Formula Used
Use the IV order HP, Attack, Defense, Speed, Special Attack, and Special Defense.
Type bits use the least significant bit. Odd IVs count as 1. Even IVs count as 0.
Type Index = floor(((a + 2b + 4c + 8d + 16e + 32f) × 15) / 63)
Power bits use the second least significant bit. IV values with modulo 4 equal to 2 or 3 count as 1.
Base Power = floor(((u + 2v + 4w + 8x + 16y + 32z) × 40) / 63) + 30
The type index maps to Fighting, Flying, Poison, Ground, Rock, Bug, Ghost, Steel, Fire, Water, Grass, Electric, Psychic, Ice, Dragon, and Dark.
How to Use This Calculator
- Enter each IV from 0 to 31.
- Keep the stat order exactly as shown.
- Select the user types when you want a STAB check.
- Select target types when you want effectiveness guidance.
- Press the calculate button.
- Review the type, base power, category, and bit table.
- Use CSV or PDF export for records.
Understanding Gen 3 Hidden Power
Hidden Power is a unique move with hidden details in Generation 3. Its visible name stays the same. Its type and base power change with the six IV values. This makes it useful for coverage. It also makes it hard to plan without a clear calculator.
Why IV Bits Matter
Each IV has small binary patterns. The game reads the last bit of each IV to choose the move type. Odd IVs add type value. Even IVs add zero. The game then scales that sum into one of sixteen possible attacking types. Normal is not included. Fairy also does not exist in Generation 3.
The second last bit affects base power. IVs with remainders of two or three, after division by four, add power value. Other IVs add zero. The scaled total gives a base power from 30 to 70. Strong competitive sets usually aim for 70, but the needed pattern may reduce one or more perfect IVs.
How This Tool Helps
This calculator checks HP, Attack, Defense, Speed, Special Attack, and Special Defense in the correct order. It reports the Hidden Power type, base power, bit totals, move category, and practical notes. It also estimates STAB and target effectiveness when target types are supplied. This estimate is not a full battle damage formula. It is a quick planning measure.
Players can test breeding targets, compare trade candidates, and audit saved team files. A Grass result with 70 power may help Electric attackers. An Ice result may support coverage against Dragon and Ground targets. Fire, Water, and Electric results can also shape special attacking plans.
Best Planning Advice
Start with the desired type. Then adjust IV parity before chasing full perfection. When power matters, check each IV modulo four. A value of 30 can be better than 31 for some Hidden Power goals. Always confirm Speed needs first. Losing one Speed IV may matter more than gaining one coverage option.
Use the export buttons after each result. The CSV file helps spreadsheets. The PDF file creates a compact record for team notes, breeding logs, or emulator planning.
For best accuracy, enter final IVs after leveling, candies, or external IV checking. Small mistakes can change outputs.
FAQs
What does this calculator find?
It finds the Hidden Power type and base power from six Generation 3 IV values. It also shows bit totals, move category, STAB, and target effectiveness.
Which IV order should I use?
Use HP, Attack, Defense, Speed, Special Attack, and Special Defense. This order matters because each stat has a fixed weight in the formula.
Can Hidden Power be Normal type?
No. The Generation 3 Hidden Power type table excludes Normal. It also excludes Fairy, because Fairy type did not exist in that generation.
What is the highest base power?
The highest base power is 70. The lowest is 30. Your IV modulo 4 pattern controls the power result.
Why does 30 sometimes help?
An IV of 30 is even, but its second bit still adds power value. That can preserve 70 power while changing the Hidden Power type.
Is this a full damage calculator?
No. It estimates modified move power using STAB and type effectiveness. It does not include level, stats, items, weather, screens, or random damage rolls.
Why is category shown?
Generation 3 uses type-based physical and special categories. Hidden Power follows the category of its resulting type in this calculator.
Can I export my result?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a compact printable result summary.
