Normalize

Full effect

This Pokémon's moves all act as if they were Normal-type. Moves that inflict typeless damage do so as usual. Moves of variable type, such as Hidden Power, are affected. They otherwise work as usual, however; Weather Ball, for example, is always forced to be Normal, but it still has doubled power and looks different during weather. As Thunder Wave is prevented by immunities, unlike most non-damaging moves, it does not affect Ghost-type Pokémon under the effect of this ability.

In game description

All the Pokémon’s moves become Normal type. The power of those moves is boosted a little.

Using Normalize in Cobblemon

Abilities are passive and always active, so Normalize 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.
