You've spent hours grinding through the Borrius region. You’ve beaten the Elite Four, dealt with the shadows, and probably think you’ve seen everything this massive ROM hack has to offer. You haven't. Honestly, most players barely scratch the surface of the Pokemon Unbound mysterious creatures that populate the post-game. Skeli and the dev team didn't just throw in some standard legendaries and call it a day; they built a complex, often frustrating, series of triggers that make finding these things a genuine chore if you don't know where to look.
It’s easy to get lost.
The world is dense. Between the mission logs and the cryptic NPC dialogue, there is a lot of noise. But the "Mysterious Creatures" mission is the real deal. It’s the gateway to the heavy hitters. We’re talking about the bridge between being a champion and being a completionist.
What’s Actually Happening with the Mysterious Creatures Mission?
After you've secured your spot in the Hall of Fame, you need to head to the Pokémon Lab in Frozen Heights. You’ll talk to Log, and he basically dumps the "Mysterious Creatures" mission on you. It sounds simple. It isn't. This mission is the umbrella for tracking down the legendary beasts of Johto—Raikou, Entei, and Suicune.
Unlike the official games where these three might just wander aimlessly, Unbound ties them to specific world interactions. You can't just run through tall grass in Route 1 and hope for the best. Well, you can, but you'll be there forever.
The game forces you to actually use your brain. Or at least your DexNav.
First, you have to find them in their "static" locations to trigger the roaming. This is where people get tripped up. They expect them to be roaming from the jump. Nope. You’ve got to go to the places where they’ve been spotted. For instance, Raikou is chilling near the top of Thundercap Mountain, but only if the weather conditions and your mission progress align perfectly.
The Roaming Nightmare and How to Stop It
Roaming Pokémon are objectively annoying. We all know this. You fly to a city, they move. You walk through a gate, they move. In Pokemon Unbound, the mysterious creatures follow these same old-school rules, but with a modern twist.
If you're hunting Entei, Suicune, or Raikou, stop flying. Seriously. Flying resets their position entirely, often sending them to the opposite side of the map. Instead, find a route with a "gate" house (like the one between Route 9 and 10). Walk back and forth through the door. Check your map or DexNav. Eventually, the icon will overlap with your location.
Pro tip: Use a Pokémon with the Ability "Arena Trap" or "Shadow Tag." If you don't have a Wobbuffet or a Dugtrio, at least bring someone who knows Mean Look. If you let them flee once, you’re back to the gate-house grind. It’s tedious. It’s painful. But catching a 5-IV Raikou with a Timid nature makes it worth the headache.
Why Does Everyone Struggle with Suicune?
Suicune is the one that generates the most frantic Discord messages. It’s usually found near water—shocker—specifically around the Victory Road entrance or the Great Desert oasis areas depending on your save's specific RNG state. If you aren't seeing it, check your mission log. If "Mysterious Creatures" isn't active, Suicune basically doesn't exist.
Beyond the Johto Trio: The Real Enigmas
While the Johto beasts are the official "Mysterious Creatures," the term usually gets tossed around for anything that doesn't show up on a standard encounter table. We need to talk about the Portal Purge.
Once you get the Hoopa portals popping up, the game changes. This isn't just about walking in grass anymore. You're looking for literal rifts in spacetime.
- Palkia and Dialga: You’ll find these rifts at the top of Spear Pillar (Crystal Peak). But you need the Adamant and Lustrous Orbs. Without the items, the portals stay dormant.
- Regigigas: You need the other three Titans in your party. Standard stuff, right? But in Unbound, the Braille puzzles are actually integrated into the environment in a way that feels less like a gimmick and more like a tomb raid.
The complexity here is what makes Unbound better than most official titles. It doesn't hold your hand. If you want the "Mysterious Creatures," you have to earn them through side quests that actually have narrative weight.
The Mission "Antidote to a Curable Poison"
This is a weird one that connects back to the lore of rare encounters. You’ll meet a researcher who’s obsessed with Nigiruzame (a fan-made or modified form in some versions, but usually manifesting as a specific legendary encounter trigger in the 2.0+ builds). These missions often overlap. You might be hunting a "Mysterious Creature" and stumble into a completely different legendary questline.
Keep your items organized. The number of players who sell off a "weird stone" only to realize it was the trigger for a Lake Guardian encounter is staggering.
Specific Locations You Need to Bookmark
If you are tired of wandering, go to these spots once the post-game kicks off.
Thundercap Mountain. This is the heart of the electrical disturbances. Not just for Raikou, but for Zapdos and even certain Ultra Beasts later on. The magnetism here is a mechanical trigger. If you have a Pokémon with "Static" in the lead, your encounter rate for "mysterious" signatures increases significantly.
The Rift Cave. It’s exactly what it sounds like. If you're looking for things that shouldn't be in Borrius, they're probably hiding in the distortions here.
Victory Road. Don't just rush through it to get to the Elite Four. There are side chambers that only open after you’ve received certain National Dex flags. These chambers house the heavy hitters.

Fact-Checking the Myths
Let's clear some stuff up because the internet is full of bad info.
- You cannot catch Arceus before finishing the "New World" mission. Don't try. It won't happen. The portal won't even trigger.
- Shiny hunting roaming Pokémon is possible, but the stats and shininess are locked once they appear in the overworld. If you want a shiny Entei, you have to save before you trigger the initial encounter at its static spawn. If you save after it starts roaming, it’ll be the same Entei every time you see it.
- The DexNav is your best friend. If a Pokémon is "Unknown" but you've seen it in a portal, the DexNav can still track it if you have at least one "seen" entry.
Handling the Difficulty Curve
Unbound is hard. If you’re playing on "Expert" or "Insane," catching these creatures isn't just about throwing Ultra Balls. They will wipe your team. Mewtwo in the post-game is a genuine boss fight with aura buffs. You need a strategy that involves more than just "get it to 1 HP."
Status effects are non-negotiable. Sleep is better than paralysis because it prevents the Pokémon from using self-destructing moves or healing (looking at you, Lugia).
Also, get yourself a "Catching Smeargle."
- Move 1: False Swipe
- Move 2: Spore
- Move 3: Soak (to hit Ghost types with False Swipe)
- Move 4: Taunt (to stop them from Roaring you away)
Without this specific setup, you are going to waste hundreds of thousands of PokeDollars on balls that just won't click.
Your Immediate To-Do List
Stop flying around aimlessly. It’s the biggest mistake people make. If you want to wrap up the Pokemon Unbound mysterious creatures questline and finally fill that National Dex, follow these steps right now.
Go to Frozen Heights and confirm the mission is active in your Log. If it isn't, talk to every NPC in the lab. Once it's active, check the TV in any house. Often, the news reports will give you a "Sector" where a "strange golden beast" or "shining blue creature" was spotted. This isn't flavor text; it actually updates the roaming location.
Head to Thundercap Mountain first. It’s the most common trigger point for the Johto trio's initial flags. While you're there, make sure you have a Pokémon with Rock Climb and Strength. Half the portals are hidden behind environmental puzzles that require the ADM (Advanced Data Machine).
Grab the ADM from Captain Log after doing a few of his initial tasks. This item replaces HMs and is mandatory for reaching the deep-water or high-altitude spots where the rarest creatures hide.
Most importantly, keep an eye on the clock. Some of these creatures are time-sensitive. You won't find a "shadowy bird" (Darkrai or similar) at high noon. The internal clock of your emulator or device matters. If your RTC (Real Time Clock) isn't working, half of these events will never trigger. Check your emulator settings before you spend three hours looking for a Pokémon that only spawns at 3:00 AM.
Get your Smeargle ready, stop using Fly, and start cycling through the gates. The Borrius legendaries aren't going to catch themselves, and the "Mysterious Creatures" mission is the only way to prove you've actually mastered this game.
