The Hoenn Pokédex in Pokémon Emerald remains one of the most balanced and engaging regional rosters in the history of the series. Consisting of 202 Pokémon in the local listing before expanding to the National Dex, completing the Pokemon Emerald dex requires a combination of exploration, strategic breeding, and understanding specific environmental triggers. This version is unique compared to its predecessors, Ruby and Sapphire, as it introduces new sprite animations, different encounter rates, and the ability to capture both flagship legendaries within a single save file.

The Hoenn Starters: Entries 001 to 009

Every journey through the Pokemon Emerald dex begins at Route 101 with a choice provided by Professor Birch. Each starter line follows a consistent evolution pattern at levels 16 and 36.

  • Treecko (001), Grovyle (002), Sceptile (003): The Grass-type line. Treecko is a high-speed choice. Grovyle evolves at level 16, and Sceptile at level 36. Sceptile is a pure Grass type with exceptional Special Attack and Speed, making it effective against the numerous Water-type trainers in the late game.
  • Torchic (004), Combusken (005), Blaziken (006): The Fire-type line. Upon evolving into Combusken at level 16, it gains the Fighting type. This dual typing is highly advantageous against Normal and Ice types. Blaziken is reached at level 36 and serves as a powerful mixed attacker.
  • Mudkip (007), Marshtomp (008), Swampert (009): The Water-type line. Marshtomp (level 16) and Swampert (level 36) gain the Ground typing. This is arguably the most resilient choice for completing the dex, as its only major weakness is Grass. Its immunity to Electric moves provides a significant tactical edge against the third Gym Leader.

Early Game Encounters: Routes 101 to 110

The initial routes are populated with the standard "early-game" types that help fill the first twenty slots of the Pokemon Emerald dex quickly.

  • Poochyena (010) & Mightyena (011): These Dark types are ubiquitous. Poochyena evolves into Mightyena at level 18. They provide the Intimidate ability, which is useful for mitigating physical damage.
  • Zigzagoon (012) & Linoone (013): Found on almost all early routes. Zigzagoon evolves at level 20. Their real value lies in the Pickup ability, which allows them to find rare items like Rare Candy or Ultra Balls simply by being in the party.
  • Wurmple (014) and the Branching Evolution: Wurmple is a unique case in the Hoenn dex. Its evolution into Silcoon (015) or Cascoon (017) at level 7 is determined by a hidden personality value, not player choice. Silcoon leads to Beautifly (016) at level 10, while Cascoon leads to Dustox (018) at level 10.
  • Lotad (019) & Seedot (022): In Emerald, both are available, though their encounter rates differ by route. Lotad evolves into Lombre (020) at level 14 and requires a Water Stone for Ludicolo (021). Seedot evolves into Nuzleaf (023) at level 14 and requires a Leaf Stone for Shiftry (024).
  • Ralts (029): Located on Route 102. Ralts is a rare encounter (4% chance) but highly sought after for its Psychic typing. It evolves into Kirlia (030) at level 20 and Gardevoir (031) at level 30.

Navigating the Forests and Caves

As the player moves toward the first and second Gyms, the Pokemon Emerald dex begins to include Bug, Fighting, and Rock types found in restricted environments.

  • Petalburg Woods: Home to Shroomish (034), which evolves into the Grass/Fighting Breloom (035) at level 23. This is also where you find Slakoth (036). Slakoth evolves into Vigoroth (037) at level 18, and eventually the massive Slaking (038) at level 36. While Slaking has legendary-tier stats, its Truant ability means it only moves every other turn.
  • Rusturf Tunnel & Granite Cave: Whismur (045) is a common Normal type here, evolving into Loudred (046) at level 20 and Exploud (047) at level 40. In Granite Cave, players can find Makuhita (048), which evolves into Hariyama (049) at level 24. This cave is also the primary location for Aron (070), a Steel/Rock type that evolves into Lairon (071) at level 32 and Aggron (072) at level 42.
  • Nincada (042): Found on Route 116. This is a special entry in the Pokemon Emerald dex. If the player evolves Nincada into Ninjask (043) at level 20 while having an empty slot in the party and a spare Poké Ball, a Shedinja (044) will spontaneously appear in the party. Shedinja is a Bug/Ghost type with only 1 HP but the Wonder Guard ability, making it immune to any move that isn't super effective.

The Mid-Game Elemental Shift

The central portion of the Hoenn region introduces a wider variety of types, particularly those associated with the volcanic areas and the central plains.

  • Electrike (078) & Manectric (079): These are the primary Electric types for many players, found on Route 110. Electrike evolves at level 26.
  • Volbeat (086) & Illumise (087): Found in the tall grass of Route 117. They are rare but essential for completing the local dex. They do not evolve but are notable for their unique movesets.
  • The Poison Lines: Gulpin (095) evolves into Swalot (096) at level 26. Grimer (106) and Koffing (108) can be found in Fiery Path and the Heat Path areas, evolving into Muk (107) and Weezing (109) at levels 38 and 35, respectively.
  • Torkoal (105): A pure Fire-type with high Defense, found in Fiery Path. It does not evolve, but it is a stalwart defensive option.
  • Trapinch (116): Located in the desert of Route 111. It evolves into Vibrava (117) at level 35, gaining the Dragon type, and finally Flygon (118) at level 45. Flygon is a fan favorite for its Ground/Dragon typing and Levitate ability.

Water Routes and Deep Sea Exploration

Given Hoenn's geography, a significant portion of the Pokemon Emerald dex is occupied by Water types. Accessing these requires the HMs Surf and Dive.

  • Wailmer (099) & Wailord (100): Wailmer can be caught by fishing in almost any body of water. It evolves into the gargantuan Wailord at level 40. Wailord is famously required for the Regi-trio side quest.
  • Feebas (140) & Milotic (141): This is perhaps the most difficult duo to secure in the Pokemon Emerald dex. Feebas appears only on six random tiles on Route 119. These tiles change if the "Trendy Phrase" in Dewford Town is altered. Once caught, Feebas evolves into Milotic only when its Beauty stat is maximized via Pokéblocks and it is then leveled up.
  • Staryu (143): Caught by fishing in Lilycove City. It evolves into Starmie (144) using a Water Stone. Starmie remains a top-tier choice for its high Speed and diverse movepool.
  • Relicanth (179): Found in the underwater seaweed using Dive. It has a low encounter rate (around 5%) but, like Wailord, is essential for unlocking the sealed chambers of the legendary golems.

The Fossil Pokémon

In the desert of Route 111, players will encounter the Mirage Tower. Upon reaching the top, you must choose between the Root Fossil and the Claw Fossil.

  • Lileep (133): Revived from the Root Fossil. It is a Rock/Grass type that evolves into Cradily (134) at level 40.
  • Anorith (135): Revived from the Claw Fossil. It is a Rock/Bug type that evolves into Armaldo (136) at level 40.
  • Note: In Pokémon Emerald, unlike Ruby and Sapphire, the fossil you did not choose will eventually become available in the post-game at the back of the Fossil Maniac's house near Fallarbor Town.

The Legendary Entities of Emerald

Completing the Pokemon Emerald dex requires capturing the powerful legendary beings that define the Hoenn lore. Emerald allows for more legendary captures in a single game than its predecessors.

  • Rayquaza (200): The mascot of Emerald. It can be found at the top of Sky Pillar. Unlike Groudon and Kyogre, Rayquaza can be caught before the Elite Four, though it is at level 70, making it significantly more powerful than the player's team at that stage.
  • Groudon (199) & Kyogre (198): After defeating the Elite Four, the Weather Institute will alert the player to unusual weather patterns. Groudon is found in Terra Cave (drought conditions), and Kyogre is found in Marine Cave (heavy rain). These locations rotate among several routes, requiring the player to act quickly once the location is identified.
  • The Regi Trio: Regirock (193), Regice (194), and Registeel (195). To encounter them, you must first solve the puzzle in the Sealed Chamber (Route 134) involving Wailord and Relicanth. This unlocks the ruins located in the desert, Island Cave, and Ancient Tomb.
  • Latios (197) & Latias (196): After the Elite Four, the player's mother will ask what color the bird on TV was. Selecting "Red" causes Latias to roam Hoenn; selecting "Blue" causes Latios to roam. The one not chosen can typically only be found via the Eon Ticket event.

Evolution Stone Requirements

Several entries in the Pokemon Emerald dex cannot be obtained through leveling alone. You must find or trade for specific stones.

  1. Water Stone: Lombre to Ludicolo, Staryu to Starmie.
  2. Leaf Stone: Nuzleaf to Shiftry, Gloom to Bellossom (though Gloom can also use a Sun Stone).
  3. Fire Stone: Vulpix to Ninetales.
  4. Thunder Stone: Pikachu to Raichu.
  5. Moon Stone: Skitty to Delcatty, Jigglypuff to Wigglytuff.
  6. Sun Stone: Gloom to Bellossom.

Shards (Blue, Red, Yellow, Green) found underwater can be traded to the Treasure Hunter on the route near Mossdeep City to acquire these stones in greater quantities.

The Challenge of Trade Evolutions

A hurdle for many in finishing the Pokemon Emerald dex is the requirement for trading. Some Pokémon only evolve when traded between two Game Boy Advance systems (or via emulated link cables).

  • Kadabra to Alakazam (041)
  • Machoke to Machamp (075)
  • Graveler to Golem (059)
  • Haunter to Gengar (National Dex)
  • Clamperl (176) branching evolution: Clamperl evolves into Huntail (177) if traded while holding a DeepSeaTooth, or Gorebyss (178) if traded while holding a DeepSeaScale.

The National Dex and Beyond

Once the Elite Four is defeated and the player has traded with a Kanto-based game (FireRed/LeafGreen) or simply met the in-game requirements in Emerald, the Pokédex is upgraded to the National Dex. This adds several hundred more entries from the Kanto and Johto regions.

In the Safari Zone expansion (accessible after the Elite Four), players can find various Johto Pokémon such as Aipom, Gligar, and Shuckle. Furthermore, Professor Birch will offer the player one of the three Johto starters—Chikorita, Cyndaquil, or Totodile—after the player has successfully registered all 202 Pokémon in the Hoenn Pokédex. This serves as the ultimate reward for regional completion.

Summary of Completion Tips

To efficiently fill the Pokemon Emerald dex, consider the following strategies:

  • Catch and Release: Don't hesitate to catch every new species seen, even if it won't be used in battle. You can always release it later to save box space.
  • The Pickup Squad: Keep a few Zigzagoon in your party while traveling. The items they find can be sold to buy more Poké Balls.
  • Strategic Breeding: Some baby Pokémon like Azurill (054) or Wynaut (160) are easier to obtain via breeding parents holding specific Incense items (Sea Incense and Lax Incense).
  • Version Exclusives: Remember that while Emerald is the definitive version, some Pokémon like Zangoose or Lunatone may still require a trade from Ruby or Sapphire depending on the specific encounter tables of your save file (though Emerald includes many that were previously exclusive).

Completing the dex is a test of endurance and knowledge of the Hoenn region's diverse ecosystems. Whether you are searching for the elusive Feebas or scaling the Sky Pillar for Rayquaza, each entry brought into the dex brings you closer to being recognized as a true Hoenn Master.
