Hyper Cutter
Prevents Attack from being lowered by other Pokémon.
Full effect
This Pokémon's Attack cannot be lowered by other Pokémon. This ability does not prevent any Attack losses other than stat modifiers, such as the Attack cut from a burn. This Pokémon can still be passed negative Attack modifiers through Heart Swap or Power Swap.
In game description
The Pokémon's prized, mighty pincers prevent other Pokémon from lowering its Attack stat.

Using Hyper Cutter in Cobblemon
Abilities are passive and always active, so Hyper Cutter 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.
