Although Grumpig seems outclassed by its fellow Psychic-types, it does have some advantages over them; Grumpig has higher Special Attack than Uxie, while Thick Fat allows it to take on Fire- and Ice-types much more easily, which is especially helpful as UU is filled with Pokemon such as Moltres, Blaziken, and Arcanine. Grumpig also has decent Speed, and excellent Special Defense and HP. This makes it a great supporter, which is further reinforced by its support movepool, which includes moves such as Taunt, Heal Bell, Reflect, and Light Screen. Unfortunately, Grumpig's average Defense doesn't help its Pursuit weakness at all, and its lack of recovery outside of Rest is disappointing. Overall, Grumpig is a decent defensive Pokemon, making it usable on stall teams and those with plenty of entry hazards.

~ Thunder Wave / Toxic
~ Reflect / Magic Coat
~ Psychic
252 HP / 80 Def / 176 SpD

Grumpig makes an excellent support Pokemon. Its good defenses, Thick Fat ability, and decent movepool are the main selling points. Heal Bell turns Grumpig into a good cleric, healing dangerous status, such as poison and burn, from its teammates; the second slot gives Grumpig its own status to play with, crippling the opponent with paralysis or poisoning them with Toxic. Reflect helps Grumpig compensate for its lower Defense stat, aiding it against Pursuit users, such as Absol and Spiritomb, while Magic Coat helps Grumpig bounce back status moves and other damaging moves like Leech Seed. Finally, Grumpig should use Psychic in the last slot to cover itself against Taunt users, though a lot of them will be Dark-types. Psychic also acts as STAB, hitting the likes of Venusaur and Toxicroak super effectively.

Calm Mind

Leftovers Thick Fat Timid
Moveset EVs
~ Calm Mind
~ Substitute
~ Psychic
~ Signal Beam / Hidden Power Fighting
252 HP / 4 SpD / 252 Spe

Grumpig's good HP, Thick Fat ability, and decent defenses make it a fine Calm Mind user. Calm Mind boosts its already high Special Defense, while the Special Attack boosts turn it into a dangerous sweeper. Substitute is a great move, blocking harmful status such as poison and burn, and Grumpig's Substitutes are difficult to break by special attackers after a few Calm Minds. Psychic is used for reliable STAB, and when paired with Signal Beam, it covers most types in UU barring Steel. Hidden Power Fighting can be used in the last slot instead of Signal Beam to cover Steel-types, but only if you don't mind losing to Psychic-types like Uxie. Focus Blast may also be used in the last slot, and although the lower accuracy is a turn-off, it does have the advantage of not lowering Grumpig's Speed IV that Hidden Power Fighting does.

Dual Screens

Light Clay Thick Fat Calm
Moveset EVs
~ Reflect
~ Light Screen
~ Psychic
~ Heal Bell / Thunder Wave
252 HP / 252 SpD / 4 Spe

This set makes the most of Grumpig's decent defenses, Thick Fat ability, and access to both of the dual screens. Reflect and Light Screen allow Grumpig to support its teammates by giving them an easier setup. Heal Bell also helps with supporting teammates by removing harmful status such as poison, burn, and sleep; this then makes a RestTalker a good choice for your team as it can then be woken up quickly. Alternatively, Thunder Wave or Toxic can be used in the last slot to spread status and cripple the opponent's team; any Spiritomb switching in certainly won't like being poisoned. Psychic is mainly used as filler and gives Grumpig something to do should it be Taunted, though this slot can be switched with Signal Beam to hit the Dark- and Psychic-types who will likely be switching in. Taunt may also be used to cripple slow set-up sweepers, such as Clefable and Slowking, as well as walls that attempt to lay entry hazards or spread status like Registeel. Light Clay is the item of choice as it prolongs the number of turns you will have screens on the field.

Choice Scarf / Choice Specs Thick Fat Timid / Modest
Moveset EVs
~ Trick
~ Psychic
~ Shadow Ball
~ Focus Blast
4 HP / 252 SpA / 252 Spe

With a Choice item equipped, Grumpig turns into a potent threat and revenge killer; utilize Trick to cripple walls and setup sweepers like Clefable. Psychic is Grumpig's most powerful STAB move and hits Fighting- and Poison-types, such as Hariyama and Toxicroak, super effectively. Shadow Ball and Focus Blast provide perfect type coverage, hitting everything in UU for at least neutral damage; you may use Hidden Power Fighting instead of Focus Blast for its higher accuracy, though the drop in power isn't usually worth it. Modest Choice Specs Grumpig can 2HKO Tank Registeel with Focus Blast, and 3HKO Chansey.

Other Options

Grumpig can use RestTalk to remedy its lack of recovery, though it's pretty unreliable considering the number of weaknesses Grumpig has to common moves. Counter is an interesting option and allows Grumpig to take on many physical attackers, especially Fighting-types, by hitting them back twice as hard. On the special side, Grumpig may use Mirror Coat to bounce back powerful hits such as Mismagius's Shadow Ball. Utilizing a ParaFusion set may be tempting with Confuse Ray and Thunder Wave, though it's pretty luck-based and very risky. Finally, Grumpig may use Trick Room along with a Quiet or Sassy nature, obtaining a Speed stat of 148, slow enough to outrun most of UU under Trick Room conditions, especially since it has the defenses to take an attack while setting up, and support the team afterwards.

Checks and Counters

Chansey, Clefable, and Registeel are by far the best counters for Grumpig; they all have high Special Defense, many support moves to cripple Grumpig, and two of them have reliable recovery moves. They'd better watch out for Grumpig with Trick or Choice Specs Focus Blast though; using Stealth Rock is an easy way to see if Grumpig doesn't have Leftovers, so be wary of Trick. Dark-types, particularly Spiritomb, also make excellent counters as they have an immunity to Psychic, good Special Defense, and powerful STAB moves, such as Sucker Punch and Pursuit. Drapion is another good choice as it can set up Toxic Spikes, or shut down Grumpig with Taunt; Skuntank is also a good, uncommon counter. Almost any Pokemon with good Special Defense and access to a super effective attack can take on Grumpig. Just watch out for Choice sets, as Choice Specs boosted attacks may hurt.
