If it can learn the move in a previous generation, then it won't show up as being hacked as long as the Pokemon in question originates from that generation.

For example: https://www.pokecheck.org/?p=detail&uid=3483893

My Metagross has four moves it can only learn in Generation 3, but they all show up as valid, since they're possible moves on this particular Metagross.

Awesome! Thanks for the fast reply!

Hi there! First time posting, and I wanted to start off by saying thanks for making this tool! =D

Since Gen 6 announced Mega Ampharos, I'm going to be transferring up my favorite Ampharos all the way back from Gen 3! However, my Ampharos has Reflect on it, which Ampharos wasn't allowed to have starting with Gen 5 due to an Egg Group change. Will this cause my Ampharos to appear on the legality tracker as hacked? (I don't plan on trading my Ampharos but this could pose a problem for someone in a similar situation.)

Thank you!

P.S. Before someone asks why I have to transfer an Ampharos from Gen 3 instead of just catching a new one, let me just say that I have a box and a half full of Ampharoses on my Heart Gold version each with unique nicknames. I'm kind of obsessed. =P
