Natures

Natures can be viewed at the Summary Page of a Pokémon. They determine what berries a Pokémon will like or dislike and it affects the value of two of a Pokemon's stats. The natures are randomly generated when Eggs are hatched, with a 1/25 chance of each one. A Pokemon's nature can be influenced when Nature Breeding.

	-Sour	-Spicy	-Dry	-Sweet	-Bitter
+Sour	Docile	Bold	Impish	Relaxed	Lax
+Spicy	Lonely	Hardy	Adamant	Brave	Naughty
+Dry	Mild	Modest	Bashful	Quiet	Rash
+Sweet	Hasty	Timid	Jolly	Serious	Naïve
+Bitter	Gentle	Calm	Careful	Sassy	Quirky

Feeding a Pokémon a berry which it likes will grant the most EXP, feeding it one it is neutral to will grant modest EXP, and feeding it one it dislikes will grant the least. Pokémon with the natures Hardy, Docile, Serious, Bashful, or Quirky can be fed any berry and remain neutral with it. However, these Pokémon tend to receive less EXP overall since they do not have a favourite flavour.

Stats

The flavour of the berry that a Pokémon likes/dislikes are connected to a Pokémon's Battle Stats and will indicate which stat will be boosted and which stat will hindered. For example, a Timid natured Pokémon likes sweet berries and dislikes spicy berries. In this example, this Pokémon's Stats would boost Speed and hinder Attack or another way of seeing this is the Pokémon is fast moving but has a weak punch. Pokemon that both like and dislike the same flavor will have no stat boosts or losses.

Below is a list of which flavour is associated with which Stat.

Sour	Spicy	Dry	Sweet	Bitter	Any
