>>31004218I think every nature except Gentle, Lax and the neutral ones have some sort of use on some pokemon
>jolly, adamant, timid, modest, bold, impish, careful, calmobvious uses
>hasty, naivefast mixed attackers
>brave, quiet, sassy, relaxedTrick room, walls that don't use their speed but do use both attack stats (e.g. EQ+scald quagsire)
>rash, lonely, naughty, mildUncommonly used, but extremely fast mixed attackers can use these (mixed LO kingdra and rock polish Mega Diancie run rash)
Mild and Lonely might have a use but I can't think of anything that uses it. Taking priority hits is better for fast things. Something that's very fast but already has good defense stats might want to run lonely. Like if Mega Mence's only way to boost speed was agility or some shit, I could see Lonely being the preferred nature on it.
I legitimately can't think of a single, even theoretical pokemon that would want to use Gentle or Lax though. It'd have to be a wall that uses both attack stats and needs to outspeed things and maximize its damage on both sides, but like that's retarded.
