03. Alomomola

Water · Regenerator (99.9%) / Healer / Hydration (irrelevant) · VR A+ · 2026-04 Usage 24.40% (#1 in the format) · Base stats 165 / 75 / 80 / 40 / 45 / 65 (HP / Atk / Def / SpA / SpD / Spe) · The format’s #1 glue: a 534-HP Regenerator pivot that Wishes its team to health, Flip-Turns momentum, and is hard to keep down.

You will meet this fish more than any other Pokémon in the tier. It scores zero offense and almost zero KOs — its entire job is to make the other five slots functional. For an aggressive-offense player it is rarely your problem to “kill”; it is the wall you must go around or outpace the team it supports.

Format role

Alomomola is the connective tissue of balance and bulky-offense. A 165-base HP pool funneled through Regenerator means it recovers ~33% every time it pivots out, so it can soak a hit, Flip Turn, and come back full a turn later — passive recovery no other water-pivot matches. It is run almost exclusively to (a) blanket-check physical attackers behind huge HP+Def, (b) pass Wish to frailer breakers/pivots, and (c) keep momentum with Flip Turn. Note the VR/usage tension — A+ on the council list but the single most-used mon in the meta (24.40%); it is more central than its tier implies, and it belongs in most balance discussions. See 02-viability-tiers and the Regenerator note in 01-mechanics-natdex.

Sets

The spread split in the block is purely physical-wall vs. special-wall investment; pick by what your team is weak to. All spreads run 0 Spe.

Assault Vest pivot (43.6% of items) — the special-leaning wall

Alomomola @ Assault Vest
Ability: Regenerator
Nature: Sassy
EVs: 252 HP / 4 Def / 252 SpD   (Sassy:252/0/4/0/252/0 13.4%)
- Flip Turn      (99.9%)
- Mirror Coat    (39.0%)
- Knock Off      (31.2%)
- Liquidation    (12.3%) / Play Rough (15.5%)

AV blocks status-recovery moves, so this set drops Wish/Protect and instead becomes a special tank that Flip-Turns and punishes special attackers with Mirror Coat. With 252 SpD+ it answers a startling range of special threats and then refunds their damage doubled.

Heavy-Duty Boots / Rocky Helmet utility wall (26.7% / 24.1% items) — the Wish-passer

Alomomola @ Heavy-Duty Boots  (or Rocky Helmet)
Ability: Regenerator
Nature: Relaxed
EVs: 252 HP / 252 Def / 4 SpD   (Relaxed:4/0/252/0/252/0 16.7% & 252/252 variants)
- Flip Turn      (99.9%)
- Wish           (56.5%)
- Protect        (54.5%)
- Toxic (53.2%) / Knock Off (31.2%)

The classic glue build. Boots ignores hazards on the repeated entries it makes constantly; Rocky Helmet + Regenerator turns it into a contact-punishing physical sponge that heals off the chip. Wish + Protect is the team’s recovery engine; Toxic puts a clock on opposing walls.

Move usage from the block: Flip Turn 99.9%, Wish 56.5%, Protect 54.5%, Toxic 53.2%, Mirror Coat 39.0%, Knock Off 31.2%, Aqua Jet 21.7%, Play Rough 15.5%, Liquidation 12.3%. Ability is Regenerator 99.9% — Healer/Hydration are noise.

What it does

It pivots. Every turn Alomomola is in, the question is “Flip Turn into my breaker, or stay and Wish/Protect?” Regenerator means switching it out heals it, and Flip Turn switches it out with momentum, so it almost never has to commit to a passive recovery turn unless Wish-stalling. The two builds split cleanly:

• Boots/Helmet Wish set is the team backbone. It sits on physical attackers, Wishes the active or a pivoted-in breaker to full, and Toxics walls it can’t break. Protect banks the Wish and scouts. Knock Off strips items (huge vs. opposing Boots/AV mons). This is the version that makes Landorus-Therian/Gholdengo cores tick.
• Assault Vest set flips the matchup against special attackers and is the one that punishes you: Mirror Coat returns 2× the special damage it just took, so firing a strong special move into a healthy AV Alomomola can hand back a KO. It cannot Wish (AV blocks status moves), so it leans on Regenerator alone and Flip Turn chip.

Key interactions for the offense player: it does nothing offensively — Flip Turn is ~10% chip, its only “damage” is Knock Off utility and the occasional Mirror Coat blowup. It is weak to Grass and Electric (2×) and, critically, to Kyurem’s Freeze-Dry specifically because that Ice move hits Water super-effectively; ordinary Ice coverage is not a Water weakness. It loathes Knock Off itself (loses Boots/AV/Helmet → hazard-vulnerable, weaker). It barely pressures Grass-types, Electrics, or many setup users unless it lands the right Toxic / Knock Off / Mirror Coat sequence.

Load-bearing calcs

Defensive anchors (via dmgcalc): 252 HP = 534 HP; 252+ Def (Relaxed) = 284 Def; 252+ SpD (Sassy) = 207 SpD. These are the standard block spreads; all ranges below are computed against them.

• Kyurem Choice Specs Freeze-Dry vs 252 HP / 252+ SpD Alomomola: 428-506 (80.1-94.8%) [heavy 2HKO; OHKO only after major chip]. Assault Vest lowers that into a firmer 2HKO rather than an OHKO, and Ice Beam is neutral and much weaker. Freeze-Dry is why Kyurem forces progress against the fish; generic Ice coverage does not delete it.
• Serperior Leaf Storm vs 252 HP / 252+ SpD Alomomola: 372–438 (69.7–82.0%) [2HKO]. Grass 2× through full SpD; with Contrary every Leaf Storm gets stronger, so Serperior wins the long game outright. (Serperior appears as a check in the block at 73.9% — this is why.)
• Ogerpon-Wellspring Ivy Cudgel (Wellspring Mask x1.2) vs 252 HP / 252+ Def Alomomola: 85-100 (15.9-18.7%) [~6HKO]. Water resists Water, so Ivy Cudgel is not the click. Do not turn that calc into a blanket wall claim: Power Whip is super-effective, Knock Off strips Boots/Leftovers, and Ogerpon-W can still force progress if Alomomola is asked to answer it repeatedly.
• Zamazenta Body Press vs 252 HP / 252+ Def Alomomola: 109–130 (20.4–24.3%) [4–5HKO]. The fish absorbs unboosted Body Press Zamazenta comfortably. If your wincon is Press Zama, Alomomola is a brick wall without chip, boosts, or partner pressure — bring a partner or a Spike stack.
• Melmetal Double Iron Bash vs 252 HP / 252+ Def Alomomola: ~194–230 over two hits (36.3–43.1%) [3HKO]. Melmetal is the #1 listed switch-in (84.7) but only KOes 8.5% of the time — it checks via the Toxic/flinch/PP war, it does not break. Confirms the matchup is a stall, not a kill.
• Alomomola Flip Turn vs 0/0 Gholdengo: ~9–13% [pure chip]. Its own offense is a rounding error; Flip Turn exists for momentum, never damage. Almost never play around Alomomola “doing damage” (Mirror Coat is the lone exception).

Checks & counters

From the block (switch-out % shows how it concedes rather than dies):

Checks (they wall the matchup / win the 1v1):

• Melmetal (84.7) — eats Alomomola’s attacks, ignores Toxic via Steel typing, and threatens Thunder Wave + Double Iron Bash flinch pressure; only 8.5% KO rate but Alo can’t progress.
• Ferrothorn (84.3) — Grass/Steel typing + Leech Seed + Knock; Alo barely damages it (2.0% KO rate) and cannot land Toxic. Iron Barbs + Helmet still punishes Flip Turn because it makes contact, so Alo can lose momentum HP even when it pivots safely.
• Gliscor (70.7) / Toxapex (62.1) — Poison Heal / Regenerator walls that out-passive it; the Toxic war goes nowhere (Pex 0% KOed).

Soft checks / breakers (open it up):

• Kyurem (74.8) - Specs Freeze-Dry heavily chunks max-SpD and forces progress; Ice Beam is neutral and not the click.
• Serperior (73.9) / Ogerpon-Wellspring (63.3, but see calc caveat) — Grass breaks it; note Ogerpon-W’s Water move does not (it’s the Grass/Ivy-Cudgel + chip + Knock that wears it, plus it pressures Alo’s teammates).
• Scizor-Mega (66.4) / Kingambit (61.2) / Ursaluna (61.1) — strong physical/priority breakers that 2–3HKO past Wish if it’s already chipped; Knock Off + hazards do the real work.

How Alo fights back: Mirror Coat punishes special attackers that try to muscle through the AV set; Knock Off cripples item-reliant checks; Toxic clocks the passive walls above; Regenerator wins every PP/longevity war it isn’t being 2HKOed in.

★ Offense angle

You will almost never run Alomomola on aggressive offense — it generates no pressure and clashes with your tempo. Your job is to break it or render it irrelevant, and the meta gives you clean tools:

1. Bring Freeze-Dry, not generic Ice. Kyurem Specs Freeze-Dry is the anti-Water hit that heavily chunks special-wall Alomomola and 2HKOes less specially invested sets; Ice Beam is neutral and does not delete AV/max-SpD Mola. Build this Water-breaking coverage into your breaker slot rather than dedicating a turn to “outlasting” it (you will lose the longevity war).
2. Stack hazards and Knock the Boots. Garchomp/Ting-Lu Spikes + a Knock Off lead removes its Boots → Spike chip + Toxic from your side + no Regenerator-on-switch math = the Wish engine collapses. Alomomola off Boots becomes much easier to convert into hazard progress.
3. Don’t waste your special attacker into a healthy AV fish — Mirror Coat refunds the hit doubled. Lead with physical pressure or force the AV set out before committing a Specs click.
4. Recognize what it can’t stop. It walls physical waters and Body Press Zama, but it does nothing to Grass/Electric setup or to Iron Valiant/Tapu Lele-style special breakers that can force progress while respecting Mirror Coat. Do not blindly feed Mirror Coat a survivable special hit; use Psyshock, chip, Knock, or setup pressure to make the exchange favorable. Identify which of your breakers Alomomola “answers” and pair it with a partner it doesn’t — twin breakers sharing no checks is how you bury the fish.

The trap to avoid: trying to out-tempo Alomomola with chip. Regenerator + Wish + Protect + huge HP means it wins any patience contest. You go through it (Ice, Grass, Knock+hazards) or you ignore it and dismantle the slower team it glues together.

Top teammates & cores

From the block’s top-10 partners (2026-04):

Strongest cores:

• Alomomola + Landorus-Therian (32.1%) — the format’s default balance spine: Lando provides Stealth Rock, U-turn momentum, and Intimidate; Alomomola provides Wish recovery, Flip Turn, and a physical blanket. Together they pivot-loop into whatever breaker the team runs. See 02-viability-tiers for where this spine sits in the meta.
• Alomomola + Gholdengo (20.8%) — the “wish a fragile denier to full” core: Gholdengo’s Good as Gold absorbs targeted status moves that pressure Alo, Ghost typing spinblocks for the team’s hazards, and Alomomola keeps the otherwise-frail wincon topped off between Make It Rain volleys.

As an offense builder, treat these cores as the opposing structure you are dismantling — your Ice breaker + hazard stack + twin-breaker plan exists precisely to crack the Alo+Lando / Alo+Ghold balance backbone — see the ★ Offense angle above for the full breakdown.
