This is a Go Park file (gp1) for a level 1 Melmetal, if you're into that sort of thing. Caught and evolved in Pokemon Go of course. It doesn't have the best IVs.
Screenshots show the Meltan (before evolving) in PoGo and the Melmetal in PoGo before being transferred to Go Park. Calcy IV was used to display level and stats in PoGo.
I have also included a level 1 Meltan .gp1 file with this post this is not the same Meltan that was evolved into this Melmetal, obviously.
