Grumpig finds itself in the PU tier of competitive battling, where it stands out as among the best Pokémon in the tier. With good HP and Special Defense stats and a nice defensive ability in Thick Fat, Grumpig can take on a number of common Pokémon in the tier like Rotom-F, Ninetales, Regice, Monferno, and Mr. Mime. It has a number of good support options in Thunder Wave, Taunt, and Toxic, with the former being a great tool against offensive teams while the latter two help in its matchup against stall. Grumpig is best used as an offensive utility Pokémon that can use its well-rounded coverage in Shadow Ball and Focus Blast alongside Psychic to check threats like Monferno with effectiveness while having good utility with either Taunt or Thunder Wave. It can also run a specially defensive set that focuses more on a defensive niche and can be an effective counter to a number of special attackers. Grumpig's flaws lie in its low physical defense and weakness to Dark attacks, both of which can be easily exploited by powerful attackers like Dodrio and Leafeon. Grumpig also lacks reliable recovery, which means that it can be chipped down by entry hazards and constant attacks.
Grumpig is also viable in the Neverused (NU) tier of competitive battling. With Thick Fat to set it apart from other Psychic-types, Grumpig can switch into Fire- and Ice-type wallbreakers like Magmortar, Aurorus, and Charizard. It has a number of great support options in Thunder Wave, Whirlwind, Taunt, and Heal Bell, and its great Special Defense stat gives it a solid defensive niche in the tier. Grumpig is one of the few Psychic-types with access to Focus Blast in the tier, which allows for it to blast through Steel and Dark-types. Its best set is an offensive Calm Mind set that takes advantage of its solid coverage options to act as a nice win condition against opposing teams. It can also use an offensive stallbreaker set with Taunt alongside a status move like Thunder Wave or Toxic to hinder the opposing team quite a bit while maintaining decent offensive prowess. Lastly, Grumpig can run a specially defensive set that acts as a defensive utility Pokémon with support options and can be a more consistent check to certain offensive threats than the offensive sets. However, Grumpig has a lacking Defense stat that prevents it from checking Fighting-types like Primeape and Hariyama as effectively as its Psychic-type brethren. Grumpig is also vulnerable to being worn down in a match due to its lack of reliable recovery. It faces competition from Mesprit and Musharna as a bulky Psychic-type, which have better utility moves and superior physical bulk to work with that allows for them to check Fighting-types with much more effectiveness.
