Pokémon Pokopia hides 13 Legendary and Mythical Pokémon across its world, and each one has its own trigger. Some join you automatically as you clear the main story, others roam Dream Islands, a few only show up after you build a specific kit, and the rarest demand crafted summoning items. Below is exactly what unlocks each one and how you confirm it worked.
Quick answer: Clear the main story areas for Kyogre, Raikou, Volcanion, and Mewtwo; use specific Dream Island dolls for the Legendary Beasts; build the three Legendary Bird kits in Palette Town; then craft the Tidal Bell and Clear Bell for Lugia and Ho-Oh. Mew unlocks after you collect all 27 Mysterious Slates.
Story encounters: Kyogre, Raikou, Volcanion, and Mewtwo
Four Legendaries enter your Pokédex just by progressing the main quests, so you cannot miss them on a normal playthrough. Kyogre is the first you meet, appearing once you finish the Yawn Up A Storm quest. Raikou shows up after you complete the main story in Bleak Beach, while Volcanion appears once you wrap up Rocky Ridges. Mewtwo is a story encounter at the top of the Celadon Department Store and leaves immediately after a cutscene.
| Pokémon | Trigger |
|---|---|
| Kyogre | Finish the Yawn Up A Storm quest |
| Raikou | Complete the Bleak Beach main story |
| Volcanion | Finish the Rocky Ridges quests |
| Mewtwo | Complete the build project at the top of the Celadon Department Store |
The story encounter only adds these Pokémon to your Pokédex. To have some of them actually move into your town, you need to meet them again. Volcanion, for example, returns to Rocky Ridges after you throw a second party there, raising the area’s mood back to 100 and then setting off a cannon and fireworks. Raikou and Mewtwo are re-encountered through Dream Islands, covered next.
Dream Island Legendaries: Raikou, Entei, Suicune, and Mewtwo
The three Legendary Beasts and Mewtwo can be found by traveling to Dream Islands, and the doll you use steers which island type you land on. The doll narrows down the encounter, but it does not guarantee it. You often need to revisit the same island several times before the Pokémon appears, because the exact layout is random each trip.
| Pokémon | Doll |
|---|---|
| Raikou | Pikachu Doll |
| Entei | Arcanine Doll (Ditto Doll possible) |
| Suicune | Eevee Doll (Ditto Doll if lucky) |
| Mewtwo | Dragonite Doll (also Ditto Dream Islands) |
When you reach a Dream Island, check the two caves that cross beneath the island’s main mountain. That spot usually holds either a Legendary Pokémon, a piece of lore, or a new outfit. Once you talk to the Legendary there, you can bring it back to your region and set it up in a home. For Raikou specifically, the Pikachu doll is how you re-encounter and recruit it after the Bleak Beach story.
Legendary Birds: build the kits in Palette Town
Articuno, Zapdos, and Moltres each require you to buy and build a dedicated kit, and they appear after a short cutscene once the build is complete. The kits are sold at the Pokémon Center, but they are demanding. Each one needs 15 Pokémon to help with construction plus a stack of rare materials. Palette Town is a good build site because the birds need a lot of open space.
| Bird | Kit | Materials |
|---|---|---|
| Articuno | Freezing Chambers | 50 Stone, 50 Ice, 10 Crystal Fragments, 10 PokéMetal |
| Zapdos | Abandoned Power Plant | 50 Copper Ingot, 50 Iron Ingot, 50 Sea Glass Fragments, 50 Brick, 10 PokéMetal |
| Moltres | Altar of the Flame | 50 Copper Ingot, 50 Gold Ingot, 50 Lava Block, 10 PokéMetal |
Once all three birds are befriended, they can travel between your towns and move into houses. Finishing the trio also matters for the next step, because it unlocks one of the two summoning recipes.
Lugia and Ho-Oh: craft the Tidal Bell and Clear Bell
Both of these Legendaries fly overhead during normal play and drop feathers as they pass. Lugia leaves Silver Feathers, and Ho-Oh leaves Rainbow Feathers. You collect those feathers, craft a bell, and then ring it when the Pokémon next flies over a large open area to bring it down for a befriending cutscene.
| Pokémon | Item | Recipe | Prerequisite |
|---|---|---|---|
| Lugia | Tidal Bell | 5 Silver Feathers, 5 Rare PokéMetal | Befriend Articuno, Zapdos, and Moltres |
| Ho-Oh | Clear Bell | 5 Rainbow Feathers, 5 Rare PokéMetal | Befriend Raikou, Entei, and Suicune |
After you have all three Legendary Birds, your Pokédex hands you the Tidal Bell recipe. The matching Clear Bell recipe unlocks after you have all three Legendary Beasts. Place the finished bell in a wide-open space, wait for the Pokémon to pass, and ring it to start the cutscene.
Mew: collect every Mysterious Slate
Mew is the final entry in the current Pokédex and the only Mythical here. It is not tied to a doll or a kit. Instead, you have to gather 27 different Mysterious Slates, which appear at random inside shiny patches of ground around the world.
One thing worth keeping in mind once these Pokémon move in: Legendary and Mythical Pokémon raise the Environment level of whichever area you settle them in more than ordinary Pokémon do. As you raise their comfort level, lifting the entire area’s environment becomes easier, so placing them thoughtfully pays off well beyond just filling out the Pokédex.
