10 Best Water-Type Fusions in Pokémon Infinite Fusion for Your Team

Water is one of the best types in Pokémon Infinite Fusion, and water-type fusions might be the single strongest thing you can put on your team. Water has only two weaknesses, pairs beautifully with almost every other type, and the game’s Water-type parents — Gyarados, Blastoise, Starmie, Suicune — bring elite stats and movepools to any fusion. This guide ranks the 10 best water-type fusions in Pokémon Infinite Fusion for your team, with the typing, role, and key moves for each pick so you can build around them with confidence.

Why Water-Type Fusions Belong on Your Team

Before the rankings, here is why Water deserves a permanent slot on your team. Offensively, Water hits Fire, Ground, and Rock super effectively — three types you will face constantly in Kanto and Johto. Defensively, Water resists Fire, Water, Ice, and Steel while being weak only to Electric and Grass. That defensive profile means a Water fusion can switch into a huge portion of the game’s threats safely.

Fusion makes Water even better. In Infinite Fusion, a fusion’s first type comes from the head’s primary type and its second type from the body’s secondary type, so you can engineer exactly the Water pairing you want: Water/Flying for a physical sweeper, Water/Poison for a special wall, Water/Fighting for coverage, and so on. Pair that with the stat formula — Attack, Defense, and Speed lean toward the body while HP, Special Attack, and Special Defense lean toward the head — and you can build Water fusions for any role your team needs. If you are new to the mechanics, read our guide to how fusion actually works first, then come back and pick your favorites.

How We Ranked the Best Water Fusions

Every fusion below was judged on four things: battle performance (stats and typing for a real role, not just a cool sprite), movepool (access to strong STAB and coverage moves), availability (can you actually build it in a normal playthrough), and versatility (does it fit on many teams or just one gimmick). All typings follow the game’s documented fusion rules, and every pick is obtainable without cheats. New to the game?

The 10 Best Water-Type Fusions in Pokémon Infinite Fusion

1. Venustoise — Venusaur / Blastoise (Grass/Water)

The classic. Venustoise fuses the two most beloved Kanto starters into a Grass/Water tank with roughly 530 total base stats and barely any weaknesses that matter. Grass/Water is a phenomenal defensive typing: it resists Water, Electric, Grass, Ground, and Steel, and its weaknesses (Flying, Poison, Bug) are all manageable with the right coverage move. This is the fusion you build when you want one Pokémon that simply will not die.

What makes Venustoise special is how the parents complement each other. Venusaur’s head contributes strong special stats, so Giga Drain and Sludge Bomb hit hard while recovering HP, and Blastoise’s body brings the physical bulk to shrug off Earthquakes and Stone Edges. Give it Giga Drain, Hydro Pump, Sludge Bomb, and Leech Seed or Toxic, and you have a wall that also threatens everything it faces. It is equally at home stalling out gym leaders and anchoring your Elite Four team. If you only build one fusion from this list, make it this one.

2. Slowgar — Slowbro / Gengar (Water/Poison)

Slowgar is the fusion community’s favorite special wall, and the typing math is beautiful: Slowbro’s head gives the Water primary type while Gengar’s body contributes Poison as the secondary type, resulting in Water/Poison. That typing resists Fighting, Poison, Bug, Steel, Fire, Water, Ice, and Fairy — eight resistances — while its weaknesses (Electric, Ground, Psychic) are all covered by common teammates.

In battle, Slowgar plays like an upgraded Slowbro: enormous physical bulk from the Slowbro side, a genuinely threatening special movepool from the Gengar side, and access to Shadow Ball, Hydro Pump, Sludge Bomb, and Calm Mind or Trick Room. It walls Fighting types all day, which makes it a nightmare for Bruno’s Elite Four team, and it can set up Calm Mind against anything that cannot threaten it. The only real cost is Speed — Slowgar is slow, so pair it with Trick Room support or accept that it will take hits before it moves.

3. Gyaraizard — Gyarados / Charizard (Water/Flying)

If Venustoise is the wall, Gyaraizard is the wrecking ball. Gyarados as the head gives the Water primary type, Charizard’s body supplies Flying as the secondary type, and the stat formula does the rest: Attack and Speed lean toward the body, and Charizard’s body brings exactly the physical attacking frame this fusion wants. The result is a Water/Flying physical sweeper with Dragon Dance, Waterfall, and Earthquake-level coverage.

The game plan is simple: bring Gyaraizard in on something it threatens, use Dragon Dance once or twice, and sweep. Waterfall and Brave Bird (or Wing Attack early) provide strong STAB, while Earthquake from the Charizard side punishes the Electric types that would otherwise check it. Watch out for Stealth Rock-style chip and fast Electric attackers before you set up — but once a boosted Gyaraizard is rolling, very few teams have an answer. Preview both orders in our Pokémon Fusion Calculator before you commit, because the reversed order plays completely differently.

4. Blastiken — Blastoise / Blaziken (Water/Fighting)

Water/Fighting is one of the best offensive typings in the game — it hits Normal, Rock, Steel, Ice, and Dark super effectively — and Blastiken delivers it with two starter-grade stat pools behind it. Blastoise’s head gives the Water primary type and strong special bulk, while Blaziken’s body contributes Fighting as the secondary type plus the physical Attack and Speed this fusion needs to sweep.

Blastiken is flexible in a way few fusions are: it can run physical with Waterfall, Close Combat, and Brave Bird, or mixed with Hydro Pump and Aura Sphere-style coverage. Either way it breaks through the Normal and Steel walls that stall slower teams. It is also one of the easiest top-tier fusions to build — both parents are starters you can obtain in a single playthrough, and neither requires postgame access.

5. Mewtoise — Mew / Blastoise (Psychic/Water)

Mew is the ultimate fusion donor — perfect 100s across every stat and a movepool containing nearly everything — and fusing it with Blastoise produces one of the bulkiest special walls in the game. Mew’s head gives the Psychic primary type and elite special stats, while Blastoise’s single-typed Water body passes Water as the secondary type, giving Mewtoise the excellent Psychic/Water combination.

What do you do with a wall that has 100+ defenses on both sides and access to Recover-style longevity plus every coverage move in the game? Anything you want. Mewtoise can run Calm Mind sets, status-spread sets with Thunder Wave and Toxic, or pure pivot sets with U-turn-style momentum. The honest caveat is availability: Mew is a postgame or event Pokémon, so this is a fusion you build for rematches, the Battle Tower, and showing off — not for your first Elite Four run.

6. Startwo — Starmie / Mewtwo (Water/Psychic)

If Mewtoise is the wall, Startwo is the nuke. Starmie’s head provides the Water primary type and genuinely elite Speed, while Mewtwo’s body — single-typed Psychic — passes Psychic as the secondary type and contributes the highest Special Attack stat in the game to the fusion’s special-leaning stats. The result is a Water/Psychic special sweeper that outruns almost everything and hits like a truck.

Hydro Pump, Psychic, Ice Beam, and Thunderbolt give Startwo perfect neutral coverage against the entire game, and its Speed means it usually moves first to use it. This is the fusion you build when a boss fight has one specific threat you need deleted immediately. Like Mewtoise, it is gated behind Mewtwo’s availability, so plan it as your postgame superweapon rather than a story-mode staple.

7. Empolix — Empoleon / Steelix (Water/Ground)

Water/Ground is famously one of the best defensive typings ever — a single weakness to Grass and resistances to half the type chart — and Empolix brings it with two of the bulkiest parents available. Empoleon’s head gives the Water primary type and strong special stats, while Steelix’s body contributes Ground as the secondary type plus absolutely massive Defense that the stat formula leans into.

Empolix is your answer to Electric types, Rock types, and physical attackers in general. It switches into Thunderbolts for free, sets up Stealth Rock or spreads Toxic, and hits back with Earthquake, Hydro Pump, and Ice Beam coverage. The Grass weakness is real, so keep a Fire or Flying teammate ready — but as a defensive pivot, few fusions in the game do the job better. Check your team composition in our Team Builder to make sure that Grass weakness is covered.

8. Vapoleon — Vaporeon / Jolteon (Water/Electric)

Sometimes the best fusion is the simplest: two Eeveelutions, one brilliant typing. Vaporeon’s head gives the Water primary type and the enormous HP that makes Vaporeon famous, while Jolteon’s single-typed Electric body passes Electric as the secondary type and donates its blistering Speed to the fusion’s physical-leaning stats. Water/Electric has only two weaknesses (Grass and Ground) and fantastic offensive coverage.

Vapoleon plays as a fast pivot: come in on a Water or Flying attack, threaten with Hydro Pump and Thunderbolt, and get out. It is also one of the most accessible strong fusions on this list — Eevee is easy to obtain and both evolution stones are buyable, so you can build Vapoleon long before the Elite Four. If you want the Eeveelution deep-dive first, read our Eevee guide for the best Eeveelution fusions ranked.

9. Articune — Articuno / Suicune (Ice/Water)

The legendary option. Articuno’s head gives the Ice primary type while Suicune’s single-typed Water body passes Water, producing an Ice/Water legendary with two of the best defensive stat pools in the game behind it. Articune is slow, but it does not need Speed — with Pressure stalling, Recover-style longevity from the Suicune side, and Ice Beam + Hydro Pump + Calm Mind, it wins wars of attrition against nearly anything.

This is a fusion for patient players. Set up Calm Mind against a passive opponent, Roost off damage, and sweep with perfectly accurate Blizzard in hail or Ice Beam otherwise. Both parents are roamers or static legendaries, so Articune is strictly a postgame project — but for Elite Four rematches at higher tiers, it is one of the most reliable win conditions you can build.

10. Gyaralax — Gyarados / Snorlax (Water/Normal)

Our final pick is gloriously stupid and extremely effective. Gyarados’s head gives the Water primary type and strong Attack, while Snorlax’s single-typed Normal body passes Normal and donates the biggest HP stat in the game to the fusion. Water/Normal is not a glamorous typing, but Gyaralax does not need glamour — it needs to survive everything and hit back with Waterfall, Body Slam, Earthquake, and Curse-boosted returns.

Gyaralax is the team’s sponge: it switches into special attackers, Curses up while they fail to break it, and sweeps with boosted STAB. It also hard-counters the Ghost types that trouble Psychic teammates, since Normal immunity blanks their STAB. Build it when your team needs a win condition that doubles as a defensive backbone.

How to Build Your Own Water-Type Fusion

The ten fusions above are proven, but the real joy of Infinite Fusion is designing your own. Here is the quick recipe for building a water-type fusion that fits your team:

• Pick your role first. Sweeper? Put the fast, high-Attack Pokémon as the body (Attack and Speed lean 2/3 toward the body). Wall? Put the bulky special Pokémon as the head (HP, Special Attack, and Special Defense lean 2/3 toward the head).
• Engineer the typing. Remember: the fusion’s first type is the head’s primary type, and the second type is the body’s secondary type (or its primary type if it only has one). Want Water/Dragon? Use a Water-headed parent with a Dragon-bodied parent like Kingdra.
• Check both orders. Every pair makes two fusions, and the reversed version often has a completely different typing and stat spread. DNA Reversers cost ₽300 — experimenting is cheap.
• Mind the movepool. The fusion learns from both parents’ moves, so pair a Water parent with strong STAB (Hydro Pump, Waterfall, Ice Beam) with a partner that covers Water’s weaknesses to Electric and Grass.
• Preview before you commit. Run every candidate through our Pokémon Fusion Calculator to see exact stats, typing, and abilities for both orders before spending a Super Splicer.

Good Water-type donor parents to keep in your boxes: Gyarados, Blastoise, Starmie, Vaporeon, Kingdra, Suicune, Empoleon, and Lapras. With two or three of these ready, you can answer almost any team-building problem with a custom Water fusion. Browse the Infinite Fusion Dex to find where each one lives.

FAQ: Best Water-Type Fusions in Pokémon Infinite Fusion

What is the best water-type fusion in Pokémon Infinite Fusion?

Venustoise (Venusaur/Blastoise) is the best all-around water-type fusion for most players: Grass/Water typing, around 530 total base stats, excellent bulk on both sides, and strong STAB in Giga Drain and Hydro Pump. For pure offense, Gyaraizard (Gyarados/Charizard) with Dragon Dance is the hardest-hitting option.

What is the best water-type fusion for the Elite Four?

Venustoise and Slowgar are the two best story-mode picks. Both are buildable before the Elite Four, both wall large portions of Lorelei’s and Bruno’s teams, and both stay useful in postgame rematches. Vapoleon is the best budget option if you want a strong Water fusion early and cheap.

How do you get a Water/Dragon fusion?

Fuse a Water-headed Pokémon with a Dragon-bodied Pokémon whose secondary type is Dragon — Kingdra is the classic donor, since it is Water/Dragon itself. For example, a Blastoise head on a Kingdra body gives Water/Dragon. Always preview the result in the fusion calculator, because head/body order changes everything.

Are water-type fusions good for Nuzlocke runs?

Excellent. Water’s defensive profile — only two weaknesses and resistances to Fire, Water, Ice, and Steel — makes Water fusions some of the safest switch-ins in a Nuzlocke, where every lost Pokémon is permanent. Venustoise, Empolix, and Gyaralax are all top-tier Nuzlocke picks. See our Nuzlocke challenge guide for full rules and strategies.

Conclusion

The best water-type fusions in Pokémon Infinite Fusion share one trait: they take Water’s already-great defensive profile and fuse it with exactly the stats and coverage your team is missing. Start with Venustoise for an unkillable tank or Gyaraizard for a Dragon Dance sweeper, then experiment with the fusion calculator to design your own. Whatever you build, a Water fusion on your team is rarely the wrong answer.
