From Bulbapedia, the community-driven Pokémon encyclopedia.
Klutz (Japanese: ぶきよう Clumsy) is an Ability introduced in Generation IV. Prior to Generation V, it was the signature Ability of Buneary and Lopunny.
Klutz prevents the effects of the held item of the Pokémon with this Ability from applying.
Klutz does not negate item effects that affect prize money, experience, effort values, or friendship, such as those of the Amulet Coin, Lucky Egg, Power Weight, or Soothe Bell.
The Speed drop from the Macho Brace, and Power items (such as the Power Bracer) is not negated by Klutz.
The Speed drop from the Iron Ball is not negated, but the grounding effect is.
Klutz prevents the Pokémon with this Ability from using Natural Gift; however, it does not prevent the Pokémon from using Fling. If a Pokémon with Klutz uses Bug Bite or Pluck, it will consume the target's held Berry without gaining its effects. If a Pokémon with Klutz uses Judgment, it will be a Normal-type move.
Generation V onward
Klutz now prevents the Pokémon with this Ability from using Fling. If a Pokémon with Klutz uses Bug Bite or Pluck, it will now receive the effects of a consumed held Berry. If a Pokémon with Klutz uses Techno Blast, it will be a Normal-type move.
All effects of the Iron Ball are now negated by Klutz. However, Klutz still does not negate the Speed drop from the Macho Brace and Power items.
If a Pokémon is already locked into a move due to a held Choice item (Choice Scarf, Choice Specs, Choice Band), if the held Choice item is removed while its effect is negated, the Pokémon will be affected by the Choice item lock glitch.
Klutz cannot prevent the form-changing effects of items, but will still negate the other effects of those items (e.g. if a Giratina holding a Griseous Orb has Klutz, it will remain in its Origin Forme, but will not receive the 20% boost in the power of Dragon- and Ghost-type moves). Klutz does not prevent Pokémon with this Ability from Mega Evolving with a Mega Stone or undergoing Primal Reversion with the Red Orb or Blue Orb. Klutz does not prevent Pokémon with this Ability from using a Z-Move with a Z-Crystal.
If a Pokémon with Klutz uses Multi-Attack, it will be a Normal-type move.
Outside of battle
Klutz has no effect outside of battle. Items such as the Everstone, Cleanse Tag, Scarves, and Soothe Bell are not affected.
