Formula Used
Type Formula
Attack remainder = Attack DV mod 4. Defense remainder = Defense DV mod 4.
Type index = 4 × Attack remainder + Defense remainder.
The index selects this order: Fighting, Flying, Poison, Ground, Rock, Bug, Ghost, Steel, Fire, Water, Grass, Electric, Psychic, Ice, Dragon, Dark.
Power Formula
Special remainder = Special DV mod 4. Speed remainder = Speed DV mod 4. Defense remainder = Defense DV mod 4.
Power core = ((Special remainder × 4 + Speed remainder) × 5) + Defense remainder.
Base power = floor(Power core ÷ 2) + 31.

Hidden Power in Generation Two
Hidden Power is a special move with secret values. In Generation Two, its type and base power come from DVs. DVs are small hidden numbers. They run from zero to fifteen. The game reads their final two bits. Those bits create the move type. More bits create the base power.
Why DVs Matter
Attack and Defense DVs choose the type. The calculator takes each value modulo four. That keeps only the last two bits. The Attack remainder is multiplied by four. The Defense remainder is added. The final number selects one of sixteen types. Fighting starts at zero. Dark ends at fifteen.
Power Logic
Power uses Special, Speed, and Defense remainders. Special is weighted highest. Speed is next. Defense adds a small final shift. The formula returns values from thirty one to seventy. A perfect set of fifteen DVs gives Hidden Power Dark with seventy base power.
Advanced Planning
This tool is useful for battle planning. You can test exact DVs before training. You can also compare the output with a target type. The target check helps breeders and players see whether a spread is worth keeping. A high power result is not always best. A lower power move may cover a key weakness.
Practical Notes
Generation Two uses one Special DV. It affects both Special Attack and Special Defense. Later games use IVs in a different way. So do not use modern Hidden Power formulas for older cartridges. Enter DVs only from zero to fifteen. If you know IVs from another generation, convert carefully before using them.
Exporting Results
The export buttons save your result for later review. CSV is good for spreadsheets. PDF is good for quick notes. The example table shows common spreads and expected outputs. Use it to check that your entries feel correct. After submitting the form, the result appears above the calculator. That keeps the answer easy to see while you adjust DVs.
Reading the Output
The result panel lists the type, power, selector values, and target status. It also explains the remainders. These details make mistakes easier to find. Change one DV at a time when searching. Small changes can move the type quickly during repeated team tests.
FAQs
What is a DV?
A DV is a hidden value used in older games. In Generation Two, each main DV ranges from 0 to 15. This calculator uses those values to find Hidden Power type and base power.
Does this use modern IV formulas?
No. This page is only for Generation Two mechanics. Modern Hidden Power calculations use different IV rules, so their results should not be mixed with this formula.
Which DVs control Hidden Power type?
Attack and Defense DVs control the type. The calculator keeps their remainders after division by four. Those two remainders create the type index.
Which DVs control base power?
Special, Speed, and Defense DVs control base power. Special has the largest weight. Speed has the next weight. Defense adjusts the final value slightly.
What is the highest possible base power?
The highest possible base power is 70. A spread with DVs of 15 in Attack, Defense, Speed, and Special gives Hidden Power Dark with 70 power.
What is the lowest possible base power?
The lowest possible base power is 31. It appears when the relevant remainders used in the power formula are all zero.
Why is there one Special DV?
Generation Two uses one Special DV. That value relates to both special attacking and special defending stats. Later games split these ideas differently.
Can I export the result?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a cleaner saved note. Both options use the calculated result shown above the form.
