Porygon2 was made from slightly different manufacturers than Porygon, as Porygon was made mainly by Pokemon Lab of Cinnabar, who developed Porygon with the help of scientists of Silph Co., an affiliate of Pokemon Lab. Porygon2 was made solely by Silph Co., in order to see if the capacity of Porygon could be expanded while subtracting the amount of space the new prototype would take up. Since Porygon itself could be edited and tested through computers, a program was developed to update Porygon's appearance and the parts that made it up. Once the program was developed, they figured out that it took up around 2,317 MB, so they had to create a special disk for the program. This disk was encased in a crystalline box, so the disk would not be harmed, and so the whole item could be transferred electronically along with the Porygon, so that the Porygon could be upgraded to a Porygon2 just by transferring both at the same time. The project worked, and Porygon2 was tested to see if it had been upgraded to successfully explore space, but it lacked the power to get past the Earth's atmosphere. In addition, because Silph Co. alone developed it, a few unprogrammed actions have been reported, but this could also mean Porygon2 has the ability to learn.
Other than the crystalline body that encases all, Porygon2 is made up of nine parts, or systems of parts. The first of these parts is the complex master drive it possesses, which consists of a cube made of computer chips on the outside, while the inside contains hidden disk space with components and mechanisms used to completely control the being of Porygon2, while also taking and processing information of itself and the surrounding area, in relation to the area within three miles. The second part, the eye, is a mechanism with a screen serving as one hemisphere of the entire sphere. The eyes scan the area and send permanent information to the master drive. This also means the eyes take a high quality picture of the area, which caused the space industry to favor this Pokemon. The third part of this Pokemon is the microphone and speaker that is located at the bill. This microphone takes in a very high-quality recording of all that can be heard, and this information is sent to the master drive permanently, to be processed and analyzed for future and current reference. The speaker was made to make only a few types of frequencies, but these frequencies could be altered to make many different types of output frequencies. The fourth part is an attack-generating device, which the fifth part is too. It takes both parts, though, to successfully create an attack. The fifth part, the second attack generator, has two generators attached in order to give enough power to help make an attack to its full potential. The sixth part is a motor that turns the two limbs at the sides of the body, whereas inside these limbs are generators that create the magnetic force that allows Porygon2 to stay aloft. The seventh part is the main power generator, which is a magnetic-force generator. It has several magnets inside that rotate other magnets and metals, creating electricity. It stops every ten years, but to start it again, one only needs to have Porygon2 put back into cyberspace, and the magnets start their cycle again. The main power generator delivers power to all components, though some need more power, so additional generators were made. The eighth part is a fan, which keeps the unit at a constant temperature. The ninth part is another network hard drive, where Internet access is reached, and attack information is kept and processed.
