Pokémon Legends ZA Mega Dimension expansion arrives Dec 10, 2025

Nintendo, Game Freak and The Pokémon Company announced on Thursday that the Mega Dimension expansion for Pokémon Legends ZA will arrive on December 10, 2025, for Nintendo Switch and Switch 2. A new trailer and accompanying materials revealed story details centered on Hoopa, multiple new Mega Evolutions, returning Pokémon, an increase to the series' traditional level cap, and a separate, immediately available distribution that lets players obtain Diancie and its Mega Stone without buying the paid DLC.

The trailer sets the DLC in Lumiose City, where Team MZ encounters mysterious distortions linked to an alternate realm called Hyperspace Lumiose. Ansha, a new trainer featured in the footage, appears with the Mischief Pokémon Hoopa and can open portals that lead players into that alternate version of the city. "Just when Team MZ's efforts seem to have restored peace to Lumiose City, something strange begins to happen: mysterious distortions start forming all around town," the trailer says.

Game materials confirm several new Mega Evolutions, including distinct X and Y forms for Raichu and newly revealed Mega forms for Chimecho and Baxcalibur. Diancie will also be obtainable in-game...
