Adaptability Turns Every STAB Move Into a Free 33% Damage Boost — How Pokémon’s 2x Ability Works (Plus the 8 Best Pokémon That Carry It)

Adaptability doesn’t add a new effect to a move. It doesn’t boost a stat, apply a status, or change accuracy. It just quietly rewrites one number — the same-type attack bonus — from ×1.5 to ×2.0 on every move that shares the user’s type. That’s a 33% jump over standard STAB (2.0 ÷ 1.5 = 1.333), applied automatically, every single turn, with zero setup cost.^[1] No other ability in the game does this much raw damage for this little investment.

The catch is that almost nothing has it. As of Regulation M-B, only five species carry Adaptability inside Pokémon Champions itself — and two of the mainline game’s best-known Adaptability users, Porygon-Z and Crawdaunt, aren’t in the Champions roster at all yet.^[7] This guide breaks down the exact damage math, ranks the 8 best Adaptability Pokémon across the whole franchise, and tells you plainly which ones you can actually build today versus which ones are mainline-VGC-only for now.

Quick Start: What Adaptability Actually Does

• Base effect: Same-type attack bonus goes from ×1.5 to ×2.0 on every move matching the user’s type^[1]
• No setup required: Unlike Swords Dance or weather abilities, it’s passive from turn one
• Coverage: Applies to every STAB move the Pokémon knows, not just its signature attack^[1]
• Terastallization stacks differently than you’d expect: Tera into your own type + Adaptability = ×2.25, not ×3.0^[2]
• Champions-legal right now: Basculegion, Mega Beedrill, Mega Lucario, Mega Glimmora, Basculin, and Dragalge (500 VP)^[6][7]
• Verified against: Regulation M-B (June 16 – September 1, 2026)^[10]

The Damage Math: 1.5x vs 2x vs Tera-Stacked

Here’s what that 33% actually looks like on real moves, before any other multiplier gets involved. Take a 100-base-power move like Crabhammer^[19]: no STAB at all leaves it at 100. Standard STAB pushes it to 150. Adaptability pushes the same move to 200 — a full 50 points of effective power that a same-species rival without the ability simply never gets access to.

That last row is the one most players get wrong. The intuitive assumption is that Adaptability’s 2x and Tera STAB’s usual 2x should multiply together into something enormous — they don’t. Bulbapedia’s move-mechanics documentation is explicit: “If such an attack is also affected by Adaptability, the STAB boost is increased to ×2.25,” not ×3.0 or higher.^[2] The extra 0.25 only appears when the Pokémon Terastallizes into a type it already had going in; Tera-ing into a brand-new type with Adaptability just gives you the same flat ×2.0 you’d get without Terastallizing at all.^[2] Stellar Tera type is a separate exception — Stellar-type moves ignore Adaptability’s boost entirely.^[1]

In practice, that means the correct Tera call for an Adaptability sweeper is almost always your primary STAB type, not a coverage type — the coverage-type Tera play that works for normal Pokémon actively costs an Adaptability user 25 effective power per 100 base power on its signature move.

Every Pokémon That Can Have Adaptability — And Who’s Actually Playable in Champions

Across the full Pokémon franchise, 14 species can roll Adaptability: Beedrill, Eevee, Corphish, Crawdaunt, Feebas, Lucario, Porygon-Z, all three Basculin forms, Skrelp, Dragalge, Yungoos, Gumshoos, Basculegion, and Glimmora.^[1][4] Pokémon Champions, however, runs a curated roster rather than the full National Pokédex, and it grows with each Regulation update rather than including every species at once.^[10] Cross-checking the Champions-specific ability database against Bulbapedia’s full list makes the gap obvious: only six roster entries across five species currently carry Adaptability in Champions.^[7]

We can’t say with certainty why Porygon-Z and Crawdaunt haven’t made the cut — Pokémon Champions adds roughly 20 new species per Regulation update, so exclusion right now most likely just means “not added yet” rather than a permanent design decision.^[10] Either way, if you’re specifically building a Champions team, the top half of this table is what matters today.

The 8 Best Pokémon With Adaptability, Ranked

1. Basculegion — the only one worth building around blind. Water/Ghost typing with a choice between Adaptability and Swift Swim, and the highest raw usage of any Adaptability Pokémon in the format.^[8] Current Regulation M-B numbers have it at B-tier, 24.64% usage, 51.34% win rate — down from the 53.2% win rate and 51.50% usage it posted under the previous Regulation M-A, but still the format’s most-played Adaptability user by a wide margin.^[9] The male form (112 Attack) wants Wave Crash and Last Respects; the female form (100 Sp. Atk) leans into Surf and Shadow Ball instead.^[13] Check the full Regulation tier list for how it slots into current team archetypes.

2. Mega Lucario — the original poster child. Fighting/Steel with 145 Attack and 140 Sp. Atk before any multiplier, Mega Lucario has carried Adaptability as its fixed Mega ability since the ability’s Generation VI debut.^[16] Close Combat at 120 base power becomes a 240-effective-power hit with Adaptability — few things in the format survive that twice.

3. Mega Beedrill — the glass cannon. 150 Attack and 145 Speed, both far above what a Bug/Poison type usually gets, paired with Adaptability as its fixed Mega ability.^[17] 15 base Sp. Atk means it’s a pure physical attacker — U-turn and Poison Jab both hit at full Adaptability value, but it folds to anything that outpaces or out-bulks it, since 40 base Defense offers no cushion for a second hit.

4. Mega Glimmora — the wallbreaker. 150 Sp. Atk on a Rock/Poison base that most teams aren’t built to resist twice, with Adaptability locked in as its Mega ability.^[14] Base Glimmora runs Toxic Debris before Mega Evolving, so the Adaptability payoff only kicks in once you commit the Mega slot — worth it specifically because Rock/Poison STAB coverage is otherwise mediocre without the multiplier doing the work.

5. Porygon-Z — the mainline-only Tera showcase. Not currently in the Champions roster, but 135 base Sp. Atk with a choice between Adaptability and Download makes it a Smogon SV staple.^[12] This is the cleanest real-world demonstration of the Tera-into-original-type math above: Tera Normal on a Normal-type Tri Attack turns an 80-base move into 180 effective power, the full ×2.25 stack.^[2] If you’re playing mainline VGC rather than Champions specifically, this is the highest-ceiling Adaptability user that exists right now.

6. Crawdaunt — the mainline glass-cannon wallbreaker. Also absent from the Champions roster today, but 120 base Attack plus a hidden-ability Adaptability makes Crabhammer (100 BP, high crit ratio) and Knock Off (65 BP, 97.5 against item-holders) genuinely hard to switch into in standard-format mainline play.^[11][19][20] Below-average 55 Speed and thin defenses mean it needs a teammate to force the opening rather than walking in on its own.

7. Dragalge — the budget support pick. Poison/Dragon with 123 base Sp. Def, Dragalge trades raw power for bulk — 97 Sp. Atk is respectable but not scary on its own.^[15] What makes it worth the 500 Victory Points is the combination: Toxic Spikes support plus an Adaptability-boosted Sludge Wave or Draco Meteor that most switch-ins don’t expect from a “support” Pokémon. Current M-B numbers put it at E-tier with just 1.27% usage^[9] — it’s a genuine underdog pick, not a meta staple, and the VP cost is the main reason it stays niche.

8. Basculin — the pre-evolution budget path. All three striped forms share 92 Attack and 98 Speed with Adaptability available as a straight regular-ability choice — no VP unlock required, no evolution item needed.^[18] It hits noticeably softer than its evolved form Basculegion, but if you haven’t banked enough VP to build the full line yet, this is the Adaptability sweeper you can field today instead of waiting.

Building an Adaptability Sweeper: Where to Put Your Stat Points

Because Adaptability already inflates your STAB damage before any stat investment, the temptation is to dump every available Stat Point into Attack or Sp. Atk and call it done. That’s a mistake with most of the Pokémon above. Basculegion and Mega Beedrill both sit on below-average bulk (65 and 40 base Defense respectively), so a pure offense spread gets them picked off by priority moves or a single revenge-kill before Adaptability’s damage ever matters. A more durable spread front-loads enough Speed to outrun the format’s common threats, puts the bulk of remaining points into the attacking stat that carries the STAB move, and only then fills HP or the secondary defense stat — not the reverse. If you haven’t worked through how Stat Points convert from the old EV system, the SP System Explained guide covers the exact 66-point pool and the 32-per-stat cap this spread has to fit inside.

Who Should Actually Use Adaptability

When Adaptability Isn’t the Right Pick

Adaptability only pays off on moves that share the user’s type — it does nothing for coverage moves, status moves, or off-type attacks. If a Pokémon’s best set leans on coverage more than STAB spam (a mixed attacker running two off-type moves and only one STAB move, for instance), a different ability that boosts the whole kit — Sheer Force, Technician, or a stat-boosting ability tied to its actual role — usually outperforms it. Skip Adaptability specifically when: the Pokémon’s signature set is coverage-heavy, when its base Attack/Sp. Atk is low enough that even a 33% boost doesn’t clear relevant damage thresholds, or when a defensive ability (Regenerator, Intimidate) matters more to its team role than raw output.

FAQ

Is Adaptability better than a Choice item boost?

They stack, so it’s not really either/or — but if you’re choosing between an Adaptability Pokémon and a non-Adaptability Pokémon both running Choice Band, the Adaptability user comes out ahead by the same 33% on every STAB move, permanently, without giving up the option to switch moves later the way a Choice item does.

Does Adaptability affect priority moves like Aqua Jet?

Yes — Adaptability boosts the base power calculation before priority is applied, so a same-type priority move gets the full 2x STAB just like any other move. Priority only affects turn order, not the damage formula.

Why isn’t Porygon-Z in Pokémon Champions if it’s such a strong Adaptability user?

Champions runs a curated roster that’s still expanding — roughly 20 new species arrive with each Regulation update, and the game simply hasn’t added Porygon-Z yet.^[10] There’s no official statement ruling it out permanently; it’s absent, not banned.

Is Dragalge worth 500 Victory Points just for Adaptability?

Only if you’re already planning to use it for its Toxic Spikes support role — as a pure Adaptability attacker it’s currently E-tier with 1.27% usage in Regulation M-B, which is too niche to justify the VP cost on damage output alone.^[9] If you’re deciding between VP purchases, our SP System Explained guide breaks down how Stat Points and Victory Points interact so you can weigh this against other unlocks.

Does Pokémon GO use Adaptability?

No — Pokémon GO’s Trainer Battle system doesn’t use the ability system at all, so none of this math applies there. If you’re coming from GO and want the equivalent competitive deep-dive for that game, see our Pokémon GO Battle League guide instead.
