Bibarel

Simple: Once per short rest, you may double this Pokémon's Move modifier for a single attack or damage roll.

Unaware: When this Pokémon attacks an opponent, it ignores any stat changes the opponent has been affected with after the start of battle.

Moody: At the end of each long rest, this Pokémon rerolls on the nature table, replacing its nature with the result until the next long rest.
