Porygon2 is a rounded, pink, digital Pokémon that shows similarities to a drinking bird. It has a relatively flat bill and large, round eyes. Its legs are simple ovoid growths along its sides, and its tail widens towards the middle. Its bill, legs, tail, and underside are blue.
It was upgraded to work in space, although its inability to fly limits this ability. It is artificially intelligent, and is capable of learning new behaviors on its own, including information it does not need to know. As a result, it will sometimes perform motions or abilities that are not in its programming. It is generally found in computers or in labs and other buildings working with people. It can survive in a space vacuum, though cannot move very well in zero-gravity. Porygon2 and its evolutionary family, Porygon and Porygon-Z, are the only known Pokémon that learn Conversion and Conversion 2.
When released from a Poké Ball, Porygon2 will immediately use a powerful Tackle attack that sends opponents flying. The attack cannot be escaped due to the speed in which it happens but Porygon2 is harmless once the attack has finished.
Representing the next step in technological progress, this Virtual Pokémon is a higher-powered version of the man-made Pokémon, Porygon. Compared to the sharp edges of its relative, Porygon2's body is extremely smooth and rounded. In battle, it utilizes a special move called Conversion 2 to alter its type.
This Pokémon was unavailable prior to Generation II.
Porygon2 is the only Pokémon with a numeral in its name.
In the Generation II games, it is impossible to return a nicknamed Porygon2 to its species name, because the character 2 is not available as a character for nicknames.
Porygon2 is the only non-fully evolved Pokémon that:
Has evolved by trading.
Was introduced after the generation of its pre-evolution.
Like Porygon, it is based on a bird (possibly an origami crane) made with more advanced 3D computer graphics software than the first Porygon. The head looks like a duck. It also resembles a drinking bird, especially in the 3D games, where it makes the same movement as one. The change in form by evolution from Porygon to Porygon2 represents the concept of subdivision in 3D computer graphics.
Porygon2 is a combination of polygon and 2, with Porygon being a corruption of polygon. 2 may be a reference to software versioning, as it is the second "stable release"—an upgraded version—of Porygon.
