🆕 All 22 New Pokémon Added in Pokémon Champions Reg M-B

Complete list of every new Pokémon added in Reg M-B: Sceptile, Blaziken, Swampert, Mawile, Metagross, Gholdengo, Grimmsnarl, Annihilape and more. Day-1 usage stats and tier placements included.

Regulation M-B is the biggest content drop Pokémon Champions has seen since launch. 22 new species join the legal roster, the meta has reshuffled almost overnight, and the format now runs on Switch, iOS and Android in parallel. Here is the full list of every new Pokémon you can now build around, with day-one usage data and a read on each one's competitive role.

What changed in Reg M-B

M-B runs from June 16 through September 1, 2026 (sometimes called Season 3 by the community). It adds 22 base species, 16 new Mega forms across 15 species, 31 new items, and a small set of move and ability tweaks aimed at trimming the most centralizing M-A Pokémon. Nothing was removed from the roster, so M-A specialists keep their entire toolkit and can plug new picks in alongside. See the full M-B patch notes for every stat and move change.

S and A-tier hitters (the early movers)

Three new species cracked the top 15 in their first week. These are the ones to learn first. Cross-reference with the live M-B tier list for the latest day-by-day movement.

• Grimmsnarl (#10 at 18% usage). Prankster screens user with Reflect, Light Screen, Spirit Break and Spirit Trick coverage. Lost Thunder Wave and False Surrender in M-B but is still the strongest screens setter in the format. Pairs with any frail offense.
• Gholdengo (#11 at 17%). Good as Gold blocks all opposing status moves outright. Make It Rain is now 95% accuracy with a 2-stage Sp. Atk drop instead of 1, but the Steel/Ghost typing and complete status immunity keep it relevant. Choice Scarf is the most common item.
• Annihilape (8%). Defiant punishes Intimidate hard, Rage Fist scales with damage taken. M-B reset the Rage Fist counter on switch, so you have to commit to a long stay-in. Pairs poorly with Incineroar opponents (Fake Out interrupts the scaling).

B-tier with real upside

Mid-tier picks with a clear path to the top tier once players settle in.

• Mawile (5% — only the base form usage; the Mega is even higher). Huge Power doubles physical Attack on Mega Evolution. Steel/Fairy resists Dragon and Dark spam, walls Sucker Punch from Kingambit, threatens Fairy STAB Play Rough back. The Mega Stone competes for the Mega slot with Kingambit and Garchomp.
• Eelektross (5%). Mega Eelektross gains Eelevate, a new ability covered in the M-B abilities guide. Ground immune, immune to entry hazards, and snowballs stat boosts on every KO. Easily the best new sweeper if you can land the first kill.
• Sceptile (4%). Mega Sceptile gains the Dragon type and Lightning Rod, which absorbs Electric moves into a +1 Sp. Atk boost. Now learns Earth Power in M-B, which gives it coverage on Steel and Fire walls.

Mainline returnees

The five returning Mega-capable species from older Pokémon games. Their canonical XY/ORAS abilities and stats carry over.

• Blaziken. Speed Boost on the Mega is back. The fastest snowball in the format if it survives one turn.
• Swampert. Swift Swim on Mega Swampert. Mandatory consideration on any Pelipper rain build. Now learns Wave Crash in M-B for a physical Water STAB option.
• Metagross. Tough Claws Mega, lost Heavy Slam and Knock Off but still has Meteor Mash, Bullet Punch priority and Ice Punch coverage. The defensive Steel-type of choice.
• Sceptile (covered above).
• Mawile (covered above).

Champions-exclusive Mega debuts

Eleven species gain a brand-new Mega in M-B that does not exist in any mainline game. Each one comes with custom stats, ability, and often a type change. We cover them fully in the All 16 New Mega Evolutions guide, but here are the base species joining the roster alongside their Mega.

• Raichu gains Mega Raichu X (Electric Surge) and Mega Raichu Y (No Guard). Raichu itself was already on the roster — the Mega Stones are the new content.
• Staraptor (Contrary). Type changes to Fighting/Flying on Mega.
• Scolipede (Shell Armor). Loses 50 Speed on Mega but gains massive bulk and a crit-immune body.
• Scrafty (Intimidate). Lost Parting Shot in M-B but is the new go-to Intimidator outside of Incineroar.
• Pyroar (Fire Mane). New ability, +50% Fire moves with no HP threshold. Becomes Normal/Fire on Mega Evolution.
• Malamar (Contrary). Becomes Psychic/Dark on Mega, pairs ability-shared with Staraptor.
• Barbaracle (Tough Claws). Type changes to Fighting/Rock on Mega.
• Dragalge (Regenerator). Mega Dragalge pivots in and out healing 1/3 HP, with 163 Sp. Def behind a 132 Sp. Atk.
• Falinks (Defiant). +2 Attack every time an opponent lowers a stat. The hard counter to Intimidate spam.

Niche additions and tech picks

Five species with little day-one usage but interesting toolkits. Worth knowing for matchup prep even if you do not run them yourself.

• Vileplume (Grass/Poison). Effect Spore as the hidden ability is a stealthy way to punish contact moves. Sleep Powder + Quiver Dance support set is the play.
• Qwilfish (Water/Poison). Intimidate option that drops Spikes or Toxic Spikes on the field. Faster hazard setter than Glimmora.
• Musharna (Psychic). Trick Room setter alternative to Hatterene. Synchronize lets you bounce status back at burner leads.
• Overqwil (Dark/Poison). The Hisuian Qwilfish evolution joined separately. Swift Swim sweeper for rain teams that wants Dark coverage.
• Houndstone (Ghost). Sand Rush in Sand teams, Last Respects scaling like Basculegion. Niche but real.

How the meta shifted

Three big movements out of the M-A meta are worth noting alongside the new arrivals.

• Sinistcha rocketed from 19% to 39% usage to take the #1 spot. The Grass/Ghost Trick Room enabler now anchors the meta.
• Basculegion fell from 47% (M-A #1) to 25% as new Choice Scarf alternatives diluted its niche.
• Whimsicott moved up from B-tier to A-tier (27% usage). The Prankster Tailwind + Encore combo is the most reliable speed control answer to Sinistcha-led Trick Room teams.

Where to start building

If you only have time to learn one new species this week, start with Grimmsnarl. Prankster screens fit every archetype, the toolkit is forgiving for new players, and the day-one usage shows it is already winning at the high level.

If you want a project pick that will pay off later in M-B, build around Mega Eelektross. The Eelevate ability is unique in the format and the snowball ceiling is the highest of any new mega.

Open the StrataDex Team Builder, slot in any new species, and Deep Dive+ will tell you which of your existing M-A picks pair well and which ones get redundant. Most M-A teams need 0 to 2 swaps to be M-B-ready, not a full rebuild.
