Hatterene

Hatterene is the engine of Reg M-A’s Trick Room scene and one of the few Pokémon in the format that auto-sets a terrainTerrainmechanicField effects that last 5 turns and boost or protect grounded Pokémon — Grassy, Psychic, Electric, and Misty each do something different.Click to read more → on switch-in. Bulky enough to survive most attacks, slow enough to thrive under reversed Speed, and immune to status disruption thanks to Magic BounceMagic BounceabilityReflects status moves back at the user — Taunt, sleep moves, weather-changing moves, and hazards all bounce.Click to read more →.

Why it’s foundational

Hatterene does three things almost no other Pokémon does:

1. Sets Trick Room reliably. With base 29 Speed and respectable bulk, it almost always gets Trick RoomTrick RoomstrategyFor 5 turns, slower Pokémon move first. Reverses the entire speed game — a strategy that builds teams around very slow attackers.Click to read more → up before being KO’d — even into the teeth of opposing pressure.
2. Auto-sets Misty Terrain. Misty Surge fires the moment Hatterene touches the field. Sleep moves (SporeSporemoveA Grass-type move that inflicts sleep with 100% accuracy — the most reliable sleep move in the game.Click to read more →, Hypnosis), Thunder WaveThunder WavemoveParalyzes the target — halving their Speed and giving a 25% chance each turn to be unable to move.Click to read more →, and Will-O-WispWill-O-WispmoveBurns the target — halving their physical Attack and dealing 1/16 max HP chip damage every turn.Click to read more → all fail against grounded targets while it’s up.
3. Reflects status with Magic Bounce. TauntTauntmovePrevents the target from using status moves for 3 turns — shuts down Trick Room setters, Tailwind users, and redirectors in doubles.Click to read more →, EncoreEncoremoveForces the target to repeat their last move for 3 turns — devastating in doubles when it traps a Protect or harmless status move.Click to read more →, Leech SeedLeech SeedmovePlants a seed on the target that drains 1/8 of their max HP every turn, healing the Pokémon that planted it.Click to read more →, and any other status move targeting Hatterene bounces back to the user. The setter that teams want to disrupt is the setter that punishes those disruption attempts.

Common sets

• Trick Room anchor (most common) — Trick Room, Dazzling Gleam, Psychic, ProtectProtectmoveA move that makes the user immune to all moves for one turn. Fails if used consecutively.Click to read more →. Sitrus Berry or Mental Herb. Quiet nature, full HP and Special Attack investment, 0 Speed IVs.
• Misty Surge support — Helping HandHelping HandmoveA +5 priority move that boosts the partner's next move by 1.5× — doubles-only support that amplifies damage without attacking.Click to read more →, Misty Explosion, Dazzling Gleam, Trick Room. Pivots between offensive support and TR setup as the game develops.
• Mystical Fire utility — Mystical Fire, Dazzling Gleam, Psychic, Trick Room. Drops opposing Special Attack with every Mystical Fire — pairs especially well with Reuniclus or other special TR sweepers.

Common partners

• Reuniclus — second TR setter. Magic Guard ignores Life Orb recoil and chip; Trick Room redundancy means at least one of the two almost always gets it up.
• Conkeldurr / Torkoal — slow, hard-hitting sweepers that come online under Trick Room.

• IncineroarIncineroarpokemonThe most-used Pokémon in Reg M-A. Defines doubles tempo with Fake Out, Intimidate on every switch, and Parting Shot pivots.Click to read more → — pre-softens incoming damage so Hatterene can survive an extra turn under pressure.

What beats it

Steel-type moves are 2× super-effective and Hatterene has no Steel resistance. Iron Head, Bullet Punch, and Gigaton Hammer all threaten clean KOs. Dark-type moves likewise hit it for super-effective damage and bypass its low Speed via priority Sucker Punch. The bigger structural answer is Taunt with priority — WhimsicottWhimsicottpokemonPrankster utility lead. Priority Tailwind, Encore, and Sunny Day let it dictate tempo against teams that thought they had it.Click to read more →’s PranksterPranksterabilityAn ability that gives all Status moves +1 priority — they go before almost everything, even if the Pokémon is slow.Click to read more → Taunt would be ideal except Magic Bounce bounces it back. Faster non-Prankster Taunters (Mega AerodactylMega AerodactylmegaTough Claws boosts contact moves by 1.3× on top of Aerodactyl's already blistering 150 base Speed — the fastest Mega in the format.Click to read more → under TailwindTailwindmoveDoubles the Speed of every Pokémon on your side for 4 turns.
