The Best Water-Type Pokémon to Use in Pokémon FireRed and LeafGreen
Water-type Pokémon are a valuable addition to any team and perform exceptionally well in the Kanto region of FireRed and LeafGreen. They are especially effective against key Gym Leaders like Brock, Blaine, and Giovanni, who are all highly vulnerable to strong Water-type attacks.
Offensively, water attacks are super effective against Fire, Ground, and Rock-type Pokémon, while also hitting 11 other types for neutral damage. Defensively, they have only two weaknesses: Grass and Electric.
Their utility goes beyond the battlefield as well. Many Water-types can learn Surf and Waterfall, making them essential for navigating the waterways throughout the Kanto region.
Below are my picks for the top Water-type Pokémon in Pokémon FireRed and LeafGreen.
Starmie
Exclusive to LeafGreen, 
Starmie stands out as arguably the best Water-type in the game. Its Water/Psychic typing is excellent for both offense and defense. With a base Speed of 115, it’s the fastest Water Pokémon available, allowing it to out speed most opponents.
Its move pool is highly versatile, allowing it to hit hard with 
Surf and 
Psychic, which benefit from STAB (Same Type Attack Bonus), while also offering excellent coverage with 
Thunderbolt and 
Ice Beam, all backed by its strong base 100 Special Attack. With the right setup, Starmie can hit most Pokémon for super effective damage and is fully capable of sweeping the Elite Four on its own.
The main downside is its heavy reliance on TMs. To reach its full potential, you’ll need to invest time at the Game Corner to obtain 
Ice Beam and Thunderbolt, while the Psychic TM is easily obtained from Mr. Psychic’s house in Saffron City.
You can obtain Starmie by first fishing for a 
Staryu in the following locations: Pallet Town, Vermilion City, Cinnabar Island, One Island, Icefall Cave, and Five Island. Staryu can evolve into Starmie immediately by using a 
Water Stone purchased at the Celadon City Department Store.
Lapras
Lapras is another standout choice thanks to its excellent stats, typing, and move pool. With a massive base 130 HP and solid 80/95 defenses, it’s bulky enough to comfortably take multiple hits. However, it’s far from passive. Its Water/Ice typing gives it a strong offensive presence, allowing it to deal heavy damage with STAB Surf and Ice Beam. Like Starmie, Lapras makes excellent use of Electric-type coverage to deal with opposing Water types. With its ability Water Absorb, it becomes an especially effective counter, taking no damage from their Water attacks. While Thunderbolt is a reliable option, choosing Water Absorb over Shell Armor also opens up a powerful Rain Dance + Surf + Thunder combination. In rain, Lapras can unleash boosted Surfs and perfectly accurate Thunders, all while remaining immune to incoming Water-type moves.
Lapras also shines with its level-up move pool, offering valuable utility through moves like 
Body Slam, Sing, Perish Song, and 
Confuse Ray. And to put the icing on the cake, Ice Beam is learned naturally, saving you the time and resources needed to buy the TM from the Game Corner.
After defeating your rival in the Silph Co. building in Saffron City, speak to the employee on the third floor to receive Lapras.
Gyarados
If you’re willing to put in the effort to raise a 
Magikarp to level 20, you’ll be rewarded with one of the most monstrous Pokémon in the game. The Water/Flying-type 
Gyarados boasts a massive base 125 Attack along with solid 95/79/100 bulk, further enhanced by its Intimidate ability, allowing it to pulverize your opponents and shrug off most attacks that aren’t Electric-type.
Unlike the other Water-types on this list, Gyarados relies primarily on its powerful physical Attack rather than special-based STAB and coverage moves. While Water Pulse and Surf are still useful for handling Rock and Ground-types, it dishes out the most damage with moves like Thrash, Strength, Return, Double-Edge, 
Earthquake, and Hyper Beam. Once it reaches level 50, it learns 
Dragon Dance, an attack that boosts both Attack and Speed, turning Gyarados into a devastating sweeper after just one turn of setup.
While its Gen 3 version isn’t quite as dominant as it becomes in later generations, Gyarados is still an incredibly strong and reliable choice in FireRed and LeafGreen.
You can obtain Gyarados the earliest by purchasing a Magikarp for 500 Poké Dollars from the man in the Pokémon Center outside Mt. Moon. Otherwise, you can wait until you get the 
Old Rod in Vermilion City and catch a Magikarp in almost any body of water. You can also fish up a wild Gyarados later in the game using the 
Super Rod in select locations.
Vaporeon
Vaporeon is one of the most consistent mono-Water types available, offering an excellent balance of durability and firepower. Its standout base 130 HP, paired with a strong 110 Special Attack, lets it comfortably tank hits while dealing solid damage in return.
If you save the Water Pulse TM you can immediately teach it to Vaporeon, giving it a decent STAB option until you acquire the HM for Surf. Vaporeon also benefits from useful level-up coverage like 
Bite and Aurora Beam. That being said, you’ll eventually want to upgrade Aurora Beam to Ice Beam via the Celadon Game Corner TM.
What sets Vaporeon apart is its ability to play a more defensive role. With its natural bulk, it can stall effectively using 
Toxic, boost its survivability with Acid Armor, and recover health with Rest, making it surprisingly hard to take down.
To obtain Vaporeon, evolve the 
Eevee you receive in Celadon City using a Water Stone purchased from the Celadon Department Store.
Blastoise
Blastoise is the definition of a classic, well-rounded Water-type. While none of its stats particularly stand out, its balanced spread makes it a consistently reliable choice throughout the game. One of its biggest advantages is availability. Choose 
Squirtle as your starter, and you’ll have access to Blastoise and its full evolution line from start to finish.
It performs especially well early on, easily handling Brock’s Rock-types and holding its own against Misty by tanking hits from Staryu and Starmie while dealing super effective damage on the latter with Bite. It can also make immediate use of the Water Pulse TM after earning it from the Cerulean City Gym.
Beyond the standard Surf and Ice Beam combo, Blastoise has access to useful coverage options like Dig and Earthquake, allowing it to better deal with Electric and Poison-types and round out its move set.
Verdict
Not only is Water one of the best types in FireRed and LeafGreen, it’s also the most represented for fully evolved Pokémon, giving you more viable team options than any other type in the game.
Honorable mention to 
Slowbro (LeafGreen exclusive) who plays as a slower, bulkier Starmie, but can set up Calm Mind for powerful sweeps.
Ultimately, the best Water-type Pokémon for your team will depend on your playstyle and what roles you need to fill, but you really can’t go wrong with any of these top picks.
