The software by which Porygon-Z were first created – the so-called "dubious" disc – was a program riddled with errors. The first version of Porygon-Z not only broke down frequently, but their behavior was extremely erratic, and they would sooner attempt to delete the world economy and instigate nuclear war than explore any truly alien dimensions. Part of this could be attributed to simple shoddy programming; Bill may be a legend, but he is also a man who infamously managed to turn himself into a pokemon. But even once his most dangerous bugs were fixed by his more competent colleagues, others were constantly discovered; the Porygon-Z project, or at least its funding from the League, seemed destined for cancellation.

In desperation, the scientists behind the Porygon-Z project decided to release this new pokemon's entire source code to the public, in the hopes that mass enthusiasm for this pokemon's intended mission would inspire people to debug this pokemon. Bug-fixing was done only in bits and pieces, only as much as necessary to make the pokemon perform whatever new task had been dreamed up. Indeed, new bugs were frequently created by the unpredictability of Porygon-Z's artificial intelligence and the errors of neophyte coders, and a couple villains attempted to replicate the brief chaos the original Porygon-Z caused to no avail.

Instead, it was the ability to customize Porygon-Z which inspired the masses, for the ability to play Arceus has tapped mankind's creative energy like nothing since writing was developed from the Unown. Today, anyone with a Porygon-Z and an internet connection can not only use these pokemon to play video games and choose between more skins than all the possible transformations of Ditto, but can also download countless techniques which let them adapt on the fly to nearly any opponent in battles.
