        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.1 Each Pokémon's base stats, types and abilities are the ones the game stores for it.7

        The Head Pokémon controls HP, Sp. Atk, and Sp. Def. The Body Pokémon controls Attack, Defense, and Speed.1 Each fused stat takes two thirds of the dominant Pokémon's value plus one third of the other's, each rounded down, so the Pokémon in the dominant role has a bigger impact on that stat.1 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. This calculator gives you fast and accurate fusion results for all Gen 1 Pokémon.

        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.

        Head Pokémon: Type a Pokémon name or Pokédex number into the Head field. The Head controls the fusion's HP, Sp. Atk, and Sp. Def stats. It also sets the primary type.1

        Body Pokémon: Type a Pokémon name or Pokédex number into the Body field. The Body controls the fusion's Attack, Defense, and Speed stats. It also sets the secondary type.1

        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 Pokémon game built with RPG Maker XP.5 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.1 The full game has 501 Pokémon to fuse.3 This calculator covers the 151 Gen 1 Pokémon, which make over 22,000 possible fusions.

        How Fusion Stats Work

        Every fusion has a Head Pokémon and a Body Pokémon. Each one controls different stats. The Head controls HP, Special Attack, and Special Defense. The Body controls Attack, Defense, and Speed.1 The dominant Pokémon gives two thirds of the stat and the other gives one third, each rounded down.1 This means swapping the Head and Body creates a different fusion with different strengths.

        How Fusion Types Work

        The fused Pokémon takes its first type from the Head Pokémon's primary type, except that a Normal/Flying Head gives Flying.1 It takes its second type from the Body Pokémon's secondary type, or from the Body's primary type when the secondary one matches the first type.1 If the Body has no secondary type, it uses the Body's primary type instead.4 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. The game splits every Pokémon's name into a front part and a back part, and the fusion takes the Head's front part and the Body's back part.2 For example, fusing Charizard (Head) with Blastoise (Body) gives you "Chartoise."

        Abilities and Moves

        A fused Pokémon can take its ability from either the Head or the Body Pokémon.1 In the game, you choose which ability it keeps when you fuse.6 It can also learn moves from both parents.1 This means fusions often have a bigger move pool and more ability options than either parent alone, which opens up many new battle strategies.

        Formulas used

        Body-Governed Fusion Stat (Attack, Defense, Speed) 1
        \text{Stat}_{\text{fusion}} = \left\lfloor \frac{2 \times \text{Stat}_{\text{body}}}{3} \right\rfloor + \left\lfloor \frac{\text{Stat}_{\text{head}}}{3} \right\rfloor
        Head-Governed Fusion Stat (HP, Sp. Atk, Sp. Def) 1
        \text{Stat}_{\text{fusion}} = \left\lfloor \frac{2 \times \text{Stat}_{\text{head}}}{3} \right\rfloor + \left\lfloor \frac{\text{Stat}_{\text{body}}}{3} \right\rfloor
        Base Stat Total
        \text{BST} = \text{HP} + \text{Atk} + \text{Def} + \text{SpAtk} + \text{SpDef} + \text{Spe}

        Frequently asked questions

        What is the fusion stat formula?

        Each fused stat equals ⌊2 × dominant ÷ 3⌋ + ⌊recessive ÷ 3⌋.1 The Head is dominant for HP, Sp. Atk, and Sp. Def. The Body is dominant for Attack, Defense, and Speed.1 The floor function rounds each part down to a whole number.

        Does swapping Head and Body change the fusion?

        Yes. Swapping changes which Pokémon controls which stats, so the fusion gets different base stats, a different name, and possibly different types. Use the Swap button or turn on Compare Both Orientations to see both versions side by side.

        Why is my fusion sprite missing?

        Not every fusion has a custom sprite. The calculator tries to load a community-made sprite first, then an auto-generated one. If neither exists, you will see a "Sprite not available" placeholder. The stats and data are still fully accurate.

        How is the fusion name created?

        The calculator uses the game's own list of name parts: the Head's front part plus the Body's back part.2 If the front part ends with the letter the back part starts with, that letter appears once.1

        Can a fusion be a single type?

        Yes. If the Body has only one type and it matches the Head's primary type, the fusion becomes a mono-type Pokémon.1

        Which Pokémon decides the primary type?

        The Head Pokémon's primary type becomes the fusion's first type, except that a Normal/Flying Head gives Flying.1 The Body Pokémon provides the second type.

        Which Pokémon decides the secondary type?

        The fusion's second type comes from the Body Pokémon's secondary type. If the Body has no secondary type, its primary type is used instead.4 The primary type is also used when the Body's secondary type matches the first type.1

        How are fusion abilities chosen?

        The fusion can take any ability from either parent.1 In the game, you choose which ability it keeps when you fuse.6 If both the Head and Body share the same ability, it appears once and is labeled "Both."

        How is the fusion move pool built?

        The calculator combines moves from both Pokémon based on their types, plus a set of universal moves like Tackle and Body Slam. Each move is tagged to show if it comes from the Head, Body, or Both.

        What is Base Stat Total (BST)?

        BST is the sum of all six base stats: HP, Attack, Defense, Sp. Atk, Sp. Def, and Speed. A higher BST usually means a stronger Pokémon overall.

        Are the fusion results the same as in the Pokémon Infinite Fusion game?

        This calculator uses the same 2/3 + 1/3 stat formula and the same type-inheritance rules as the fan game.1 It also uses the base stats, types and abilities the game stores for each Pokémon.7 The move pool is simplified. For exact in-game move sets, check the game's Pokédex.

        What do the up and down arrows next to each fused stat mean?

        They show how the fused stat compares to the simple average of both parents. A green up arrow means the fusion stat is above average. A red down arrow means it is below average.

        How many total fusions are possible with 151 Pokémon?

        Since order matters (Head vs. Body), there are 151 × 150 = 22,650 possible fusions. Each pair of Pokémon can produce two different fusions depending on which one is the Head.
