Porygon2 is a normal type pokemon that is, unlike porygon, a circular duck that can sort of be helpful.
It has never appeared in the anime, meaning nobody cares about it. It can travel through cyberspace. Like Porygon, it can change it's type. It was made by the most evil Pikachu ever known, who stole Porygon from good people. You can evolve it if you want a duck infected with a virus instead of a circular internet duck.
