We try to keep the names as original as possible, kinda, and we're not copying ygo.
SPOILER:
All new porygons (and porygon-Z, wow, surprise) learn a move only they can learn at a specific level, sometimes those are TM/HM moves and you can teach it to them anyways, but if they're not, it's a once-in-a-lifetime chance to get a porygon-evo with an attack it would never be able to learn otherwise. Since Porygon 3.2 is my spoiler porygon, I'll explain some stuff about it: (also, please note that not all new porygons look as awesome and original as 3.2)
Specie: Online Pokémon
Bacon-dex: This Pokémon is used to surf the web, ironically and unrelated to this, it is shaped after a rubber ducky.
Its special move is Surf, this is a HM move, so you can just evolve your pory evo into 3.2 to then evolve it back into the one you wanted just for surf. But imagine 8 porygons (pory 1 & 2 excluded) all with a special move, you can have a really weird porygon-Z that way and stuff.
Porygon-Z got a special move, it should be pretty obvious if you have ever read Porygon2's pokédex and if you look at what Porygon-Z is based upon.
