Clemont — Lumiose City Gym (Prism Tower)

Electric-type · Inventor + Pokémon-loving kid · Specialty: status moves + special attackers

Gym puzzle: A 6-floor elevator quiz. On each of floors 2–5, Clemont's little sister Bonnie shows you a Pokémon silhouette and gives you three choices (left, middle, right). You pick the elevator with the correct answer. If you pick the right elevator, you skip extra trainer battles. If you pick wrong, you fight more trainers (but earn more XP). You can deliberately pick wrong to fight all 12 possible trainers for grinding.

Clemont's team

Pokémon	Lv	Type	Notes
Emolga	35	Electric/Flying	Static. Volt Switch + Aerial Ace + Light Screen + Quick Attack. ★ Immune to Ground via Flying — your usual Electric counter doesn't work here. Bring Rock/Ice/Electric.
Magneton	35	Electric/Steel	Magnet Pull (traps Steel switches). Tri Attack + Magnet Bomb + Spark + Mirror Shot. 4× weak to Ground — Garchomp/Diggersby/Nidoking destroy it.
Heliolisk	37	Electric/Normal	★ Her ace. Dry Skin (heals 1/8 HP per turn in sun, hurts in rain). Thunderbolt + Bulldoze + Quick Attack + Parabolic Charge. Fast and bulky; only weak to Fighting/Ground.

The 4-floor elevator quiz (with answers)

★ Easy mode: Answering all 4 quizzes correctly takes you straight to Clemont with only 4 trainer fights. The answers (per Bulbapedia and Thonky):

Floor 2 — silhouette of Pikachu

Door 3 (right) Correct

Floor 3 — silhouette of Fletchling

Door 1 (left) Correct

Floor 4 — silhouette of Panpour

Door 3 (right) Correct

Floor 5 — silhouette of Vivillon

Door 2 (middle) Correct

Gym trainers (sample of the 12 possible)

Floor	Trainer	Door	Roster
2F	Schoolboy Arno	Wrong	Pachirisu Lv 34
2F	Schoolboy Sherlock	Wrong	Stunfisk Lv 34
3F	Rising Star Estel	Correct	Raichu Lv 35
3F	Rising Star Nelly	Wrong	Magneton Lv 35
3F	Rising Star Helen	Wrong	Manectric Lv 35
4F	Various Punks / Engineers	Mixed	Lv 35–36 Electric mons (Electrode, Voltorb, Plusle, Minun, Joltik, Galvantula)
5F	Higher-tier trainers	Mixed	Lv 36 Electric mons including Luxio/Luxray, Electabuzz

Source caveat: The full 12-trainer roster of Clemont's gym is not fully enumerated in the search snippets I could verify. The five confirmed trainers above (Arno, Sherlock, Estel, Nelly, Helen) are documented; the floor 4–5 trainers are described but not all named. If you take the "wrong" paths to grind, expect Lv 35–36 Electric Pokémon throughout.

Threat assessment

Pokémon	Threat	Why
Emolga	Medium	★ Tricky — Flying typing means your Ground-type counters fail. Bring Rock (Tyrantrum, Aurorus, Aerodactyl), Ice (Lapras, Aurorus, Mareep evos that learn Ice), or strong Electric (Heliolisk mirror).
Magneton	Low	4× weak to Ground. Garchomp/Diggersby/Nidoking one-shots with Earthquake. The only catch: Magnet Pull traps your Steel switches.
Heliolisk	High	★ Ace. Dry Skin auto-heals in sun (Mega Charizard Y triggers this!). Parabolic Charge heals it as it attacks. Bring Fighting (Mega Lucario's Power-Up Punch ramps fast) or Ground (Garchomp's Earthquake one-shots).

Recommended counters (in order)

Counter	Why	Recommended moves
Garchomp (Gible evo, if caught on Route 13)	★ ★ ★ Ground STAB Earthquake one-shots Magneton, severely damages Heliolisk, and Garchomp's Dragon Claw chips Emolga. Best counter in the entire game.	Earthquake (TM Dig works at Lv 38+), Dragon Claw
Mega Lucario	Fighting/Steel — Bullet Punch priority kills Emolga; Power-Up Punch ramps for Heliolisk. Bone Rush 4× kills Magneton.	Bone Rush, Power-Up Punch, Bullet Punch
Diggersby (Bunnelby evo with Huge Power)	Earthquake at high Attack one-shots Magneton, 2HKOs Heliolisk. Doesn't help vs Emolga (immune to Ground).	Earthquake, Mud Shot
Nidoking (if you used Moon Stone in Phase 3)	Earth Power destroys Magneton. Bench against Emolga.	Earth Power, Poison Jab
Mega Charizard X	Tough Claws + Fire/Dragon STAB. Don't pick Mega Charizard Y — Drought activates Dry Skin healing on Heliolisk!	Flare Blitz, Dragon Claw
Hawlucha / Tyrantrum	Rock/Flying picks counter Emolga specifically. Tyrantrum's Stone Edge OHKOs Emolga.	Stone Edge, Rock Slide

Avoid leading with

Greninja / Frogadier / Lapras / any Water — Electric 2× weak. Heliolisk's Thunderbolt OHKOs them.
Mega Charizard Y — its Drought triggers Heliolisk's Dry Skin heal. Use Mega Charizard X if you have it, not Y.
Talonflame / Fletchinder — Fire/Flying weak to Electric and Rock. Brave Bird recoil + Thunderbolt = dead.
Mareep / Flaaffy / Ampharos (yours) — Electric mirror, slow chip.
Vivillon / Volcarona — Bug/Flying 4× Rock if you brought one — bad here.

Reward

Voltage Badge — traded Pokémon up to Lv 80 obey. ★ Big upgrade.
TM24 Thunderbolt — ★ ★ ★ One of the best moves in the game. 90 power Electric with 10% paralysis chance. Slap on Heliolisk, Magneton, Mega Ampharos, Raichu, Pikachu, Mareep/Flaaffy/Ampharos, Galvantula. Universal answer to bulky Water Pokémon for the rest of the run.
Prize money — ~4,440 P.
