You finally beat the Elite Four. You’ve sat through the credits. Now, you’re standing in Vaniville Town thinking, "Okay, where are the rest of them?" Honestly, the post-game hunt for pokemon xy mega stone locations is a bit of a grind if you don't know the specific rules the game forgets to tell you. It’s not just about walking to a patch of grass. It's about timing. It’s about a specific upgrade to your Mega Ring. If you aren't hunting between 8:00 PM and 8:59 PM, you’re basically wasting your time.
That one-hour window is everything.
The Anistar City Gatekeeper
Before you can even see the sparkles on the ground, you have to talk to Professor Sycamore. He’s hanging out by the sundial in Anistar City after you’ve completed at least one battle in the Kiloude City Battle Mansion. He touches your ring, gives it a little "spark," and suddenly, the world changes. But only at night. Specifically, the game uses your 3DS internal clock. If it’s 7:59 PM, the stones don't exist. If it’s 9:01 PM, they vanish. It’s a narrow, slightly annoying window that forced a lot of us back in 2013 to manually change our system settings, though doing that sometimes messes up daily events.
Why the Post-Game Hunt Matters
Mega Evolution changed the meta forever. It wasn't just a gimmick; it turned forgotten Pokémon like Mawile and Kangaskhan into absolute monsters. If you’re playing through Pokémon X or Pokémon Y today, you’re likely doing it to complete a Living Dex or just to experience the sheer power of Mega Mewtwo Y. Finding these stones is the difference between a standard playthrough and total dominance.
Tracking Down the Version Exclusives
This is where it gets tricky. Game Freak loves splitting content. If you have Pokémon X, you’re looking for different items than your friend with Pokémon Y.
Manectite vs. Houndoominite
Head to Route 16. There’s a spot where two skaters are circling a patch of flowers. If you’re playing X, you’ll find the Manectite here. If you’re on Y, it’s the Houndoominite. It’s tucked away near a boulder that requires Strength to move. Most people miss it because they’re rushing toward Dendemille Town.
Pinsirite and Heracronite
Santune Forest is usually a place you forget about thirty minutes into the game. Go back. In Pokémon X, the Pinsirite is hiding in the tall grass near the entrance. In Pokémon Y, you’ll find Heracronite. These two are arguably some of the best Mega Evolutions for a competitive run-through, especially Mega Pinsir with Aerilate.
The Tyranitarite and Aggronite Split
Cyllage City Gym is built into a cliffside. You need to go to the second floor of the gym itself. In Pokémon X, you’ll snag the Tyranitarite. In Pokémon Y, it’s the Aggronite. It’s weirdly tucked behind a rock formation that feels like it should be decorative.
The "Anytime" Stones
Not everything is locked behind the 8 PM rule. Some pokemon xy mega stone locations are accessible the moment you have the right HM or just enough cash.
Take the Lucarionite. You get it for free. Korrina basically hands it to you after your showdown at the Tower of Mastery. It’s the game's way of saying, "Here is the mechanic, please use it." Then there’s the Abomasite. After you rescue Abomasnow from Team Flare in Frost Cavern, just talk to him again. He gives it to you as a thank you. Simple.
But then there are the starters.
The Kanto Starters and the Stone Emporium
When you meet Sycamore in Lumiose City early on, he lets you pick a Kanto starter. He gives you the corresponding stone then. But what about the other two? You have to buy them.
There is a shop in Lumiose City called the Stone Emporium. It’s on Vernal Avenue. A man there sells the other two stones (Venusaurite, Charizardite, or Blastoisinite). The price is astronomical at first—literally a million Poké Dollars. Don't pay that. Your "Style" rank in Lumiose City lowers the price. If you’re famous enough (by doing jobs, eating at restaurants, and talking to everyone), the price drops to a measly 10,000 Poké Dollars. It’s a massive discount.

Hunting the Heavy Hitters: Mewtwonite and Beyond
Mewtwo is the crown jewel. Once you’ve entered the Hall of Fame, head to the Unknown Dungeon near Pokémon Village. You’ll have to catch Mewtwo first (good luck with that capture rate). Once he’s in the ball, you’ll automatically pick up either Mewtwonite X or Mewtwonite Y depending on your version.
Garchompite
This one is a pain. It’s on Victory Road. You need to head toward the end of the caves where there’s a small outdoor area with a tower. You have to use Rock Smash on a specific wall. It only glitters during that 8-9 PM window. If you haven't brought a "utility" Pokémon with Rock Smash, you’re trekking all the way back to the PC.
Alakazite
Reflection Cave is a maze. It’s beautiful, but a maze. Go to the lowest level (B3F). There’s a patch of light reflecting off a mirror on the back wall. You’ll see the sparkle in the reflection before you see it on the ground. It’s one of the cleverest uses of the game's 3D environment.
Gengarite
In Laverre City, there’s a black-haired woman standing near the northern part of town. Talk to her. She just gives it to you. No puzzles, no time limits. Just a gift for being a trainer. Mega Gengar is a "Ubers" tier threat, so this is arguably the most powerful freebie in the game.
Gardevoirite
Go to Café Soleil in Lumiose City after the credits. Diantha is there. She wants to trade you a Ralts. Take the trade. The Ralts is holding the Gardevoirite.

Why Some Stones Feel Impossible to Find
The issue with searching for pokemon xy mega stone locations is the verticality of Kalos. Areas like Route 17 (the snowy Mamoswine path) or the Magnum Opus Stadium feel huge but have very few hidden items. Meanwhile, a tiny corner in Courmarine City holds the Banettite.
You have to look for the "Purple Sparkle."
Regular items in Pokémon games are Poké Balls on the ground. Hidden items are found with the Itemfinder. Mega Stones are different. They appear as a bright, pulsating purple light. But again—and I cannot stress this enough—if your 3DS clock is wrong, they don't pulse. They don't exist.
The Mega Gyarados and Scizor Problem
Mega Gyarados is found in Couriway Town. You’ll see some waterfalls. Use Waterfall to climb them. The stone is just sitting there in the middle of a small pool.
Mega Scizor is more annoying. It’s in Frost Cavern, tucked behind the Abomasnow you rescued earlier. Because the area is so washed out and white with snow, the purple sparkle is actually harder to see than in the dark caves.
The "Style" Factor in Lumiose City
I mentioned this before, but it's worth a deeper look because it affects the Stone Emporium. If you are struggling to find the money for the starter stones, do these things:
- Visit the Museum.
- Work at Hotel Richissime.
- Take a Cab (even if you don't need to).
- Buy some cheap Premier Balls one by one at the Poke Ball Boutique.
Maxing out your style doesn't just lower prices; it unlocks more of the city. It’s a core part of the XY experience that feels like a chore but pays off when you’re trying to optimize your team.
Navigating the 8 PM Glitch/Feature
Some players try to "time travel" by changing their system clock to 8:00 PM. Be careful. If you change the time on your 3DS, the game often locks all "time-based events" for 24 hours as a penalty for cheating. If you change the clock and the stones aren't appearing, that's why. You might have to wait an actual day for the internal clock to resync. The best way to handle this is to set your clock to 7:55 PM, save your game, turn it off, and wait those five minutes for the game to naturally hit 8:00 PM.
Actionable Steps for your Kalos Post-Game
- Update the Ring First: You can’t find the hidden stones without the upgrade from Sycamore in Anistar City. This requires one Battle Mansion fight in Kiloude City.
- The 8 PM Sprint: Prepare a "Flying" Pokémon and a "Surfer" in your party before 8:00 PM. You only have sixty minutes. Map out your route. Start in Santune Forest, fly to Cyllage, then hitting Victory Road.
- Check Your Version: Don't spend twenty minutes looking for Tyranitarite in Pokémon Y. It’s not there. You’ll find Aggronite instead.
- Talk to Everyone: NPCs like the girl in Laverre City or Diantha in the cafe are the only ways to get Gengarite and Gardevoirite.
- Save Your Money: Don't buy the starter stones until you’ve grinded your Style rank. Paying 1,000,000 versus 10,000 is a no-brainer.
The Kalos region is massive. It’s easy to get lost in the transition between the 2D-style movement and the 3D camera angles. Just keep your eyes peeled for that purple glow and keep a close watch on the clock. Happy hunting.
