflage. Because it is man-made, it is generally found in computers or in labs and other buildings where people work.
