Illusion will change the appearance of the Pokémon to that of the last Pokémon in the player's party. Illusion will not disguise the Pokémon if the last Pokémon in the player's party is fainted or is of the same species. Illusion will replicate the type of Poké Ball, nickname (or species name if none), Shininess (if any), gender, and form of the Pokémon it is masquerading as; however, it does not replicate the level of the masqueraded Pokémon. If an Egg is in the last position, the Pokémon that is in the Egg will be shown. The effect is only aesthetic: effects like the move Attract still use the Pokémon's actual gender.
The illusion wears off when the Pokémon with this Ability is directly damaged by a damaging move or when Illusion is negated or replaced, causing the Pokémon with this Ability to appear as its true self. Indirect damage or loss of HP (such as through Substitute, Life Orb, weather, status conditions, entry hazards, recoil, and so on) will not break Illusion. If the Pokémon with Illusion is hit by a multi-strike move, the illusion will be broken after the first hit.
A Pokémon with Illusion can disguise itself as another Pokémon with Illusion, provided that they are different species.
Role Play fails if the target has the Ability Illusion. Skill Swap fails if either Pokémon has Illusion. Illusion cannot be copied by Trace. If a Pokémon obtains this Ability with Imposter or Transform, it will not disguise itself.
In Pokémon Black and White, if the player visits Lostlorn Forest with a GameStop Entei, Raikou, and/or Suicune in their party, they can encounter a Zoroark, which enters the battle already disguised as the Legendary beast that has a type advantage over the beast closest to the first slot in the player's party (Entei in case of Raikou).
Illusion can now disguise itself as another Pokémon with Illusion of the same species.
Illusion now disguises the Pokémon as the last conscious Pokémon in the party.
On the user interface, an opponent's Pokémon disguised by Illusion will appear to be the same type as the species it is disguised as (even if it is affected by a move such as Soak).
If a Pokémon with Illusion uses a Z-Move, the illusion wears off immediately before using the Z-Move.
If a Pokémon with Illusion successfully calls for help in an SOS Battle, it will disguise itself as the summoned ally.
Outside of battle
Illusion has no effect outside of battle.

In other games
In Pokémon Mystery Dungeon: Gates to Infinity, the Ability functions similar to the main series games for foe Pokémon. A Pokémon with this Ability can transform into another Pokémon that can be found on the same floor of a Mystery Dungeon. For partner Pokémon, this Ability becomes nonexistent.
In Pokémon Super Mystery Dungeon, leader or ally Pokémon with this Ability transform into Kecleon. An enemy Pokémon with this Ability disguises as another enemy Pokémon that can be found on the same floor. As long as the illusion stays up, the Pokémon receives a 40% increase in the power of its moves.
The illusion wears off when the Pokémon with this Ability is directly damaged by a damaging move or when Illusion is negated or replaced, causing the Pokémon with this Ability to appear as its true self. Indirect damage or loss of HP (such as through Substitute, weather, status conditions, traps and so on) will not break Illusion.

|Zoroark||Zoroark's eyes glow light blue and its outlines start to glow pink. Then, a magenta wave of energy appears by its face and moves down to its feet. As the wave moves down, its body changes its shape into the opponent, or Zoroark causes the opponent to see illusions of its choosing (sometimes with its eyes glowing red), or Zoroark glows purple and it transforms into another Pokémon.|

- In Generation V, if Entrainment is used on a Pokémon with Illusion while it is disguised as another Pokémon, when its Ability activates the banner will state that the Ability belongs to the Pokémon that was used as the disguise. If the Pokémon's Ability is changed again, these messages will correctly state the Pokémon who the Ability belongs to when it activates.
- Although this Ability is forbidden in Pokéstar Studios, Brycen uses a Zoroark with this Ability in one of the Brycen-Man movies.
