You're staring at the screen, your 3DS is warm in your hands, and you've just realized that catching Alpha Sapphire all legendaries is a massive, sprawling chore that requires more than just a handful of Ultra Balls. It’s a grind. But honestly? It’s probably one of the most rewarding grinds in the entire Pokémon franchise because of how many heavy hitters are packed into one cartridge.
The Hoenn remakes, specifically Alpha Sapphire, are basically a museum of legendary history. Between the Primal Reversion of Kyogre and the bizarre requirements for the Regis, you aren't just playing a game; you’re solving a series of ancient, digital puzzles. If you’re looking to fill your boxes with every single deity and mythic beast available, you need a plan.
I've been through the "Soaring in the Sky" mechanics enough to tell you that timing is everything. Some of these guys only show up on certain days of the week, while others need very specific, almost nonsensical Pokémon in your party just to trigger an encounter. It’s weird. It’s clunky. It’s classic Game Freak.
The Big Three: Kyogre, Rayquaza, and Deoxys
The main story hits you with the heavyweights. Unlike the original GBA games, Alpha Sapphire gives you the "Delta Episode" post-game, which is where things get truly wild.
Kyogre and Primal Reversion
You’ll find Kyogre in the Cave of Origin. This isn't just a standard encounter anymore. Because of the Blue Orb, Kyogre undergoes Primal Reversion immediately. It becomes a Water/Electric-type nightmare (well, functionally, thanks to Primordial Sea) that hits like a freight train. You get this guy around the seventh gym. Don't waste your Master Ball here. You'll need it later for something with a much lower catch rate or a frustrating move-set.
The Delta Episode Duo
Once you beat the Elite Four, the game shifts into the Delta Episode. You'll head to Sky Pillar. This is where you grab Rayquaza. The catch? You actually have to catch it to proceed with the story. The game makes it slightly easier than usual, but don't get cocky.

Immediately after Rayquaza, you’re launched into space. Yes, space. You fight Deoxys. This is a level 80 encounter. If you accidentally knock it out, don't panic. You can respawn it by beating the Elite Four again, but who wants to do that? Save before the Rayquaza fight, because the Deoxys fight happens back-to-back.
The Regi Trio and the Braille Puzzle
If you want the Alpha Sapphire all legendaries experience, you have to deal with the Regis. This is the part of the game that makes people reach for a guide immediately. To even unlock the doors to Regirock, Regice, and Registeel, you need a Relicanth and a Wailord.
Go to Route 134. You need to dive and find a specific patch of Braille.
Put Relicanth in the first slot of your party. Put Wailord in the last. Read the wall. The earth shakes. Now, the three tombs across Hoenn are open.
- Regice: Found in Island Cave (Route 105). You have to wait two minutes in front of the Braille wall without moving.
- Regirock: Desert Ruins (Route 111). Move right twice, down twice, then use Strength.
- Registeel: Ancient Tomb (Route 120). Use Fly in the middle of the room.
The Regigigas Problem
Most people think they’re done after the trio. They aren't. To get Regigigas in Alpha Sapphire, you have to go back to Regice's cave during the day. But there’s a catch. Your Regice needs a nickname. It also needs to be holding a "cold item" like a Castiacone or Never-Melt Ice. It feels like a playground rumor from 2005, but it’s 100% real.
Mirage Spots: The Soaring Mechanic
This is where the bulk of the Alpha Sapphire all legendaries list lives. Once you get the Eon Flute from Steven Stone, you can summon Mega Latios (or Latias) to fly over the map. You’ll see red glimmers known as Mirage Spots.
The Johto Beasts and Ho-Oh/Lugia
In Alpha Sapphire, you specifically get Lugia. To find it, you need to go to Sea Mauville and find the Scanner. Give it to Captain Stern in Slateport. He gives you a Tidal Bell. Take that back to the basement of Sea Mauville.

For Raikou, Entei, and Suicune, you need a Lugia or Ho-Oh in your party while soaring.
- Raikou: Arrive at the Trackless Forest between 00 and 20 minutes past the hour.
- Entei: Between 20 and 40 minutes past the hour.
- Suicune: Between 40 and 00 minutes past the hour.
It’s a time-sensitive headache.
The Lake Trio and Sinnoh Dragons
To get Uxie, Mesprit, and Azelf, you need three Pokémon with max friendship in your party while soaring. Look for the Nameless Cavern.
- Mesprit: Day/Evening.
- Uxie: Late evening (20:00 - 21:00).
- Azelf: Middle of the night.
For Dialga, Palkia, and Giratina, it gets more complicated. In Alpha Sapphire, you can find Palkia naturally while soaring if you have the Lake Trio in your party. If you want Giratina? You need both Dialga (from Omega Ruby) and Palkia in your party at the same time. This means you have to trade with a friend or use Pokémon HOME.
Swords of Justice and the Gen 5 Cloud Trio
The Pathless Plain is where Virizion, Terrakion, and Cobalion hide. To make this spot appear, you need three Pokémon with maxed-out EVs (Effort Values) in your team.
The day of the week determines who you fight:
- Terrakion: Tuesday and Saturday.
- Virizion: Monday and Thursday.
- Cobalion: Wednesday, Friday, and Sunday.
Then there’s the gen 5 "Genies." You need a Castform in your party. Just Castform. Fly over Fortree City toward a big black cloud. You’ll find Thundurus in Alpha Sapphire. To get Landorus, you—you guessed it—need both Thundurus and Tornadus in your party.
Why This Matters for Your Dex
Completing the list of Alpha Sapphire all legendaries is basically a rite of passage for any serious collector. These aren't just entries in a digital book; they are some of the most powerful assets for the Battle Resort or for trading up to the newer Switch titles.

A lot of players get frustrated because they fly around for hours and see nothing. Usually, it's because the 3DS clock was tampered with. If you change your system time, the game freezes all "time-based events" for 24 to 48 hours. Don't do it. Just wait it out.
Also, stock up on Timer Balls. Many of these fights, especially against the Regis or the Sinnoh dragons, will drag on for twenty or thirty turns. After turn ten, Timer Balls become significantly more effective than Ultra Balls.
Actionable Steps for the Hunt
First, go to the Meadow near Mauville and catch a Ralts with the "Synchronize" ability. If that Ralts has a specific nature (like Timid or Adamant), the legendary you encounter has a 50% chance of having that same nature. It saves you hours of resetting.
Second, get a "Catcher Gallade." Teach it False Swipe and Hypnosis. False Swipe leaves the Pokémon with 1 HP, and Sleep has the highest catch-rate multiplier in the game.
Finally, check your "Buzz Nav" every day. It’ll tell you if a new Mirage Island has appeared. Some legendaries only show up on these fleeting islands, and if you miss the window, you're waiting another 24 hours.
Check your party. Check your clock. Get soaring. The Hoenn sky is crowded, but there's plenty of room in your PC boxes.
Legendaries Checklist for Alpha Sapphire
- Kyogre: Cave of Origin (Story).
- Latias: Southern Island (Story).
- Rayquaza: Sky Pillar (Delta Episode).
- Deoxys: Sky Pillar/Space (Delta Episode).
- Regirock/Regice/Registeel: Sealevel Vault/Island Cave/Ancient Tomb.
- Regigigas: Island Cave (Special conditions).
- Lugia: Sea Mauville (Scanner required).
- Raikou/Entei/Suicune: Trackless Forest (Lugia in party).
- Uxie/Mesprit/Azelf: Nameless Cavern (Friendship required).
- Palkia: Torn Sky (Lake Trio in party).
- Giratina: Torn Sky (Palkia and Dialga in party).
- Cobalion/Terrakion/Virizion: Pathless Plain (Max EVs required).
- Thundurus: Black Cloud near Fortree (Castform in party).
- Landorus: Black Cloud (Thundurus and Tornadus in party).
- Zekrom: Fabled Cave (Level 100 Pokémon in party).
- Kyurem: Gnarled Den (Zekrom and Reshiram in party).
Start by securing your False Swipe user. This is non-negotiable for the higher-level encounters like Deoxys or Zekrom where a single crit can ruin your afternoon. Once your catcher is ready, focus on the Lake Trio first, as their friendship requirement is the easiest hurdle to clear while you work on EV training for the Swords of Justice. If you're missing the version-exclusive halves like Dialga or Reshiram, use the GTS or local trades to bridge the gap before attempting the "trio masters" like Giratina or Kyurem.
