Ability

Pokémon in the Generation III games were given abilities (Japanese: 特性 special characteristic), amongst other new concepts. Abilities serve to give Pokémon a trait that would assist them in battle such as Rough Skin on Sharpedo which allows the foe to take damage on direct contact.

All Abilities from Generation III remain in Generation IV, except for Cacophony that was removed and Air Lock was moved from #77 to #76.

Interestingly enough, abilities are very similar to Pokémon Powers from the Trading Card Game.

Each Ability listed above is linked to an article containing a list of Pokémon that learn that ability. For those lists:

Pokémon listed under 'Single ability' can only have that ability, for example, Squirtle can only have Torrent. (233 Pokémon)
Pokémon listed under 'Dual ability' can have that ability or another, for example, Chansey can have either the ability Natural Cure or the ability Serene Grace. (260 Pokémon)

Individual Pokémon can only have one ability - Pokémon that are under a dual ability listing have a 50-50 chance of having either of their two abilities when encountered or hatched by a trainer.
