Each Pokemon has a random nature given to it from 25 different Natures. These Natures increase one of the Pokemon’s stats by 10% while decreasing another one by 10%.

There are five natures that increase and decrease the same stat by 10% which in the end has no effect on their overall stats. Typically you want to have a nature that benefits the Pokemon’s main stat and hurts one that it doesn’t use. (For example: Increase ATK while decreasing SP. ATK.)
