Let's Go Pikachu Eevee Gym Leaders
Gym #1 Pewter City Gym - Leader Brock
Leader: Brock
Type
Recommended
Rewards: Boulder Badge | TM01 - Headbutt
#1 Geodude
Type:
Lv: 11
Moves:
Tackle
#2 Onix
Type:
Lv: 12
Moves:
Headbutt
Bind
Rock Throw
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
Leader: Misty
Type
Recommended
Rewards: Cascade Badge | TM29 - Scald
#1 Psyduck
Type:
Lv: 18
Moves:
Water Gun
Confusion
#2 Starmie
Type:
Lv: 19
Moves:
Scald
Psywave
Swift
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
Leader: Lt. Surge
Type
Recommended
Rewards: Thunder Badge | TM36 - Thunderbolt
#1 Voltorb
Type:
Lv: 25
Moves:
Thunderbolt
Swift
Light Screen
#2 Magnemite
Type:
Lv: 25
Moves:
Thunderbolt
Sonic Boom
#3 Raichu
Type:
Lv: 26
Moves:
Thunderbolt
Quick Attack
Double Kick
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
Leader: Erika
Type
Recommended
Rewards: Rainbow Badge | TM53 - Mega Drain
#1 Tangela
Type:
Lv: 33
Moves:
Mega Drain
Sleep Powder
Bind
#2 Weepinbell
Type:
Lv: 33
Moves:
Mega Drain
Poison Jab
#3 Vileplume
Type:
Lv: 34
Moves:
Mega Drain
Moonblast
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
Leader: Koga
Type
Recommended
Rewards: Soul Badge | TM27 - Toxic
#1 Weezing
Type:
Lv: 43
Moves:
Toxic
Protect
Sludge Bomb
Explosion
#2 Muk
Type:
Lv: 43
Moves:
Toxic
Protect
Sludge Bomb
Moonblast
#3 Golbat
Type:
Lv: 43
Moves:
Toxic
Protect
Fly
Leech Life
#4 Venomoth
Type:
Lv: 44
Moves:
Sludge Bomb
Protect
Psychic
Bug Buzz
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
Leader: Sabrina
Type
Recommended
Rewards: Marsh Badge | TM33 - Calm Mind
#1 Mr. Mime
Type:
Lv: 43
Moves:
Psychic
Reflect
Light Screen
Double Slap
#2 Slowbro
Type:
Lv: 43
Moves:
Psychic
Yawn
Surf
Calm Mind
#3 Jynx
Type:
Lv: 43
Moves:
Psychic
Lovely Kiss
Ice Punch
#4 Alakazam
Type:
Lv: 44
Moves:
Psychic
Night Shade
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
Leader: Blaine
Type
Recommended
Rewards: Volcano Badge | TM46 - Fire Blast
#1 Magmar
Type:
Lv: 47
Moves:
Flamethrower
Low Kick
Confuse Ray
#2 Rapidash
Type:
Lv: 47
Moves:
Flare Blitz
Quick Attack
Fury Attack
#3 Ninetales
Type:
Lv: 47
Moves:
Flare Blast
Quick Attack
#4 Arcanine
Type:
Lv: 47
Moves:
Flare Blitz
Outrage
Crunch
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 leveled up a few times, this battle should be quite easy.
Gym #8 Viridian City Gym - Leader Giovanni
Leader: Giovanni
Type

Rewards: Earth Badge | TM41 - Earthquake
#1 Dugtrio

Moves:
Earthquake
Sucker Punch

#2 Nidoqueen

#3 Nidoking

Moves:

Horn Drill
Megahorn
Poison Jab
#4 Rhydon
Type:
Lv: 50
Moves:
Earthquake
Rock Slide
Megahorn
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.
