Written for Black & White
These are the Gym Leaders of Pokémon Black & White (2010). Black 2 & White 2 have several different Leaders and teams.
Striaton City Gym
Gym Leader: Cilan, Cress and Chili
Type: Multi
Prize: Trio Badge, TM83 Work Up
| Lillipup @ Level 12 – Bite – Work Up – Odor Sleuth – Helping Hand |
   Pansear/Pansage/Panpour @ Level 14 – Incinerate / Vine Whip / Water Gum – Fury Swipes – Work Up – Lick |
These guys lead a weird gym. Depending on your starter, they change. If you pick Snivy, you’ll face Chili, who has Pansear. If you picked Tepig, you’ll have to battle Cress, who has Panpour. Finally, if you picked Oshawott, you’ll face Cilan and his Pansage. Each trainer also has a Lillipup.
The best strategy to defeat Cilan, Cress and Chili is utilizing the gift Pokémon given to you in the Dreamyard. There’s a young woman there willing to give you a Pokémon, depending on your starter. But instead of giving you the type-advantageous Pokémon, she’ll give you the type-disadvantageous one. So if you picked Tepig, she’ll give you a Pansage, which you can use against Cress’s Panpour.
Basically, use that Pokémon to take them out.
Nacrene City Gym
Leader: Lenora
Type: Normal
Prize: Basic Badge, TM67 Retaliate
 Herdier @ Level 18 – Bite – Take Down – Retaliate – Leer |
 Watchog @ Level 20 – Hypnosis – Leer – Retaliate – Crunch |
A good Fighting-type Pokémon will come in handy here. I’d stay away from using Munna because of Watchog’s Crunch. Due to poor type coverage, you can probably take them out with your starter. If that’s not what you’re looking for, try training a Timburr. They can be found near Pinwheel Forest.
Castelia City Gym
Leader: Burgh
Type: Bug
Prizes: Beetle Badge, TM76 Struggle Bug
 Whirlipede @ Level 21 – Struggle Bug – Poison Tail – Screech – Pursuit |
 Dwebble @ Level 21 – Struggle Bug – Smack Down – Faint Attack – Sand-attack |
 Leavanny @ Level 23 – Razor Leaf – Struggle Bug – String Shot – Protect |
All you need here is a really good Flying-type Pokémon. Tranquill and Swoobat will do the trick well, but watch out for Dwebble’s Smack Down (or Faint Attack for Swoobat users.) Fire-types work well too, especially Special Fire. Pansage users will have fun in this gym.
Nimbasa City Gym
Leader: Elesa
Type: Electric
Prizes: Bolt Badge, TM72 Volt Switch
 x2Emolga @ Level 25 – Pursuit – Volt Switch – Aerial Ace – Quick Attack |
 Zebstrika @ Level 27 – Flame Charge – Volt Switch – Quick Attack – Spark |
A Ground-type is really useful in this gym, especially with a Rock-type move for her Emolgas. Excadrill is a perfect candidate and can Slash Emolga away and focus on Zebstrika. Watch out for his Flame Charge!
Driftveil City Gym
Leader: Clay
Type: Ground
Prizes: Quake Badge, TM78 Bulldoze
 Krokorok @ Level 29 – Crunch – Bulldoze – Swagger – Torment |
 Palpitoad @ Level 29 – Bulldoze – Muddy Water – Aqua Ring – Bubblebeam |
 Excadrill @ 31 – Slash – Rock Slide – Bulldoze – Hone Claws |
A Grass-type Pokémon is preferable and a Water-type will help you take out Clay’s team. The Grass-type is primarily for Palpitoad, but will suffice for Krokorok and dent Excadrill. Water will be more effective on Excadrill but won’t hurt Palpitoad much.
Mistralton City Gym
Leader: Skyla
Type: Flying
Prizes: Jet Badge, TM62 Acrobatics
 Swoobat @ Level 33 – Heart Stamp – Amnesia – Acrobatics – Assurance |
 Unfezant @ Level 33 – Quick Attack – Air Slash – Leer – Razor Wind |
 Swanna @ Level 35 – Bubblebeam – Aerial Ace – Air Slash – Aqua Ring |
The best choice for Skyla is an Electric-type. With Chargestone Cave nearby, the game begs for you to use a strong Electric-type like Galvantula or Eelektrik. Rock also works, but Swanna may prove difficult.
Icirrus City Gym
Leader: Brycen
Type: Ice
Prizes: Icicle Badge, TM79 Frost Breath
 Vanillish @ Level 37 – Mirror Shot – Frost Breath – Acid Armor – Astonish |
 Cryogonal @ Level 37 – Rapid Spin – Reflect – Frost Breath – Aurora Beam |
 Beartic @ Level 39 – Slash – Brine – Swagger – Icicle Crash |
A Fighting-type is your best bet for Brycen. With Beartic’s Brine, a slower Fire-type would have some trouble, as well as Rock-types. Rock-types may not even get pass Vanillish’s Mirror Shot. Fighting-types have free roam over Brycen’s team.
Opelucid City Gym
Leaders: Drayden (Black) / Iris (White)
Type: Dragon
Prizes: Legend Badge, TM82 Dragon Tail
Both teams are similar. However, Iris’s Pokémon are all Females and Drayden’s are all males. Iris’s Druddigon also has Sheer Force instead of Rough Skin.
 Fraxure @ Level 41 – Dragon Dance – Dragon Rage – Dragon Tail – Assurance |
 Druddigon @ Level 41 – Chip Away – Revenge – Dragon Tail – Night Slash |
 Haxorus @ Level 43 – Dragon Dance – Slash – Dragon Tail – Assurance |
Ice-types are key! Beartic’s Icicle Crash should suffice, but Vanilluxe’s great defence will also help too. It’s all up to you…. Or you could use your own Haxorus or Druddigon on them.
