Fusion Count Calculator
Estimate how many possible Pokémon fusion combinations exist based on your selected dex size and rules.
What this Pokémon Infinite Fusions calculator does
This tool helps you quickly estimate the number of possible fusion combinations in a Pokémon Infinite Fusion style ruleset. Instead of manually counting pairs, you can choose how combinations should be treated and get totals instantly.
The key question is whether you want to count directional pairs separately. In many fan projects, combining Pokémon A as the head with Pokémon B as the body can produce a different result than swapping them. That is why this calculator supports both ordered and unordered counting.
How the formulas work
1) Ordered combinations
Ordered mode treats A+B and B+A as different entries.
- Without self fusions: n × (n - 1)
- With self fusions: n × n
2) Unordered combinations
Unordered mode treats A+B and B+A as the same pair.
- Without self fusions: n × (n - 1) ÷ 2
- With self fusions: n × (n + 1) ÷ 2
Why this is useful for players
- Plan challenge runs around a limited roster.
- Estimate how many combinations remain unexplored.
- Track your progress as your available species count grows.
- Compare “full dex potential” vs. your current collection.
Quick planning tips
Start with a target pool
If you only want high-quality options, pick a subset (for example 60–100 species) and calculate that first. A smaller list makes testing and team building far easier.
Use ordered mode for sprite hunting
If your goal is to find unique visual outcomes, ordered mode is usually better because directional swaps often matter.
Use unordered mode for rough strategy totals
If you only care about pair concepts and not direction, unordered mode gives a cleaner high-level estimate.
FAQ
Does this calculator use a live game database?
No. It is a math-based fusion count calculator. It does not verify whether any specific sprite exists in your install.
What should I enter for species count?
Enter the number of species available in your current game setup, patch, or challenge rules. You can also use your personal caught/owned count for a progress snapshot.
Are self fusions real combinations?
That depends on your rules. Some players include them for completion totals; others exclude them as duplicates. This tool lets you decide.
