Stunky

Diamond +2: It protects itself by spraying a noxious fluid from its rear. The stench lingers for 24 hours.

Pearl: It sprays a nose-curling, stinky fluid from its rear to repel attackers.

Platinum +6: It sprays a foul fluid from its rear. Its stench spreads over a mile radius, driving Pokémon away.

HeartGold / SoulSilver: The foul fluid from its rear is so revolting that it can make people feel queasy up to a mile and a quarter away.

Sword: 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.

Shield: 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.

Legends: Arceus: The poison that gushes from its aft end is accompanied by an utterly evil-smelling odor with such potency that one whiff can induce memory loss.
