Grumpig can have one of two Abilities: Thick Fat, which reduces the amount of damage taken from Fire and Ice-Type moves by 50%; or Own Tempo, an Ability that makes it immune to becoming Confused.

Grumpig's Manga info is unknown at this time.
Grumpig finds itself in the Never-Utilized Tier of Competitive Battling. It is capable of taking Special Attacks thanks to a high Special Defense, and its Special Attack isn't a slouch either. But what sets Grumpig apart from other Psychic-Type Pokémon is a variety of Status Attacks, along with Thick Fat, which helps it to resist Fire-Type and Ice-Type attacks.
Repeated attacks are a serious problem for Grumpig because it doesn't have any method of consistent, reliable recovery other than Rest. Additionally, like many other Psychic-Types it is vulnerable to Physical attacks due to a low Defense.
