Personality effect ?

Question

Let's say I have a pokemon with a modest nature, which lowers attack, but It also has a "proud of its power" personality too. What happens (it's a attack personality)

Answer 1

Those personalities have no effect on your pokemon's stats. While the nature does have an effect, the personalities are just an indicator of your pokemon's highest IV stat. So in the case of yours, it has "Proud of its Power," meaning that its highest IV is in its attack power.

Answer 2

Dt Is Sorta Correct.I Would Like To Add though that IVs, Though They Don't Raise Stats, with lower IVs, they will have lower Stats.
