So, you’re looking at your Game Boy Advance or maybe a dusty DS Lite and thinking about finishing it. The big one. Catching Pokémon Fire Red all Pokémon is a task that sounds simple until you actually start looking at the data. It's not just about walking through tall grass. Honestly, it’s a logistical nightmare that involves hardware, software, and a very specific understanding of how Game Freak handled regional data back in 2004. You can't just "find" them all.
Kanto is small. It’s tight. But it's also locked behind version exclusives and trade requirements that make a solo run impossible. If you want a full National Dex, you aren't just playing Fire Red; you're playing a cross-game puzzle involving Ruby, Sapphire, Emerald, and Leaf Green.
Why You Can’t Catch Every Single Pokémon in Fire Red Alone
The biggest misconception is that "all Pokémon" refers to the 151 original Kanto species. It doesn't. Fire Red introduced the National Dex, expanding the roster to 386. But here is the kicker: the game’s code literally prevents certain spawns from occurring.
Take the version exclusives. If you’re playing Fire Red, forget about Magby, Slowpoke, or Sandshrew. They don't exist in your save file. You need a friend with Leaf Green or a second console and a Link Cable. Yes, an actual physical Link Cable, unless you’re using the Wireless Adapter that came in the original box.
Most people get frustrated because they hit a wall at the Sevii Islands. You finish the Elite Four, you get the Tri-Pass, and you think the rest of the Johto birds or beasts will just show up. They won't. At least, not easily. The legendary beasts—Raikou, Entei, and Suicune—are notoriously buggy in this specific generation. If one of them uses Roar to end the battle, they disappear from the game forever. Just gone. It’s a coding flaw that has haunted speedrunners and collectors for decades.
The Myth of the "Complete" Save File
I've seen so many people claim they found Celebi or Mew in the grass near Pallet Town. They’re lying. Or they're using an Action Replay. In the authentic Pokémon Fire Red all Pokémon experience, Mew and Celebi are "Mythical," meaning they were only available via physical distribution events at places like Toys "R" Us or Pokémon Center stores in the mid-2000s.
Today, the only way to get these onto a legitimate cartridge without cheating is through complex glitches like the Pomeg Glitch in Emerald and then trading them over, or by using fan-made distribution "saves" loaded onto flash carts. It’s a rabbit hole.

The National Dex Grind: Beyond Kanto
Once you secure the Ruby and Sapphire plates for the Network Machine on One Island, the game changes. Suddenly, you can trade with the Hoenn games. This is where the hunt for Pokémon Fire Red all Pokémon gets expensive.
To get the Johto starters—Cyndaquil, Totodile, and Chikorita—you can't even find them in Fire Red or Leaf Green. You have to complete the Hoenn Pokédex in Pokémon Emerald and then choose one from Professor Birch. To get all three? You’re looking at three separate playthroughs of Emerald. It’s a slog.
- The Trade Evolutions: Alakazam, Machamp, Golem, and Gengar. Still need a trade partner.
- The Item Trades: Kingdra, Scizor, Steelix. These require the Metal Coat or Dragon Scale, which are rare drops from wild Magnemite or Horsea.
- The Eevee Dilemma: You get one Eevee in Celadon City. To get Vaporeon, Jolteon, Flareon, Espeon, and Umbreon, you need to breed. But wait—you can't evolve Espeon or Umbreon in Fire Red because the game lacks a real-time clock. You have to trade Eevee to Ruby, Sapphire, or Emerald, evolve it there, and trade it back.
Legendary Bird Management and Roaming Issues
Let's talk about Articuno, Zapdos, and Moltres. They are the easiest part of the late-game hunt, but even they have quirks. Most players accidentally kill them. If you didn't save before the fight, you're done.
The roaming legendary beast is where most people quit their quest for Pokémon Fire Red all Pokémon. The beast that appears depends on your starter.
- If you picked Bulbasaur, you get Entei.
- If you picked Squirtle, you get Raikou.
- If you picked Charmander, you get Suicune.
The IV glitch in Generation 3 means these roamers almost always have terrible stats. Specifically, their Attack IV is hard-coded to be incredibly low, usually 0 to 2, regardless of luck. If you're a competitive player, these specific catches are mostly for the trophy, not for the power.
Where Everyone Gets Stuck: The Safari Zone
The Safari Zone is a nightmare. It’s a RNG-heavy mess. Chansey, Scyther, and Tauros have incredibly low encounter rates and even lower catch rates.

There is a trick, though. If you use the "Repel Trick," you can slightly tilt the odds. If you lead with a Pokémon at a specific level (usually level 26-28 in certain areas), you can block out the low-level "trash" spawns and force the game to check for the rarer encounters. It isn’t foolproof. You will still see plenty of Nidorino. But it’s better than nothing.
Breeding and the Ditto Variable
You need a Ditto. You’ll find them in the Pokémon Mansion or in the cave near Cerulean City. Without Ditto, the quest for Pokémon Fire Red all Pokémon takes twice as long. You need to breed your starters. You need to breed your fossils (Omanyte/Kabuto).
Also, don't forget the Baby Pokémon. Pichu, Cleffa, Igglybuff—these only come from breeding. You won't find a wild Pichu in Viridian Forest. That’s a common mistake people make because they remember the later games where babies show up in the wild. Not here.
The Modern Hardware Problem
It’s 2026. Playing these games on original hardware is getting harder. Capacitors are failing. Cartridge batteries—though Fire Red uses flash memory for saves, so it doesn't "die" like Gold/Silver—can still face corruption.
If you are trying to sync a full collection, you have to be careful about counterfeit cartridges. "All Pokémon" cannot be moved from a fake Fire Red to a real DS game like Pokémon Diamond or Pearl. The "Migrate from GBA" feature on the DS menu will simply never see the fake cartridge. If you've spent 200 hours catching them all on a $10 eBay copy, you might be stuck on that cartridge forever.
Actionable Steps for Completionists
If you are actually going to attempt this, don't just wing it. You need a plan.

Secure your hardware first. You need two GBA-compatible systems. A DS Lite is usually the cheapest way to get a bright screen and a GBA slot.
Map out your version exclusives. Make a list of what you need from Leaf Green (Slowpoke, Staryu, Vulpix, etc.) and what you need from the Hoenn games.
Don't use your Master Ball on the birds. Save it for the roaming beast (Raikou/Entei/Suicune). Trust me. Tracking a teleporter across Kanto for three weeks is not fun. The birds stay in one place; you can eventually catch them with Ultra Balls and patience.
Use a "Catcher" Pokémon. Get a Parasect. It’s one of the few Pokémon in Fire Red that can learn both Spore (100% accuracy sleep) and False Swipe. Level it to 60 or 70. This makes the Safari Zone and legendary hunts significantly less painful.
Verify your fossils. You only get one choice at Mt. Moon. You’ll need to trade for the other one, or play through the game again. The same goes for the Hitmonlee/Hitmonchan choice in Saffron City.
The journey to cataloging every creature in this era of gaming is a test of patience more than skill. It’s a window into a time when "Gotta Catch 'Em All" was actually a difficult, multi-game commitment rather than a weekend hobby. Stick to the caves, keep your Repels handy, and never throw a ball at a shiny without checking your inventory first.
