How to Catch Mew in Pokémon Infinite Fusion — Complete Guide

Mew is hiding in Pokémon Infinite Fusion, and yes — you can actually catch it. The pink Mythical Pokémon spawns as a rare overworld encounter in the Viridian River, a hidden area tucked behind the Secret Forest, but only if your Karma is high enough. Walk in with good Karma and listen carefully: a sparkling chime means Mew is waiting for you somewhere along the riverbank. Walk up, talk to it, and the battle begins.

This guide explains how to catch Mew in Pokémon Infinite Fusion step by step: the exact location, the Karma requirement most players miss, the best catching strategy with False Swipe and status conditions, Mew’s base stats, the best Mew fusions to try, and how it compares to Mewtwo.

Mew at a Glance

Before you go hunting, here is everything you need to know about Mew’s profile in Pokémon Infinite Fusion version 6.7.2:

• Type: Psychic
• Ability: Synchronize (passes burn, poison, or paralysis to the attacker)
• Base stats: 100 HP / 100 Attack / 100 Defense / 100 Sp. Attack / 100 Sp. Defense / 100 Speed — 600 total
• Catch rate: 45 — tough but very manageable with the right setup
• Gender: Genderless
• Evolutions: None — Mew does not evolve into or from anything
• Signature move: Transform — copies the target’s species, stats, and moves
• Held item in the wild: Lum Berry

Mew’s claim to fame is its perfectly balanced 600 base stat total — every single stat sits at 100, which makes it one of the most flexible Pokémon in the entire game. It can be built as a physical attacker, a special attacker, a bulky support, or anything in between. On top of that, Mew is famous across every Pokémon game for learning an enormous TM and tutor movepool, and Infinite Fusion keeps that tradition: Mew can learn far more moves than almost anything else in the game, which makes it an incredible fusion partner too.

Where to Find Mew in Pokémon Infinite Fusion

Mew spawns in the Viridian River, a secret area connected to the Hidden Forest (also called the Secret Forest) between Route 2 and Route 16 in Kanto. This is the same hidden spot where rare starter Pokémon appear as overworld encounters — but Mew only shows up under one special condition, which we will cover next.

Requirements to Reach the Viridian River

You cannot just walk in at the start of the game. Here is what you need first:

• At least 4 badges — the Secret Forest only opens up after you have made real progress through Kanto.
• Erika defeated — beating the Celadon City Gym Leader is the trigger that unlocks the Route 2 entrance.
• Cut and Surf — you need Cut to clear the plants blocking the path, and Surf to explore deeper into the Hidden Forest.
• Rock Climb (Route 2 entrance only) — a ledge on the Route 2 side requires Rock Climb to reach the river itself.
• High Karma — the big one. Mew only spawns if your Karma is good. More on this below.

The Two Entrances

There are two ways into the area. The Route 16 entrance is through the west exit of Celadon City, past the house of the man who gives you the Fly TM — use Cut on the blocking plants. The Route 2 entrance is on the Route 2 side before Viridian Forest, where you use Rock Climb on the ledge. Both entrances lead through the Hidden Forest into the Viridian River.

How Karma Works and Why It Matters

Karma is a hidden stat in Pokémon Infinite Fusion that tracks your good and evil deeds throughout the story. Doing kind things — completing side quests, helping NPCs, choosing the generous dialogue options — raises your Karma. Stealing, lying, and choosing selfish options lowers it. Most players never think about it, which is exactly why so many people walk through the Viridian River dozens of times and never see Mew.

Here is the rule, confirmed by the game’s own walkthrough: players with high Karma have a chance for a rare Mew encounter in the Viridian River, while players with low Karma get Darkrai on Newmoon Island instead. If your Karma is neutral or low, Mew simply will not spawn, no matter how many times you re-enter. That is why checking your Karma is step one.

How to Check and Fix Your Karma

• Travel to Ecruteak City and talk to the Karma lady — she will tell you whether your Karma is good, bad, or neutral.
• If your Karma is bad or too low, head to the Dragon’s Den and donate ₽5000 to the lady there to reset your Karma to zero.
• From zero, raise your Karma by doing good deeds: finish side quests, help NPCs in trouble, and pick the kind dialogue options whenever the game gives you a choice.
• Once the Karma lady confirms your Karma is good, head back to the Viridian River and start hunting.

How to Catch Mew in Pokémon Infinite Fusion: Step-by-Step

Once your Karma is good and you can reach the Viridian River, catching Mew is a simple loop. Here is the exact process:

Step 1 — Confirm Your Karma Is High

Talk to the Karma lady in Ecruteak City one more time before you start. This is the single most common reason people fail to find Mew — everything else can be perfect, but low Karma means zero chance of a spawn. Do not skip this check.

Step 2 — Enter the Viridian River Through the Hidden Forest

Fly or walk to either the Route 16 or Route 2 entrance and make your way into the Viridian River. The moment you walk in, stop and listen. The game plays an audio cue when overworld encounters spawn: a fleeing footsteps sound means starter Pokémon have appeared, but a special sparkling, glistening chime means Mew is present. Turn your volume up — this sound is your entire hunting strategy.

Step 3 — If You Hear the Chime, Search the Map

When you hear the sparkling sound, Mew has spawned somewhere on the map. Walk the riverbanks carefully and look for it — like the starter overworld encounters, Mew appears as a visible sprite you walk up to and talk to, not a random grass encounter. Check around the small islands and the edges of the water. If you entered through one of the warp tiles from the Hidden Forest, note that each tile spawns a different set of encounters, so try entering through the other tile if you keep missing it.

Step 4 — No Chime? Leave and Re-Enter

Mew is rare, so most entries will only spawn starters. That is completely normal. Walk out of the Viridian River back into the Hidden Forest, then walk back in and listen again. Each entry re-rolls the spawns. Repeat this loop patiently — it may take a while, but the chime will eventually play. Bring something to do between attempts, because this is the grindy part of the hunt.

Step 5 — Save Before You Talk to Mew

When you finally spot Mew, save your game first. Overworld legendary encounters in Infinite Fusion are one-shot opportunities — if you knock it out or it flees, you may have to grind the spawn loop all over again. Saving takes two seconds and removes all the risk from the battle.

Step 6 — Start the Battle and Catch It

Talk to Mew to start the encounter. Mew spawns at a modest level, roughly in the same low range as the other overworld spawns in the area, so it is not the hardest legendary fight in the game — the challenge is finding it, not beating it. Use the catching strategy in the next section and you will have it in your party within a few minutes.

The Best Catching Strategy for Mew

Mew has a catch rate of 45, which puts it in the same difficulty bracket as most legendaries — not the brutal 3 of the box legendaries, but tough enough that chucking Ultra Balls at full health is a waste of money. The good news is that Mew spawns at a low level in the Viridian River, so the actual battle is short. Here is the team and item setup that makes the catch nearly guaranteed:

Bring a False Swipe Pokémon

False Swipe always leaves the target with at least 1 HP, so you can attack Mew freely without any risk of knocking it out. Great False Swipe users you can get early include Scyther, Parasect, and Zangoose — or fuse one of them for better bulk. Open with False Swipe until Mew is sitting at 1 HP, then start throwing balls.

Add a Status Condition

Sleep and paralysis multiply your catch odds dramatically. Spore (from Parasect or a fused Breloom) is the gold standard because it never misses, but Thunder Wave or a fast Yawn user works too. One warning: Mew’s Synchronize ability passes burn, poison, or paralysis back to your Pokémon, so bring a status healer or a sacrificial status applier you do not mind getting paralyzed.

Stock Up on Balls

• Ultra Balls — your main tool. Bring 20-30 to be safe.
• Timer Balls — excellent if the battle drags on; they get stronger every 10 turns.
• Dusk Balls — worth trying if you are hunting at night in-game.
• Quick Balls — throw one on turn one; occasionally you get lucky immediately.

At 1 HP with sleep or paralysis, Ultra Balls will usually land Mew within a handful of throws. If you run out of balls mid-battle, do not panic — just reset to your save from Step 5 and try again with a bigger stock.

Mew’s Base Stats and What Makes It Good

Mew’s 100-across-the-board stat spread gives it a 600 base stat total — the same territory as the strongest non-legendary fully evolved Pokémon, but with perfect balance instead of specialization. Here is why that matters in Infinite Fusion:

• Unmatched flexibility: 100 Attack and 100 Sp. Attack mean Mew can run physical, special, or mixed sets equally well. Most Pokémon force you to pick one.
• Real bulk: 100 HP, 100 Defense, and 100 Sp. Defense let Mew take hits while it sets up with moves like Swords Dance, Nasty Plot, or Calm Mind.
• Great speed tier: 100 Speed outruns most of the mid-game and a lot of the post-game, especially after a setup boost.
• Massive movepool: Mew learns Transform naturally and can be taught an enormous range of TMs, making it the ultimate toolbox Pokémon.
• Perfect fusion DNA: because every stat is exactly 100, Mew passes clean, predictable stat boosts into any fusion without lopsided weaknesses.

The one real downside is typing: pure Psychic is weak to Bug, Ghost, and Dark, and Infinite Fusion’s late game is full of all three. That is exactly why most players fuse Mew rather than running it unfused — a good fusion partner fixes the typing while keeping Mew’s incredible stat base.

Best Mew Fusions in Pokémon Infinite Fusion

Fusing is where Mew truly shines. Its balanced 100s make it one of the most forgiving fusion partners in the game — almost any strong body or head you pair it with gets a clean upgrade. Here are the fusion directions players love most:

• Mew + Mewtwo: the dream pairing — Mew’s balance meets Mewtwo’s 154 Sp. Attack glass-cannon DNA for a Psychic-type monster that hits like a truck and actually survives a hit back.
• Mew + Gengar: adds Ghost typing and a terrifying special attacking presence; the Speed and coverage combination is one of the scariest in the game.
• Mew + Dragonite: Dragon/Flying or Dragon/Psychic bulk with Multiscale-style survivability and Mew’s perfect 100s smoothing out every stat.
• Mew + Tyranitar: Dark typing patches Mew’s Ghost and Dark weaknesses while Sand Stream chip damage and huge Attack make it a physical wrecking ball.
• Mew + Alakazam: doubles down on Psychic with absurd Speed and special power — fragile, but almost nothing outspeeds it.
• Mew + Snorlax: turns Mew into an immovable special wall with 100 Attack backing up Body Slam and Earthquake.

Before you commit your DNA splicers, test the exact stat spreads and type combinations on our Pokémon fusion tool or the fusion calculator — seeing the real numbers first saves you from fusing something you regret. And if you want a full breakdown of how fusion mechanics work, our fusion guide walks through DNA splicers, reversed fusions, and triple fusions in detail.

Mew vs Mewtwo: Which Should You Hunt?

Every player asks this eventually. Mew and Mewtwo are the two Psychic-type legendaries of Kanto, and they could not be more different in practice:

• Mewtwo is the specialist: 680 base stats with a monstrous 154 Sp. Attack and 130 Speed. It is the strongest special attacker you can catch in the main storyline, found at the bottom of Cerulean Cave. If you want raw damage, Mewtwo wins every time.
• Mew is the generalist: 600 base stats, perfectly balanced, with a far bigger movepool and much better fusion flexibility. It is easier to fit on any team and easier to build around.
• Availability: Mew is available far earlier (mid-Kanto, once you have 4 badges and good Karma), while Mewtwo is a post-game-style challenge deep in Cerulean Cave.

The honest answer: hunt both. Mew carries your mid-game and becomes elite fusion material, and Mewtwo anchors your endgame team. They even fuse beautifully together. If you only have time for one hunt right now, go for Mew first — it is available earlier and useful sooner.

How to Use Mew on Your Team

Once Mew is yours, it slots into almost any team archetype. Here are the most effective roles:

• Setup sweeper: Swords Dance or Nasty Plot + Mew’s 100 Speed + great coverage = a win condition against most story bosses.
• Utility support: Mew’s huge movepool includes Stealth Rock, Thunder Wave, Will-O-Wisp, and U-turn — it can be your team’s glue.
• Transform scout: Transform copies the opponent’s stats and moves, which is hilarious and occasionally brilliant against setup sweepers.
• Fusion donor: honestly, most competitive Infinite Fusion players fuse Mew rather than running it raw — those perfect 100s are wasted on a pure Psychic typing when a partner could fix its weaknesses.

Can You Get Shiny Mew?

Yes — shiny Mew is possible in Pokémon Infinite Fusion. Because Mew is an overworld spawn, you can save right in front of it and soft-reset until it shines, which is far more comfortable than full-odds random encounters. The shiny odds follow the game’s normal shiny rate, so expect a long grind. One tip: do your shiny hunt during the same Karma-checked session where Mew spawns, and make a separate save the moment you see the sparkle animation so you never lose the shiny to a misclick.

Frequently Asked Questions

Where is Mew in Pokémon Infinite Fusion?

Mew spawns as a rare overworld encounter in the Viridian River, a hidden area behind the Secret Forest between Route 2 and Route 16. You need good Karma for it to appear at all.

Why can’t I find Mew in the Viridian River?

Almost always, the answer is Karma. Mew only spawns for players with high Karma — check with the Karma lady in Ecruteak City. If your Karma is low, reset it with a ₽5000 donation at the Dragon’s Den and then raise it with good deeds. Also make sure you are listening for the sparkling chime when you enter; without the chime, Mew did not spawn that time.

What level is Mew when you catch it?

Mew spawns at a modest level, roughly in the same low range as the other overworld encounters in the Viridian River — this is a hunt about patience and Karma, not about surviving a level 70 boss fight. Bring a False Swipe user around that level range so you can weaken it safely.

Can you fuse Mew with other Pokémon?

Yes. Mew can be fused using DNA splicers like any other Pokémon, and its perfectly balanced 100 base stats make it one of the best fusion donors in the game. Preview your combinations on the fusion calculator first.

Is Mew better than Mewtwo?

Not in raw power — Mewtwo’s 680 stats and 154 Sp. Attack make it the stronger pure attacker. But Mew is more flexible, has a bigger movepool, is available much earlier, and is the better fusion partner. Most players want both.

Does Mew respawn if I knock it out?

Treat the encounter as one-shot: save before you talk to Mew. If you knock it out, you will likely need to grind the re-enter loop until it spawns again — and some legendary encounters only respawn after beating the League, so do not risk it. Save first, always.

What is the fastest way to get high Karma?

Complete side quests, help NPCs, and choose kind dialogue options. If your Karma is deep in the negative, donate ₽5000 at the Dragon’s Den to reset to zero first, then build it back up with good deeds rather than digging out of a hole.

Conclusion

To catch Mew in Pokémon Infinite Fusion: get 4 badges, beat Erika, raise your Karma high, enter the Viridian River through the Hidden Forest, listen for the sparkling chime, save before engaging, and catch it with False Swipe, sleep, and Ultra Balls. Good luck, trainer — the pink Mythical is worth the grind.
