Man, looking back at 1998, we really didn't know what we were doing. We were just kids with brick-sized Game Boys and a dream, probably picking Charmander because he looked the coolest on the box art and then immediately getting our teeth kicked in by a guy with some rocks. That's the thing about the Pokemon Blue gym leaders. They weren't just bosses. They were these massive skill checks that forced you to actually learn how the game worked, even if "how the game worked" back then was a buggy, unbalanced mess where Psychic types were basically gods and Focus Energy actually made your critical hit rate worse.
If you're jumping back into Kanto on a Virtual Console or a dusty cartridge, you've gotta realize that the game isn't just about levels. It’s about the weird quirks of Generation I.
Brock and the Boulder Badge Struggle
Honestly, Brock is the ultimate "Welcome to Pokemon" slap in the face if you chose Charmander. He's sitting there in Pewter City with a Geodude and an Onix. In Pokemon Blue, Onix only knows Tackle and Bide, but when you're level 10 and doing 2 damage with Scratch, Bide feels like a death sentence. Most players think they just need to grind. You don't. You catch a Mankey on Route 22 (if you're playing Yellow) or you just Nidoran-kick your way to victory. In Blue, you're basically stuck using Butterfree's Confusion or just over-leveling until Ember finally chips away at those rocks.
It’s a brutal start. But it teaches you the most important lesson of the game: type matchups are everything. If you don't respect the types, Brock will end your journey before you even see a Zubat.
Misty: The Starmie Menace
Misty is where the difficulty curve spikes like a heart rate monitor. Cerulean City is beautiful, the music is iconic, and then you meet that Starmie. It’s fast. It’s strong. And in the original Pokemon Blue, it knows Bubblebeam. Because of the way "Special" worked as a single stat back then, Starmie was both a tank and a glass cannon that wasn't actually made of glass.
If you didn't grab a Pikachu in Viridian Forest or a Bellsprout/Oddish north of the city, you are going to have a bad time. Starmie’s AI isn't even that smart, but it doesn't need to be when it outspeeds your entire team. I’ve seen entire playthroughs die right here because someone tried to "brute force" it with a Pidgeotto. Don't do that. Go get a Grass type.
Lt. Surge and the Trash Can Puzzle
Everyone remembers the trash cans. It’s easily the most annoying "puzzle" in the history of the franchise. You’re in Vermilion City, you’ve got your Cut HM, and you just want to fight the guy with the Raichu. Instead, you’re clicking on garbage bins like a frantic janitor.
Surge himself? He’s a bit of a glass cannon. His Raichu has Thunderbolt, which hits like a truck, but if you went to Diglett’s Cave—which is literally right next door—you basically win. A single Diglett with Dig makes Lt. Surge look like a total amateur. It’s funny how the game provides the exact solution to the problem just a few steps away, yet so many people struggle here because they want to use their favorites instead of the "right" tool for the job.
The Mid-Game Slump: Erika, Koga, and Sabrina
By the time you hit the middle of the Pokemon Blue gym leaders circuit, the game opens up. You can kind of do these in different orders depending on how you travel.
Erika is the "breather" boss. If you have a Fire type or a Pidgeot, Celadon Gym is a cakewalk. The only real danger is getting paralyzed or put to sleep, which is more of an annoyance than a threat. Her Victreebel and Vileplume are iconic, sure, but they’re slow.
Koga, on the other hand, is a jerk. He’s the master of "I'm going to make this take forever." He loves Minimize and Toxic. In Pokemon Blue, Toxic had a weird interaction where if you also used Leech Seed, the damage would scale together and delete the opponent’s HP bar in seconds. Koga doesn't do that to you, but he definitely tries to stall you out.
Then there’s Sabrina.
We need to talk about Sabrina. In Generation I, Psychic types had no real weaknesses. Bug moves were weak (basically just Twinneedle or Leech Life), and Ghost moves were actually glitched to have no effect on Psychic Pokemon, despite what the anime told us. Sabrina’s Alakazam is a nightmare. It has high Special and incredible Speed. Honestly, the best way to beat her isn't even a strategic type matchup; it's just hitting her with the strongest physical moves you have. Snorlax using Body Slam is a much better counter to Sabrina than any "intended" strategy.
Blaine and the Cinnabar Quiz
Cinnabar Island feels like the end of the world. It’s remote, it’s volcanic, and the gym is hidden inside a burnt-out mansion... wait, no, it's behind a locked door that requires a key from the mansion. The gym itself is a trivia show. If you know your Pokemon facts, you don't even have to fight the trainers.
Blaine's Arcanine is cool, but at this point in the game, you’ve likely crossed the ocean on the back of a Lapras or a Blastoise. Surf is one of the best moves in the game, and Blaine is weak to it. It’s a bit of a letdown after the terror of Sabrina, but it’s a fun victory lap before the final challenge.
The Final Reveal: Giovanni
The twist that the Viridian City Gym leader is actually the leader of Team Rocket was mind-blowing for an eight-year-old in the 90s. Giovanni is the Ground-type master, but by the time you reach him, your team should be level 45-50.
His Rhyhorn, Dugtrio, Nidoqueen, Nidoking, and Rhydon are formidable, but they all share a massive weakness to Water and Ice. If you kept that Lapras from Silph Co., you can basically solo this entire gym. Giovanni isn't actually the hardest fight in the game—that honor goes to your Rival at the end of the Elite Four—but he’s the most thematic. It’s the final showdown against the mob boss who has been bothering you since Mt. Moon.

Why the Blue Gyms Hit Different
There's a specific kind of jank in Pokemon Blue that modern games lack. The AI is programmed to use "super effective" moves, but it doesn't always check if those moves do damage. This is why Lance’s Dragonite will spam Agility against a Poison-type Pokemon—because Agility is a Psychic-type move, and Psychic is "good" against Poison, even though Agility doesn't deal damage.
The gym leaders in this era weren't just characters; they were puzzles defined by the limitations of the Game Boy. They were the gatekeepers of the "color" badges that let you control higher-level Pokemon. Without them, you were just a kid with a lizard. With them, you were a Champion.
Quick Strategy Refresher for Your Next Run:
- Don't ignore X-Items. X-Attack and X-Speed are actually broken in Gen I because they boost stats by huge margins.
- The "Special" Stat is King. Since Special Attack and Special Defense are one number, Pokemon like Amnesia Snorlax or Slowbro become unkillable gods.
- Speed determines Crit Rate. In Blue, the faster the Pokemon, the more likely it is to land a critical hit. This is why Persian and Jolteon are terrifying.
- Sleep is a death sentence. In this version of the game, a Pokemon does not move the same turn it wakes up. If you're slower than the opponent, they can just put you back to sleep forever.
The journey through the Kanto gyms is less about the "story" and more about the friction. It’s the struggle against Brock’s defense, the frustration of Misty’s Starmie, and the sheer awe of standing in front of Giovanni. Even with all the bugs and the weird balance issues, those eight leaders remain the blueprint for what a boss rush should feel like in an RPG.
If you're looking to optimize your team, prioritize getting a strong Water type early and don't sleep on the "boring" Normal types like Raticate or Fearow for the early game. They fall off later, but they'll get you through the first three badges while your starter is still struggling to find its footing. Diglett’s Cave is your best friend for Surge, and the Celadon Department Store is your best friend for literally everything else, thanks to the TMs and stones they sell there.
Go get those badges. Just watch out for the trash cans in Vermilion. They're still as annoying as you remember.
Actionable Next Steps for Trainers
To successfully clear all eight gyms in a single run without unnecessary grinding, you should prioritize catching a Nidoran (Male or Female) on Route 22 early on. Its access to Double Kick at level 12 (in most versions) or early evolution via Moon Stone provides the physical coverage needed to bypass Brock and Lt. Surge. Additionally, save your TM11 (Bubblebeam) from Misty for a high-special Pokemon like Starmie or even a Nidoking to handle the mid-game Fire and Ground types. Finally, ensure you pick up the Silph Co. Lapras in Saffron City; its Water/Ice typing is the single most effective counter for both the eighth gym and the eventual Elite Four.
