# Primal Pokémon and Primal Reversion

Sources checked: September 24, 2026

Primal Reversion temporarily restores the ancient power of Kyogre or Groudon. It is a separate mechanic from Mega Evolution. The orb requirements below apply to the core-series games that support it.

Mega Dimension also supports automatic orb-based Primal Reversion when entering battle. It does not drain Mega Power; player-owned forms do not gain the bosses’ simulated weather effects. GO instead spends Primal Energy for an eight-hour transformation, with its own bonuses.
