If I had asked the question I would have BA it. It's really good, thanks for helping.

Answer 2

there are 25 in total
5 are neutral no stats are effected
then 5 increase atk
5 for def and 5 for so but they also decrease a stat
they increase and decrease a stat by 10%
so if i had sassy nature on a bulbasaur it would be plus spdef by 10% - speed by 10%
they also decide what tastes your pokemon like
for more info and actually which nature affects what click here tells you everything bulbapedia

Hey, I just noticed, on the skills the increased stat is red and the decreased stat is blue!

yep it tells you everything

But that does not apply in Generation I. II. or III games.
You had to know what that nature was; and I'm not sure about Diamond/Pearl/Platinum.
