A Nature will add two to a Base Stat and subtract two to another Base Stat, making a completely different Base Relation in many cases. Now you can focus more on this Charmander’s ATK without even worrying about increasing its SPEED.
Look at this Brave Charmander, now at level 20.
Base Added Total
HP - 4 + 0 = 4
ATK - 7 + 10 = 17
DEF - 4 + 0 = 4
SPATK - 6 + 5 = 11
SPDEF - 5 + 0 = 5
SPEED - 5 + 5 =10
This Charmander can now potentially be a sweeper with its superior ATK and SP.ATK, plus with some SPEED it gains evasion bonuses. Though, due to its lower other stats, if this Charmander fails to defeat an opponent it is likely to be swept itself.
Like Natures, Vitamins can alter Base Stats. Vitamins are expensive items that can be fed to a Pokemon, with any combination of 5 vitamins at max, improving a Pokemon’s Base Stats in order to allow them to change how they distribute stats as they level up.
Here’s a chart of Natures and how they effect your Pokemon’s Base Stats. Natures also effects what kinds of food your Pokemon like.
