The story is set in Lumiose City, where an urban redevelopment plan is underway to shape the city into a place that belongs to both people and Pokémon. Compared to Lumiose City as it appeared in the Pokémon X and  games, released in 2013, more greenery now adorns the city, alongside facilities with a cutting-edge feel.

In Lumiose City, spaces frequented by people—such as shopping arcades, cafés, and restaurants—coexist with more natural areas, such as waterfronts and verdant parks. At the center of Lumiose stands Prism Tower, the very symbol of the city.

While visiting Lumiose City, players will stay in an old hotel named Hotel Z and encounter the hotel’s owner, AZ—plus his partner Pokémon, Eternal Flower Floette, an unusual Floette that holds a black flower. This hotel will serve as players’ base of operations as they experience all sorts of adventures in Lumiose City alongside new and exciting characters, such as Urbain or Taunie—a new friend players will make throughout their adventures. The appearance players choose at the beginning of the game will determine which of the two they’ll meet.

As part of Lumiose’s urban redevelopment plan, driven by a large corporation called Quasartico Inc., the city has been outfitted with “wild zones” in an effort to help humans and Pokémon share the city. These areas are constructed using cutting-edge technology to give Pokémon places to live. Within wild zones, you can battle Pokémon and catch them by throwing Poké Balls.

The Pokémon Company International revealed new details for the Pokémon Legends: Z-A – Mega Dimension DLC. An extra side mission within the Pokémon Legends: Z-A game was also disclosed and is available now in-game.

Pokémon Legends: Z-A – Mega Dimension

The Pokémon Legends: Z-A – Mega Dimension DLC will be released on Wednesday, December 10, 2025, on the Nintendo Switch 2 and Nintendo Switch.

Venturing into Hyperspace Lumiose

In Pokémon Legends: Z-A – Mega Dimension, Trainers will revisit Lumiose as spatial distortions begin to form around the city. Donut chef Ansha and her companion, the Mythical Pokémon Hoopa, will guide players as they explore the mysterious dimension known as Hyperspace Lumiose. This not-quite Lumiose City is home to newly discovered Mega-Evolved Pokémon and other Pokémon not usually found in Lumiose, some of which can exceed the normal limit of Lv. 100 with hyperspace levels.

Hoopa’s powers are awakened when it receives one of Ansha’s donuts, transforming the distortions into portals to hyperspace. Ansha uses Berries to create various kinds of donuts that grant different effects in hyperspace, such as powering up your Pokémon. She can also use more potent Hyperspace Berries, which are useful for taking on the high-level Pokémon in Hyperspace Lumiose.

Trainers will be joined by new allies such as Korrina, a successor to a line of Mega Evolution gurus determined to encounter every Mega-Evolved Pokémon. Together with Team MZ, players will explore Hyperspace Lumiose, uncover its secrets, and tackle the strange events befalling Lumiose City.

Newly Discovered Mega-Evolved Pokémon

Mega Chimecho and Mega Baxcalibur will make their debut in Pokémon Legends: Z-A – Mega Dimension.

When Chimecho Mega Evolves, six smaller copies appear and flutter endlessly, even when no wind is blowing. When Chimecho cries, the echoes of its copies overlap and resonate, creating an intense sound-wave attack that can overwhelm any opponent.

Baxcalibur becomes even more formidable thanks to Mega Evolution, generating more ice energy and wielding a back blade that has grown larger and more powerful. With the sheer weight of this blade, it can cleave or smash nearly anything in its path. Players can obtain the Mega Stone needed to evolve Baxcalibur from the Z-A Battle Club as a reward for advancing in online Ranked Battles.

Extra Side Mission Now Available to Get Mythical Pokémon Diancie in Pokémon Legends: Z-A

Beginning Thursday, November 6, players can claim a Diancite Stone through the Mystery Gift feature in the Pokémon Legends: Z-A base game. This Diancite stone unlocks an opportunity to encounter and catch the Jewel Pokémon Diancie through an extra side mission titled “Shine Bright like a Gemstone.”

Once Trainers have claimed their Diancite via Mystery Gift, they can visit the Looker Bureau, where Mimi the Espurr—Emma’s partner Pokémon—will take a special interest in the Mega Stone, setting an extra side mission in motion. Completing this mission allows players to add Diancie to their team, then use the Diancite stone to Mega Evolve it into Mega Diancie, unveiling its radiant Mega Evolution in battle.

You can catch wild Pokémon living in wild zones or out and about in Lumiose City by aiming a Poké Ball at them and letting it fly. If the Pokémon doesn’t pop back out of the ball, you’ve successfully caught it!

Some Pokémon will flee immediately if they spot you, so hide out of sight or approach from behind to make yourself harder to notice. You can also battle Pokémon to lower their HP, making them easier to catch.

In previous titles in the Pokémon video game series, Pokémon took action once per turn. In Pokémon Legends: Z‑A, Trainers and their Pokémon will move around in real time during battles, and Pokémon will unleash their moves when their Trainers command them to.

In addition to type matchups, there will be new gameplay mechanics to consider, such as the precise timing for swapping out your Pokémon or using moves, the different lengths of time moves will take to launch, and how big an area the moves will impact. This unprecedented style of Pokémon battling is one of the most thrilling parts of this title.

After arriving in Lumiose, certain events will lead you to befriending a Pokémon that will become your adventuring partner, thus beginning your journey as a Pokémon Trainer. Which Pokémon will you set off on your adventure with: Chikorita, Tepig, or Totodile?

In Lumiose City, Trainers will sometimes be able to see Pokémon undergo Mega Evolution—a kind of Evolution that transcends standard Evolution. Effectively using Mega Evolution will likely be key to victory in Pokémon battles.

Pokémon Legends: Z-A is available for Nintendo Switch and Nintendo Switch 2.
