If I were to hit a level 31 slaking with a low kick with a level 31 machoke in emerald. How much damage would it do?

Question

Well since I'm using low kick it depends on the weight and I'm currently fighting the fourth gym in the game and the last Pokemon is slaking also I would like a percentage of the hp taken out since I don't know the hp of a level 31 slaking

Comments

This also depends on the EVs, IVs and natures of both Slaking and Machoke, though you wouldn't be able to find all of those.

Answer 1

We actually do know the list of opposing trainers in Emerald. In the gym battle, Norman's Slaking is suffixed with a [250], which means it has IVs of straight 30 and, like every opposing Pokemon outside of the Battle Tower etc., no EVs anywhere.

The maximum possible Attack stat on a level 31 Machoke is 105. Because of badge boosts, having the Stone Badge means this will really count as 115, but even then, you have this:

252+ Atk Machoke Low Kick (100 BP) vs. 0 HP / 0 Def Slaking: 112-132 (78.3 - 92.3%) -- guaranteed 2HKO

...And Slaking has both Sitrus Berry and Counter for when you come up short. Don't bank on that.
