Stunky

Skunk Pokémon ^#434

From its rear, it sprays a foul-smelling liquid at opponents. It aims for their faces, and it can hit them from over 16 feet away.

If it lifts its tail and points its rear at you, beware. It’s about to spray you with a fluid stinky enough to make you faint.

- Stench
  This Pokémon's damaging moves have a 10% chance to make the target flinch with each hit if they do not already cause flinching as a secondary effect. This ability does not stack with a held item. Overworld: The wild encounter rate is halved while this Pokémon is first in the party.
- Aftermath
  When this Pokémon is knocked out by a move that makes contact, the move's user takes 1/4 its maximum HP in damage.

- Keen-Eye
  This Pokémon cannot have its accuracy lowered. This ability does not prevent any accuracy losses other than stat modifiers, such as the accuracy cut from fog; nor does it prevent other Pokémon's evasion from making this Pokémon's moves less accurate. This Pokémon can still be passed negative accuracy modifiers through heart swap. Overworld: If the first Pokémon in the party has this ability, any random encounter with a Pokémon five or more levels lower than it has a 50% chance of being skipped.

It protects itself by spraying a noxious fluid from its
rear. The stench lingers for 24 hours.
