>>43163344Wouldn't feel right, since that's what their nature/characteristic is for. For me, those two traits are what determines their personalities, despite the pokedex or anime or something suggesting they act a certain way.
For example, you can have a Docile/Timid/Calm Beedril, despite the anime portraying most of them as having a short-temper. Hell, I can see an "Impetuous and silly" Mewtwo despite it being serious in most media.
