Fluffy is an ability that provides dual effects to the Pokémon that possess it. Introduced in Generation VII, this ability halves the damage taken from moves that make direct contact but comes with a notable drawback: the Pokémon with Fluffy takes double damage from Fire-type moves.
Damage Reduction: Fluffy effectively reduces the damage taken from any contact moves by 50%. For instance, if a Pokémon with Fluffy is hit by a move like Tackle or Close Combat, these moves will deal only half the usual damage. This makes Fluffy particularly useful defensively, especially against physical attackers relying on contact moves.
Fire Weakness: The trade-off for this defensive boost is an increased susceptibility to Fire-type moves. Specifically, a Pokémon with Fluffy will take double the damage from any Fire-type attack. This is an important strategic consideration, as it makes Fire-type Pokémon and moves significant threats to those with the Fluffy ability.
