Prevents other Pokémon's moves or Abilities from lowering the Pokémon's stats.

The Pokémon makes it rain when it enters a battle.

The Pokémon's marvelous scales boost the Defense stat if it has a status condition.

Turns the ground into Misty Terrain when the Pokémon enters a battle.

Natural Cure heals any status conditions upon switching out or completing a battle (if it was in battle at the end of the battle).

This effect will occur if Natural Cure is the Pokémon's Ability in battle when it switches out and is not suppressed; a Pokémon that obtained the Ability with Trace will have its status condition cured when it switches out, whereas a Pokémon which has Natural Cure but has been affected by Gastro Acid will not.

Powers up moves that are super effective.

All moves used by or against a Pokémon with this Ability cannot miss. It also allows Pokémon to be hit during the semi-invulnerable turn of Fly, Bounce, Dive, Dig, Shadow Force, Sky Drop, and Phantom Force. If a K.O.-Move is used by or against the Pokémon it will also hit.
The only attacks, that are affected by this Ability in multibattles, are likewise either used by or against the Pokémon.

Outside of battle
Outside of battle, if a Pokémon with No Guard is in the first place in the party (even if fainted), the wild Pokémon encounter rate increases by 50%.

Normalize makes all moves (including status moves) used by the Pokémon with this Ability act as though they were -type instead of their usual type.

If Normalize makes Thunder Wave a -type move, it can affect -type Pokémon but not -type Pokémon, unless the Pokémon is affected by Foresight or Odor Sleuth.
If the move Freeze-Dry is affected by Normalize, its ability to hit -type Pokémon super effectively is retained.

If Electrify is used on a Pokémon with Normalize, all its moves turn to the type rather than type.

-type moves used by the Pokémon with this Ability will receive a 20% power boost.

When this Pokemon has 1/3 or less of its maximum HP, rounded down, its attacking stat is multiplied by 1.5 while using a -type attack.

The Pokémon passes its item to an ally that has used up an item.
