Description: When Porygon2 was upgraded into Porygon-Z via the Dubious Disk, glitches soon became apparent. Using the power of Mega Evolution, a system update/patch was created in the form of a Mega Stone, thus creating Mega Porygon-Z. With its patch, Porygon-Z can now fully implement its original programming and travel to and from cyberspace at will using the portal that floats behind it. It can even travel to alien dimensions. It has increased Special Attack, Defense, and Special Defense.
Mega Stone: Porygonzite
Mega Ability: Analytic
Trivia: In a callback to its name, Mega Porygon-Z’s shape is that of a Z. The portal behind it can be opened an closed based on convenience in battle, and a scene is shown of it opening when Porygon-Z first Mega Evolves. Rumor has it that Devon Corp. experiments with Infinity Energy are the origin of Porygon-Z’s Mega Stone.
