Use this Pokémon Infinite Fusion calculator to estimate fused base stats and fused typing in both directions: A head + B body and B head + A body.
| Base Stat | Pokémon A | Pokémon B |
|---|---|---|
| HP | ||
| Attack | ||
| Defense | ||
| Sp. Atk | ||
| Sp. Def | ||
| Speed |
Notes: This tool estimates base stats using the commonly referenced Infinite Fusion weighting formula. Final in-game performance also depends on level, nature, IVs, EVs, abilities, and moveset.
How this pokemon infinite fusion calculator works
In Pokémon Infinite Fusion, the same two Pokémon can create two different fusions depending on order. If Pokémon A is the head and Pokémon B is the body, you get one stat spread and one type result. Swap them, and you often get a very different outcome.
This calculator is designed to help you compare both forms quickly. Instead of manually checking stats every time, you can plug in base stats and instantly see which order is better for offense, defense, or speed control.
Fusion stat formula used
The calculator uses a weighted average model frequently used by the Infinite Fusion community:
- HP = floor((2 × Body HP + Head HP) / 3)
- Attack = floor((2 × Head Atk + Body Atk) / 3)
- Defense = floor((2 × Body Def + Head Def) / 3)
- Sp. Atk = floor((2 × Head SpA + Body SpA) / 3)
- Sp. Def = floor((2 × Body SpD + Head SpD) / 3)
- Speed = floor((2 × Head Spe + Body Spe) / 3)
Typing is estimated using a common rule of thumb: the fusion keeps the head’s primary type plus the body’s secondary type (or body primary if it has no secondary type).
How to use it effectively
1) Enter accurate base stats
Pull base stats from a trusted Pokédex source. Small mistakes can lead to choosing the wrong fusion direction.
2) Test both directions every time
Never assume one order is always better. A head/body swap can create huge changes in Attack, Speed, and bulk.
3) Match stats to team role
- Need a sweeper? Prioritize high Attack or Sp. Atk plus Speed.
- Need a tank? Look for strong HP, Defense, and Sp. Def totals.
- Need utility? Use type output to improve resistances and switch-ins.
Practical team-building tips
A powerful fusion is not always the one with the highest base stat total. Role fit matters more. For example, a slightly lower BST fusion with better defensive typing can outperform a glass cannon in longer battles.
Also compare both physical and special offense. Many players optimize only one side and forget that movepool and abilities may make the opposite build stronger in real matches.
FAQ
Is this an official game calculator?
No. This is a fan-made utility built for planning and quick comparison.
Why does my in-game stat look different?
In-game stats at a specific level include nature modifiers, IVs, EVs, and level scaling. This page focuses on base stat fusion math.
Can I use this for randomizer or custom rulesets?
Yes, as long as your ruleset follows similar head/body stat weighting. If your ROM settings change formulas, use this as a baseline estimate.
Final thoughts
If you are experimenting with Pokémon fusion combinations, this calculator can save a lot of time. Try fast comparisons, record your best head/body pairings, then test them in battle to see which fusion performs best in your actual strategy.
