Still missing one member of the Hoenn trio after multiple wormhole runs? In Legends: Z-A, these captures are less about luck and more about sequencing requirements correctly.
This guide gives you the full route in order: unlock checks, donut recipes, portal locations, and battle plans for Groudon, Kyogre, and Rayquaza.
Follow the order exactly and use the checklist before each jump so every run moves you closer to a clean capture.
The core takeaway is simple: portal order, item prep, and encounter scripts decide this hunt more than reset volume.
PokemonLore keeps these routes and requirements updated, so you can return with a clear plan whenever events or patches shift the details.

Universal Catching Tips
Save before every entry. Stock at least 50 Timer Balls, 30 Ultra Balls, and a few Dusk Balls. Status moves like Spore, Thunder Wave, or Hypnosis boost catch rates; False Swipe helps with precision.
Primal Groudon Counter Strategy
Skip Water damage and lean on Ground attackers like Mega Garchomp or Mega Zygarde. Watch for Precipice Blades hitting the whole team and dodge lava eruptions. Use Wide Guard if your team has it.
Primal Kyogre Counter Strategy
Grass and Electric types shine. Origin Pulse hits multiple targets, so spread your team positioning.
Mega Rayquaza Counter Strategy
Ice and Fairy pressure are best. Keep a fast debuff or status user ready for the second phase.

Frequently Asked Questions
Where do I find the special berries for the donuts?
Farm ★4+ Ultra Wormhole missions in the Mega Dimension areas of Lumiose City. Hyper Berries drop from floating Poké Balls, and golden Poké Balls at zone completion often yield rarer berries.
What levels are the legendary Pokémon?
Primal Groudon and Primal Kyogre appear at Level 200. Rayquaza appears at Level 200 in both forms, then is captured at Level 80 after both phases.
Do I need to catch them in a specific order?
Groudon and Kyogre can be caught in any order, but Rayquaza only unlocks after both are captured.
What are the prerequisites for catching the Hoenn legendary trio?
Finish the Mega Dimension main story, catch Darkrai via Investigation File #6, reach 75,000 Investigation Points from ★4+ missions, and accept 'The Best Gift' at Hotel Z.
Can these legendaries be shiny?
Yes! All three have shiny variants available. However, they are shiny-locked during the first encounter. To shiny hunt them, you must complete the postgame and unlock repeatable Ultra Wormhole missions.
Catching Primal Groudon
Ultra Wormhole Mission 13: Crimson Legend
Step 4: Battle & Capture
Inside, you'll face Primal Groudon at Level 200. Reduce its HP carefully, inflict status conditions like Sleep or Paralysis, and use Timer Balls for the best catch rate.
Step 2: Craft Omega Old-Fashioned Donut
Head to Hotel Z's kitchen and craft the Omega Old-Fashioned Donut using the following flavor requirements:
Recommended Berry Combination: Hyper Tanga Berry x3, Hyper Payapa Berry x3, Hyper Roseli Berry x2. Any berries with the above flavor profile will work, but this combination reliably meets all requirements.
Bitter > 20
Fresh > 260
Sour > 160
Spicy > 160
Sweet > 260
Step 3: Enter the Ultra Wormhole
Travel to Wild Area 6 (western section). Look for the distinctive red Ultra Wormhole portal. Give the Omega Donut to Hoopa to enter.
Primal Groudon Battle Mechanics
Ground is the most reliable weakness during the Primal phase.
Lava tiles glow before they erupt; sprint or dodge out of them.
Mega Garchomp or Mega Zygarde are consistent counters.
Two-phase fight: regular Groudon first, Primal Groudon second. Save recovery for the second phase.
Water moves are blocked unless Groudon is stunned, so do not plan around Water damage.
Step 1: Accept the Quest
After accumulating 75,000 Investigation Points and completing Darkrai's questline, Ultra Wormhole Mission 13 'Crimson Legend' will become available at Hotel Z.
Catching Primal Kyogre
Ultra Wormhole Mission 14: Indigo Legend
Step 4: Battle & Capture
Primal Kyogre awaits at Level 200 inside the wormhole. Use Grass or Electric-type Pokémon to exploit its weaknesses. Status moves and Timer Balls will maximize your success rate.
Step 2: Craft Alpha Old-Fashioned Donut
At Hotel Z's kitchen, prepare the Alpha Old-Fashioned Donut with these flavor specifications:
Recommended Berry Combination: Hyper Qualot Berry x3, Hyper Wepear Berry x2, Hyper Pamtre Berry x2. Any berries with the above flavor profile will work.
Bitter > 180
Fresh > 370
Sour > 210
Spicy > 50
Sweet > 50
Step 3: Enter the Ultra Wormhole
Navigate to Wild Area 5 and locate the blue Ultra Wormhole portal. Present the Alpha Donut to Hoopa for entry.
Step 1: Accept the Quest
Similar to Groudon, Ultra Wormhole Mission 14 'Indigo Legend' requires 75,000 Investigation Points and Darkrai completion.
The Hoenn Legendary Trio
These three legendaries are among the most powerful Pokémon ever discovered, and catching all three unlocks special achievements and rewards in the Mega Dimension postgame.
The Continent Pokémon appears in Primal form with Ground/Fire typing and powerful Precipice Blades. In this DLC, Water moves are muted unless Groudon is stunned; Ice, Grass, and Ground coverage still matters.
Primal Groudon (Continent Pokémon)
The Sea Basin Pokémon manifests in Primal form with pure Water typing and strong Origin Pulse. Weak to Grass and Electric attacks.
Primal Kyogre (Sea Basin Pokémon)
The Sky High Pokémon reaches Mega Evolution without needing a Mega Stone, featuring Dragon/Flying typing. Weak to Ice (4x), Dragon, Fairy, and Rock.
Mega Rayquaza (Sky High Pokémon)

Catching Mega Rayquaza
Ultra Wormhole Mission 12: The Best Gift
Step 4: Two-Phase Battle
First, defeat regular Rayquaza (Level 200). Then immediately face Rogue Mega Rayquaza (Level 200). After defeating both forms, you can catch Rayquaza at Level 80. Bring Ice-type moves—Mega Rayquaza has a 4x Ice weakness despite Delta Stream reducing other Flying weaknesses.
Step 2: Craft Delta Old-Fashioned Donut
The Delta Donut requires the most precise flavor balance and special ingredients including Olivia Oil:
Recommended Berry Combination: Hyper Kelpsy Berry x3, Hyper Hondew Berry x2, Hyper Grepa Berry x2. Olivia Oil is a special ingredient obtained through Hotel Z quests.
Bitter > 40
Fresh > 390
Sour > 340
Spicy > 40
Sweet > 120
Step 3: Access the Sky Pillar Portal
Head to the rooftop of Hotel Z. An Emerald-colored Ultra Wormhole will appear. Give Hoopa the Delta Donut to access Hyperspace Sky Pillar.
Rayquaza Battle Mechanics
Back-to-back phases with no downtime; manage HP and PP carefully.
Delta Stream removes Flying-type weaknesses, but Ice remains a 4x weakness.
Bring Ice or Fairy specialists like Meganium, Xerneas, or Mega Glalie.
Prerequisite: Catch Both Groudon & Kyogre
Rayquaza's encounter ONLY unlocks after successfully catching both Primal Groudon and Primal Kyogre. Corbeau will then provide the Delta Donut recipe.
Step 1: Receive the Quest Update
After catching both titans, return to Hotel Z. Corbeau will update 'The Best Gift' quest and teach you the Delta Old-Fashioned Donut recipe.
