Do you have to ev train a Pokemon in a stat it already has perfect iv's in?

Question

I Iv bred six Pokemon and I wandered do I have to ev train it in those stats

Answer 1

Yes, you do if you want those stats to be the highest they can be. EVs and IVs work seperately. A Pokemon can have a maximum of 31 IVs in each stat, which increases it by 31, and it can have a maximum of 252 EVs in each stat, which increases it by 63 (every 4 EVs increases it by 1.)

Also, a Pokemon can only have 510 EVs overall, spread out in whatever way you want over its 6 stats, without any stat having more than 252. But they can have as many IVs as you want overall, without any stat having more than 31.

Oh yeah, the IVs information only applies to level 100 pokemon.

Darn. I was ninja'd. And your answer is better.

Answer 2

IVs can raise a stat of a level 100 Pokemon by up to 31. EVs can raise the same stat by 63 more. Yes, EV training will make a significant difference.
