During harsh sunlight, Leaf Guard prevents the Pokémon from being afflicted by non-volatile status conditions and Yawn (including via the Flame Orb and Toxic-Orb). It has no effect on any current status condition prior to the weather being set up.

If a Pokémon with this Ability is drowsy due to Yawn, if there is harsh sunlight when it would fall asleep, the Ability activates and keeps it awake.

By floating in the air, the Pokémon receives full immunity to all Ground-type moves.

The user's weight is halved. This may decrease the damage taken from Low Kick and Grass Knot, increase the damage taken from Heavy Slam and Heat Crash, and lower the base power of the user's Heavy Slam and Heat Crash.

This Pokemon is immune to -type moves and raises its Special Attack by 1 stage when hit by an -type move. If this Pokemon is not the target of a single-target -type move used by another Pokemon, this Pokemon redirects that move to itself if it is within the range of that move.

Limber prevents the Pokémon from being afflicted by paralysis. A Pokémon with this Ability will be cured of paralysis if it is paralyzed while in battle (such as if it gains the Ability outside of battle or by an effect like Skill Swap, or is paralyzed by a Pokémon with an Ability like Mold Breaker).

Liquid Ooze causes HP-draining moves used on the Pokémon with this Ability to damage their user instead of healing them.

If a Pokémon with Liquid Ooze is hit by a draining move such as Giga Drain or Leech Life (including the status move Strength Sap), or takes damage from the effect of Leech Seed, the amount of HP that would be recovered by the opponent is dealt as damage instead (after applying the effect of Big Root). The damage dealt by the move is not affected.

Even if the user of the HP-draining move cannot heal from its effect due to having full HP or the effect of Heal Block, it will still take damage

The Ability affects the following moves:
Drain Punch, Absorb, Leech Life, Draining Kiss, Leech Seed, Giga Drain, Horn Leech, Strength Sap, Mega Drain, Parabolic Charge, Dream Eater, Oblivion Wing

All sound-based moves become Water-type moves.

The Pokémon uses its moves without making contact with the target.

When a Pokémon with this Ability is hit by a move that makes contact, the Pokémon with this Ability will steal the held item of the attacking Pokémon. It will not activate if the Pokémon with this Ability already has a held item. It will not activate if the Pokémon with this Ability is knocked out by that move.

If a Pokémon with this Ability is hit by a multi-strike move that makes contact (such as Fury Swipes), the item will not be stolen until after the final strike. If multiple Pokémon with this Ability are hit by the same move that made contact, Pickpocket will activate for the fastest one that does not already have an item.

Pickpocket activates after Magician and the Sticky Barb, and after Thief and Covet steal a held item. Consequently, the Pokémon that has Pickpocket will always end up with the item. Pickpocket also activates after Knock Off, Bug Bite, and Pluck, meaning that the stolen item will not be lost, and if it does lose its item due to these moves it can immediately steal another.

At the start of battle or at the end of a turn, if Minior's HP is above half, it will change into its Meteor Form. At the end of the turn, if its HP is below half, it will change back to its Core Form.

While in Meteor Form, Minior cannot be afflicted by status conditions or become drowsy due to Yawn. Rest will fail when used by Minior in Meteor Form. If Core Form Minior is switched in while grounded (due to Iron Ball, Gravity, or being Baton Passed Ingrain), it will be poisoned by Toxic Spikes before Shields Down switches it to Meteor Form.

Role Play, Gastro Acid, Worry Seed, Simple Beam, and Entrainment fail if the target has the Ability Shields Down. Skill Swap fails if either Pokémon has Shields Down. Shields Down cannot be copied by Trace, Power of Alchemy, or Receiver. Shields Down cannot be replaced by Mummy or suppressed by Core Enforcer. If a Pokémon other than Minior obtains Shields Down with Imposter or Transform, the Pokémon will not change forms and will not be immune to status conditions (even if it transformed into Meteor Form Minior).

Mold Breaker, Turboblaze, and Teravolt have no effect on Shields Down. If a Pokémon with Poison Touch uses Sunsteel Strike on a Minior in Meteor Form, it will not be poisoned.

If Minior gets a status condition while in Core Form and later changes into Meteor Form, the status condition remains in effect.

Soundproof prevents all effects from sound-based moves, granting Pokémon with this Ability immunity from them. The Ability affects the following moves:

Parting Shot, Perish Song, Uproar, Roar, Sing, Chatter, Grass Whistle, Growl, Bug Buzz, Noble Roar, Round, Screech, Metal Sound, Clangorous Soulblaze, Disarming Voice, Hyper Voice, Sparkling Aria, Clanging Scales, Snore, Snarl, Supersonic, Boomburst, Relic Song, Confide, Heal Bell, Echoed Voice

When a Pokémon with this Ability is hit by a move that makes contact, the Speed of the attacking Pokémon is decreased by one stage. If a Pokémon with this Ability is hit by a multi-strike move that makes contact (such as Fury Swipes), each hit activates this Ability.
