Pokémon FireRed and Pokémon LeafGreen are almost the same adventure. They share the Kanto map, starter choices, Gym order, Elite Four, and Sevii Islands. The meaningful difference is which Pokémon appear in the wild, with a smaller set of post-game Johto encounters also split between versions. Choose the game that contains the Pokémon you want on your team; if you can trade with the other version or a compatible Generation III game, either edition can supply the missing set.
What FireRed and LeafGreen have in common
Both games remake the original Kanto adventure and follow the same broad progression. You begin with the same three starter choices—Bulbasaur, Charmander, or Squirtle—then challenge the same eight Gyms before facing the Elite Four. The story, map progression, core mechanics, and Sevii Islands content are shared rather than being separate campaigns.
Nintendo describes the Switch editions as broadly retaining the contents of the original releases. That means choosing a version does not give you a different difficulty setting, a different Gym sequence, or a different ending. Your decision mainly changes the wild-encounter table and therefore the Pokémon you can catch without trading.
The shared structure is important when comparing the games. You are not choosing between two routes through Kanto, two rival stories, or two different post-game maps. You are choosing which encounters appear naturally during that structure. A player who selects the same starter and builds a similar party will experience nearly the same battles and milestones in either edition.

Both versions also use the Sevii Islands as an extension of the adventure after the main Kanto sequence. The islands provide additional areas, story tasks, and opportunities to expand the roster, but they do not erase the central version split. A species that is exclusive to the other game does not automatically become available just because you reach the post-game islands.
Version-exclusive Pokémon
“Version-exclusive” means that a Pokémon cannot be caught in the other paired game through normal encounters. You must trade it from the opposite version or, where supported, from another compatible Generation III title. The table below groups the practical exclusive lines and post-game species documented for FireRed and LeafGreen.
| Pokémon or evolution line | FireRed | LeafGreen | What this means |
|---|---|---|---|
| Ekans, Arbok | Exclusive | Not catchable | Trade from FireRed to use the line in LeafGreen. |
| Sandshrew, Sandslash | Not catchable | Exclusive | Trade from LeafGreen to use the line in FireRed. |
| Oddish, Gloom, Vileplume | Exclusive | Not catchable | FireRed supplies this Grass line. |
| Bellsprout, Weepinbell, Victreebel | Not catchable | Exclusive | LeafGreen supplies this Grass line. |
| Psyduck, Golduck | Exclusive | Not catchable | Choose FireRed if this Water line matters to your team. |
| Slowpoke, Slowbro | Not catchable | Exclusive | LeafGreen offers this Water/Psychic line instead. |
| Growlithe, Arcanine | Exclusive | Not catchable | FireRed is the straightforward choice for Arcanine. |
| Vulpix, Ninetales | Not catchable | Exclusive | LeafGreen is required to catch this Fire line. |
| Shellder, Cloyster | Exclusive | Not catchable | FireRed supplies Shellder and its evolution. |
| Staryu, Starmie | Not catchable | Exclusive | LeafGreen supplies this Water line. |
| Scyther | Exclusive | Not catchable | Trade is required to obtain Scyther in LeafGreen. |
| Pinsir | Not catchable | Exclusive | Trade is required to obtain Pinsir in FireRed. |
| Electabuzz | Exclusive | Not catchable | FireRed has the encounter; LeafGreen needs a trade. |
| Magmar | Not catchable | Exclusive | LeafGreen has the encounter; FireRed needs a trade. |
| Wooper, Quagsire | Exclusive | Not catchable | These are FireRed-side post-game options. |
| Marill, Azumarill | Not catchable | Exclusive | These are LeafGreen-side post-game options. |
| Murkrow | Exclusive | Not catchable | Trade from FireRed for this Dark/Flying Pokémon. |
| Misdreavus | Not catchable | Exclusive | Trade from LeafGreen for this Ghost Pokémon. |
| Skarmory | Exclusive | Not catchable | FireRed is the version with the Steel/Flying encounter. |
| Qwilfish, Sneasel, Mantine | Not catchable | Exclusive | These additional Johto encounters are LeafGreen-side exclusives. |
The complete route-by-route encounter table is more detailed than this headline list, because some exclusives appear only in particular areas or after story milestones. Bulbapedia’s current version-exclusive reference is the best place to verify a specific species before planning a completion run.

Catching Oddish in FireRed gives you access to its later forms, while a LeafGreen player must trade for the family rather than merely wait for a later route. The same principle applies to Growlithe, Vulpix, the two Grass lines, and the paired Water families. If your intended team includes a particular final evolution, check its first-stage availability before you start.
Some entries are especially relevant to collectors because they are not ordinary early-route replacements. Scyther and Pinsir, Electabuzz and Magmar, and the Johto species may be planned for a specific battle team or a Pokédex goal rather than used immediately. Their version status still matters: reaching the appropriate late-game area in the wrong version will not make the encounter appear.
How the exclusives change team building
Fire and Grass choices
FireRed naturally favors players who want Growlithe and Arcanine, while LeafGreen favors Vulpix and Ninetales. The Grass split is equally clear: FireRed has the Oddish line and LeafGreen has Bellsprout’s line. If your intended party depends on one of those lines, select that version unless you already have a trading partner.
The two Grass families can fill a similar broad role, but they are not interchangeable for a collector or a planned moveset. Choosing the version that contains the line lets you catch its first stage yourself and develop it throughout the story. Choosing the other version means waiting for a trade, which may be inconvenient if you want that Pokémon from the beginning of your run.

FireRed gives you Psyduck and Golduck plus Shellder and Cloyster. LeafGreen instead provides Slowpoke and Slowbro plus Staryu and Starmie. Those alternatives affect more than type coverage: they offer different stat profiles, moves, and evolution methods, so the choice can shape how you handle the middle and late portions of the story.
This split is useful when you already know what kind of Water-type team you want. A player planning around Starmie should start with LeafGreen, while a player who specifically wants Cloyster should start with FireRed. Trading later can provide the opposite line, but it is worth remembering that a traded Pokémon may arrive at a different level or with a different original trainer, so catching your preferred line yourself can make team planning simpler.

Bug, Electric, Steel, Dark, and later Johto options
Scyther, Electabuzz, Murkrow, and Skarmory are FireRed exclusives. LeafGreen counters with Pinsir, Magmar, Misdreavus, and several post-game Johto encounters, including Sneasel and Mantine. These Pokémon are not necessary to finish the main story, but they matter if you are building a themed party, filling the Pokédex, or preparing a team for battles after the credits.
The post-game split can be easy to overlook because it does not affect the opening routes. If your goal is a Johto-themed collection, decide on the version before you invest in a long file. FireRed supplies Wooper, Quagsire, and Murkrow among its later options, while LeafGreen supplies Marill, Azumarill, Qwilfish, Sneasel, Mantine, and Misdreavus. These encounters can become the deciding factor for a post-game party even when the main-story roster looked similar.

Can one game complete the Pokédex?
No. A single copy cannot provide every Pokémon needed for a complete National Pokédex. Bulbapedia’s current reference counts 212 Pokémon available in-game across FireRed and LeafGreen, but that combined figure is not the number obtainable in one uninterrupted save file.
Several separate limitations are involved:
- The two versions divide wild encounters, so each copy lacks the other game’s exclusives.
- You can choose only one of the three starters in a normal playthrough; the other two require trades or additional game activity.
- Fossil choices also split available Pokémon, meaning one save cannot claim every fossil line without exchanging one.
- Some evolutions require trading rather than leveling in the same game.
- Some National Pokédex entries depend on compatible Hoenn games, event distributions, or other Generation III connectivity.
Therefore, “complete the Pokédex” can mean different targets. Finishing the regional Kanto entries is a smaller task than obtaining every National Pokédex entry. Decide which target you want before buying hardware or arranging trades.
For a regional completion attempt, make a checklist that distinguishes “caught,” “seen,” and “evolved.” A traded starter or fossil may fill an entry, but it does not remove the need to plan for the other version’s exclusive families. For a National Pokédex attempt, add the starter, fossil, trade-evolution, Hoenn, and event requirements to that checklist from the start. The 212-species combined figure describes what the paired FireRed and LeafGreen releases can provide in-game; it is not a promise that one cartridge, one save, or one player can obtain all of it alone.
Trading requirements on original Game Boy Advance hardware
The original instruction manual documents connectivity between FireRed, LeafGreen, Pokémon Ruby, Pokémon Sapphire, and Pokémon Colosseum. On Game Boy Advance hardware, you need compatible systems and a supported connection accessory. The Game Boy Advance Wireless Adapter was sold separately and is the accessory specifically identified for wireless trading and battling; a Game Boy Advance Game Link cable is another documented connection method.
Original-hardware checklist
- Prepare two compatible Generation III games, such as FireRed and LeafGreen, or one of the supported Ruby, Sapphire, or Colosseum combinations.
- Use compatible Game Boy Advance systems and connect them with a Game Link cable or the supported Wireless Adapter.
- Load both games and enter their in-game link or trading area, following the prompts shown on each screen.
- Select the Pokémon to exchange and confirm on both systems. Keep a written list of the species you still need so you do not trade away a unique team member accidentally.
- For a full completion project, repeat the process for version exclusives, the two starters you did not choose, fossil results, and trade-evolution Pokémon.
Accessory compatibility is the practical constraint on original hardware. A cartridge alone does not provide a way to exchange Pokémon with another cartridge unless you also have the required second system and connection equipment.
Budget for the complete setup rather than only the game cartridge. The Wireless Adapter was sold separately, and a cable-based setup still requires the appropriate cable and a second compatible system. The exact price depends on the condition and source of used hardware, so treat the accessory as an additional purchase rather than assuming it is included with FireRed or LeafGreen.
Trading with Ruby, Sapphire, or Colosseum can broaden the pool, but it does not turn one FireRed or LeafGreen save into a self-contained National Pokédex. You still need the compatible game, hardware, and the correct connection method, and some entries remain tied to starters, fossils, events, or other Generation III requirements.

Trading on the Switch editions
Nintendo’s current support information says the Switch versions move the original connectivity features to built-in local wireless. You do not need the old Game Link cable or the Game Boy Advance Wireless Adapter when both players are using the Switch editions and have compatible local-wireless access.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesThe Switch editions are distributed as digital software, and Nintendo says they will not receive physical releases. That matters if you are choosing between a modern digital playthrough and collecting original cartridges: the availability and accessory requirements are different even though the underlying adventure is broadly the same.
Switch trading checklist
- Install the compatible digital editions on the participating Switch systems.
- Make sure both players are nearby and that local wireless is enabled.
- Open the games’ trading function and follow the on-screen pairing prompts.
- Exchange the missing exclusives, starters, fossils, or trade-evolution candidates, then verify the Pokédex entries before ending the session.
Local wireless changes the equipment question, not the version split. You still need access to the other edition, another player, or another compatible save to obtain species that do not appear in your copy. If you plan to play alone, check whether you have two compatible Switch systems and both digital editions before assuming that “local wireless” means a single purchase can supply both sides.
FireRed or LeafGreen: a practical decision guide
Choose FireRed when
- You want Growlithe or Arcanine without relying on another player.
- You prefer the Oddish line, Psyduck line, Shellder line, Scyther, Electabuzz, Murkrow, or Skarmory.
- You are interested in the FireRed-side Johto encounters, including Wooper, Quagsire, and Murkrow.
- You are buying one cartridge or digital edition and cannot assume a later trade.
Choose LeafGreen when
- You want Vulpix or Ninetales without trading.
- You prefer Bellsprout, Slowpoke, Staryu, Pinsir, Magmar, Misdreavus, Sneasel, Qwilfish, or Mantine.
- You want the LeafGreen-side Johto encounters, including Marill and Azumarill.
- You are playing alone and want the broadest match for a team built around those species.
Choose based on a team plan, not a supposed difficulty difference
Neither version is established as objectively harder. The Gym order, Elite Four, and main progression are shared, so difficulty claims usually confuse a player’s team choice with a game-design difference. Write down the six Pokémon you most want, mark which version provides each one, and let that list decide. If none of your priorities are exclusive, the editions are effectively equivalent for the story.
If you can trade locally
Local trading makes the choice largely a preference. Buy the version whose early encounters you prefer, then import the opposite version’s exclusives later. This is especially useful for players who want one specific Pokémon immediately but still plan to complete the National Pokédex.

If you cannot trade
Treat the exclusive table as a buying checklist. Do not choose based on the box art, a presumed difficulty level, or the idea that one game has a longer campaign. Without trading, the species available in your own version are the permanent limits of that save file, aside from choices that can be covered by starting over or using additional compatible games.
Completion-run planning
A little planning prevents the most common dead ends. Use this sequence before beginning a serious collection file:
- Choose FireRed or LeafGreen by checking your must-have team members against the exclusive table.
- Record which starter you are taking and which two starters will have to come from another save or a trade.
- Decide which fossil you want and arrange a trade for the other fossil result if your goal includes both.
- Reserve a trade session for version exclusives rather than assuming every missing species can be found on the Sevii Islands.
- Mark any trade-evolution Pokémon separately; owning the unevolved species is not the same as completing its evolution entry.
- If your target is the National Pokédex rather than the Kanto regional list, identify the compatible Hoenn-game and event requirements before investing in the final entries.
- On original hardware, confirm that you have the second system and cable or Wireless Adapter. On Switch, confirm that all participants have the digital editions and local-wireless access.
Keep duplicate copies of rare or unique team members until your checklist is complete. It is easy to trade a Pokémon needed for a battle team and then discover that replacing it requires another trip through the opposite version. Label boxes or maintain a written list for exclusives, starters, fossils, and trade evolutions so the collection process stays separate from ordinary story play.

- Gym sequence: the same eight Gyms and progression.
- Elite Four: the same end-of-story challenge structure.
- Sevii Islands: included in both versions as post-game content.
- Campaign length: no evidence establishes one version as having a different main adventure.
- Difficulty: the version split is about encounters and team options, not an objectively harder game.
The differences that do matter are the encounter table, the resulting team-building options, the post-game Johto species available on each side, and whether you have a practical way to trade.

Bottom line for buyers
Pick FireRed for its exclusive encounter set, especially if Arcanine, the Oddish line, Scyther, Electabuzz, Murkrow, or Skarmory is central to your plan. Pick LeafGreen if you want Ninetales, the Bellsprout line, Slowbro, Starmie, Magmar, Sneasel, or Mantine. With local trading, either version works and the decision becomes personal preference. Without trading, the exclusive list is the deciding factor, because one save cannot contain every Pokémon from both games.
Frequently Asked Questions
Are FireRed and LeafGreen different campaigns?
No. They share the Kanto adventure, starter choices, eight-Gym order, Elite Four structure, and Sevii Islands content. The major difference is which Pokémon appear in the wild, plus several post-game encounters.
Which version is better if I cannot trade?
Neither is universally better. Choose the version containing the Pokémon you want most, such as Arcanine and Scyther in FireRed or Ninetales and Starmie in LeafGreen. Without trading, those exclusive encounters are unavailable in the other paired game.
Can one copy provide a complete National Pokédex?
No. The two games split wild encounters, and completion also involves starter and fossil choices, trade evolutions, compatible Hoenn games, and some event requirements. Bulbapedia counts 212 Pokémon available in-game across FireRed and LeafGreen, not all in one save.
Can I trade with Pokémon Ruby or Sapphire?
The original manual documents connectivity with Ruby, Sapphire, LeafGreen, FireRed, and Pokémon Colosseum, provided you have compatible hardware and the required cable or Wireless Adapter.
Do the Switch editions need a Game Boy Advance Wireless Adapter?
No. Nintendo says the Switch editions use built-in local wireless instead of the original Game Link cable or Wireless Adapter. The Switch software is digital and will not receive physical releases.
Which version has Growlithe, Vulpix, Scyther, and Pinsir?
Growlithe and Scyther are FireRed exclusives. Vulpix and Pinsir are LeafGreen exclusives.
Are the Johto Pokémon also version-exclusive?
Yes. FireRed includes post-game options such as Wooper, Quagsire, and Murkrow, while LeafGreen includes Marill, Azumarill, Qwilfish, Sneasel, Mantine, and Misdreavus among its side of the split.
Do I need both versions to enjoy the story?
No. Either game contains the complete Kanto story, Gym progression, Elite Four, and Sevii Islands. Both versions are fully playable on their own; the second version is mainly useful for trading and collection goals.
The Bottom Line
Choose by encounter availability. FireRed is the pick for Arcanine, Oddish, Scyther, Electabuzz, Murkrow, and Skarmory; LeafGreen is the pick for Ninetales, Bellsprout, Slowbro, Starmie, Magmar, Sneasel, and Mantine. If you can trade, either version works. If you cannot, your preferred exclusives should decide.
