How do I know what IVs my Pokemon has?
This value is hidden, and you can’t tell a Pokemon’s IVs just by looking at their stats. There are a few ways you can determine your Pokemon’s IVs:
1. A very complex formula explained here:
http://www.serebii.net/games/ivs.shtml
2. A much easier to deal with IV calculator:
http://www.serebii.net/games/iv-calc.shtml
Since IV calculators are only COMPLETELY accurate when your Pokemon is at LV 100, the calculator will show the min, max, and average IVs your Pokemon can have. For example, if it shows 20 for the minimum and 25 for the maximum, your Pokemon has an IV of anywhere from 20 to 25. The average will just be the number in between those two numbers, in this case 23. The average is NOT necessarily your Pokemon’s exact IV.
You will get more accurate answers if your Pokemon is at a higher level. Also remember that if you have battled with your Pokemon then you have gained EVs (explained below), which will make the stats inputted in the IV calculator inaccurate. If your Pokemon was not at a high level when you caught it, use Rare Candies until it is as high as you can get it, preferably LV 20 at least. Then you can input the data and reset to save the Rare Candies.
3. In Emerald only, you can check with the “Pokemon Breeder” at the Battle Frontier. If you’re not looking for specific numbers, just the general range of your Pokemon’s IVs, he is your best bet. He is located in the house directly above the Pokemon Center at the BF.
He will rate the first Pokemon in your party, first by TOTAL IV count:
“This one, overall, I would describe as being of average ability.” 0 – 90 total IVs
“This one, overall, I would describe as having better-than-average ability.” 91 – 120 total IVs
“This one, overall, I would say is quite impressive in ability!” 121 – 150 total IVs
“This one, overall, I would say is wonderfully outstanding in ability!” 151 – 186 total IVs
And then he will rate your Pokemon’s highest INVIDIUAL IV count (note that if your Pokemon has more than 1 perfect stat, he will choose one at random to mention):
“Incidentally, the best aspect of it, I would say, is its (insert stat here)..."
“That stat is relatively good. ...Hmm... That's how I call it.” 0 - 15
“That stat is quite impressive. ...Hmm... That's how I call it.” 16 - 25
“That stat is outstanding! ...Hmm... That's how I call it.” 26 - 30
“It's flawless! A thing of perfection! ...Hmm... That's how I call it.” 31
