How to determine if a Pokemon is Legit

[KermitYoung]

Look folks, I have a simple question. I need to know if there is a surefire way to determine if a pokemon that you own is legitimate. I have four pokemon that I need to find out if they are legitimate.

Also, please don't mention the normal methods. I know that a low-level pokemon caught in a masterball/cherishball in an odd location is obviously fake. Thing is, my four pokes all appear normal, but they were received from the GTS and I really wish to find out if they are legit.

Any help you could give would be sincerely appreciated.

there is a simple question and simple answer thread for a reason. this could easily go in there.

check the IV's and EV's to see if theres anything suspicious.
check the location.

This. Although the matches need to be on random Wi-Fi, not Friend battles.

The servers of PBR can sometimes detect things like wrong hexadecimal hidden numbers (Johto balls, shiny leaves, Platinum and HGSS hatched and new locations, Legendary Pokémon locations, etc.), missing region and/or version of origin (Hoenn-Ruby, Distand Land, etc.), incongruent data ("ALAMOS" Darkrai with Classic Ribbon and in a Cherish Ball but lacking the Fateful Encounter flag), non-matching between the Personality Value and the ability binary number (Poison Heal Breloom with a number of 0 as its ability value) and some other things. Moreover, when you're copying the storage system from your version to PBR, the game will also check automatically if there are Pokémon with more than 510 EVs or if Mew/Deoxys doesn't have the Fateful Encounter flag, rendering them as Bad Eggs in the process.

The GTS alone is a bad and inaccurate way to check for hacks; unfortunately there are quite a good number of hacked Pokémon going around on its servers.

The GTS in general is garbage. It's too bogged down with people offering Lv.2 Bidoof in exchange for Lv.100 Mew or Rayquaza.

EDIT: On topic, a good way I've heard of is to use Pokesav. I've never used it myself, but from what I hear, you can check all of the hidden values for your Pokemon, which would be a good way to make sure there's nothing fishy.

Yeah, it's also another way of creating hacked Pokemon, via ROM save.
