The list above separates Alolan Persian from standard Persian because both forms are available in the M-C roster. Other species such as Toxtricity, Indeedee and Squawkabilly also have multiple forms represented in the live roster, but they are still the same named Pokémon Champions Regulation M-C Pokémon species for the official 24-addition count.
Which New Pokémon Were Announced Before Launch?
Before the update arrived, only part of the Pokémon Champions Regulation M-C Pokémon list was public. Pokémon specifically named Rillaboom and showed Salamence, Golisopod and Baxcalibur alongside their new Mega Evolutions.
The September 9 live roster filled in the remaining additions. That is why some pre-launch lists contain only four standard Pokémon and six Megas while the final M-C roster is much larger.
Do Previous Regulation Pokémon Stay Legal?
Yes. Pokémon Champions Regulation M-C Pokémon are additions rather than a complete replacement roster. The official M-C announcement says Pokémon eligible in previous Ranked Battle regulation sets remain eligible.
That means established M-B teams do not automatically become illegal simply because M-C has started. Players can keep using previously eligible choices and rebuild only where the new additions or balance changes make it worthwhile.
Which New Pokémon Matter Most Competitively?
The official announcement singles out Rillaboom as an example of a returning Pokémon with a strong VGC history. Salamence, Golisopod and Baxcalibur are also headline Pokémon Champions Regulation M-C Pokémon because all three receive new Mega Evolutions.
Indeedee and Pincurchin also expand terrain options, while several added held items include Terrain Extender and all four terrain Seeds. Those are factual mechanical additions; how dominant any individual Pokémon becomes will depend on live M-C results rather than pre-season prediction.
How Long Does Regulation M-C Last?
Pokémon Champions Regulation M-C Pokémon become legal from 02:00 UTC on September 9, 2026. Regulation Set M-C is scheduled to run until 01:59 UTC on December 2, 2026.
The official rules continue the one-Mega-Evolution-per-battle structure and the existing duplicate-held-item restriction.
