Best Fusions for Nuzlocke Challenge in Pokémon Infinite Fusion

A Nuzlocke in Pokémon Infinite Fusion is a completely different beast from a Nuzlocke in any official Pokémon game. Permadeath still applies, you still catch only the first encounter per route — but every Pokémon you catch is also fusion material, and the right fusion can turn a mediocre encounter into a run-saving monster. This guide covers the best fusions for a Nuzlocke challenge in version 6.7.2: which combinations keep you alive, which roles they fill, and which traps to avoid.

This is a fan-written guide based on how the game actually works. Nothing here requires cheats or exploits — just smart team building with the fusion mechanics the game gives you.

Nuzlocke Rules, Adapted for Infinite Fusion

The classic Nuzlocke rules still form the foundation:

• Permadeath: if a Pokémon faints, it is dead — box it permanently. In Infinite Fusion this is brutal, because a fused Pokémon’s death costs you both parents.
• First encounter per route: you may only catch the first Pokémon you encounter on each route or area. Fusions you build yourself do not count as encounters.
• Nicknames: name everything. It hurts more when they die, which is the point.

Fusion adds decisions the classic rules never had to handle. Most players use these house rules:

• Fusion is allowed, but a fused Pokémon is one life. If your Charizard/Blastoise fusion faints, both halves are gone. This makes every fusion a real gamble — which is exactly why this guide exists.
• Dupes clause counts species, not fusions. If you already own a Pidgey, you may re-roll the encounter — but a Pidgey fused with something new is still just a Pidgey for dupes purposes. Decide this with yourself before the run starts.
• Gift and static Pokémon count as their area’s encounter. The game hands you incredible gifts — Lapras, Eevee, Snorlax, the Hitmonlee/Hitmonchan choice. Most Nuzlockers allow one gift per area, and these gifts are the backbone of a winning run.

Why Fusions Change Nuzlocke Strategy Completely

In a normal Nuzlocke, you are stuck with whatever the route gives you. In Infinite Fusion, you are stuck with whatever the route gives you plus the ability to combine any two of them. That changes everything:

• Weakness patching: a fusion inherits traits from both parents, so you can erase a Pokémon’s crippling 4x weakness by fusing it with something that resists that type. A Rock-weak Fire type fused with a bulky Water or Steel body suddenly stops fearing Rock Slide.
• Stat averaging: a fusion’s stats are roughly the average of both parents. Fusing a frail sweeper with a bulky tank produces something fast enough and bulky enough — the exact profile that survives Nuzlockes.
• Coverage on demand: need an Electric move for Misty? An Ice move for Lance? Fuse for it instead of praying the route gives you the right encounter.

The golden rule of Nuzlocke fusions: bulk beats power. A sweeper that OHKOs everything but dies to one super-effective hit will eventually roll the wrong matchup. A bulky fusion that takes hits and grinds out wins survives the whole run. Build for the worst case, not the best case.

The Best Nuzlocke Fusions by Role

Tanks: Your Run Insurance

Every winning Nuzlocke team has at least one near-unkillable wall. These fusions are the safest investments in the game:

• Snorlax + Steelix: the ultimate physical wall. Snorlax’s colossal HP averaged with Steelix’s absurd Defense creates a fusion that shrugs off physical attackers all game. Give it Rest or reliable recovery and it walls entire gyms.
• Snorlax + Aggron: similar idea with a different flavor — monstrous HP plus Steel/Rock bulk. Watch out for Fighting and Ground coverage, but very little else threatens it.
• Steelix + anything bulky: Steelix is arguably the single best defensive fusion parent in the game. Its Defense is so high that even averaged with a mediocre partner, the result is still a wall. Steelix + Vaporeon gives you a mixed wall with Wish support potential.
• Blissey/Chansey + Steel type: if you are lucky enough to catch the pink wall, fusing it with a Steel body patches its Defense while keeping the HP. This is a legitimately run-defining fusion.

Sweepers: Fast, Strong, and (Barely) Safe

Sweepers win battles quickly, which means fewer turns for something to go wrong. The best Nuzlocke sweepers pair huge offense with just enough bulk or speed to avoid taking hits:

• Gengar + Alakazam: blistering Speed and Special Attack from both sides. It will not take a hit, but almost nothing gets to move first against it. The classic glass cannon — use it to delete threats, then switch out.
• Dragonite + fast physical attacker: Dragonite’s bulk and movepool averaged with something like Aerodactyl or Jolteon gives you a fast, hard-hitting Dragon that can actually survive a hit. Dragonite fusions are Nuzlocke gold because the base is already so well-rounded.
• Machamp + bulky Fighting partner: No Guard Dynamic Punch confusion is as broken in a Nuzlocke as anywhere else. Fusing Machamp with something bulky like Hariyama gives you a confusion-spreading tank that disrupts entire teams.
• Starter + starter fusions: fusing two starters (for example, your Fire starter with a Water starter) gives you an early-game powerhouse with dual STAB coverage that carries the first half of the run. You only get one starter per playthrough, but trades and gifts can supply the second half.

Utility and Coverage Fusions

Nuzlockes are lost to specific threats — a gym leader’s ace, a rival’s coverage move. These fusions exist to answer problems:

• Gyarados + anything: Intimidate plus Water/Flying coverage makes Gyarados one of the best defensive pivots in the game. Fusing it with a bulky partner gives you a switch-in for half the game’s physical threats. Magikarp is a guaranteed catch with the Old Rod, making this one of the most reliable fusions in any Nuzlocke.
• Electric coverage fusions: Ampharos, Electabuzz, or Jolteon fused with a bulky body give you the Electric coverage the mid-game demands (Misty, flying types, water routes) without the frailty of a pure Electric type.
• Lapras + bulky Water partner: Lapras is a guaranteed gift, and it is already a perfect Nuzlocke Pokémon — huge HP, great typing, learns Ice and Water coverage naturally. Fusing it with something like Vaporeon or Slowbro makes it even harder to kill.
• Eevee-line fusions: the Celadon gift Eevee can become any Eeveelution, and each one is premium fusion material. Vaporeon for bulk, Jolteon for speed, Espeon for special sweeping — pick the one your team is missing and fuse accordingly.

Gift Pokémon: Your Guaranteed Nuzlocke Core

Infinite Fusion is generous with gift and static Pokémon, and in a Nuzlocke these are pure gold — guaranteed encounters you can plan around. Build your run around them:

• Lapras (Silph Co. gift) — as above, a perfect Nuzlocke Pokémon and elite fusion parent.
• Eevee (Celadon gift) — the most flexible gift in the game. Evolve it into whatever your team lacks.
• Snorlax (static encounters) — the best HP stat to fuse with anything. Even unfused, it walls special attackers.
• Hitmonlee / Hitmonchan (Fighting Dojo gift) — a guaranteed strong Fighting type for the mid-game, excellent fusion material for coverage.
• Your starter — never fuse your starter recklessly early. It is usually your strongest Pokémon for the first three gyms; fuse it only when you have a clear upgrade path planned.

Before fusing any gift Pokémon, preview the result in the Fusion Tool — check the typing, the averaged stats, and the movepool. A gift is irreplaceable; a bad fusion of a gift is a run-ending mistake.

Fusions to Avoid in a Nuzlocke

Not every cool fusion is a safe fusion. Avoid these traps:

• Double glass cannons: fusing two frail sweepers (like Alakazam + Jolteon) gives you something fast that dies to any priority move or a single mispredicted switch. One of your sweepers should always have a defensive backbone.
• 4x-weakness fusions: if the fusion ends up with a 4x weakness to a common attacking type (Rock, Ice, Fighting), one critical hit can end your run. Always check the defensive typing before committing — the Fusion Calculator helps you verify coverage and weaknesses.
• Slow setup sweepers: fusions that need multiple turns of setup (Swords Dance, Dragon Dance) to function are liabilities. Nuzlocke battles punish setup turns harshly — a critical hit during your second Dragon Dance ends the run.
• Fusing your only answer to a threat: if your Electric type is the only thing stopping Misty’s Starmie, do not fuse it into something that loses Electric STAB right before Cerulean Gym. Time your fusions around upcoming boss fights.

A Sample Nuzlocke-Safe Team Core

Here is an example core that covers the whole game. Adapt it to whatever encounters you actually get:

• Physical wall: Snorlax + Steelix (or Aggron). Absorbs physical hits all game.
• Special wall / pivot: Lapras fusion or Blissey + Steel type. Handles special attackers and provides switch-in safety.
• Fast sweeper: Gengar + Alakazam or a Dragonite fusion. Deletes threats before they move.
• Utility pivot: Gyarados fusion with Intimidate. Switches into physical attackers for free and threatens back.
• Coverage slot: whatever your team is missing — Electric, Ice, or Fighting coverage fused onto a bulky body.
• HM / flex slot: every Nuzlocke needs Cut, Surf, Strength and Flash carriers. Fuse HM utility onto bulky Pokémon so the slot is not dead weight in boss fights.

Nuzlocke Tips Specific to Infinite Fusion

• Don’t fuse early and often. Every fusion is irreversible without cost, and fusing two decent Pokémon into one mediocre fusion halves your roster. Fuse with a plan, not for fun.
• Keep unfused backups. Before fusing your only counter to an upcoming gym, catch and train a backup. If the fusion faints, you need a replacement immediately.
• Check abilities. Always verify which ability your fusion ends up with before relying on it in a boss fight. An Intimidate you counted on that didn’t carry over is how runs die.
• Respect the level curve. Infinite Fusion’s bosses hit hard and the level curve is unforgiving. Grind to at least the gym leader’s ace level before every major fight — overleveling slightly is not cheating, it is surviving.
• Triple fusions are a luxury, not a plan. They are powerful but expensive to build and their death costs three Pokémon. Save them for the post-game unless your run is already dominant. (See our Infinite Fusion Dex for what is even possible.)

Frequently Asked Questions

Can you do a Nuzlocke in Pokémon Infinite Fusion?

Absolutely — the game is fully playable as a Nuzlocke, and the fusion mechanic makes it one of the most interesting Nuzlocke experiences in any Pokémon game. Just agree on fusion house rules (one life per fusion, dupes clause counting species) before you start.

What is the best starter for a Nuzlocke in Infinite Fusion?

Bulky starters with good mid-game matchups perform best. Water starters generally have the smoothest early game thanks to favorable matchups against the first few gyms. Whatever you pick, avoid fusing your starter until you have a clear upgrade planned — it is usually your strongest Pokémon for the first half of the run.

What happens when a fusion faints in a Nuzlocke?

By the standard house rules, the fusion counts as a single Pokémon — so both parent Pokémon are considered dead. This is what makes fusion decisions so tense: every fusion risks two team members at once. Never fuse anything you cannot afford to lose.

Are triple fusions allowed in Nuzlockes?

Most players allow them but treat them as the ultimate high-risk play — one faint costs three Pokémon. They are better suited to post-game challenge runs than to a first Nuzlocke attempt.

Which is more important in a Nuzlocke: offense or bulk?

Bulk, by a wide margin. Sweepers win battles faster, but walls survive the one bad matchup, the one critical hit, the one mispredicted switch that ends runs. Build your core around tanks, then add exactly as much offense as you need.

Conclusion

The best fusions for a Nuzlocke challenge are not the flashiest ones — they are the ones that refuse to die. Snorlax and Steelix walls, Gyarados pivots, guaranteed gift Pokémon like Lapras and Eevee, and exactly one fast sweeper to delete what the walls cannot. Plan every fusion before you commit, check typing and abilities, keep backups, and respect the level curve.
