Pokémon SoulSilver stands as one of the most comprehensive entries in the entire Pokémon franchise. As a remake of the classic Generation II titles, it introduced a revamped Johto Pokédex that expanded beyond the original 251 species to include new evolutions introduced in Generation IV. For completionists, the journey involves filling two distinct catalogs: the Johto Regional Pokédex and the expansive National Pokédex.

Completing these lists requires more than just throwing Poké Balls; it demands an understanding of version exclusives, daily events, radio frequencies, and the integration of the Pokéwalker peripheral. This guide breaks down every essential element of the SoulSilver Pokédex to help collectors achieve the ultimate goal of catching them all.

Understanding the Expanded Johto Regional Pokédex

The Johto Pokédex in SoulSilver is notably different from the one featured in the 1999 original. While the classic Pokédex stopped at Celebi (#251), the SoulSilver version includes 256 entries. The five additions are specific Pokémon that were given new evolutions in the Sinnoh region (Generation IV) which are obtainable in Johto if the player knows the specific move-based evolution requirements.

The Specialized Five: New Johto Evolutions

These five Pokémon are included in the Regional Dex because their pre-evolutions are native to Johto. To evolve them, the pre-evolution must know a specific move when leveling up:

  • Ambipom (#124): Evolves from Aipom when it learns Double Hit (Level 32).
  • Yanmega (#102): Evolves from Yanma when it learns Ancient Power (Level 33).
  • Lickilicky (#181): Evolves from Lickitung when it learns Rollout (Level 33).
  • Tangrowth (#183): Evolves from Tangela when it learns Ancient Power (Level 33).
  • Mamoswine (#197): Evolves from Piloswine when it learns Ancient Power (via Move Tutor in Blackthorn City).

Including these species allows players to use more powerful versions of classic Johto Pokémon without needing to wait for the post-game National Dex.

How to Unlock the National Pokédex in SoulSilver

The National Pokédex is the ultimate challenge, expanding the list to all 493 Pokémon available during the Nintendo DS era. You cannot access this feature during your initial trek through the Johto Gyms.

To unlock the National Pokédex, you must:

  1. Defeat the Elite Four and the Champion, Lance, at the Indigo Plateau.
  2. Watch the credits roll and return to your home in New Bark Town.
  3. Visit Professor Elm in his lab. He will give you the S.S. Ticket.
  4. Head to the port in Olivine City. Before you board the ship to Kanto, Professor Oak will appear and upgrade your device to the National Pokédex.

Once upgraded, you can register Pokémon from the Hoenn and Sinnoh regions, many of which can be found in the Kanto region or via special radio broadcasts.

SoulSilver Version Exclusives and Trade Requirements

One of the primary hurdles in completing the Pokédex is that certain species are physically absent from the SoulSilver game card. To register these, you must trade with a player who owns Pokémon HeartGold.

Pokémon Exclusive to SoulSilver

If you are playing SoulSilver, you have easy access to these Pokémon, which HeartGold players lack:

  • Vulpix and Ninetales: Found on Routes 7, 8, 36, and 37.
  • Meowth and Persian: Common on Routes 5, 6, 7, 8, and others.
  • Ledyba and Ledian: Found in the morning on multiple Johto routes.
  • Teddiursa and Ursaring: Found in Route 45 and Mt. Silver.
  • Delibird: Found in the Ice Path.
  • Skarmory: Found on Route 45.
  • Mawile: Found in the Johto Safari Zone.
  • Gulpin and Swalot: Available via the Swarm mechanic post-National Dex.
  • Lugia: While available in both games, Lugia is the "mascot" of SoulSilver and is encountered at Level 45 in the Whirl Islands (compared to Level 70 in HeartGold).

Pokémon You Must Trade From HeartGold

To finish your Pokédex, you will need to find a way to trade for:

  • Mankey and Primeape
  • Growlithe and Arcanine
  • Spinarak and Ariados
  • Gligar and Gliscor
  • Mantine and Mantyke
  • Phanpy and Donphan
  • Sableye
  • Baltoy and Claydol
  • Kyogre: Specifically required to trigger the Jade Orb event for Rayquaza.

Advanced Catching Mechanics in SoulSilver

SoulSilver utilizes several unique systems to distribute Pokémon. Simply walking through tall grass won't be enough to find the rarest species.

The Headbutt Technique

Many Pokémon like Heracross, Pineco, and Cherubi are found exclusively in trees. You must obtain the TM02 (Headbutt) from a tutor in Ilex Forest. Using this move on small trees across Johto and Kanto will trigger encounters.

  • Pro Tip: Trees in "Special" locations like the mountains of Azalea Town have a higher chance of dropping Heracross, a fan-favorite for early-game power.

The Radio and Regional Sounds

After unlocking the National Dex, the Pokégear Radio becomes your best friend. On Wednesdays and Thursdays, you can tune into specific "sounds" that change the wild encounters in almost every route.

  • Hoenn Sound (Wednesday): Allows you to catch Pokémon like Absol, Linoone, and Whismur in Johto.
  • Sinnoh Sound (Thursday): Allows you to catch species like Shinx, Budew, and Bronzor.

The Pokéwalker Integration

The Pokéwalker is a pedometer that came bundled with the original physical copies of SoulSilver. By transferring a Pokémon to the device and walking in real life, you earn Watts, which unlock new "Routes."

  • Exclusive Routes: Routes like Yellow Forest allowed players to catch Pikachu with rare moves like Fly or Surf.
  • Early Access: The Pokéwalker allows you to catch Pokémon like Kangaskhan or Murkrow long before they appear in the actual game world.

Legendary Pokémon Catching Guide

Legendary encounters are the highlights of the SoulSilver experience. They are often the hardest to catch, requiring specific status ailments (Sleep and Paralysis are highly recommended) and dozens of Ultra Balls or Dusk Balls.

The Johto Trio: Lugia, Ho-Oh, and the Beasts

  • Lugia: Located deep within the Whirl Islands. You need the Silver Wing (given by the Radio Tower manager) and the Tidal Bell (given by the Kimono Girls). In SoulSilver, you face it at Level 45.
  • Ho-Oh: Found atop the Bell Tower in Ecruteak City. In SoulSilver, you only get the Rainbow Wing from an NPC in Pewter City (Kanto), making it a Level 70 post-game encounter.
  • Entei and Raikou: These roam across the Johto map after you release them from the Burned Tower. Use the Pokégear map to track their location. They flee immediately, so a Pokémon with the "Mean Look" move or the "Shadow Tag" ability is essential.
  • Suicune: Unlike the other two beasts, Suicune is a stationary encounter. You must track it across Johto and Kanto (Cianwood, Mt. Mortar, Route 42, Vermilion, Route 14) until it finally settles at Route 25 near Bill’s house.

The Kanto Classics and Beyond

  • Articuno, Zapdos, and Moltres: Articuno is in the Seafoam Islands, Zapdos is outside the Power Plant (Route 10), and Moltres is in Mt. Silver.
  • Mewtwo: Accessible in Cerulean Cave only after obtaining all 16 badges.
  • The Weather Trio: After getting the National Dex and defeating Red, you can get the Blue Orb (SoulSilver) to catch Kyogre in the Embedded Tower. If you trade for a HeartGold Kyogre and show both to Professor Oak, he gives you the Jade Orb to encounter Rayquaza.

Detailed Johto Pokédex List and Key Locations

Here is a breakdown of key sections of the 256-species Johto Pokédex with specific notes on where to find the most important members.

The Starters (001 - 009)

You can only pick one at the start of the game. Completing the Pokédex requires trading for the other two.

  • Chikorita, Bayleef, Meganium: Grass-type.
  • Cyndaquil, Quilava, Typhlosion: Fire-type.
  • Totodile, Croconaw, Feraligatr: Water-type.

Early Route Commons (010 - 029)

These fill the early slots of your Dex and are found primarily between New Bark Town and Violet City.

  • Pidgey (#010): Everywhere during the day.
  • Hoothoot (#015): The nighttime equivalent of Pidgey.
  • Sentret (#019): Route 29 commonality.
  • Rattata (#017): Found in almost every cave and grassy patch.
  • Caterpie/Weedle (#024/#027): Look for these in the Bug-Catching Contest at the National Park on Tuesdays, Thursdays, and Saturdays for the best encounter rates.

The "Baby" Pokémon (145, 152, 154, 156, 158, 212)

Generation II was famous for introducing babies. In SoulSilver, many are obtained through breeding at the Day Care on Route 34.

  • Pichu (#021): Breed a Pikachu/Raichu.
  • Cleffa (#040): Breed a Clefairy/Clefable.
  • Igglybuff (#043): Breed a Jigglypuff/Wigglytuff.
  • Togepi (#046): Obtained as an egg from Professor Elm’s assistant in the Violet City Poké Mart.
  • Tyrogue (#145): Given by the Karate King in Mt. Mortar if you have an empty slot in your party.

Mid-Game Rarities (050 - 150)

  • Sudowoodo (#107): A one-time encounter blocking the path at Route 36. You must use the SquirtBottle from the Goldenrod Flower Shop.
  • Unown (#061): Found in the Ruins of Alph. There are 28 different forms (A-Z, !, ?). Catching them all is a sub-quest that rewards you with unique Pokédex entries for each letter.
  • Lapras (#224): Appears every Friday deep inside Union Cave. You must have the HM Surf to reach it.
  • Red Gyarados (#077): A guaranteed Shiny encounter at the Lake of Rage. While it's just a Gyarados, it is a vital part of the Johto story.

The Late-Game Powerhouses (246 - 251)

  • Larvitar, Pupitar, Tyranitar: The "Pseudo-Legendary" of Johto. Found in the Safari Zone or very late in the game at Mt. Silver.
  • Dratini, Dragonair, Dragonite: Can be bought at the Goldenrod Game Corner or caught in the Dragon’s Den.
  • Lugia/Ho-Oh (#249/#250): The legendary birds described previously.
  • Celebi (#251): Historically an event-only Pokémon. In the original DS version, it cannot be caught during normal gameplay without an event item (the GS Ball).

Specialized Evolution Items in SoulSilver

Many Pokémon in the National Dex and some in the Johto Dex require specific items to evolve. Knowing where to find these is crucial for Dex completion.

The Daily Pokéathlon

The Pokéathlon Dome, located next to the National Park, is the most consistent source for evolution stones. By participating in mini-games, you earn Athlete Points (AP). The shop's inventory changes daily:

  • Moon Stones: Available Monday/Wednesday.
  • Fire/Thunder/Water Stones: Rotates through the week.
  • Shiny/Dusk/Dawn Stones: Usually available post-National Dex for a high AP cost.

Trade Items with Held Objects

Several Johto favorites only evolve when traded while holding a specific item:

  • Steelix (#063): Trade Onix holding a Metal Coat.
  • Scizor (#112): Trade Scyther holding a Metal Coat.
  • Kingdra (#192): Trade Seadra holding a Dragon Scale.
  • Politoed (#075): Trade Poliwhirl holding a King’s Rock.
  • Slowking (#082): Trade Slowpoke holding a King’s Rock.

Rewards for Completing the Pokédex

What do you get for all this effort? Aside from the immense satisfaction of a full list, there are tangible in-game rewards.

  1. Johto Diploma: Show your completed Johto Pokédex (all 256 species, excluding mythical Pokémon like Celebi) to the Game Designer in the Celadon Condominiums (Kanto). He will award you a diploma for your room.
  2. National Diploma: Achieved after catching all 493 Pokémon. This is the ultimate proof of a Pokémon Master.
  3. The Shiny Charm? Note that the Shiny Charm was not introduced until Black 2 and White 2. In SoulSilver, the reward is primarily the diplomas and the ability to say you’ve conquered the most content-heavy game in the series.
  4. Trainer Card Upgrades: Completing the Pokédex is one of the requirements to change the color of your Trainer Card. Reaching the "Five Star" rank requires completing the National Dex, defeating the Elite Four, winning at the Battle Frontier, and more.

Frequently Asked Questions About the SoulSilver Pokédex

How many Pokémon are in the SoulSilver Pokédex?

The Johto Regional Pokédex contains 256 Pokémon. The National Pokédex expands this to a total of 493 Pokémon, covering every species from Generations I through IV.

Can I get Bulbasaur, Charmander, or Squirtle in SoulSilver?

Yes. After you defeat Red at the summit of Mt. Silver, visit Professor Oak in Pallet Town. He will allow you to choose one of the three original Kanto starters.

Is Mew available in the SoulSilver Pokédex?

Mew is species #151 in the National Pokédex. It is not available through normal gameplay in SoulSilver. It was originally distributed through limited-time Nintendo Wi-Fi Connection events. To get one today, you would need to trade from an older save file or use the Poké Ball Plus in much later games (though that doesn't help with DS completion).

Do I need Celebi to complete the Johto Pokédex?

No. For the purposes of receiving the Diploma from the Game Designer, "Event-Only" Pokémon (Mythicals) like Celebi, Mew, Jirachi, Deoxys, Phione, Manaphy, Darkrai, Shaymin, and Arceus are not required.

How do I find the "Mass Outbreaks" or Swarms?

Check the radio or talk to Professor Oak's aide. Every day, a specific rare Pokémon will "swarm" in a particular route. This is often the only way to catch Pokémon like Snubbull, Marill, or Yanma with high encounter rates.

Summary of Pokédex Completion Tips

Completing the Pokémon SoulSilver Pokédex is a marathon, not a sprint. To succeed, follow these strategic steps:

  • Catch as you go: Don't skip encounters on new routes. Even common Pokémon take time to track down later.
  • Check the clock: Many Pokémon like Gastly, Murkrow, and Misdreavus only appear at night. Others, like Ledyba, are morning-exclusive.
  • Use the Safari Zone: The Johto Safari Zone is highly customizable. By placing "objects" like trees or rocks and waiting for specific numbers of days, you can attract non-native Pokémon like Gible or Riolu.
  • Sync with Friends: You cannot finish the Dex without a HeartGold partner. Plan your trades for version exclusives and trade-evolutions early.
  • Master the Pokéathlon: It is the most reliable way to get the stones needed for the many Eevee evolutions and other stone-based species.

By mastering the unique mechanics of the Johto region and the post-game Kanto expansion, you will eventually fill every slot in the most iconic Pokédex in history.
