All 34 New Pokémon & Mega Evolutions Arrive in Pokémon Champions Regulation M‑C

On September 9, 2026, the Pokémon Champions community got a noticeable shake‑up. Regulation Set M‑C opened the doors to thirty‑four new Pokémon, six Mega Evolutions and a host of brand‑new held items. If you’ve been waiting for a chance to throw Rillaboom or a revamped Lucario onto your team, the time is finally here.

What makes this patch interesting is the blend of familiar powerhouses and the under‑dog candidates that rarely see the spotlight. Classic staples such as Rillaboom, Salamence, Cinderace and Indeedee make a triumphant return, while more niche choices like Squawkabilly, Swalot, Grapploct and Thievul slip into the roster, promising fresh strategic angles.

New Mega Evolutions

Six Mega forms have been added, each bringing a unique ability that can rewrite match‑ups:

• Mega Absol Z – Sharpness
• Mega Salamence – (no new ability, but a powerful Mega form)
• Mega Garchomp Z – Levitate
• Mega Lucario Z – Aura Guard
• Mega Golisopod – Emergency Exit
• Mega Baxcalibur – Thermal Exchange

Returning Pokémon

Thirty‑four species are now usable in Ranked Battles. Highlights include:

• Wigglytuff, Persian (including Alolan form)

• Arboliva, Mabosstiff, Baxcalibur
• Squawkabilly in four colour variants – green, blue, yellow and white plumage

• Normal Gem, Salamencite, Terrain Extender
• Electric Seed, Psychic Seed, Misty Seed, Grassy Seed
• Absolite Z, Garchompite Z, Lucarionite Z, Golisopite, Baxcalibrite

Abilities Tied to the Mega Forms

Each Mega brings a tailored ability designed to give it a niche advantage: Aura Guard for Mega Lucario Z, Levitate for Mega Garchomp Z, Sharpness for Mega Absol Z, Thermal Exchange for Mega Baxcalibur, Emergency Exit for Mega Golisopod, and the familiar Mega Salamence.

How Long Will This Regulation Last?

Regulation Set M‑C runs until December 2, 2026. During those three months, players can experiment with the new roster, test out the Mega forms, and see whether the unexpected choices—like Mega Golisopod or Mega Baxcalibur—can carve out a spot in the meta.

Overall, the update offers a generous toolbox for team‑builders. Whether you’re a veteran chasing the next dominant strategy or a newcomer looking for a fun surprise, Regulation M‑C gives you plenty to play with before the season resets.
