Motor Drive
Absorbs Electric moves, raising Speed one stage.
Full effect
Whenever an Electric-type move hits this Pokémon, its Speed rises one stage, negating any other effect on it. This ability will not take effect if this Pokémon is immune to Electric moves. Electric moves will ignore this Pokémon's Substitute. This effect includes non-damaging moves, i.e. Thunder Wave.
In game description
The Pokémon takes no damage when hit by Electric-type moves. Instead, its Speed stat is boosted.
Pokemon with Motor Drive
Using Motor Drive in Cobblemon
Abilities are passive and always active, so Motor Drive costs you nothing to run. If it is marked hidden on a species above, expect it to be harder to obtain: servers differ in whether hidden abilities come from breeding, an Ability Patch, or events.
See the Pokedex for which abilities each species can have, and IVs, EVs and breeding for how to actually pass one down.
