Why does my PP go down two instead of one?

Question

I just noticed this, that after I beat the champian my Pokemon's PP started to go down two instead of one, and I don't know why.

What were you fighting?

Answer 1

Because your opponent has the ability Pressure, or you're just mistaken. Beating the Champion should not affect your PP at all. It is extremely unlikely for this to be a glitch, unless you're playing a hacked version that tends to be bit buggy.

Answer 2

The reason you are losing PP usage is because your opponent has the ability pressure. Pressure raises the Pokemon's PP usage. With this said, it's not going to increase your maximum PP, it's going to decrease the amount of times you use a move. Fortunately, this only works sometimes - not always.

For example, I was versing a legendary (with pressure) with my camerupt having the move eruption. Every time I used the move, I would lose 2 PP rather than 1 PP.

Hopefully this Helped!
