Although technically a virtual, manmade Pokémon, Porygon-Z does have a physical body. Its head is fuchsia and ovoid in shape with a short, blunt antenna protruding upwards and a blue bill similar to that of a duck. Its eyes are yellow and have black rings, similar to a bulls-eye. The head is completely detached from the body and floats slightly above it. Its smooth, ovoid body is fuchsia with a blue ring connecting its arms. Two arms are loosely connected to their upper body and, other than their blue color, have no features. The tail is also blue and featureless but slightly resembles a paddle.
Porygon-Z was given additional software in order to increase its abilities. The initial idea was to give it the ability to travel through alien dimensions, though it did not work as planned. Instead, the Pokémon began showing highly erratic, unstable behavior and twitchy movements, making it difficult to work with for research. As a result, it is believed the experiment to create Porygon-Z was a failure. This has been attributed to the incompetence of the engineer improperly updating its programming. Because the update caused instability, academics can't seem to agree on whether Porygon-Z should be considered a true Evolution of Porygon2.
Porygon-Z appears as a trophy exclusive to the 3DS version of the game.
NA:Porygon is an artificial Pokémon created by humans. Given an Up-Grade, it becomes Porygon2. Then another mod turns it into Porygon-Z. You'd think two upgrades would make Porygon-Z the perfect Pokémon, but actually, the Dubious Disc used to make Porygon2 evolve seems to have introduced some bugs. Maybe a patch is in the works?

You'd think two upgrades would make Porygon-Z the perfect Pokémon, but actually, the Dubious Disc used to make Porygon2 evolve makes it a bit glitchy. Maybe there's a patch in the works...
This Pokémon was unavailable prior to Generation IV.
Porygon-Z and its pre-evolutions are the only Pokémon where all three members of the evolutionary line can learn both Hyper Beam and Giga Impact, this due to the fact that all three were fully evolved Pokémon at the time of their debut.
Porygon-Z may be a corruption of polygon and the letter Z (referring to either the Z axis in a 3D coordinate system or that fact that it is the final stage in its evolutionary line since Z is final letter in the Latin alphabet).
