Catching all legendaries in Omega Ruby isn't just about finishing the Dex; it's a massive, multi-layered puzzle that Game Freak basically dropped on us back in 2014. If you’re coming back to Hoenn in 2026, you've probably realized that this game is actually more crowded with Legendaries than almost any other title in the series. It's wild. You’ve got the story-based encounters, the Delta Episode, and those weird, flickering red stars in the sky called Mirage Spots.
Honestly, the sheer volume is overwhelming if you don’t have a plan.
Most people think you just beat the Elite Four and the game is over. Wrong. That's when the real hunt starts. We're talking about space-time tears, specific party requirements, and even time-of-day mechanics that will make you want to pull your hair out if you miss the window by five minutes.
The Big Three: Hoenn's Core Trio
You obviously know the icons. Groudon is the face of the box. In Omega Ruby, you’re dealing with Primal Groudon at the Cave of Origin. It’s level 45. Don’t use your Master Ball here. Seriously, save it. You’ll want it for something much more annoying later.
Then there’s Latios.
You get him for free. No, really. Around the middle of the game, Steven takes you to Southern Island, and Latios just joins your party. He’s holding the Latiosite, which is huge for the "Soar" mechanic later on. If you want Latias, you’re usually out of luck unless you have an Eon Ticket, which was an old StreetPass event. Without it, you’re trading or using the GTS.
The Delta Episode and the Space God
Once you’re the Champion, the Delta Episode triggers. It’s a short, lore-heavy quest line involving Zinnia and a giant meteor.
- You'll head to the Sky Pillar.
- You catch Rayquaza (Level 70).
- You immediately go into a battle with Zinnia.
- Then, you fly into space—yes, space—to fight Deoxys.
Deoxys is Level 80. It’s a beast. If you accidentally knock it out, don't panic. You can actually respawn it by beating the Elite Four again. It’s one of the few times a "missable" legendary actually gives you a second chance.
Those Frustrating Regis
The Regi trio (Regirock, Regice, and Registeel) is basically a giant riddle. You need two specific Pokémon in your party to even start: Wailord and Relicanth.
Go to Route 134 and dive. You’ll find a cavern with Braille on the walls. Put Relicanth first in your party and Wailord last. Read the wall. The world shakes. Now, the three tombs across Hoenn are open.
- Regirock: Desert Ruins (Route 111).
- Regice: Island Cave (Route 105).
- Registeel: Ancient Tomb (Route 120).
But wait. There’s a fourth. Regigigas. To get the big boss, you have to go back to Regice’s cave during the day. You must have all three Regis in your party. Your Regice needs a nickname (kinda weird, but true) and it must be holding a "cold" item like Never-Melt Ice or a Casteliacone. If you don't do those specific things, the encounter won't trigger.
The Mirage Spot Chaos
This is where finding all legendaries in Omega Ruby gets complicated. When you use the Eon Flute to "Soar," you’ll see red glimmers over certain spots. These are Mirage Spots. Some are random, but others only appear if you have specific Pokémon in your party.
The Lake Trio and the Sinnoh Dragons
To find Uxie, Mesprit, and Azelf, you need three Pokémon with maximum happiness in your party. They live in the Nameless Cavern near Sootopolis. The catch? They rotate based on the time of day.
- Uxie: 8:00 PM to 8:59 PM.
- Mesprit: 9:00 PM to 3:59 AM.
- Azelf: 4:00 AM to 7:59 PM.
Once you have all three of these pixies in your party, soar near Dewford Town. You'll see a literal tear in the sky. In Omega Ruby, this is where you catch Palkia. If you want Giratina, you have to have both Palkia AND Dialga (from Alpha Sapphire) in your party and go back to that same tear.
The Johto Beasts and the Birds
To get Raikou, Entei, and Suicune, you need either Ho-Oh or Lugia in your team.
- Ho-Oh is exclusive to Omega Ruby. You find it at Sea Mauville after getting the Clear Bell from Captain Stern.
- Once you have Ho-Oh, soar to the Trackless Forest near Rustboro.
- The beast you find depends on the minute of the hour. Raikou appears in the first 20 minutes, Entei in the next 20, and Suicune in the final 20.
The Swords of Justice
To find Cobalion, Terrakion, and Virizion, you need three Pokémon with maxed-out EVs (Effort Values) in your party. They show up at the Pathless Plain.
- Virizion: Monday and Thursday.
- Terrakion: Tuesday and Saturday.
- Cobalion: Wednesday, Friday, and Sunday.
Version Exclusives You Need to Know
You can't get every single legendary just by playing Omega Ruby. You’re going to have to trade for the Alpha Sapphire exclusives if you want to unlock the "final" bosses of each group.

| If You Have (Omega Ruby) | You Need to Trade For (Alpha Sapphire) | To Unlock |
|---|---|---|
| Palkia | Dialga | Giratina |
| Reshiram | Zekrom | Kyurem |
| Tornadus | Thundurus | Landorus |
| Ho-Oh | Lugia | (No unlock, but needed for Beasts) |
Basically, Reshiram is at the Fabled Hole (requires a Level 100 Pokémon in your party). Tornadus is in a dark cloud over Fortree City (requires Castform in your party).
How to Not Fail Your Hunt
I’ve seen so many people accidentally kill a legendary and then save. Don't do that.
First, turn off Autosave if you're using a modern emulator or just be careful on the original 3DS hardware. Always save right in front of the portal or the Pokémon.
Bring a "Catcher" Pokémon. A Gallade with False Swipe and Hypnosis is the gold standard here. It can get the legendary down to 1 HP and put it to sleep, which massively boosts your capture rate.
Also, stock up on Timer Balls. Most legendary fights in this game go long. After 10 turns, Timer Balls start becoming more effective than Ultra Balls. By turn 30, they’re basically a cheat code.

Next Steps for Your Hunt:
- Check your party's Happiness levels in Verdanturf Town to prep for the Lake Trio.
- Head to Sea Mauville and find the Scanner; it's the gateway to Ho-Oh and the Johto beasts.
- Max out the EVs of at least three Pokémon using Super Training or vitamins to unlock the Pathless Plain.
- Ensure you have a Level 100 Pokémon in your PC to trigger the Reshiram encounter at the Fabled Hole.
