- Fits on stall as a dedicated answer to fire spam.
- Not overly useful for anything other than said Fire-Types
- Typing allows it to do its job so well because Fire-Types can't hit it hard with their coverage.
- Not really good for taking even resisted physical hits.
- No recovery outside of Lefites/Rest
Thick Fat
########
name: Thick Fat
move 1: Whirlwind
move 2: Heal Bell
move 3: Toxic / Thunder Wave
move 4: Psyshock
ability: Thick Fat
item: Leftovers
evs: 252 HP / 4 Def / 252 SpD
nature: Calm
Moves
========
- Whirlwind allows Grumpig to force out Fire types and other things that can't touch you and rack up hazard damage.
- Heal Bell is useful for removing status for Grumpig or its teammates.
- Toxic is for useful residual damage against opposing bulky teams and offense alike.
- Thunder Wave can be used instead to slow down the (usually) fast Fire types that you wall.
- Psyshock is important for hitting Cryogonal and various pokes weak to it like Dragalge and Vileplume. Hitting Cryogonal hard is espcially important.
- Psychic, alternatively, has higher base power and hits certain pokemon harder i.e. Weezing, but is generally inferior to Psyshock.
- RestTalk with Psyshock and Whirlwind is a possibility to give Grumpig status immunity and recovery, while avoiding being setup bait when asleep due to Whirlwind.
Set Details
========
- EVs are fairly standard for a Specially Defensive mon.
- Max SpDef allows you to stomach attacks from strong Fire types with relative ease.
- Thick Fat is one of the only reasons to use Grumpig. Its other abilities, Own Tempo and Gluttony, are either niche or completely useless on this set.
- Thick Fat allows you to act as a cold stop to Pyroar, non-Signal Beam Mesprit, Cryogonal, Jynx, and Ninetales.
- Audino makes a great partner due to its ability to pass large Wishes to Grumpig.
Usage Tips
========
- Grumpig is best brought in on special attackers, specifically Fire types, who are effectively walled by Grumpig's special bulk and access to Thick Fat.
- Also does well when in against boosting special sweepers, due to being able to force them out with Whirlwind/cripple them with status
- Grumpig is best used when you find yourself with a weakness to strong Fire/Ice types while also needing answers to threats like SubCM Uxie, non-Signal Beam Mesprit, CM/NP Ninetales, etc.
- You'll need an extra answer to SubCM Uxie since Grumpig won't be able to beat her in a last-mon scenario.
- Be sure to time your Heal Bells correctly as to not lose momentum
- Grumpig, by virtue of being a utility mon, can be used in all parts of the match, whenever you find yourself needing a switch-in to the likes of Typhlosion and Lilligant.
- Set aims to take advantage of the unusual traits (Whirlwind and Thick Fat) that give Grumpig a reason to be used over other Psychics.
Team Options
========
- A defensive Fairy is a great partner for Grumpig, since they can switch in easily on Bug and Dark type attacks. Slurpuff in particular supplies Wish and Aromatherapy support as well.
- Something in general to take on physical attackers is imperative due to Grumpig's poor physical defense.
- Grass types in general like having Grumpig around to take on Fire Types. Vileplume and Roselia in particular appreciate Grumpig's natural Psychic resistance, as well.
- Fighting types are extremely helpful for Grumpig, who eat up the aforementioned Bug and Dark attacks while beating Steel types who are resistant to Pig's Psychic STAB (and, if running Toxic, would be immune.)
- Gurdurr works well as a Fighting-Type partner due to its higher physical bulk than Hariyama, who's Thick Fat is unneeded when Grumpig can check Fire spam.
- Grumpig can at times have issues with special attackers who carry strong neutral attacks, specifically Water types. For this reason, Ferroseed is a useful partner as it switches into strong Water moves, can set up Rocks and Spikes as well as spread status with Thunder Wave.
- This set in general loves Spikes; they allow Grumpig to rack up damage with Whirlwind and help whittle down mons without the use of Toxic.
- Audino gets a special mention here due to its Ghost immunity and ability to pass huge wishes to Grumpig.
Other Options
########
- Taunt is pretty much just for Ferroseed, whom shut down completely aside from a weak Gyro Ball.
- The same goes for Magic Coat, which has the added bonus of preventing Taunt.
- Hidden Power Fire can also check Seed, but isn't entirely useful otherwise as it does poor damage to most Steel types.
- Grumpig has pretty good coverage options in Focus Blast, Signal Beam, and Psyshock, as well as a decent speed stat and adequate power, making an offensive set a possibility. However, Grumpig isn't too strong without max investment and still needs investment in Special Defense to do its primary purpose effectively.
Checks & Counters
########
- **Dark Types**: Grumpig has a lot of trouble with Dark types, especially Pawniard. Pokemon with Knock Off as coverage also have an easy time muscling through Grumpig.
- **Ghosts**: Despite being a special wall, Grumpig has trouble taking on strong Ghost Types, much as Mismagius.
- **Physical Attackers**: Grumpig's physical defense is lacking so even resisted hits are going to do a lot regardless. Its lack of resistances to many physical attacking types doesn't help it much, either.
- **Hazards**: Lack of recovery and being susceptible to all forms of hazards makes Grumpig easy to wear down.
