Sometimes when you catch a pokemon you like, it has a bad personality. Like naughty or it hates you... if you spend more time with it and treat it well... will it's personality change? I really want to know the answer.
erm im confused u mean its nature like naughty no thatll never change cause natures boost and lower diffrent stats by 10% like timid raises speed and lowers defence ( i think) wereas modest raises a pokemons special attack and lowers its attack
