Legit or Not?

[DmitritheDitto]

So I got a Mew today from my cousin...he said he had tons of them and he doesn't know what to do with them so he gave me one...I'll like to know if it's legit or not?

From what I'm seeing it could be the 20th annverisary mew but can anyone tell me if it's legit or not?

Looks hacked to me, its ID doesn't match what the event's Mew should be.

Remember that there is a hack-checking thread in the Trade Corner section so make sure you consult that thread next time you think you have a suspicious hacked Pokemon.

Please next time send them over [The official hack-checking thread], or report the post so it gets moved. It's there for a reason :/
