Whelp, requesting hack check again. Got this one from Wonder Trade.
Pretty sure this came from HGSS via Celadon Game Corner (and yes can be bred with Ditto, I believe), but I'm more suspicious of the OT because of the font/text.
Pokémon Species: Porygon-Z

Any other notes?: The Pokémon is tagged as Japanese, but the OT is not in blocky text. (For example, PC as opposed to ＰＣ.)
