Calculate your USUM Hidden Power
Use the formula order: HP, Attack, Defense, Speed, Special Attack, Special Defense.
Hidden Power type index scale
The active card matches the calculated result. The index follows the Gen III–VII formula.
Sample IV spreads
| HP | Atk | Def | Spe | SpA | SpD | Parity sum | Result |
|---|---|---|---|---|---|---|---|
| 31 | 31 | 31 | 31 | 31 | 31 | 63 | Dark |
| 31 | 30 | 31 | 30 | 30 | 31 | 37 | Fire |
| 31 | 30 | 31 | 31 | 31 | 31 | 61 | Ice |
| 31 | 31 | 30 | 30 | 30 | 30 | 3 | Fighting |
Type calculation
For each IV, use 1 when the IV is odd. Use 0 when it is even.
Weighted parity sum = HP + 2×Attack + 4×Defense + 8×Speed + 16×Special Attack + 32×Special DefenseType index = floor((weighted parity sum × 15) / 63)
Index 0 is Fighting and index 15 is Dark. In Ultra Sun and Ultra Moon, Hidden Power always has 60 base power and is special.
Check a spread before breeding
- Enter the six IV values in the displayed formula order.
- Add an optional target type to compare breeding parity.
- Add your Pokémon’s types to check same-type attack bonus.
- Select the Normalium Z option only for that battle plan.
- Calculate, then export the result as CSV or PDF.
Planning Hidden Power in Gen VII
Hidden Power needs careful preparation. In Ultra Sun and Ultra Moon, six IVs influence its battle type. Their parity matters. Only each final parity bit is ever used. A value of 31 is odd. A value of 30 is even. This makes breeding targets easier to describe. Seek 31 values for odd requirements. Seek 30 values for even requirements. The move can supply coverage your Pokémon otherwise lacks. It may punish common switch-ins. However, the desired type can reduce one IV by one point. That cost matters for Speed, Attack, or defenses. Review the full spread before accepting an egg.
Reading the weighted parity formula
The Gen VII calculation uses six weighted parity bits. HP adds one point when odd. Attack adds two. Defense adds four. Speed adds eight. Special Attack adds sixteen. Special Defense adds thirty-two. Add active values. Multiply the sum by fifteen. Divide by sixty-three. Then round down. The final number selects one type from Fighting through Dark. Normal and Fairy cannot result. In these games, move power is always 60. A second power calculation is unnecessary. Hidden Power is special. Use Special Attack when estimating damage.
Using targets without losing track
Enter legal IVs from zero through 31. The calculator reports type, weighted parity sum, and index. Select an optional target before calculating. The page finds a nearby legal parity profile. It needs the fewest parity changes from current IVs. Its high-IV template uses 31 for odd slots. It uses 30 for even slots. This is a breeding guide, not a guarantee. Eggs, inheritance, Destiny Knot, and Hyper Training need separate planning. Hyper Training does not rewrite underlying IV data. It does not change Hidden Power's type. Keep original IVs carefully when checking this move.
Exporting a complete result
Matching a user type earns same-type attack bonus. Enter one or two types to check it. This feature checks matching only. It does not calculate resistances, weather, items, abilities, terrain, or damage rolls. Normalium Z can convert the move into Breakneck Blitz. The page shows its standard 120 base power reminder. Use that option only for relevant Gen VII battles. Export the result as CSV for breeding notes. Create a PDF summary for folders or trade records. Save IV order with every export. The formula order is HP, Attack, Defense, Speed, Special Attack, then Special Defense. That order prevents type mistakes.
Hidden Power USUM FAQs
1. Does Hidden Power use exact IV values?
Only odd or even parity changes the type. A 31 and a 1 act the same for that stat’s type bit. Exact IV values still matter for stats, so high-IV templates usually use 31 for odd requirements and 30 for even requirements.
2. What is Hidden Power’s base power in USUM?
It is always 60 in Ultra Sun and Ultra Moon. Earlier generations used a separate IV-based power calculation. That calculation is not used for Gen VII Hidden Power.
3. Is Hidden Power physical or special in USUM?
It is special. Use the Pokémon’s Special Attack and the target’s Special Defense when estimating damage. The resulting Hidden Power type does not change its special category.
4. Can Hidden Power become Fairy-type?
No. The Gen VII method can produce sixteen types from Fighting through Dark. Normal and Fairy are excluded from the possible results.
5. Why do many spreads use 30 instead of 31?
Thirty is even, while 31 is odd. A desired Hidden Power type may require an even parity bit. Using 30 keeps the IV high while meeting that requirement.
6. Does Hyper Training change Hidden Power?
No. Hyper Training improves battle-stat treatment, but it does not rewrite the underlying IV values used by Hidden Power. Check the original IV parity pattern.
7. Does STAB apply to Hidden Power?
Yes, when the calculated Hidden Power type matches one of the user’s own types. The calculator only checks that direct type match. It does not model other damage modifiers.
8. Can I use a 0 IV for a required even slot?
Yes for the Hidden Power type formula, because zero is even. It is normally weaker for the actual stat. Use 30 unless a deliberate low-stat strategy needs another even value.
9. What does the target template mean?
It is a nearby parity pattern that creates your selected type. The template uses 31 for odd slots and 30 for even slots. It is a practical high-IV reference, not a guaranteed breeding outcome.
10. What does Normalium Z do here?
In the relevant Gen VII context, Hidden Power can become Breakneck Blitz when paired with Normalium Z. This page shows its 120 base power reminder. Plan type interactions separately.
11. Why is the IV order important?
The weights are assigned to a fixed order: HP, Attack, Defense, Speed, Special Attack, and Special Defense. Changing the order changes the weighted sum and can produce the wrong Hidden Power type.
