Mega Evolution in Pokémon Champions

1. Get the species' Mega Stone. They're in the Frontier Shop for 2,000 VP. The tutorial already gives you the Omni Ring (the ring that activates Mega Evolution) and 8 stones, and more come from the Battle Pass and events.
2. Give the stone to the Pokémon as its held item. Without the right stone in the item slot, there's no Mega.
3. Activate the Mega in battle, on whatever turn you want (on Switch, it's the R button).
4. Only 1 Mega per battle for each player. Once it evolves, the Pokémon stays Mega until the end of the match, even if it switches out.

The Mega Stone is the Pokémon's held item. So it gives up Sitrus Berry, Focus Sash, Life Orb or any other item. And item clause always applies: your team can't repeat items.

Since every stone is a different item, nothing stops you from bringing more than one Mega Stone on your team. Only one will Mega Evolve each match, but your opponent doesn't know which. That gives you flexibility and works as a bluff: in Reg M-C tournaments, teams carry almost 1.8 stones on average.

The game launched with 59 Megas in Regulation M-A. M-B raised that to 75, with the new Megas from Pokémon Legends: Z-A and the Mega Dimension DLC: Mega Dragonite, Mega Floette Eternal, Mega Delphox, Mega Froslass, Mega Excadrill, Mega Golurk, Mega Raichu X and Y, among others. Floette Eternal only reaches Champions through HOME, coming from Legends: Z-A.

Regulation M-C added 6 more Megas:

Legendary Megas (Mewtwo, Rayquaza, Latias, Latios and others) and Mega Zygarde are left out, because the roster has no legendaries.

The numbers below come from 371 Reg M-C tournaments on Limitless, with 15,709 teams, through Oct 29, 2026. The percentage is the share of teams carrying that Mega's stone.

Right behind them are Mega Froslass (5.2%), Mega Dragonite (4.7%) and Mega Raichu X (4.3%). Notice Garchomp: almost every Garchomp holding a stone uses Garchompite Z. Regular Garchompite shows up on only 2% of tournament Garchomp. The full list, with sets and partners, is on the Reg M-C tier list.

• Protect the Mega's turn. A Fake Out partner (like Incineroar or Rillaboom) holds off a threat while your Mega gets going.
• Check the Speed. Z Megas have 151 base Speed, and that changes who moves first in the meta. See the speed tiers.
• Do the math. Test in the damage calculator whether your Mega knocks out the targets that matter.
• Use the bluff. A second stone on your team keeps your opponent guessing at team preview.
• Copy what works. The tournament teams show how top players build around each Mega.
