Pokemon Legends Z-A Post-Game & DLC Guide: Legendaries, Mega Dimension & Ranked

The credits roll and you're back in Lumiose City. The streets look the same. The Royale announcer is still going. But now there's a post-credits save file and the game has quietly unlocked about thirty more hours of stuff to do. The first thing you should do is go back to Hotel Z. AZ has new dialogue. More importantly, he gives you the Zygarde Cube, the item that lets you track and collect Zygarde Cells scattered across Lumiose City. There are a hundred cells total. They're hidden everywhere: inside trash cans, on rooftops, behind redevelopment projects you funded, in areas that only open up after certain Royale ranks. Collecting cells unlocks Zygarde's different formes. Ten cells gets you Zygarde 10%, the dog form. Fifty cells gives you 50%, the snake form. All one hundred cells lets you assemble Zygarde Complete Forme, which has a base stat total of 708 and looks like a Gundam. The cell hunt is tedious in spots, some cells only appear during specific weather or at specific times of day, but the payoff is worth it. Zygarde is catchable in a scripted encounter once you have enough cells for the forme you want. It's not a traditional legendary battle, more like a story sequence where Zygarde tests you before agreeing to join. The Complete Forme fight at the end of the cell hunt is genuinely difficult. Bring Ice types. Bring several. Xerneas and Yveltal are the post-game's other legendary targets. Both are tied to the main story's resolution, after Ange is dealt with, the energy disturbance attracts them to Lumiose City. Xerneas appears in the restored Botanic Gardens during clear weather. Yveltal appears near the cemetery district at night during fog. Both are level 70, both have their signature moves (Geomancy and Oblivion Wing respectively), and both will absolutely destroy an unprepared team. There's a trick to catching them that I wish someone had told me: they're scripted to use their signature moves on turn one of the encounter, and Geomancy takes a while to charge in real-time combat. If you rush Xerneas immediately, you can interrupt the charge and prevent the stat boost. Yveltal's Oblivion Wing heals it for a percentage of damage dealt, so bringing something with Taunt or disabling moves helps. The AI is aggressive, it will spam Oblivion Wing and heal through your damage if you let it. The real post-game sprawl is in the Mega Dimension DLC, which released in December 2025. You access it through a portal that opens in Prism Tower's basement after completing the main story and reaching a certain Royale rank. The portal leads to a place called Hyperspace Lumiose, a twisted, parallel-dimension version of the city where everything is slightly wrong. Buildings float. Gravity works differently in different districts. The sky is the wrong color. The DLC's central figure is Hoopa. Unbound Hoopa, specifically, the giant six-armed form that looks like a djinn. In this dimension, Hoopa has been pulling Pokemon from other regions through its rings, explaining why Pokemon that shouldn't be in Kalos are suddenly everywhere. The DLC plot involves calming Hoopa down and closing the dimensional rifts it's been creating. The DLC also adds three more legendaries: Groudon, Kyogre, and Rayquaza. Groudon appears in a volcanic recreation of District 5. Kyogre is in a flooded version of District 6's canal system. Rayquaza roams the distorted sky above Prism Tower. All three are level 80 encounters with unique arena mechanics, Groudon's arena has constant sunlight that boosts Fire moves, Kyogre's arena has rain, Rayquaza's has strong winds that affect flying movement. I caught Groudon first, partly because it's cool and partly because I had a solid Water type team from the main story. Kyogre took three attempts, its Origin Pulse in the rain hits the entire arena with very little dodge window. Rayquaza was the hardest mechanically because the flying arena means you're constantly managing altitude while fighting. It took five tries and a lot of Max Revives. Ranked Battles online is the other major post-game activity. Z-A's online mode runs seasonal ladders with Battle Spot style three-on-three singles or four-on-four doubles. The ranking system mirrors the offline Royale, letter ranks from Z to A, but against actual humans. Season rewards include exclusive Mega Stones, cosmetic items, and large sums of Pokedollars that feed back into the redevelopment system if you still have projects to fund. The ranked meta is still settling as of mid-2026. Mega Evolutions dominate, you basically need a Mega on your team to compete. Speedsters like Mega Lopunny and Mega Beedrill are popular because the real-time combat favors mobility. Mega Slowbro is a common tank pick. Mega Gardevoir and Mega Garchomp are everywhere. If you see a Mega Rayquaza on the opponent's team, they've been grinding the DLC. A few things that are notably absent from Z-A, and you should know about before you go looking for them. There is no breeding system. No daycare eggs. No hatching. If you want a specific nature or better stats, you use Nature Mints and Bottle Caps, both available from the Battle Arena shop. There are no traditional abilities, Pokemon have inherent traits that function similarly, but the ability system from previous games is gone. There's no held item system either, items are used actively during battle rather than held passively. These omissions are deliberate choices aligned with the real-time combat design. Breeding and held items made sense in a turn-based game where you had time to strategize. In real-time action, passive effects and held item management would slow things down. I miss breeding for shinies, but the Masuda Method was always a time sink anyway. Shiny hunting in Z-A works through the standard overworld encounter method, shiny Pokemon appear visibly shiny in the overworld before you engage them. The base rate is the usual 1/4096. The Shiny Charm is obtainable after completing the Pokedex (minus mythicals), which doubles odds to 1/2048. There are no chain fishing or SOS battle methods here. Just walking around and hoping. If you want a post-game checklist, here's roughly what I did: Zygarde cell hunt first (took about a week of casual play), then Xerneas and Yveltal (two evenings each), then the Mega Dimension DLC story (about 8-10 hours), then Groudon/Kyogre/Rayquaza (three sessions), and now I'm slowly climbing the Ranked ladder while finishing the Pokedex. I'm still missing about twenty entries, mostly rare spawns that require specific redevelopment projects I haven't funded yet. It's not an infinite endgame like Sword and Shield's Dynamax Adventures or Scarlet and Violet's Tera Raids. But what's there is quality over quantity. The legendary encounters are memorable. The DLC is actually substantial, not just a couple extra battles. And the Ranked ladder gives competitive players a reason to keep logging in between content drops.
