What affects a pokemons stats?

Answer 1

Pokemon's stats are pretty simple. Attack, Defense, Special Attack, Special Defense, and Speed. And HP ( health points) Attacks form other Pokemon are usually the cause of stat loss. For example, A move like Growl will lower the attack for the remainder of the fight. Scary Face lowers speed. Leer lowers defense etc.... Alternatively, there are also attacks that UR Pokemon can use that raise their stats. For example, Calm mind will RAISE the special attack stat. Dragon Dance will raise both Attack AND speed...etc....
