Porygon is the first known modern artificial Pokémon that was ever intentionally created. It was created by the Pokémon Lab according to a Pokémon Report found in Silph Co. In addition, its presence as a prize Pokémon in the then Team Rocket-owned Rocket Game Corner as well as Team Rocket's earlier control over Silph Co. suggests that Team Rocket was involved in its creation.
Porygon has a pink polyhedral body with a blue stomach, blue triangular prism feet, and a blue rectangular prism tail. Porygon has a pink, polyhedral head that ends in a blue beak and has hexagonal eyes. Porygon is made completely out of programming code. Built into this code is a Silph copyright protection preventing duplication through electronic means.
Porygon is a genderless species.
Porygon is shown with the ability to change type into one of its own moves or to resist the last move that hit it, using processes only it and its evolutions can know. These processes are known as Conversion and Conversion 2, with Conversion having the former function, and Conversion 2 having the latter function.
Porygon is also capable of changing its appearance using Sharpen, and it is one of the only Pokémon that can learn this move.
