Pokémon Infinite Fusion does much more with Gym Leaders than simply copy the original Kanto adventure. You begin with familiar Kanto leaders such as Brock, Misty and Lt. Surge, but their battles are built around fused Pokémon that can completely change the matchup you expect.
After becoming Champion, the Gym challenge continues. Eight more badges can be collected through Johto and parts of the Sevii Islands, giving Pokémon Infinite Fusion a total of 16 major Gym Leader battles in its main progression.
This guide covers the Pokemon Infinite Fusion Gym Leaders in order, their locations, specialties, badges, important Gym requirements and practical strategies for defeating them.
Pokemon Infinite Fusion Gym Leaders in Order
Here is the quickest way to see the full Gym progression.
| # | Gym Leader | Location | Classic Specialty | Badge |
|---|---|---|---|---|
| 1 | Brock | Pewter City | Rock | Boulder Badge |
| 2 | Misty | Cerulean City | Water | Cascade Badge |
| 3 | Lt. Surge | Vermillion City | Electric | Thunder Badge |
| 4 | Erika | Celadon City | Grass | Rainbow Badge |
| 5 | Koga | Fuchsia City | Poison | Soul Badge |
| 6 | Sabrina | Saffron City | Psychic | Marsh Badge |
| 7 | Blaine | Cinnabar Island | Fire | Volcano Badge |
| 8 | Giovanni | Viridian City | Ground | Earth Badge |
| 9 | Whitney | Goldenrod City | Normal | Plain Badge |
| 10 | Kurt | Azalea Town | Bug | Hive Badge |
| 11 | Falkner | Violet City | Flying | Zephyr Badge |
| 12 | Clair | Blackthorn City | Dragon | Rising Badge |
| 13 | Chuck | Boon Island | Fighting | Storm Badge |
| 14 | Pryce | Mahogany Town | Ice | Glacier Badge |
| 15 | Morty | Ecruteak City | Ghost | Fog Badge |
| 16 | Jasmine | Bond Bridge / Sevii Islands | Steel | Mineral Badge |
The first eight badges form the Kanto Gym challenge. The additional eight are part of the expanded postgame adventure and ultimately help unlock further endgame progression, including Mt. Silver.
How Gym Battles Work in Pokemon Infinite Fusion
The fusion system makes these battles less predictable than normal Pokémon Gym battles.
A leader may specialize in Rock, Water or another familiar type, but a fused Pokémon can have a second type that changes its weaknesses and resistances. That means bringing six Pokémon that all rely on one supposedly super-effective type is usually a bad strategy.
Early Gym battles can also restrict the number of Pokémon you are allowed to use based on the size of the Gym Leader’s party. This makes team selection particularly important in the Kanto portion of the game.
A better approach is to prepare:
- one strong counter to the leader’s main type;
- a second Pokémon covering unexpected fusion typings;
- status or setup moves;
- healing and status-curing items;
- Pokémon close to the expected Gym level.
Most importantly, inspect the actual typing of a fusion instead of assuming that both of its base Pokémon work exactly as they normally would.
1. Brock – Pewter City Gym
Type specialty: Rock
Badge: Boulder Badge
Location: Pewter City
Reward includes: TM39 and the Boulder Badge
Brock is the first Pokemon Infinite Fusion Gym Leader and the first real test of whether you understand fusion matchups.
His Classic battle still revolves around Rock-oriented Pokémon, but his team is not simply the Geodude and Onix lineup players may remember from Pokémon Red and Blue.
For example, current Gym data includes unusual fusions such as Tangela/Omanyte, demonstrating why blindly choosing a Water or Grass attack based only on Brock’s traditional specialty can backfire.
How to Beat Brock
Water, Grass and Fighting coverage remains useful, but examine both parts of each fusion before attacking.
Special attackers can also be valuable because many Rock-oriented Pokémon have better physical Defense than Special Defense.
Avoid building your entire strategy around a single Water Pokémon. A Grass secondary type or unusual ability can turn what looked like an easy matchup into a problem.
Brock Gym Tip
You do not need a full six-Pokémon squad to win. Focus on bringing your strongest available counters and make sure they are healthy before speaking to Brock.
2. Misty – Cerulean City Gym
Type specialty: Water
Badge: Cascade Badge
Location: Cerulean City
Reward includes: TM55 and the Cascade Badge
Misty runs the Cerulean City Gym and is the second major Gym challenge.
Her team demonstrates Infinite Fusion’s biggest battle twist very well. Current Classic data includes Jigglypuff/Goldeen, which combines Normal and Water characteristics rather than acting like a conventional pure Water Pokémon.
How to Beat Misty
Electric and Grass attacks are obvious choices, but do not assume every member of her party will share exactly the same weaknesses.
Bring:
- Electric coverage for standard Water matchups;
- Grass coverage as a second option;
- a Pokémon capable of taking special attacks;
- status recovery in case her team slows your momentum.
Misty becomes much easier when you can attack different fusion combinations instead of relying on one counter.
3. Lt. Surge – Vermillion City Gym
Type specialty: Electric
Badge: Thunder Badge
Location: Vermillion City
Reward includes: TM73 and the Thunder Badge
Lt. Surge is the third Gym Leader.
The obvious answer to an Electric specialist is a Ground Pokémon, but Infinite Fusion deliberately makes that strategy less automatic.
Current Gym data includes combinations such as Voltorb/Krabby and Electabuzz/Hitmonchan, meaning his fusions can bring Water or Fighting characteristics and wider move coverage into the battle.
How to Beat Lt. Surge
Ground attacks are still extremely valuable.
However:
- avoid depending on only one Ground Pokémon;
- prepare for Water coverage;
- watch for Fighting attacks;
- use faster attackers where possible;
- do not underestimate priority moves.
A Ground fusion with a useful secondary type can make an excellent counter.
4. Erika – Celadon City Gym
Type specialty: Grass
Badge: Rainbow Badge
Location: Celadon City
Erika cannot simply be challenged the moment you reach Celadon.
In Infinite Fusion’s story, she becomes involved with the Team Rocket situation. The Celadon Gym becomes part of your progression after the relevant Rocket events and Giovanni encounter.
How to Beat Erika
Fire is the most obvious attacking option, but Flying, Ice, Bug and Poison coverage can also help depending on the fusion.
Grass teams often rely on more than raw damage. Expect possibilities such as:
- status conditions;
- recovery;
- defensive switching;
- setup moves;
- secondary typings that neutralize Fire.
A fast Fire or Flying attacker is helpful, but carry a Full Heal or similar status recovery instead of assuming you can sweep without interruption.
Before challenging a Gym Leader, use the Pokemon Team Builder to prepare your party and the Pokemon Type Calculator to identify useful matchups. The Pokemon Infinite Fusion Walkthrough explains progression between gyms, while the Pokemon Infinite Fusion Map can help you find important locations.
5. Koga – Fuchsia City Gym
Type specialty: Poison
Badge: Soul Badge
Location: Fuchsia City
Reward includes: TM06
Koga is found in Fuchsia City.
The current game data includes Poison-centered fusions such as Venomoth/Grimer, reinforcing his Poison theme while adding secondary typing and expanded movesets. Defeating Koga also gives the Soul Badge, which is tied to further field progression.
How to Beat Koga
Psychic and Ground attacks are normally excellent against Poison, but secondary typings matter considerably here.
Koga’s style can also involve:
- poisoning your team;
- disabling attacks;
- unusual coverage moves;
- bulky Poison fusions.
Bring status healing.
A Pokémon that can hit hard without relying on Toxic-style damage is particularly useful because many Poison Pokémon naturally handle poison-based strategies well.

6. Sabrina – Saffron City Gym
Type specialty: Psychic
Badge: Marsh Badge
Location: Saffron City
Reward includes: TM03
Sabrina runs Saffron City’s Psychic Gym.
Before treating the Gym as your next objective, you will need to deal with the Team Rocket situation surrounding Silph Co. Saffron itself is an important story hub rather than just another Gym stop.
How to Beat Sabrina
Dark, Ghost and Bug moves provide important coverage against Psychic Pokémon.
The bigger danger is Sabrina’s offensive power. Psychic-oriented fusions can hit extremely hard on the special side.
Try to:
- outspeed fragile Psychic attackers;
- use strong physical moves;
- avoid leaving Poison- or Fighting-heavy Pokémon exposed;
- carry Dark coverage on more than one team member.
Bulky Dark fusions can be especially useful.
7. Blaine – Cinnabar Island Gym
Type specialty: Fire
Badge: Volcano Badge
Location: Cinnabar Island
Reward includes: TM38
Blaine is the seventh Kanto Gym Leader.
You cannot immediately walk into his Gym and challenge him. Progress through the Pokémon Mansion is required first.
His current Classic lineup demonstrates why fusion coverage matters. Examples include Gloom/Rapidash and Ninetales/Arcanine. The former is particularly interesting because combining Grass and Fire changes how you should approach what looks like a straightforward Fire Gym.
How to Beat Blaine
Water, Ground and Rock moves remain your main attacking tools.
Be careful with Water-only strategies, however. Grass secondary typings and coverage moves can punish them.
A strong Ground attacker is often safer because it can pressure Fire Pokémon without automatically exposing itself to the same weaknesses as a Water type.
Also watch for Sunny Day, which can:
- strengthen Fire attacks;
- weaken Water attacks;
- enable Solar Beam.
8. Giovanni – Viridian City Gym
Type specialty: Ground
Badge: Earth Badge
Location: Viridian City
Reward includes: TM26
Giovanni is the final Kanto Gym Leader.
His Gym represents the conclusion of the eight-badge Kanto journey before the Pokémon League.
Current game data includes powerful combinations such as Rhyperior/Lapras, showing how dramatically a fusion can change a traditional Ground matchup.
How to Beat Giovanni
Water, Grass and Ice are excellent starting points against Ground Pokémon.
But against fused opponents:
- check for Water secondary typing;
- avoid assuming every Ground fusion is weak to Ice;
- keep a strong special attacker available;
- expect substantially stronger stats than in the early Gyms.
At this point your team should be built around coverage rather than a single Gym counter.
What Happens After the First 8 Gym Leaders?
Defeating Giovanni gives you your eighth Kanto badge and puts you on the path toward the Pokémon League.
However, the Gym challenge is not finished permanently.
After defeating the Elite Four, Pokémon Infinite Fusion opens a much larger postgame involving eight additional badges across Johto and the Sevii Islands.
These are not simply copies of Pokémon Gold and Silver’s progression. Infinite Fusion changes several locations and even replaces one familiar leader.
9. Whitney – Goldenrod City Gym
Type specialty: Normal
Badge: Plain Badge
Location: Goldenrod City
Reward includes: TM98
Whitney is the first additional Gym Leader available in the postgame.
The Goldenrod Gym becomes accessible after the Elite Four, and its puzzle asks you to count Pokémon correctly.
Her current Classic lineup begins around the mid-50s and includes fusions such as Lickitung/Granbull.
How to Beat Whitney
Fighting attacks remain the natural answer to Normal Pokémon, but Fairy, Electric and other secondary typings can complicate that plan.
Do not send one Fighting Pokémon into every matchup without checking the fusion.
Whitney’s Pokémon can also be fairly bulky, so powerful neutral attacks may sometimes be safer than forcing a questionable super-effective matchup.
10. Kurt – Azalea Town Gym
Type specialty: Bug
Badge: Hive Badge
Location: Azalea Town
Reward includes: TM99
This is one of the most commonly reported incorrectly by generic Pokémon guides.
Kurt—not Bugsy—is the Azalea Gym Leader in Pokémon Infinite Fusion.
When you first arrive, Azalea is dealing with flooding. After helping with the situation, you can enter the Gym.
The Gym uses a web-based memory puzzle where the player interacts with the correct webs in sequence. The pattern can change after leaving and re-entering.
Current Classic data includes Bug fusions such as Beedrill/Ariados and Forretress/Cloyster.
How to Beat Kurt
Fire, Flying and Rock are your main Bug counters.
Fire is particularly valuable, but secondary types such as Water or Ice can change individual matchups.
Focus on identifying each fusion before selecting your move.
11. Falkner – Violet City Gym
Type specialty: Flying
Badge: Zephyr Badge
Location: Violet City
Reward includes: TM100 Defog
Falkner controls the Violet City Gym.
Instead of a simple trainer gauntlet, his Gym uses a wind puzzle. You need to move across raised platforms while using timing and obstacles to avoid being blown off course.
Current Classic data includes Xatu/Noctowl, keeping Falkner’s Flying theme while introducing more complicated Psychic/Flying interactions.
How to Beat Falkner
Electric, Ice and Rock attacks are generally best.
Electric is particularly reliable against many Flying combinations, but Ground secondary types can create immunities, so maintain more than one attacking option.
Stealth Rock and other Rock-based damage can also perform well against teams containing several Flying Pokémon.
12. Clair – Blackthorn City Gym
Type specialty: Dragon
Badge: Rising Badge
Location: Blackthorn City
Reward includes: TM101
Clair is the Dragon specialist in Blackthorn City.
Her Gym uses a boulder puzzle inspired by the classic Johto games: push boulders into the correct holes to create a path forward.
Current Classic data includes combinations such as Feraligatr/Gyarados, proving that a Dragon-specialist battle can still contain fusion combinations requiring very different counters.
How to Beat Clair
Ice, Fairy and Dragon coverage are important, but do not automatically select a Dragon move just because you are fighting Clair.
Fairy Pokémon provide the important benefit of immunity to Dragon attacks, although secondary typings and coverage moves can still threaten them.
Ice coverage on a fast non-Ice Pokémon can often be safer than bringing an entire Ice-focused team.
13. Chuck – Boon Island
Type specialty: Fighting
Badge: Storm Badge
Location: Boon Island
Additional reward: Navel Ticket
Chuck is one of the best examples of Infinite Fusion changing the original Johto structure.
You do not challenge him in a conventional Cianwood Gym.
Chuck is found on Boon Island in the Sevii Islands, where he is effectively on vacation. After finding him, you can challenge him directly.
His team includes hard-hitting Fighting fusions such as Kabutops/Machamp and Blaziken/Infernape.
How to Beat Chuck
Psychic, Flying and Fairy attacks are your best starting point.
Be careful with Flying Pokémon, however, because Rock secondary types and Rock coverage can turn an expected counter into a liability.
Fast Psychic attackers are often particularly effective if they can avoid taking a physical hit.
14. Pryce – Mahogany Town Gym
Type specialty: Ice
Badge: Glacier Badge
Location: Mahogany Town
Reward includes: TM79
Pryce runs Mahogany Town’s Ice Gym.
His puzzle is far more memorable than simply sliding across an empty ice floor. You must move a Poké Ball around the hockey-style arena and get it into the goal, using positioning and the trainers on the ice to control its path.
How to Beat Pryce
Fire, Fighting, Rock and Steel attacks all work well against Ice.
The danger is assuming every Ice fusion shares the same weakness. Water/Ice combinations, Ground secondary types and unusual abilities can force you to change plans.
Steel is often a useful defensive choice because it resists Ice while also providing super-effective damage.
15. Morty – Ecruteak City Gym
Type specialty: Ghost
Badge: Fog Badge
Location: Ecruteak City
Morty’s Gym is initially unavailable because Morty is away training.
You first need to find him in the Burned Tower. Reaching him is also tied to progression gained through the Sevii Island portion of the postgame. Once you speak to him, he returns to the Gym.
The Gym itself uses disappearing and reappearing skull platforms to create a dark maze.
How to Beat Morty
Dark and Ghost attacks are the obvious choices.
However, Morty’s fusions are dangerous because Ghost combinations can produce unusual immunities.
One especially notorious type of matchup involves Shedinja-based fusion mechanics, so carrying broad move coverage rather than only one attacking type is very useful.
Priority moves can also help against faster Ghost attackers.
16. Jasmine – Final Gym Badge
Type specialty: Steel
Badge: Mineral Badge
Battle location: Bond Bridge area in the Sevii Islands
Jasmine is another leader who does not simply wait inside her original Johto Gym.
You encounter her around the Bond Bridge/Berry Forest portion of the Sevii Islands. After helping rescue her nephew and the other children in Berry Forest, Jasmine accepts your challenge on the bridge.
Defeating her awards the Mineral Badge, completing the full 16-badge Gym challenge.
How to Beat Jasmine
Fire, Fighting and Ground attacks are the traditional Steel counters.
Ground is particularly valuable, but remember that a Steel/Flying fusion can be immune to Ground.
A balanced combination of Fire and Fighting coverage gives you a strong answer to most of the team without depending on one weakness.
Jasmine is one of the last Gym-level tests of the game, so expect powerful evolved fusions rather than the relatively simple combinations seen in early Kanto.
Kanto vs Johto Gym Leaders
The two halves of the Gym challenge feel very different.
Kanto Gyms
The Kanto section is part of the main story and gradually teaches you how to deal with fusion mechanics.
You battle:
Brock → Misty → Lt. Surge → Erika → Koga → Sabrina → Blaine → Giovanni
After collecting all eight badges, you continue toward the Pokémon League.
Postgame Gyms
The second set becomes available as part of the expanded postgame.
The progression used by Infinite Fusion is:
Whitney → Kurt → Falkner → Clair → Chuck → Pryce → Morty → Jasmine
These later battles use much stronger Pokémon and expect you to understand abilities, held items, secondary typings and fusion stat combinations.
Classic vs Remix Gym Leaders
One reason different Pokemon Infinite Fusion Gym Leader guides appear to contradict each other is that Classic Mode and Remix Mode do not use exactly the same Gym specialties.
In Remix Mode, the Kanto specialties change to:
| Leader | Classic | Remix |
|---|---|---|
| Brock | Rock | Steel |
| Misty | Water | Ice |
| Lt. Surge | Electric | Fighting |
| Erika | Grass | Bug |
| Koga | Poison | Dark |
| Sabrina | Psychic | Fairy |
| Blaine | Fire | Psychic |
| Giovanni | Ground | Normal |
The Johto/postgame specialties also change:
| Leader | Classic | Remix |
|---|---|---|
| Whitney | Normal | Fairy |
| Kurt | Bug | Grass |
| Falkner | Flying | Bug |
| Clair | Dragon | Dragon |
| Chuck | Fighting | Ground |
| Pryce | Ice | Ghost |
| Morty | Ghost | Fire |
| Jasmine | Steel | Electric |
So if Brock is using a Steel-focused team rather than the Rock-oriented lineup described earlier, you are probably playing Remix Mode, not encountering incorrect game data.
What About Randomized Mode?
Randomized Mode changes the situation even further.
Depending on your settings, Gym trainers and Gym Leaders can receive randomized Pokémon. Gym types themselves can also be randomized.
If Gym-type randomization is enabled, talk to the man near the entrance of the Gym. He can tell you which type that Gym has been assigned.
Because randomized Gym teams can change, a fixed online list cannot reliably tell you exactly which Pokémon you will face in that mode.
Pokemon Infinite Fusion Gym Leader Rematches
Gym Leaders do not disappear forever after you defeat them.
During the later game, leaders can be found at specific locations and times. After speaking with them, they can be invited for rematches at the Vermillion City Arena.
Most Kanto leaders become available for this system after the Elite Four, while Giovanni and the Johto leaders require further endgame progression.
Gym Leader Rematch Locations
| Leader | Where to Find Them | Time |
|---|---|---|
| Brock | Route 3 | Day |
| Misty | Cerulean Cape | Morning |
| Lt. Surge | Route 10 near Power Plant | Day |
| Erika | National Park | Day |
| Koga | Pokémon League Gate | Evening |
| Sabrina | Goldenrod City | Night |
| Blaine | Seafoam Islands | Day |
| Giovanni | Crimson City | Evening |
| Whitney | Violet City | Evening |
| Kurt | Viridian Forest | Morning |
| Falkner | Celadon Department Store Roof | Morning |
| Clair | Dragon’s Den | Night |
| Morty | Lavender Town | Night |
| Pryce | Ice Mountains | Day |
| Chuck | Saffron City near the Fighting Dojo | Afternoon |
| Jasmine | Chrono Island | Morning |
The current rematch system defines the in-game periods roughly as:
- Morning: 5 AM–10 AM
- Day: 10 AM–2 PM
- Afternoon: 2 PM–5 PM
- Evening: 5 PM–8 PM
- Night: 8 PM–5 AM
Rematch teams are considerably stronger and use full high-level fusion teams, making them useful challenges for an endgame squad.
Best General Strategy for Every Gym
There is no single fusion that automatically beats every Gym, but a few principles work throughout the game.
Check Both Types
Never attack based only on the first Pokémon you recognize.
A Water/Flying fusion, for example, behaves very differently from a Water/Ground fusion.
Build Coverage Instead of Six Counters
It is usually better to have six strong Pokémon covering many attacking types than six Pokémon designed specifically for one Gym.
Useful coverage includes:
- Ground
- Ice
- Fairy
- Fighting
- Electric
- Dark
- Fire
Together these answer a large portion of the Gym roster.
Pay Attention to Abilities
Fusion abilities can completely change a matchup.
An ability may:
- remove a weakness;
- grant an immunity;
- increase damage;
- activate weather;
- punish physical contact.
Type advantage alone therefore does not guarantee victory.
Carry Status Recovery
Later leaders make much greater use of status, setup and strategic moves.
Keep Full Heals or equivalent recovery available rather than using your entire inventory on HP restoration.
Do Not Ignore Held Items
Later Gym Pokémon can use competitive-style held items.
If an opponent survives unexpectedly or deals far more damage than expected, its item may be the reason.
Frequently Asked Questions
How many Gym Leaders are in Pokemon Infinite Fusion?
The main Classic progression contains 16 Gym Leader battles: eight Kanto badges before the Pokémon League and eight additional postgame badges associated with Johto and the Sevii Islands.
Who is the first Gym Leader in Pokemon Infinite Fusion?
Brock in Pewter City is the first Gym Leader.
Who is the last Kanto Gym Leader?
Giovanni in Viridian City is the eighth and final Kanto Gym Leader.
Who is the ninth Gym Leader?
Whitney in Goldenrod City begins the additional postgame Gym challenge after the Elite Four.
Is Bugsy a Gym Leader in Pokemon Infinite Fusion?
Not in the main Infinite Fusion Gym progression described here. Kurt is the Azalea Town Gym Leader and awards the Hive Badge.
Bugsy can still appear in the game, which is one reason players sometimes confuse the Infinite Fusion progression with standard Pokémon Gold and Silver.
Where is Chuck?
Chuck is found on Boon Island in the Sevii Islands rather than waiting in a traditional Cianwood Gym. Defeating him awards the Storm Badge and the Navel Ticket.
Where is Jasmine?
Jasmine’s badge battle takes place during the Sevii Island progression around Bond Bridge/Berry Forest. Help with the missing children first, then she will accept your challenge.
Why are my Gym Leader teams different from this guide?
Check your game mode.
Remix Mode changes Gym specialties and teams. Randomized Mode can randomize Gym Pokémon and even Gym types. Hard and Expert settings can also change difficulty, levels or team composition.
Game updates can additionally rebalance specific teams.
Do Gym Leaders have fused Pokémon?
Yes. Fusion teams are one of the central differences between Infinite Fusion and the original Pokémon games.
A Gym may have a recognizable specialty, but its Pokémon can combine that specialty with secondary typings, abilities and moves from completely different species.
Can Gym Leaders be rematched?
Yes. Gym Leaders can later be found throughout the world at specific times and invited to the Vermillion City Arena for stronger rematch battles.
Final Tips
The Pokemon Infinite Fusion Gym Leaders are designed to punish players who treat every battle like a standard Pokémon game.
Knowing that Brock uses Rock or Misty uses Water is useful, but it is only the starting point. The real challenge is understanding what each fusion does to that familiar matchup.
Build a team with varied coverage, inspect both types before choosing an attack, pay attention to abilities and held items, and keep enough flexibility to change strategy during battle.
Once Giovanni falls, do not assume the Gym challenge is over either. Whitney begins a second run of eight badges that takes you through Johto and the Sevii Islands, eventually ending with Jasmine and the complete 16-badge challenge.
