How to Complete the Pokédex in Pokémon Infinite Fusion: 501 Catches, the Magic Boots, and Debug Mode

Completing the Pokédex in Pokémon Infinite Fusion means catching all 501 base Pokémon, and the reward is unlike anything in the official games: the Magic Boots, which unlock full Debug Mode. There is no Shiny Charm for finishing the dex here (that comes from the post-game instead), no diploma, and no pat on the back. Just a quiet Game Developer sitting in a Celadon City condominium, waiting to hand the most powerful item in the game to anyone patient enough to catch them all.

This guide covers exactly what counts toward completion, clears up the outdated numbers still floating around old guides (351 and 420 are both wrong now), and lays out a practical catching strategy so you are not wandering Kanto at hour 200 with 40 entries missing. Everything below is current for version 6.7.2.

What completing the Pokédex actually means here

The game’s Pokédex tracks 501 base Pokémon: the full Kanto and Johto rosters plus the new additions the developers have added over the years. Fusions do not count. You could fuse every species in the game into ten thousand hybrids and your completion percentage would not move. The check the Game Developer runs is simple: have you caught one of each of the 501 base species?

Caught matters. Entries you have only seen, the silhouettes that fill in when a trainer uses a Pokémon you do not own yet, do not count toward the reward. The Pokémon must be registered as caught, which happens when you capture it, receive it in a trade, hatch it from an egg, or evolve into it. Evolving a Pokémon you already own registers its evolution, so a full evolution line usually only requires catching the base form and leveling it up, not catching each stage separately.

There is one more condition that trips people up: the completion must happen in a non-randomized mode. If you played through on a randomized seed, the Game Developer will not hand over the Magic Boots no matter how full your dex looks. If you want this reward, do your completion run on a normal save.

You can check your progress any time from the Pokédex menu itself. The game shows how many species you have caught, so you always know exactly how far you are from 501. When that number reads 501, head to Celadon City.

The reward: Magic Boots and full Debug Mode

The Magic Boots are Infinite Fusion’s version of a completion reward, and they are far more generous than the official games’ Shiny Charm. Equipping them and pressing F9 opens the Debug Menu: a full developer console that lets you add any item to your inventory, set your money, heal your party, warp to any map, toggle the Pokédex, reset trainers, hatch eggs instantly, and edit variables. It is the same toolkit the developers use to test the game, handed to you as a trophy.

Talking to the Debug Fish NPC after obtaining the boots takes you to Testing Island (also called Debug Island in some guides), where NPCs can generate specific Pokémon fusions for you, create single or double battles on demand, teach or erase moves, adjust friendship, and back up your save. For players who love experimenting with fusion builds on the team builder page and then want to try them in-game, this is the fastest possible route from theory to battle.

One warning before you start pressing buttons in the Debug Menu: back up your save first. The game stores saves separately from the game folder, so copy your Game.rxdata file somewhere safe. Debug tools can warp you into unfinished maps and flip story switches in ways that are hard to undo. The official Infinite Fusion walkthrough on the Fandom wiki lists the Pokédex Completion reward in its post-game section, and the community cheats guide at pokemoninfinitefusion.app walks through the same unlock with the current 501 figure.

Clearing up the confusing numbers: 351 vs 420 vs 501

If you search for how to complete the Pokédex in Pokémon Infinite Fusion, you will find three different numbers, and only one is right. Guides from 2023 say 420. Even older ones say 351 in Classic Mode. The current figure, confirmed by the Fandom wiki’s walkthrough and recent community guides, is 501 base Pokémon.

The number grew because the developers kept adding species. The wiki’s own walkthrough still carries an old note from August 2023 saying staff had announced new Pokémon and the total would “most likely rise,” expecting around 440 to 450. It rose past that. The takeaway: if a guide quotes 351 or 420, it was written for an old version and its strategy advice may be stale too. Aim for 501 in version 6.7.2, and if the developers add more species in a future update, expect the requirement to move with the roster.

Planning your completion run before you start catching

Completion is a marathon, so treat it like one. The players who finish fastest are not the ones who grind hardest; they are the ones who never catch the same Pokémon twice by accident and never realize at the end that something was missable. A little planning at the start saves dozens of hours later.

Catch with intent from the first route

Start catching everything the moment you get Poké Balls. It is tempting to run from weak early-route Pokémon, but every Rattata and Pidgey you skip is a detour you will have to make later, when those routes feel like a chore. Keep one of each species as you go. Your PC boxes are effectively your progress bar.

Work region by region, not randomly

Clear each area’s encounters before moving on. When you finish a route, open the Pokédex and check which species from that area are still missing, then go back and fill the gaps while you are still nearby. Players who bounce between regions end up with a scattered dex full of holes that take forever to audit later. The in-game dex shows encounter locations for species you have seen, which turns each missing entry into a short errand instead of a mystery.

Keep a living checklist

The game’s counter tells you the total, but it does not tell you which species are missing. Many completionists keep a simple spreadsheet of the 501 species and tick them off as they catch them, often sorted by route or by evolution family. The Infinite Fusion dex page on this site is a handy reference while you work through families, since you can look up typings and evolution lines without leaving the browser.

Catching methods that save you dozens of hours

You do not need 501 individual capture battles if you use the game’s systems well. These methods turn the grind from hundreds of encounters into a manageable project.

Evolve instead of re-catching

Catch the base form, then evolve it. One Abra becomes Kadabra and then Alakazam with no extra catching. This is the single biggest time saver in the whole run, because roughly two-thirds of the dex is evolutions of things you already caught. Level grinding is faster than hunting: use the Rare Candy farming methods from our farming guide and the trainers who rebattle, and whole evolution lines complete in an afternoon. Trade evolutions need a trade partner or the in-game trading systems, so flag those early (Kadabra, Machoke, Graveler, Haunter and their Johto counterparts) instead of discovering the requirement at 490 out of 501.

Breed the babies and the starters

Baby Pokémon like Pichu, Cleffa, and Togepi come from eggs, and the Day Care is the reliable way to produce them. You only get one shot at some starters and gift Pokémon, so breeding extras is how you fill related entries without replaying the game. Our egg hatching guide covers how to speed the process up, which matters when you need a dozen eggs for baby and branching-evolution entries.

Bring the right catcher

A dedicated catching Pokémon with False Swipe and a sleep or paralysis move pays for itself within the first region. False Swipe guarantees the target survives at 1 HP, and sleep roughly doubles your catch odds compared to a awake target at full health. Stock Ultra Balls before long hunting sessions, and keep a few dozen on hand at all times once you reach the mid-game; running out mid-route is how sessions die. The Master Ball guide on this site covers where the game’s guaranteed catches come from, worth saving for the entries that only appear once.

Use NPC trades and static encounters

Several species are easier (or only) obtained through in-game trades and static gift encounters rather than wild grass. Talk to every NPC; traders often ask for common Pokémon and hand over species that are rare or version-limited in the wild. Static encounters, the Pokémon waiting in fixed spots rather than random grass, do not respawn if you knock them out, so save before those fights. If a static encounter faints, that entry may be locked until you can trade for it or breed it.

The hard entries: legendaries, one-time encounters, and version quirks

The last 30 entries are always the slowest, and they are almost always the same categories. Knowing them in advance keeps the endgame from stalling.

Legendaries. The legendary birds, beasts, and other one-per-game encounters each need their own trip, their own strategy, and usually a Master Ball or a long False Swipe stall. Our legendary locations guide maps where every legendary waits, which is the natural companion piece to this guide once your dex is mostly full and the gaps are all glowing entries.

Fishing and special encounter methods. Some species only appear on a fishing rod, in headbutt trees, or in other special encounter tables. If your dex shows a gap for a species you have never even seen, check whether it needs a rod or a special method rather than more grass encounters. The in-game dex’s area data points you to the right method once you have seen the species at least once, which is another reason to fight every trainer: their Pokémon fill in “seen” data that guides your later hunting.

Version updates. The roster grew from 351 to 420 to 501 across updates, and older saves carried forward can have strange gaps. If you started your save on an old version and updated to 6.7.2, audit the newly added species specifically; they are the ones most likely to be missing. Our download page always points to the current version, and updating before a completion run avoids the worst of the version-gap problem.

Claiming the Magic Boots step by step

When the dex counter reads 501 caught, the reward is a short trip, not a quest. Here is the exact sequence:

• Confirm 501 caught in the Pokédex menu, on a non-randomized save, in version 6.7.2.
• Fly or travel to Celadon City in Kanto.
• Find the condominiums (the residential building) and go inside. One of the rooms houses the Game Developer NPC.
• Talk to the Game Developer. He checks your dex, and with all 501 base Pokémon caught, he hands over the Magic Boots.
• Equip the boots and press F9 to open the Debug Menu for the first time.
• Back up your save before experimenting, then talk to the Debug Fish NPC to visit Testing Island.

While you are in that condominium, check the laptop in front of the developer’s room. It displays an email that is a Cease & Desist letter from a large videogame company, one of the game’s best-known jokes and a nod to its fan-game status. The Fandom wiki’s Secrets and Easter eggs page documents it alongside the other hidden gags.

What Debug Mode actually gives you

The Debug Menu is extensive. Community documentation of the F9 menu lists these capabilities: add any item, edit animations, open a debug console, heal the party, view map connections, quick-hatch eggs, refresh the map, reset trainers, set badges, set metadata, set money, change the player character, set terrain tags, flip switches, toggle the Pokédex, toggle running shoes, use the PC, edit variables, and warp to any map. Testing Island adds NPCs that generate specific fusions, run custom battles, adjust friendship, and manage save backups.

Used responsibly, it is a sandbox for the game’s best feature: fusion experimentation. Want to test whether a fusion concept from the fusion calculator actually performs? Spawn it, build a team around it on Testing Island, and battle. That loop, from idea to in-game test in minutes, is the real prize behind the 501-catch wall, and it is why completionists call the Magic Boots the best reward in any Pokémon game, official or fan-made.

Frequently asked questions

Do fused Pokémon count toward the 501?

No. Only the 501 base species count. Fusions have their own dex entries but do not move the completion counter the Game Developer checks.

Do I need to catch them, or is seeing them enough?

You need to catch them. “Seen” entries fill in the dex display but do not count toward the Magic Boots requirement.

Does a randomized playthrough count?

No. The 501 must be caught in a non-randomized mode. Plan your completion run on a normal save.

Is it 351, 420, or 501?

501 is the current number for version 6.7.2. The 351 and 420 figures come from older versions of the game, when the roster was smaller. Old guides quoting those numbers are outdated.

Do I get the Shiny Charm for completing the Pokédex?

No, and this is the most common mix-up. In Infinite Fusion the Shiny Charm is the reward for finishing the Mt. Silver post-game, not the dex. The dex reward is the Magic Boots. Our Shiny Charm guide covers that hunt separately.

Can I still complete the dex after the developers add new Pokémon?

The requirement tracks the current roster, so if new species are added, the target moves. The developers have expanded the dex before (351 to 420 to 501), so keep your game updated and expect the number to grow again someday.

Is completing the Pokédex in Pokémon Infinite Fusion worth it?

For most players, the honest answer depends on what you want. If you love the hunt itself, the 501-catch road is one of the longest and most satisfying completion challenges in any fan game, and it forces you to see corners of Kanto and Johto you would otherwise never visit. If you mainly want the reward, know what you are signing up for: dozens of hours of systematic catching for the most powerful sandbox tool the game offers.

Either way, start early, evolve instead of re-catching, breed the babies, save before every static encounter, and keep that checklist current. When the counter hits 501, the Game Developer in Celadon City is waiting, and Debug Mode is the best possible way to celebrate catching them all in Pokémon Infinite Fusion.
