Introduction
The Pokemon Infinite Fusion Calculator lets you combine any two Pokémon into one. Pick a Head Pokémon and a Body Pokémon, then hit Fuse to see what you get. The tool calculates your fusion's base stats, types, abilities, and move pool using the same formulas as the Pokémon Infinite Fusion fan game.
The Head Pokémon controls Sp. Atk, Sp. Def, and Speed. The Body Pokémon controls HP, Attack, and Defense. Each fused stat uses a 2/3 dominant + 1/3 recessive split, so the Pokémon in the dominant role has a bigger impact on that stat. You can swap the Head and Body at any time to see how the fusion changes.
You can also compare both fusion orientations side by side, view a full stat bar chart, and read a step-by-step breakdown that shows exactly how every number is calculated. Whether you are planning a team or just want to experiment, this calculator gives you fast and accurate fusion results for all Gen 1 Pokémon. For a deeper look at individual stat spreads before fusing, try our Pokemon Stat Calculator.
How to Use Our Pokémon Infinite Fusion Calculator
Pick two Pokémon below to fuse them together. The calculator will show you the fusion's name, types, base stats, abilities, and full move pool in seconds.
Head Pokémon: Type a Pokémon name or Pokédex number into the Head field. The Head controls the fusion's Sp. Atk, Sp. Def, and Speed stats. It also sets the primary type.
Body Pokémon: Type a Pokémon name or Pokédex number into the Body field. The Body controls the fusion's HP, Attack, and Defense stats. It also sets the secondary type.
Fuse Button: Click "Fuse!" after you pick both Pokémon. This runs the fusion formula and shows your full results.
Swap Button: Click "Swap" to switch your Head and Body Pokémon with each other. This lets you quickly see how the fusion changes when the roles are reversed.
Random Button: Click "Random" to pick two Pokémon at random and fuse them right away. This is a fun way to discover new combinations.
Reset Button: Click "Reset" to clear your choices and return the calculator to its default state.
Compare Both Orientations: Turn on this toggle to see both fusion directions side by side. This helps you find which orientation gives better stats.
What Is Pokémon Infinite Fusion?
Pokémon Infinite Fusion is a fan-made game built on top of Pokémon FireRed. It lets you combine any two Pokémon into one brand-new creature. The fused Pokémon gets a mixed sprite, combined stats, shared abilities, and a new name made from both parents. With 151 original Pokémon in the base set, there are over 22,000 possible fusions to try — a number you can verify with a Combination Calculator.
How Fusion Stats Work
Every fusion has a Head Pokémon and a Body Pokémon. Each one controls different stats. The Body controls HP, Attack, and Defense. The Head controls Special Attack, Special Defense, and Speed. The dominant Pokémon gives two-thirds of the stat, and the other gives one-third. This means swapping the Head and Body creates a different fusion with different strengths. If you want to check how individual values affect a Pokémon's final numbers outside of fusion, our Pokemon IV Calculator can help.
How Fusion Types Work
The fused Pokémon takes its first type from the Head Pokémon's primary type. It takes its second type from the Body Pokémon's secondary type. If the Body has no secondary type, it uses the Body's primary type instead. If both types end up the same, the fusion becomes a single-type Pokémon. Understanding how types interact is key to building a strong fusion — our Pokemon Type Calculator shows you every weakness, resistance, and immunity for any type combination.
How Fusion Names Work
The fusion's name is a mix of both Pokémon names. It takes the first half of the Head Pokémon's name and the last half of the Body Pokémon's name, then joins them together. For example, fusing Charizard (Head) with Blastoise (Body) gives you "Chartoise."
Abilities and Moves
A fused Pokémon can use abilities from both the Head and Body Pokémon. It also learns moves from both parents based on their types. This means fusions often have a bigger move pool and more ability options than either parent alone, which opens up many new battle strategies. To see how much damage your fusion's moves can actually deal, run the numbers through our Pokemon Damage Calculator. You can also use the Pokemon Catch Rate Calculator to figure out your odds of catching the base Pokémon you need before fusing, and check our Shiny Odds Calculator if you are hunting for rare variants along the way.
