Meh, TPC has been stealing ideas from other places for ages now, going as far back as Gen 4 where some of the evolutions of Gen 1/2 Pokemon added started from Gen 3 ROMhacks (eg: Mismagius, Tangrowth, etc.), not all, but some, then Gen 5's merging legendaries came from a Gen 4 ROMhack, Gen 6's Mega came straight from Digimon, Gen 7's Z-crystals too, etc....
