7. Porygon, Porygon2 and Porygon-Z
Again, this may be one entry that’s slightly unexpected, but just think for a moment: Porygon was an artificially created Pokémon, probably manufactured by Team Rocket scientists during their control of Silph Co., so its purpose is most likely one of criminal intent given its ability to travel freely through cyberspace. Perhaps some Stock Exchange fixing, or a phishing scam? Thankfully, Team Rocket’s control of Silph Co. was relinquished, and the Silph bigwigs decided that Porygon had the potential for space exploration.
With the Up-Grade item, Porygon evolves into Porygon2 and is perfectly equipped for space travel. Strangely though, it began behaving in a way that was not programmed. As the Dex entry for Black and White tells us, it didn’t meet the standards to actually be used, probably due to the artificial intelligence it had developed. Who knows what would have happened if it had been sent to the moon, and decided it’d rather do something else?
Lastly, in its final form, Porygon-Z was an attempt to iron out the kinks that had plagued Porygon2. The trade item necessary to trigger the evolution, however– the Dubious Disc– should have been a huge clue that something might go wrong. Where did this disc come from? Who created it? Did they intend it to be used on Porygon and its evolutions? Either way, something went horribly wrong. Not only did it not fix the bugs in Porygon2, but it also gained the ability to visit “alien dimensions”. When you consider the fact this item is found in Team Galactic’s HQ (yeah, the organisation that wanted to control time, space and dimensions) it becomes clear that this upgrade to Porygon2 was probably intended to communicate with Giratina in the Distortion World. Luckily, it didn’t appear to work, as, to quote HeartGold and SoulSilver‘s Pokédex, it “seems there might have been an error…”. That said, its behaviour is still weird, and we don’t know exactly what happened to it. Apparently, it sometimes shakes uncontrollably for no reason then stops suddenly, which may or may not be Post-Traumatic Stress Disorder, but it could just as easily be it shifting between dimensions. Who knows what horrors poor Porygon-Z has seen or is planning to perpetrate.
