Magma Armor (ability)

Magma Armor is an Ability introduced in Generation III. It is exclusive to Fire-type Pokémon.

In battle
Magma Armor prevents the Pokémon from becoming frozen; for example, from moves like Ice Beam, Powder Snow and Blizzard.

Outside of battle
If a Pokémon with Magma Armor up front and at least one Pokémon Egg are among the party Pokémon, the number of steps required to hatch the egg are halved. This effect also applies with Flame Body.
