Flavor/Design: Porygon now has an Metallic armor covering it and its color scheme looks similar to Magnemite's. Alolan Porygon are a huge mistery for even scientists to understand, they suddenly started showing up in Alola, though, many people suspect that actually, they are coming from the Aether Paradise, through holes in the time-space rift.
Pokemon: Porygon 2

Flavor/Design: Porygon 2 now has an Metallic armor covering it and its color scheme looks similar to Magneton’s. Porygon 2 were brought from Johto to Alola by jets, a rumor says that one of these jets exploded, and only one Poryon 2 survived, but it had the Steel parts of the plane and gathered the electricity from the motor, the Pokémon found a Ditto in Alola and they started to generate many Alolan Porygons.

Flavor/Design: Porygon-Z now has an Metallic armor covering it and its color scheme looks similar to Magnezone's. Porygon-Zs living in Alola had a tough time adapting to the ambient, Scientists found those pokémon and made their laborories home for porygon, eventually, they became influenced by the strong magnetism and multiple experiments and ended up turning into Alolan Porygon-Z.
I'm not sure if the Slate has ended or not, but I just wanted to share this idea with y'all :)
