Bring them to the battle institute (brings them up to level 50) and look at the its stats that way, then plug those stats in an IV calculator --- "You got to be careful if you don't know where you're going, because you might not get there." - Yogi Berra
Battle Institute. Auto-levels to 50, use those stats in a IV calculator, gets within an odd/even IV rate (if 6IV, all will be the same as one that has all 6 at 30, and 28=29, 26=27, etc.). --- 3DS FC: 1590-4884-9269 | PKMN X - IGN: Sapphire (Shiny Charm obtained: 2/5/2014) Friend Safari: Fire - Growlithe, Charmeleon, Braixen | TSV: 401
Depends on what you want. Exact number of general 31/0 IVs?
If you want an exact number, the Battle Institute is your best friend.
If you want to know if it's simply 31 or 0, the Ace Trainer in Kiloude City is your best friend. --- PSN: Xzotic123; 3DS FC: 4270-1839-6523 Pokemon Y (Serif) - Electric: Electrode, Pikachu, Zebstrika TFC Member, OGPC ID #00043
