This Pokemon's moves that match one of its types have a same-type attack bonus (STAB) of 2 instead of 1.5, which corresponds to a 33% bonus on all STAB attacks.

This Pokemon's -type moves become -type moves and have their power multiplied by 1.2. This effect comes after other effects that change a move's type, but before Ion Deluge and Electrify's effects.

If this Pokemon is knocked out with a contact move, that move's user loses 1/4 of its maximum HP, rounded down. If any active Pokemon has the Damp Ability, this effect is prevented.

When a Pokémon with Air Lock is in battle, all effects of weather are negated (though the weather itself does not disappear).

During extremely harsh sunlight, heavy rain, and a mysterious air current, even if a Pokémon is negating the effects of weather with Air Lock, the moves Sunny Day, Rain Dance, Sandstorm, and Hail will still fail if used, and the Abilities Drought, Drizzle, Sand Stream, and Snow Warning will still fail to activate. However, all other effects of these weather conditions are negated by Air Lock. If Castform or Cherrim is on the field, it transforms back to its normal form.

The power of this Pokemon's move is multiplied by 1.3 if it is the last to move in a turn. Does not affect Doom Desire and Future Sight. Unlike Payback, Analysis strenghtens the attack even if the opponent´s Pokemon is changed and acts primarily.

When a Pokémon with this Ability is hit by a critical hit, Anger Point maximizes its Attack stat by raising it to +6 stages (regardless of its current stage). This does not apply if the opponent is protected by Substitute.

On switch-in, this Pokemon is alerted if any opposing Pokemon has an attack that is super effective on this Pokemon, or an OHKO move. Counter, Metal Burst, and Mirror Coat count as attacking moves of their respective types, while Hidden Power, Judgment, Natural Gift, Techno Blast, and Weather Ball are considered -type moves.

Arena Trap prevents enemy Pokémon that touch the ground from being exchanged or escaping from battles, including Teleport. Excluded from this are Pokémon.

However, a Pokémon can be exchanged by using Volt switch, U-Turn, Baton Pass or Parting shot or by wearing the item Shed Shell.

This Pokemon and its allies cannot be affected by Attract, Disable, Encore, Heal Block, Taunt and Torment in multibattles. The owner of the ability is protected in single fights. Pokémon that are already under effect of the attacks are not freed from it by scent cover.

While this Pokemon is active, the effects of the Dark Aura and Fairy Aura Abilities are reversed, instead of a 33% increase, - or -type attacks are weakened by 33%.

Causes adjacent opposing Pokemon to lose 1/8 of their maximum HP, rounded down, at the end of each turn if they are asleep.

This Pokemon's allies have the power of their special attacks multiplied by 1.3.

The opponent cannot land a critical hit against Pokémon with this ability. This also applies to the attacks Frost breath and Storm throw, which normally always cause a crititcal hit. Pokémon with the ability Mold breaker, Turboblaze or Teravolt can still land a critical hit.

If this Pokemon is a Greninja, it transforms into Ash-Greninja after knocking out a Pokemon. As Ash-Greninja, its Water Shuriken has 20 base power and always hits 3 times.

When a Pokémon with Beast Boost directly causes another Pokémon (including allies) to faint by using a damaging move, its highest stat (other than HP) is increased by one stage. If this stat is already at +6 stages, Beast Boost will not activate (not even in the case of a tie of two or more stats).

For determining the highest stat, Beast Boost does not take into account stat stages, held items, or reductions due to status conditions; however, it does consider the effects of Power Split, Guard Split, Power Trick, Wonder Room, and Speed Swap. In the case of a tie between multiple stats, it increases one stat, prioritized in this order: Attack, Defense, Special Attack, Special Defense, and Speed.

If the Pokémon fainting ends the battle, Beast Boost will not activate. Beast Boost activates after the Pokémon gains Attack from Fell Stinger. If a Pokémon with Beast Boost defeats a Pokémon with Mummy using a contact move, the Pokémon's Ability will become Mummy before Beast Boost has the opportunity to activate.

Increases special attack by one level when the Pokémon´s KP drops below half due to a direct attack. Berserk will not activate if the KP drops below 50% due to effect damage, such weather, status conditions, Leech seed, Items, etc.,Berserk can activated any number of times as long as the user is healed back above 50% of their maximum KP. This effect applies after all hits from a multi-hit move. Sheer Force prevents it from activating if the move has a secondary effect.

The Pokémon´s defense cannot be lowered by enemy attacks, however Guard swap, Heart swap and Guard split still have an effect. Self-inflicted decreases in defense are also not prevented.

Big Pecks can be overriden through Teravolt and Turboblaze.

If a Pokémon with Blaze has only ⅓ or less of its maximum KP, its attack or special attack increases by 50% when using a Fire attack, depending on the damage class. For attacks of other types, the offensive value remains at the original value, also when the Pokémon regenerates its KP back above the critical value.

Pokémon with Bulletproof are not affected by ball and bomb moves, as well as some cannon-based and blast-based attacks.

The Ability affects the following moves:
Aura Sphere, Zap Cannon, Egg Bomb, Electro Ball, Energy Ball, Rock Wrecker, Rock Blast, Searing Shot, Focus Blast, Ice Ball, Gyro Ball, Bullet Seed, Magnetbombe, Sludge Bomb, Weather Ball, Mist Ball, Octazooka, Acid Spray, Seed Bomb, Mud Bomb, Beak Blast, Shadow Ball, Barrage, Origin Pulse.

If the Pokémon eats a Berry, it restores 1/3 of its maximum KP in addition to the effect of the Berry. This is also the case if it eats an opponent´s Berry by Fling, Bug Bite or Pluck but only if it also benefit from the Berry´s original effect. So it only heals itself when it is poisoned and eats the opponent´s Pecha Berry. Cheek Pouch will not activate if the berry is uses elsewhere, such as by Natural Gift.
