🆕 Everything New in Pokémon Champions Regulation M-C

Regulation M-C added 24 Pokémon and six Mega Evolutions on 9 September 2026, including the first Z Mega Evolutions. Full breakdown of what changed, what is confirmed, and what is still unrevealed.

Regulation M-C went live on 8 September 2026 at 7:00 p.m. PDT (9 September, 02:00 UTC) and runs until 1 December 2026. It is the third regulation set of the Pokémon Champions competitive year, following M-A and M-B, and it is purely additive: nothing legal in M-B was removed.

What actually changed

• 24 newly available Pokémon, confirmed by The Pokémon Company.
• Six new Mega Evolutions — three standard, three Z Megas.
• Six new Mega Stones to go with them.
• No bans. Every Pokémon legal in M-A and M-B stays legal.

The six new Mega Evolutions

This is the headline of M-C, and it splits into two groups. Three are conventional new Megas: Mega Salamence, Mega Golisopod and Mega Baxcalibur. The other three are the first Z Mega Evolutions — a second Mega form for Pokémon that already had one.

Z Mega Evolutions

• Mega Absol Z — ability Sharpness, which boosts the power of cutting moves by 1.5×.
• Mega Garchomp Z — ability Levitate, granting immunity to Ground-type moves and avoiding entry-hazard effects.
• Mega Lucario Z — ability Aura Break, which halves the damage taken from contact attacks.

Standard Mega Evolutions

Mega Salamence, Mega Golisopod and Mega Baxcalibur are confirmed to exist, but as of this writing their abilities, typings and base stats have not been officially revealed. We are not going to guess them. This guide updates the moment they are published.

The six new Mega Stones

• Absolite Z, Garchompite Z, Lucarionite Z — for the three Z Megas.
• Baxcalibrite, Golisopite, Salamencite — for the three standard Megas.

The new Pokémon

The Pokémon Company confirmed 24 newly available Pokémon but did not publish the list — in-game, it sits under Recruit → Recruit Pokémon → Roster Info. Published lists therefore vary, mostly because outlets count form variants differently. These are the additions that independent sources agree on:

• Galar starters: Rillaboom, Cinderace, Inteleon
• Mega recipients: Salamence, Golisopod, Baxcalibur
• Others: Wigglytuff, Persian, Alolan Persian, Mr. Mime, Swalot, Gogoat, Thievul, Toxtricity, Grapploct, Perrserker, Pincurchin, Indeedee, Arboliva, Squawkabilly, Mabosstiff

Published lists disagreed on three entries — Pawmot, Farfetch'd and Sirfetch'd. We checked each against live Regulation M-C ladder data and all three are legal: each list had simply missed some. That makes 24 Pokémon, or 26 entries once Toxtricity's Low Key form and female Indeedee are counted separately.

The early M-C meta

The tier list now runs on live Regulation M-C ladder data, and several of the additions went straight into the top tier. Rillaboom opened the format as the most-used Pokémon, and Salamence, Golisopod and female Indeedee all entered the top ten alongside established picks like Sneasler, Incineroar and Kingambit. On Garchomp, Garchompite Z immediately became one of its two most-held items alongside Life Orb — the Z Mega is being taken seriously from week one.

What to do first

1. Check whether your existing team is still legal — it almost certainly is, since M-C removed nothing.
2. Look at whether a Z Mega is worth the slot. Garchomp is already the most-used Pokémon in the format, and Levitate changes how it is checked.
3. Hold off on rebuilding around the new Megas until their abilities and stats are published.
4. Come back once ladder data settles — early-format usage is noisy and the first week rarely reflects where a meta lands.
