Pokémon Natures
If you've read my EV guide page yet, this page goes hand-and-hand with it. A Pokémon's nature also has an effect on your Pokémon's initial stats. The chart below explains which natures increase and decrease certain stats. Note that this applies to the third and fourth generation Pokémon games (Ruby/Sapphire/Emerald/Fire Red/Leaf Green/Diamond/Pearl/Platinum).
