You’re standing in the middle of Route 2, staring at a patch of grass, and you realize something annoying. You need a rare spawn, but the RNG just isn't cooperating today. It’s frustrating. Honestly, the grind in Alola can feel like a slog if you're trying to do everything the "natural" way. But there's this weird, semi-forgotten mechanic built right into your Rotom Dex that basically bypasses the headache. I'm talking about the QR Pokemon Ultra Moon scanner. It’s not just some gimmick Nintendo threw in to sell toys; it’s a legitimate shortcut for finding monsters that shouldn't even be in the game.
Most people used it once or twice back in 2017 and then just... stopped. That’s a mistake. If you’re dusting off your 3DS or running a fresh playthrough on an emulator, you’ve got to leverage the Island Scan.
How the QR Pokemon Ultra Moon System Actually Works
The scanner is basically a point-accumulation game. You open your menu, hit the QR Scanner option, and start blasting codes. You can find these codes on the back of Magearna promotional flyers, the old Pokemon TCG cards, or just by searching for "QR Pokemon Ultra Moon" databases online. Every scan gives you 10 points. Once you hit 100 points, you unlock the Island Scan.
It's simple.
But here is the kicker: the Pokemon you find via Island Scan are often from other regions. We're talking Johto starters, Sinnoh classics, and heavy hitters like Honchkrough or Aegislash. You only get one shot at the encounter once the scan triggers, so if you accidentally knock it out or run away, you've gotta wait for your scanner to recharge. It recharges at a rate of one scan every two hours. It's slow.
The Magearna Secret
If you haven't done this yet, you're missing out on a free Mythical. Usually, Mythicals are locked behind expired "Mystery Gift" events that ended years ago. Not Magearna. Because the QR code for Magearna was baked into the game's marketing as a permanent fixture, you can still scan it today in 2026.
- Beat the main story (become Champion).
- Go to the QR Scanner.
- Scan the special Magearna code (easily found on the official Pokemon website archives).
- Head over to the Antiquities of the Ages shop in Hau'oli City.
- Talk to the delivery man.
Boom. Level 50 Magearna with a Bottle Cap. It’s probably the easiest Mythical to get in the entire franchise history, excluding maybe the Manaphy egg in the Diamond/Pearl remakes.

Why Island Scan Patterns Matter More Than You Think
You can't just scan and hope for the best. The game operates on a strict weekly schedule. If you use your QR Pokemon Ultra Moon points on a Tuesday on Melemele Island, you are going to get a Luxio. Every single time. If you do it on a Saturday, you get Litwick.
This predictability is your best friend.
Let's say you're building a competitive-ish team for the Battle Tree. You need a Serperior with Contrary. You could try trading for one, or you could just wait until Thursday, fly to Poni Island, and trigger your Island Scan. Serperior will just show up in the wild at Exeggutor Island. It saves you so much time.
The variety is wild. On Poni Island alone, you can snag Eelektross (Sunday), Aggron (Monday), Rotom (Tuesday), Leavanny (Wednesday), Serperior (Thursday), Samurott (Friday), and Emboar (Saturday). It's basically a buffet of non-Alolan species.
Understanding the Scanner Limitations
It isn't a magic "win" button. There are a few things that trip people up. First, scanning a regular QR code for a Pokemon you haven't seen yet will add it to your Pokedex as "seen." This is great for checking habitat locations. However, it doesn't count as "caught." You still have to go find the thing.
Secondly, the "Special" QR codes—like the ones from the Pokemon Ga-Olé discs in Japan—give you 20 points instead of 10. If you can find those online, you can trigger your Island Scan twice as fast.

Maximizing Your Daily Scans
A lot of players think they can only scan Pokemon-related codes. That's a myth. The Rotom Dex is surprisingly dumb; it will try to read almost any QR code you shove in front of its face. Bored at breakfast? Scan the QR code on your cereal box. It'll probably give you 10 points and register a random Pokemon entry.
I’ve seen people scan their Wi-Fi router passwords or Spotify codes just to fill the meter. It works. The game just generates a random data string and maps it to a Pokemon in the database.
The Competitive Edge: Egg Moves and Hidden Stats
One thing the hardcore community loves about the QR Pokemon Ultra Moon Island Scan is the move sets. Pokemon caught via Island Scan often come with a "special" move that they wouldn't normally have at that level. While they don't usually have Hidden Abilities—which is a major bummer—they provide a great "parent" for breeding.
For instance, if you catch a Charmander on Melemele Island (Sunday), it might have an egg move already tucked into its kit. This cuts out three steps of the breeding chain.
Rare Spawns You Should Target Immediately
If you're looking for the absolute best value for your 100 points, focus on these:
- Honedge (Akala Island, Wednesday): Aegislash is a beast. Getting a Honedge early in the game trivializes many of the Totem fights.
- Deino (Poni Island, Tuesday): Hydreigon is a late-game monster, but getting a Deino via scan is much more reliable than hoping for rare ripples in the water or cave shadows.
- Starters: Look, everyone loves the starters. Being able to catch Decidueye's counterparts from Kanto, Johto, and Unova without trading is a huge plus for solo players.
How to Get the Most Out of Your Scanner Experience
Don't just scan blindly. Prepare.

Make sure you have a "Catcher" Pokemon ready. A Smeargle or Gallade with False Swipe and a status move like Spore or Thunder Wave is mandatory. Remember, you only get one encounter per 100 points. If that Aggron uses Roar or your game crashes, those points are gone, and you're waiting hours for a recharge.
Also, check your island. If you trigger the scan while standing on Melemele, but the Pokemon you want is on Ula'ula, you've wasted your scan. The scan is specific to the island you are physically standing on when you hit the button.
Step-by-Step for Maximum Efficiency:
- Gather your codes: Find a collage of 10 QR codes online. Keep them open on your phone or laptop.
- Save your game: Do this before you trigger the 100-point Island Scan.
- Check the Day: Ensure the real-world day matches the Pokemon you want (e.g., Friday for Samurott on Poni).
- Travel: Fly to the correct island.
- Trigger: Run the scan and check the radar for the exact patch of grass or cave.
- Catch: Use a Quick Ball immediately. If that fails, switch to False Swipe.
The QR Pokemon Ultra Moon feature is a relic of a time when Nintendo was experimenting with "cross-media" interaction, but it remains one of the most functional parts of the Gen 7 experience. It turns the 3DS camera into a literal portal for Pokedex completion.
Next time you’re stuck trying to find a rare encounter, stop running in circles. Just scan. It’s faster, it’s guaranteed, and it lets you play with favorites that the Alolan climate usually wouldn't support.
To get started right now, locate a reliable 2D code database—often hosted on sites like Imgur or dedicated Pokemon fan wikis—and scan your first 10 codes to see what's lurking on your current island. Keep a calendar of the weekly rotations handy so you never waste a 100-point charge on a Pokemon you already own. Focus on catching the Poni Island scans first, as they represent the highest-level encounters and most powerful evolutionary lines available through the system.
