Electric-type moves do not work on the Pokémon. Instead, they restore 1/4 of its max HP.
Volt Absorb (Japanese: ちくでんElectricity Storage) is an Ability introduced in Generation III.
Effect
In battle
Generation III
When a Pokémon with Volt Absorb is hit by a damaging Electric-typemove, its HP is restored by one quarter of its maximum HP, and the move will have no effect on that Pokémon (if a Pokémon with this Ability already has full HP, the Electric-type move will do nothing).
Volt Absorb will not activate if the Pokémon is protected from the Electric-type move.
Generation IV onward
Volt Absorb will now also activate when a Pokémon with it is hit by an Electric-typestatus move.
Multistrike moves that are turned into Electric-type moves, such as by being affected by Electrify or Galvanize, will only activate this Ability once.
If a Pokémon with Volt Absorb is holding a Cell Battery, Volt Absorb absorbs the move, so the Cell Battery's effect is not triggered.
In Pokémon UNITE, Volt Absorb is Zeraora's Ability. It converts 8% of the damage Zeraora was dealt as Attack, up to 200 Attack. This buff resets after not taking damage for 4s.
