Only if their origin is Sword or Shield. (the markings, whether is it GB or Pentagon or Clover or GO, is based on origin game)

Perfect. Thanks!

yeah trade over locally from hacked switch to unhacked switch.

Melmetal isn't available in any games until LGPE. Your PK8 probably has bad data, so if you can, please share it like the above post says. I'm unable to replicate this with any Melmetal (transferred from LGPE legitimately or hacked into SWSH).

You can convert your past-gen Pokémon to PK8s in PKHeX temporarily to view the Shiny Xor. Hover over the Pokémon's PID to see it (0 is Squares, 1-15 are Stars). It will also show the type of sparkles in the top-left corner (yellow Square or red Star). PKHeX doesn't currently show the Shiny Xor on hover outside of Gen 8 save files. If a Pokémon is Shiny and was met in a Fateful Encounter, its Shiny sparkles will always be Squares regardless of PID, so most Event Pokémon will be Squares instead of Stars.

For sake of anyone reading this in the future. If you have a WC4 and need the PCD for injection then drop the WC4 in PKHex (using a gen 4 save) then export as PCD.
