If you’ve been wondering which Pokémon will return, which regional variants make the cut, and—most importantly—which creatures are getting Mega Evolutions, we’ve got the complete breakdown of everything data miners have uncovered. Spoiler alert: it’s a LOT.
What We Know About Pokémon Legends Z-A: Mega Dimensions
The DLC is titled Mega Dimensions, and sales begin October 16, 2025, with the expansion releasing in 2026. Based on scrubbed game files, the community has compiled what appears to be the complete roster. We’re talking 140+ returning Pokémon spanning multiple generations, regional variants, and a brand-new Mega Evolution lineup that’ll reshape competitive gameplay.

The Mega Evolution Game-Changer: 15 New Mega Forms
Here’s where things get genuinely exciting. The DLC introduces Mega Evolutions for creatures that never had them before:
The Powerhouses:
- Baxcalibur Mega – A legendary dragon getting Mega form treatment
- Gimmighoul/Gholdengo Mega – Ghost-type getting massive boost
- Tatsugiri Mega – Water/Dragon receiving premier form
The Competitive Shifts:
- Lucario Z Mega – Already strong; about to dominate harder
- Garchomp Z Mega – Dragon/Ground powerhouse intensifies
- Crabominable Mega – Fighting/Ice getting surprise love
- Golisopod Mega – Aquatic bruiser enters Mega tier
- Magearna Mega – Mythical getting treatment
The Surprising Picks:
- Meowstic Mega – Psychic-type’s first Mega form
- Chimecho Mega – Humble sound-type ascends
- Absol Z Mega – Dark-type specialist gets enhanced form
- Staraptor Mega – Bird enthusiasts celebrate
- Scovilian Mega – Fire/Grass combination reimagined
This isn’t just power-creeping; it’s strategic rebalancing. Creatures previously considered mediocre suddenly gain competitive viability.
Regional Variants Making the Cut
The DLC respects regional diversity:
Alolan Forms: Meowth, Persian, Cubone, Marowak, Mr. Mime Galarian Forms: Meowth, Farfetch’d, Mr. Mime, Yamask Hisuian Forms: Qwilfish (getting Mega Evolution too!)
This suggests Legends Z-A will continue the “region respects history” philosophy. You’re not just getting classic Pokémon—you’re getting their evolved forms across different timelines.
Legendary & Mythical Representation
The roster includes proper legend treatment:
Legendary Trio Returns: Kobalion, Terrakion, Virizion, Keldeo (all Sinnoh Legendary Quartet members) Dimensional Legends: Latias, Latios, Kyogre, Groudon, Rayquaza Mythical Inclusions: Meleotta, Genesect, Marshadow, Zeraora, Melta, Magearna
These aren’t random inclusions—they’re setting up massive lore implications for Legends Z-A’s story.
What This Means for Your Pokémon Team
140+ returning Pokémon with 15 Mega Evolution forms means team diversity explodes. Your childhood favorites are likely returning. That underrated Pokémon you’ve always wanted to use probably got Mega Evolution treatment. Competitive players will frantically analyze which new Megas shift the meta.

The Elephant in the Room: Missing Pokémon

Pre-orders begin October 16, 2025, with full DLC release coming in 2026. That’s a long wait, but data miners assure us: the roster leak is comprehensive. Prepare your teams, study the new Mega forms, and get ready for what might be Pokémon’s most ambitious DLC expansion.

FAQs
Q: Are all these returning Pokémon confirmed or just leaked data?
A: These are based on scrubbed data from the main game’s files. While nothing is official until The Pokémon Company announces it, data mining is historically accurate for content already in game files. Official confirmation typically comes with DLC preview trailers closer to 2026 launch.
Q: Will my favorite Pokémon definitely get a Mega Evolution?
A: Not necessarily. Only 15 Mega Evolution forms were datamined. Hundreds of Pokémon are returning, but most won’t get Mega forms. If your favorite isn’t on the 15-Mega list, it’s still likely returning as a regular catchable Pokémon—just without the mega transformation.
