Let's Go Pikachu Eevee Gym Leaders

Gym #1 Pewter City Gym - Leader Brock

Leader: Brock

Rewards: Boulder Badge | TM01 - Headbutt

#1 Geodude

Geodude

Type: Rock
Lv: 11
Moves:
Tackle Normal

#2 Onix

Onix

Type: Rock Ground
Lv: 12
Moves:
Headbutt Normal
Bind Normal
Rock Throw Rock

Strategy

The battle with Brock should be pretty straightforward. He might outlevel you if you haven't done any grinding at this point, although he will likely be the last gym leader to do so. You can easily overcome this with a Water or Grass type Pokemon that knows a STAB move. Both of Brock's pokemon are Rock and Ground type, meaning both Water and Grass type moves are 4x as effective.

Gym #2 Cerulean City Gym - Leader Misty

Let's Go Pikachu Eevee Misty Let's Go Pikachu Eevee Misty

Leader: Misty
Type
Rewards: Cascade Badge | TM29 - Scald

#1 Psyduck

Psyduck

Type: Water
Lv: 18
Moves:
Water Gun Water
Confusion Psychic

#2 Starmie

Starmie

Type: Water Psychic
Lv: 19
Moves:
Scald Water
Psywave Psychic
Swift Normal

Strategy

By the time you get to Misty, your Pokemon should be around her level if you have been fighting trainers and catching some Pokemon. Electric and Grass type moves will deal double damage to both of her Pokemon and she won't have any moves strong against them. Watch out for Confusion from Psyduck and being burned by Scald. If your partner is Pikachu, this battle is guranteed to be a piece of cake.

Gym #3 Vermillion City Gym - Leader Lt. Surge

Let's Go Pikachu Eevee Lt. Surge Let's Go Pikachu Eevee Lt. Surge

Leader: Lt. Surge
Type Electric
Rewards: Thunder Badge | TM36 - Thunderbolt

#1 Voltorb

Voltorb

Type: Electric
Lv: 25
Moves:
Thunderbolt Electric
Swift Normal
Light Screen Psychic

#2 Magnemite

Magnemite

Type: Electric Steel
Lv: 25
Moves:
Thunderbolt Electric
Sonic Boom Normal

#3 Raichu

Raichu

Type: Electric
Lv: 26
Moves:
Thunderbolt Electric
Quick Attack Normal
Double Kick Fighting

Strategy

Lt. Surge is the first Gym Leader to use three pokemon. They are all Electric, but Magnemite is also Steel type. If you have a Ground type Pokemon, this just means that you are now dealing 4x the damage. However, most types in the game do half damage against Steel, so watch out for that. If you're looking for a Ground type, you can always stop by the nearby Diglett's Cave. His signature Raichu is quick and powerful, but will be rendered basically useless against a Ground type.

Gym #4 Celadon City Gym - Leader Erika

Let's Go Pikachu Eevee Erika Let's Go Pikachu Eevee Erika

Leader: Erika
Type Grass
Rewards: Rainbow Badge | TM53 - Mega Drain

#1 Tangela

Tangela

Type: Grass
Lv: 33
Moves:
Mega Drain Grass
Sleep Powder Grass
Bind Normal

#2 Weepinbell

Weepinbell

Type: Grass Poison
Lv: 33
Moves:
Mega Drain Grass
Poison Jab Poison

#3 Vileplume

Vileplume

Type: Grass Poison
Lv: 34
Moves:
Mega Drain Grass
Moonblast Fairy

Strategy

Erika uses Grass type Pokemon. Fire and Ice types are both super effective, but aren't very common at this point in the game. Poison and Bug do a lot of damage against Grass and are readily available, but Weepinbell and Vileplume are part Poison, so they won't work well either. This leaves Flying as the go-to type for an advantage against Erika. All of her Pokemon know Mega Drain, so be prepared for them to be constantly healing themselves. You'll also have to watch out for the rather annoying Sleep Powder and Poison Jab, so it's a good idea to carry a couple Awakenings and Antidotes going into this battle.

Gym #5 Fuchsia City Gym - Leader Koga

Let's Go Pikachu Eevee Koga Let's Go Pikachu Eevee Koga

Leader: Koga
Type Poison
Rewards: Soul Badge | TM27 - Toxic

#1 Weezing

#2 Muk

#3 Golbat

Golbat

Type: Poison Flying
Lv: 43
Moves:
Toxic Poison
Protect Normal
Fly Flying
Leech Life Bug

#4 Venomoth

Venomoth

Type: Bug Poison
Lv: 44
Moves:
Sludge Bomb Poison
Protect Normal
Psychic Psychic
Bug Buzz Bug

Strategy

Koga might be a little more difficult if you attempt him before Saffron City Gym. Otherwise, you should be overpowered at this point. He uses Poison type Pokemon. Ground types are traditionally good against Poison, but because Golbat is part Flying and Venomoth is part Bug, it's probably not the best option. Psychic moves are super effective against all his Pokemon, just watch out if your Pokemon is actually Psychic, as Leech Life and Bug Buzz will do a lot of damage.

Gym #6 Saffron City Gym - Leader Sabrina

Let's Go Pikachu Eevee Sabrina Let's Go Pikachu Eevee Sabrina

Leader: Sabrina
Type Psychic
Rewards: Marsh Badge | TM33 - Calm Mind

#1 Mr. Mime

#3 Jynx

Lv: 43
Moves:

Lovely Kiss Normal
Ice Punch Ice

#4 Alakazam

Alakazam

Type: Psychic
Lv: 44
Moves:
Psychic Psychic
Night Shade Ghost

Strategy

The difficulty of this battle is partially determined by if you choose to defeat Koga first or not. Either way, Sabrina uses Psychic type Pokemon which are always rather deadly. Dark types can sweep the whole team, but are pretty hard to come by in Kanto. Bug type is the better choice then. Either way, Mr. Mime is part Fairy so that will make things more difficult, although he knows no Fairy type moves. Yawn and Ice Punch are also on the table for putting you to sleep or freezing your Pokemon, so come prepared.

Gym #7 Cinnabar Island Gym - Leader Blaine

Let's Go Pikachu Eevee Blaine Let's Go Pikachu Eevee Blaine

Leader: Blaine
Type Fire
Rewards: Volcano Badge | TM46 - Fire Blast

#1 Magmar

#2 Rapidash

#3 Ninetales

Moves:
Flare Blast Fire
Quick Attack Normal

#4 Arcanine

Arcanine

Type: Fire
Lv: 47
Moves:
Flare Blitz Fire
Outrage Dragon
Crunch Dark

Strategy

Blaine is a true Fire type user, all four of his Pokemon are pure Fire type. This means Water is the clear choice, he won't have anything he can do about it. Just watch out to avoid being burned. His Pokemon aren't leveled much higher than the preivous gym either, so if you went out of your way to explore some other areas and leveld up a few times, this battle should be quite easy.

Gym #8 Viridian City Gym - Leader Giovanni

Let's Go Pikachu Eevee Giovanni Let's Go Pikachu Eevee Giovanni

Leader: Giovanni
Type Ground

#1 Dugtrio

#4 Rhydon

Rhydon

Type: Ground Rock
Lv: 50
Moves:
Earthquake Ground
Rock Slide Rock
Megahorn Bug

Strategy

The final Gym Leader is Giovanni, who uses Ground type Pokemon. This means he won't be battling with his signature Persian. If you used a Water type to sweep Blaine's team, use the same one for Giovanni. He too can't contest it. Ice type also works well, so why not the Lapras you got from Silph Co? Only thing to look out for here is Nidoking, as he has the ability to poison.
