How to Get Flash in Pokémon Silver: 6 Steps

Note: This guide covers the original Pokémon Silver for Game Boy/Game Boy Color and the 3DS Virtual Console version. If you are playing Pokémon SoulSilver on Nintendo DS, the route is similar, but Flash is handled differently in that generation.

Introduction: Why Everyone Wants Flash in Pokémon Silver

In Pokémon Silver, Flash is one of those moves that sounds optional until you step into a dark cave and suddenly feel like your trainer forgot to pack batteries. Technically, you can wander through certain caves without it. Realistically, unless you enjoy walking into invisible walls like a confused Zubat, you will want HM05 Flash as soon as possible.

Flash is a Hidden Machine, also called an HM, that teaches a compatible Pokémon the move Flash. In battle, Flash lowers the opponent’s accuracy. Outside battle, it lights up dark caves so you can actually see where you are going. That makes it especially helpful for areas like Dark Cave, Mt. Mortar, Whirl Islands, Rock Tunnel, and Mt. Silver later in your Johto and Kanto adventure.

The good news? Getting Flash in Pokémon Silver is straightforward. You do not need a secret cheat code, a suspicious playground rumor, or your cousin’s friend’s GameShark. You simply need to reach Violet City, climb Sprout Tower, defeat the Elder at the top, and make sure you have the Zephyr Badge so Flash can be used outside battle.

This complete guide explains how to get Flash in Pokémon Silver in 6 steps, which Pokémon should learn it, what to watch out for in Sprout Tower, and how to avoid common beginner mistakes.

What Is Flash in Pokémon Silver?

Flash is HM05 in Pokémon Silver. Unlike regular TMs in the original second-generation games, HMs can be used repeatedly, so you do not have to panic about “wasting” Flash on one Pokémon. However, HM moves are sticky. Once a Pokémon learns Flash, it cannot simply forget the move through the normal move-learning process. You will need the Move Deleter later in Blackthorn City if you want to remove it cleanly.

That is why many players teach Flash to a utility Pokémon instead of a main battle star. Nobody wants their prized Typhlosion carrying around Flash like an old flashlight from the junk drawer. It can be useful in battle in a pinch, but its main purpose is exploration.

How to Get Flash in Pokémon Silver: 6 Steps

Step 1: Travel to Violet City

Your journey to HM05 Flash begins in Violet City, one of the earliest major towns in Johto. After leaving New Bark Town, passing through Cherrygrove City, and moving along Routes 30 and 31, you will eventually arrive in Violet City. This city is home to the first Gym Leader, Falkner, and the famous Sprout Tower.

Before charging into the tower, visit the Pokémon Center. Heal your team, organize your party, and stock up on a few basic items if needed. Sprout Tower is not brutally difficult, but it can annoy unprepared players, especially at night when Gastly can appear. If your team relies too much on Normal-type attacks, those ghostly little pranksters can turn your confident march into a comedy routine.

Step 2: Enter Sprout Tower

Sprout Tower is located in Violet City. It is a three-story wooden tower built around a swaying central pillar. In the game’s lore, that pillar is said to have come from a massive Bellsprout. Yes, Johto architecture apparently includes “giant plant spine” as a design category. Charming? Definitely. Building-code compliant? Let’s not ask too many questions.

Inside Sprout Tower, you will battle several Sages who mostly use Bellsprout. Because Bellsprout is a Grass/Poison-type Pokémon, Fire-, Flying-, Psychic-, and Ice-type attacks work well. Early in the game, your best practical options are often Cyndaquil, Pidgey, Spearow, Hoothoot, or other Pokémon with useful non-Normal attacks.

If you chose Cyndaquil as your starter, Sprout Tower is basically a warm-up snack. Ember will make quick work of the Bellsprout lineups. If you chose Chikorita, you may have a slower time because Grass-type attacks are not ideal here. Totodile players should still be fine, but having a Flying-type teammate can make the climb much smoother.

Step 3: Climb Through the Tower and Battle the Sages

As you move through Sprout Tower, climb the ladders and battle each Sage blocking your path. The tower is simple compared with later caves and dungeons, but it still has a few items worth grabbing. In Pokémon Silver, you can find items such as Parlyz Heal, X Defend, Potion, and Escape Rope while exploring.

Most trainers here use low-level Bellsprout. Do not underestimate them completely, though. Bellsprout can chip away at your team if you arrive under-leveled or keep switching in Pokémon that do not match up well. A level 8 or higher team is generally comfortable, and a level 10 or 11 Flying- or Fire-type Pokémon can make the tower feel like a sightseeing tour with occasional leaf-based interruptions.

At night, wild Gastly can appear on the upper floors. This can be a blessing or a nuisance. Gastly is a fun early Ghost/Poison-type Pokémon, but it can be tricky to hit if your team depends on Normal-type moves. If you want to catch one, bring Poké Balls and a Pokémon with a move that can damage Ghost-types.

Step 4: Reach the Elder at the Top

At the top of Sprout Tower, you will meet Elder Li. Before you battle him, you will see your rival, Silver, leaving after defeating the Elder. Your rival is as warm and friendly as a locked door, so naturally he exits with his usual dramatic attitude.

Elder Li is tougher than the Sages below him. His team includes Bellsprout and Hoothoot, and that Hoothoot can surprise players who expected the whole tower to be one long salad bar. If your strategy is only “burn the plants,” Hoothoot may slow you down. Rock-type Pokémon like Geodude or Onix can help, while Electric-type attacks from Mareep are also useful if you have one.

Still, this battle is very manageable if your Pokémon are properly leveled. Use type advantages, keep a Potion ready if needed, and do not let Hoothoot chip your team down while you mash the A button and pretend strategy is optional. Johto rewards calm trainers, not button-mashing gremlins.

Step 5: Defeat Elder Li and Receive HM05 Flash

After you defeat Elder Li, he gives you HM05 Flash. Congratulations: you now own the official cave-lighting solution of early Johto. No batteries required, no monthly subscription, and no questionable smartphone app asking for location access.

At this point, HM05 will appear in your bag. You can use it to teach Flash to a compatible Pokémon. Because HMs are reusable, you can teach Flash to more than one Pokémon if you really want to. However, most players only need one Flash user in the party.

Before leaving Sprout Tower, grab the Escape Rope near the top floor if you have not already. You can use it to exit the tower quickly. Otherwise, you can simply climb back down the ladders and leave the old-fashioned way.

Step 6: Beat Falkner for the Zephyr Badge

Here is the part many beginners miss: getting HM05 Flash is not the same as being able to use Flash outside battle. In Pokémon Silver, you need the Zephyr Badge from Falkner, the Violet City Gym Leader, to use Flash as a field move.

Falkner specializes in Flying-type Pokémon. His team is not large, but his Pidgeotto can be intimidating for new players. Mareep is excellent here because Electric-type attacks work well against Flying-types. Geodude can also help because it resists Flying-type moves and can hit back with Rock-type attacks. If you only have Chikorita, expect a tougher fight, because Grass-type Pokémon do not love being pecked into emotional damage.

After you defeat Falkner, you receive the Zephyr Badge and TM31 Mud-Slap. More importantly for this guide, the Zephyr Badge allows Flash to be used outside battle. Once you teach Flash to a compatible Pokémon, you can enter a dark cave, open your party menu, select the Pokémon that knows Flash, and use the move to brighten the area.

Best Pokémon to Teach Flash in Pokémon Silver

The best Pokémon to teach Flash is usually one you do not mind using for utility. Since Flash is not a powerful attack, it is often better to avoid teaching it to your main damage dealer. You only get four move slots per Pokémon, and wasting one on Flash can feel painful later.

Good Early Flash Users

Bellsprout is a popular choice because it is available early and can also learn Cut later, making it a handy utility Pokémon. Hoothoot is another practical choice, especially if you caught one at night. Mareep, available on Route 32 in Pokémon Silver, can also learn Flash and is already useful against Falkner. Some players also use Gastly, though it depends on your team plans.

If you care about long-term team building, teach Flash to a Pokémon you are comfortable keeping as a helper rather than a core battler. If you are playing casually, do not overthink it. A slightly imperfect move set will not cause Professor Oak to appear from the bushes and confiscate your Pokédex.

Where Flash Is Useful After You Get It

Flash helps illuminate dark caves. The first place many players consider using it is Dark Cave near Violet City. You do not need to fully explore Dark Cave immediately, but Flash makes it much easier if you decide to go in.

Later in the game, Flash becomes helpful in several dark areas, including Mt. Mortar, Whirl Islands, Rock Tunnel in Kanto, and Mt. Silver near the end of the adventure. Some veteran players memorize cave layouts and skip Flash entirely, but for normal humans who do not have Johto cartography tattooed on their brain, Flash is a comfort move.

Common Mistakes When Getting Flash

Trying to Use Flash Before Beating Falkner

The most common mistake is defeating Elder Li, receiving HM05, teaching it to a Pokémon, and then wondering why it will not light up caves. The missing piece is the Zephyr Badge. Beat Falkner first, then use Flash outside battle.

Teaching Flash to a Main Attacker Too Early

Another mistake is teaching Flash to a starter Pokémon without thinking. It is not the end of the world, but it can be annoying later when you want a better move in that slot. Since HM moves require the Move Deleter to remove, choose carefully.

Entering Sprout Tower at Night With Only Normal Moves

At night, Gastly can appear. Normal-type moves do not affect Ghost-type Pokémon, so bring at least one Pokémon with a move that can hit Gastly. Otherwise, your brave adventure may turn into a slapstick routine where everyone misses the ghost and nobody learns anything except regret.

Extra Tips for Sprout Tower

Sprout Tower is a great early training spot. The Sages provide useful experience, and the wild encounters can help round out your team. If you are preparing for Falkner, consider catching Mareep on Route 32 before the Gym battle. It is one of the most beginner-friendly answers to Flying-types in the early game.

If you want Gastly, visit Sprout Tower at night. Gastly can be a fun addition thanks to its immunities and status moves, but catching it may require patience. Bring extra Poké Balls and do not rely on Normal-type attacks.

Also, pick up the Escape Rope near Elder Li. It is easy to miss if you are focused only on getting Flash, but it saves time when leaving the tower. In classic Pokémon fashion, half the adventure is battling monsters, and the other half is realizing you forgot to pick up the free item sitting five steps away.

Is Flash Required to Beat Pokémon Silver?

Strictly speaking, Flash is not always required to finish Pokémon Silver. Many dark caves can be crossed without it if you know the layout or are willing to stumble around. However, Flash makes exploration much easier and less frustrating. For a first playthrough, getting Flash is strongly recommended.

Think of Flash as a quality-of-life tool. It does not hit hard in battle, and it will not win the Pokémon League for you, but it saves time, reduces confusion, and makes caves feel less like punishment for forgetting a map.

Player Experience: What Getting Flash Feels Like in Pokémon Silver

Getting Flash in Pokémon Silver is one of those early-game moments that quietly teaches you how Johto works. The game does not simply hand you every tool at the front desk like a hotel keycard. Instead, it nudges you into a small side adventure: reach Violet City, investigate the mysterious tower, battle monks with an alarming devotion to Bellsprout, meet your rival, defeat the Elder, then prove yourself at the Gym. By the end, you have not just collected an HM. You have learned how badges, field moves, optional dungeons, and team planning all fit together.

For many players, Sprout Tower is also the first place where team balance starts to matter. If you picked Cyndaquil, you may feel unstoppable as Ember clears one Bellsprout after another. If you picked Chikorita, the tower is a gentle warning that Johto will not always roll out a leafy green carpet for you. If you caught a Pidgey, Spearow, Mareep, or Gastly, you begin to see how even low-level Pokémon can solve specific problems.

There is also a memorable atmosphere to the whole sequence. Violet City feels calm, almost sleepy, and then Sprout Tower adds this strange spiritual energy. The swaying pillar, the quiet Sages, the repeated Bellsprout battles, and the sudden appearance of your rival make the place feel more important than a simple item location. It is not just “go upstairs and grab HM05.” It is a mini lesson in patience, respect, and preparation. Also, yes, it is a lesson in not underestimating a level 10 Hoothoot.

Using Flash for the first time can feel oddly satisfying. You enter a dark cave, select the move, and the screen opens up. Suddenly, the cave is no longer a black maze of guesswork. You can see paths, walls, ladders, rocks, and trainers. It is not glamorous, but it is practical. In a game where exploration is half the fun, that little burst of light changes the mood immediately.

Modern Pokémon games have mostly moved away from old-school HMs, so returning to Pokémon Silver can feel like stepping into a different design philosophy. Back then, your party was not just a battle squad. It was also your toolkit. One Pokémon cut trees, another lit caves, another surfed across water, and another pushed boulders. Sometimes that system was clunky, but it also made your team feel connected to the world. Flash is a perfect example: not powerful, not flashy in the modern sense, but useful enough that you remember it decades later.

The smartest approach is to treat Flash as an exploration move, not a battle move. Teach it to a helper Pokémon, keep that Pokémon available when you plan to explore caves, and save your main attackers’ move slots for stronger options. That simple habit will make your Pokémon Silver playthrough smoother from Violet City all the way to the late-game climb toward Mt. Silver.

Conclusion

To get Flash in Pokémon Silver, go to Violet City, enter Sprout Tower, climb to the top, defeat Elder Li, and receive HM05 Flash. Then defeat Falkner at the Violet City Gym to earn the Zephyr Badge, which allows Flash to work outside battle. Teach it to a compatible Pokémon, and you will be ready to light up dark caves across Johto and beyond.

Flash may not be the most exciting move in battle, but it is one of the most useful exploration tools in the classic second-generation games. Whether you are playing for nostalgia, building a careful team, or simply trying not to get lost in Dark Cave for the next three business days, HM05 Flash is worth grabbing early.
