The gym leaders of Pokémon are designed to be roadblocks to the trainer, challenging them to prove their worth and show what they have learned in their adventure so far. For the most part, these masters of their respective Pokémon types aren’t too difficult to take down, but some stand out among their peers as true challenges.
These gym leaders can take the mastery of their elemental type to new heights, oftentimes in stark contrast to those who came before them, and can make the player realize they aren’t as good at the game as they once thought.
10 Lt. Surge
In Pokémon Red and Blue, Lt. Surge isn’t too much of a challenge. With his team being around level 24, there’s not much of a level jump between him and Misty, with many teams being more than capable of defeating him without needing to grind. Pokémon Yellow, on the other hand, jacks his already scary Raichu up to level 28, much higher than any other Pokémon seen up until then. Although he can be easily defeated if players choose to catch a Dugtrio in Diglett Cave, they tend to be around level 30 and can easily sweep unsuspecting teams during the effort to catch one.
9 Lenora
The second gym leader in Pokémon Black and White is notorious for how irritating her Watchog is. Aside from being a fully evolved Pokémon at a point in the game where players will only be on their second form starter, as well as many Pokémon caught around this time not having evolved at all, it can make this battle challenging to say the least. To make matters even worse, her Watchog likes to use Hypnosis a whole lot before OHKOing a player’s entire team with Retaliate. Even Ghost-types aren’t safe, as it also knows Crunch to cover this particular weakness.
8 Morty
The fourth gym leader in Pokémon Gold and Silver might not have the notoriety of Whitney, the preceding gym leader, but that doesn’t mean he isn’t a tough challenge. Although a few of his Ghost-types are real push-overs, his Gengar is what proves to be the undoing of many players.
Gengar’s ridiculous speed, particularly when compared to other available Pokémon around this point in the game, makes it almost certain that it will attack first in battle, an annoyance when it has the likes of Hypnosis and Dream Eater at its disposal. It also has Shadow Ball, a very powerful Ghost-type move that hits much harder than any other attack the player’s Pokémon are likely to have at the time.
7 Elesa
Electric-type gym leaders seem to always cause players trouble, and Elesa from generation five is no exception. What makes her battle so infuriating are her Emolga which, aside from being part Flying-type (making them immune to Ground-type moves), also like to switch out of the battle with Volt Switch when faced with a real threat. Her signature Pokémon, Zebstrika, is no weakling either, with Flame Charge to not only cover its Grass-type weakness but also boost its speed even higher than it already is.
6 Norman
For many players in Pokémon Ruby and Sapphire, facing down the main character’s father is the ultimate challenge in the game. Although he specializes in Normal-type Pokémon, who have no inherent strength against any other type, he manages to be able to hold his own against any threat. The main problem on his team is his Slaking, a Pokémon with base stats higher than most Legendary Pokémon that is only slightly held back by its ability, Truant, which only lets it attack every other turn. For most players, they will need to grind hard before even attempting this battle for the first time.
5 Winona
Yet another generation three gym leader that tends to grief players is Winona, the Flying-type specialist. Unlike Falkner from Pokémon Gold and Silver, who was only mildly annoying, Winona is a much more serious threat, particularly when it comes to her signature Pokémon. Altaria isn’t the best Flying-type around, but it makes up for its middling stats with its moveset: Dragon Dance, Earthquake, Aerial Ace, and Dragon Breath. Stat boosting moves and good coverage make it nearly impossible to avoid losing at least one team member when facing this fluffy bird down. Altaria did get weakened in Pokémon Omega Ruby and Alpha Sapphire, losing Dragon Dance and Aerial Ace, but also gained Cotton Spore and Roost, which just makes it a different kind of annoying.
4 Koga
Poison-type Pokémon are always a pain for players to deal with, as they tend to inflict the Poisoned status with every other move they use, which can make any battle with them a race against the clock. Koga liked to take it one step further than this, with many of his Pokémon’s supporting moves doing equally annoying things.
Minimize on his Muk made it nearly impossible to hit, as well as Double Team on his Crobat in later games for the same effect, and his Koffing and Weezing liked to Self Destruct at the worst possible times.
3 Sabrina
One of the other gym-leader choices that opens up to the player around the midway point of generation one is Sabrina, the Psychic-type leader. While these days her team is strong, but not impossible to take down, in the original titles she was a major challenge. With the only Ghost-type moves being Lick, a terrible move, and Night Shade, which didn’t do super effective damage, the only way to take down her mighty Alakazam was with neutral attacks, which wasn’t always guaranteed since it’s so fast. It also has Recover, meaning if players don’t take it out quickly, it’s going to stick around far longer than it should.
2 Whitney
Whitney is infamous among the Pokémon fanbase for being one of the hardest challenges in the entire series. To make her even more of a challenge, her Miltank actually got stronger in remakes, rather than weaker as was the case with other hard gym leaders. Rollout can snowball out of control very fast, and Milk Drink can undo all of a player’s hard work in a second. In HeartGold and SoulSilver, it also has the ability Scrappy, which lets Normal-type moves hit Ghost-types when they normally wouldn’t, and it holds a Lum Berry to undo any status players try to inflict on it.
1 Fantina
In Pokémon Platinum, the order that players challenge gym leaders is altered slightly, with Fantina appearing much earlier in the game than she did in Pokémon Diamond and Pearl. As her team’s level is reduced, this shouldn’t have been a problem, except for the fact that her Mismagius is far stronger than anything players can feasibly obtain by that point in the game. It also has a decent coverage moves, like Magical Leaf and Psybeam, meaning it’s going to hit hard no matter what its type match up is.
