Why can’t I find Regigigas in OR/AS?

Question

I have all three titans, Regice is nicknamed, and holding a casteliacone. I caught them all last year in this save, so I passed the time limit. The little girl in pacilog town keeps saying something about six dots opening three doors instead of telling me the story. I’ve exited and re-entered the room, I’ve soft reset, waited days, she won’t change her story. What am I doing wrong?

Extra info:
- all she says is, “Six dots open three doors”. The dialog never changes
- I’ve talked to her with all regi’s in my party
- I’ve used different ice items
- Only Regice is nicknamed
- I caught them in 2020
- My cartridge is legit
- time base events are working as normal
- I’ve waited until daytime before going to the location
- I’ve done this before I’ve beaten the E4, and after
- I have left my cartridge in the same ds for multiple days to ensure time based events were working
- I’m not willing to restart my save to see if it’s my save file or not because this is my Oak challenge save file and I have like a hundred hours and multiple full odds shinies
- I have not beaten the post-game story

2026 Update..
This question remains unresolved as to why this happened. I did check just now, and verified all My regi's have the same OT/ID. I remember catching catching them all authentically.
About 6 months ago, a friend readdressed this question with me. I changed Regice's name. We tried waiting another two days with it in a different console, in case that was the issue. I went back to all the regi caves, just to verify, and the little girl never changed her speech. I decided to make a drastic move... I used PKSM to reset the all the regi's encounter... and it worked. I recaught all the Regis, and then went and caught Regigigas without issue. And the little girl said what she was supposed to, before and after.

Now, with PKSM mentioned, I did modify my save file before Badge #1 to give myself Pokeballs, the Shiny Charm, and Surf, to make the game a bit more enjoyable during the grind. I did not modify the game any further, and not with the Regi's encounters. I highly doubt that was the cause of this occurrence, as there's been countless other people who have experienced this same thing with no resolution, and I highly doubt all of them did the same thing.

I am confident this is a bug in the code rather than user error.. what's left is for us to determine how, why, and a proper remedy. I plan to continue to investigate this, to see if I can recite the bug, and to see how each flag being modified impacts it. I also plan on datamining the flag and Regigigas encounter as soon as source code becomes available. I also do have saves backed up all the way to 2020. I might even go back to the beginning of the game and see....

I'd assume all 3 regis are in your party...

---

yup (filler

---

Entered the back room of the Cave?

---

Did you try talking to the girl with the Regis in your party?

---

Yup (filler x2)

---

Regigigas can only be battled after catching/defeating the Box-Art Legendary (Kyogre/Groudon). Mayhaps this is the dilemma.

---

All 8 badges obtained

---

Guys here’s a video that should hopefully answer all potential questions https://youtu.be/Cofc0k9zaDU

I have found what all 4 stories Girl tells you: https://segmentnext.com/how-to-capture-regigigas-in-pokemon-omega-ruby-alpha-sapphire/

But he said you’ll need to wait in the middle when it’s bright and Hoenn is overflowing with natural energy. I wonder if he meant you can’t meet it at night.

But you’ll need to have three of its friends with you to meet it… I wonder what Pokémon they area. Does it have to do with the six dots?

But you’ll need to have something cold to meet it… I wonder what he meant. Ice cream, maybe?

He told me that it comes to visit this iceberg kind of Pokémon. I can only think of one type of iceberg Pokémon…

Also found this. Idk if you can recapture them in a row...
It even says to enter from the center

Wait for 24 hours after acquiring Regice, Regirock, and Registeel in a row,

---

This is peculiar. I would try giving Regice a NeverMeltIce instead of a Castelia Cone. Thats another item that works.

Also, make sure your other Regis are not nicknamed, because that will prevent Regigigas from appearing

---

Are you sure about the last part? My Regis are nicknamed and I can still get Regigigas to appear.

---

Only the ice boi is nicknamed, and I tried it with never melt ice too

---

To encounter Regigigas, you must have the 3 Regi in your team - Regirock, Regice and Registeel. After capturing them, go to Pacifidlog Town and visit the northeast house. You'll find a girl there who'll tell you about Regigagas. Make sure that your Regice has a nickname and is holding an Ice-related item such as Never-Melt Ice (Shoal Cave), CasteliaCone (Trick House) or an Icy Rock (Weather Institute). If you didn't nickname your Regice, talk to the Name Rater in Slateport City and give it a nickname. Another thing to consider is that Regigigas won't show up until a day after you've captured the Regi trio. Lastly, Regigigas can only be found during daytime (11:00 - 17:59).

I would go through this step by step even if you've already done it. It's possible that you didn't talk to the girl in Pacifidlog with all the Regis and nicknames and held items in your party.

---

Baron please look at the video I posted which is very clear evidence I did all of the above

---

I am aware, I watched the video, I am just making sure.

Also make sure you have not changed the ds clock or put your cartridge in a different ds in the last 24 hours

---

It’s now been over 24 hours since I’ve written this and there has been no change and I have not removed the cartridge since
I’ve been regijected

---

I don't think we can help you then

---

Anecdotal evidence, but this thread https://old.reddit.com/r/pokemon/comments/dv0bwg suggests that clearing the Pokemon League again will cause the event to trigger.

---

I have never cleared the e4 to begin with. Is it a postgame exclusive perhaps?

---

When I was about to catch Regigigas I already defeated the Elite Four, completed the Delta Episode, and as well rematch the Elite Four. I can tell you it's a post-game exclusive legendary cuz it doesn't appear in the Hoenn Pokedex.

---

@cinchilada, the national dex is obtained prior to defeating the 8th badge. I have most of the national dex caught, and every other legend, without beating the E4.

---

Bro go beat the e4...

---

(Weary) alright I’ll go test it one (1) more time and immediately crush the E4, and go back and see if there’s a difference. Sometime this week because adult moment

---

I beat the E4 and went back and nothing happened. I haven’t even removed the cartridge from my DS since this happened, and all other time events are working.

---

No idea if this would change anything, but has there EVER been a Regigigas on this save file? And are all of the 3 Regis yours from this save?

---

All three Regis i caught on this save myself, and I never had a regigigas on this save. I checked my dex

---

Are you sure your copy isn't fake/corrupted?

---

Positive.

---

Don't know if it'll make a difference, but did you try talking to the girl with Regice at the front of your party?

---

Wait 24 hours after you beat the e4

---

I think the 3DS Clock needs to be in the same year that you caught the Regice and nicknamed it and as well you caught the other Regis. Try changing the 3DS Clock to 2020 to see if it makes a difference. Remember to wait 24 hours after you changed the clock

---

6 months without response from OP...
@Scarlet Did you already get Regigigas?

---

I did not get regi.
I did not try your previous suggestion because I originally tried to get them the year I caught them, and it did not work.

---

I honestly think this is a poorly documented glitch, that’s been passed over due to how weird and obscure it is. I’ve seen a few other threads and videos with the *exact* same situation as me, with the same dialog, that all remain unsolved. Does anyone happen to know where I can hire a dataminer to look into this?

---

Have you entered the second room?

---

Did you ever get this resolved?
I feel like the most likely answer is that you caught one or more of the Regis in a different game. You can confirm this is the case by reading the dialogue in Island Cave — if you don't get any message at all, you didn't catch all the Regis in the same game.

---

I did not catch the Regis in any other games. I have the video showing it, and the save file to proof that all are the same OT and ID. It did not get resolved. I ended up having to hack the game to manually reset the flag to catch Regigigas. For some reason, resetting Regigigas’s flag fixed it. But I had not caught Regigigas prior.

---

That's so strange. I look forward to this question showing up in a "top 10 obscure glitches you didn't know about" video in ten years :P

---

I am very confident this is a glitch. It’s something completely unexplained that’s happened to multiple people at random with zero real explanation. It’s completely bazar resetting Regigigas’ flag fixed it… almost like the flag itself was the problem. I plan on running some tests on it in the future, with a new save file and playing with various flags. As soon as the source code is public, I plan on datamining it myself. I might be the one to post that video :P

It might be worthwhile to add, I did modify this safe file before Badge #1, but nothing that should impact this. I gave myself Surf, the Shiny Charm, and Pokeballs, as I wanted to make the challenge a bit more enjoyable. Nothing like that should impact the Regi Flags, and I highly doubt the countless other people with the same issue did the same thing.

I might have to update this post.
