Battle formats

Single Battles

Bring 6, pick 3 — one Pokémon on the field at a time. Team Preview shows both squads before you lock your three.

Double Battles

The official VGC format — two Pokémon per side, so spread moves, Protect and redirection all come into play.

Battle modes

Ranked

Climb the ladder with Victory Points across seasonal regulations.

Casual

Practice matchups and teams with no rank on the line.

Private

Battle friends directly in custom rooms.

Champions rules

  • ● Each regulation defines its own eligible Pokémon and held items. Check the current list before choosing a team.
  • ● Mega Evolution returns as a core mechanic via the Omni Ring — one Mega per battle, and it stays Mega for the rest of the match even after switching out.
  • ● Move PP is standardized to fixed values (8 / 12 / 16 / 20).
  • ● Some Pokémon have adjusted learnsets, and Mega Evolution includes forms introduced in Pokémon Legends: Z-A.

Regulation sets

Ranked seasons rotate through regulation sets that change the legal roster and banlist.
