Pokémon Champions Mega Evolution is the active special battle mechanic supported by the Omni Ring, with eligible Pokémon transforming through their Mega setup during battle. Under the current Regulation M-C rules, you can Mega Evolve once per battle.
Pokémon Champions Mega Evolution is central to the current competitive format because M-C adds six more Mega forms without removing previously legal choices. The mechanic changes stats and can change Abilities, so the best Mega depends on the team plan rather than base-stat total alone.

How Mega Evolution changes a Pokémon
Mega Evolution transforms the Pokémon into its Mega form for battle, normally increasing overall stats and potentially changing its Ability.
Some Mega forms also change how the Pokémon should be positioned or supported.
Pokémon Champions Mega Evolution: only one Mega per battle
Regulation M-C keeps the one-Mega-per-battle rule. You can bring more than one Mega-capable Pokémon, but only one can actually transform.
Multiple candidates can still create team-preview uncertainty and give you different matchup plans.
New Mega Evolutions in Regulation M-C
M-C adds Mega Absol Z, Mega Salamence, Mega Garchomp Z, Mega Lucario Z, Mega Golisopod and Mega Baxcalibur.
Previously eligible Mega Evolutions remain available under the wider regulation pool.
Mega Stones from the Battle Pass
The current M-6 Premium Battle Pass includes Golisopite and Lucarionite Z alongside Golisopod and Lucario.
Pokémon notes that some Premium Mega Stones can later become available through the Shop for VP.
Pokémon Champions Mega Evolution in Singles and Doubles
Pokémon Champions Mega Evolution works in both Ranked Singles and Ranked Doubles when the selected Pokémon is legal.
Singles rewards team-preview flexibility, while Doubles adds partner support and two active opponents.
What the Omni Ring does not confirm
Pokémon’s current gameplay page says research may allow the Omni Ring to draw out other capabilities in the future.
It does not currently present every past-generation battle gimmick as a normal live Champions mechanic, so this page sticks to documented Mega Evolution.
How to choose a Mega for M-C
Start with the role your team actually needs. Mega Salamence, Mega Golisopod, Mega Baxcalibur and the Z Mega forms solve different problems.
Use the M-C Singles, Doubles and Best Mega Evolutions pages for current team shells, then adjust after testing.
When to use Pokémon Champions Mega Evolution
Mega Evolving as soon as a Pokémon enters the field is not always automatic. Sometimes the stronger stats or new Ability are needed immediately, while other matchups reward keeping the option hidden until the opposing team reveals its plan.
Because the current rules allow only one Mega Evolution per battle, committing one candidate also rules out every other Mega option on the team for that match.
Why teams can carry more than one Mega candidate
A team can include more than one Pokémon capable of Mega Evolution even though only one can transform. This gives you flexibility at team preview and lets the matchup decide which Mega form matters most.
That flexibility is particularly useful in Regulation M-C because the legal Mega pool is larger. A second candidate can cover a matchup that would otherwise force the same Mega choice every game.
