Tie-break note

Nearest breeding power tie: Robinquill (1020), Felbat (1010). Robinquill wins because it appears earlier in the game's internal order.

Current Calculation

Breeding power average

floor((570 + 1460 + 1) / 2) = 1015. The closest valid breeding power result is Robinquill (1020).

Use Scenarios

Check a parent pair before breeding

Pick two species to see whether the child comes from the standard breeding power average, a fixed special combo, or a gender-dependent exception.

Work backward from a target child

Use the reverse pair list when you already know the Pal you want and need alternative parent routes instead of guessing combinations one by one.

Verify a known variant shortcut

Use the calculator as a quick confirmation layer for famous combos such as Mossanda plus Rayhound or the Wixen and Katress gender split before you commit resources.

Formula Explanation

1) Same-species shortcut

same species + same species -> same species

If both parents are the same Pal species, the calculator returns that species immediately instead of running the normal midpoint search.

2) Special combo override

fixed pair -> fixed child

Named special combinations bypass the normal breeding power average. When one of those pairs is detected, the fixed child is shown as the result.

3) Standard breeding power rule

target = floor((power1 + power2 + 1) / 2)

For ordinary pairs, the game uses the midpoint breeding power target and then maps that target to the nearest valid child in the standard breeding pool.

4) Tie-break and variant handling

nearest power -> lower internal index -> non-variant first

If several candidates are equally close, the internal order resolves the tie. Special-combo children are excluded from the normal nearest-power pool so they do not appear by accident.

How to Read the Result

Method label

This tells you whether the answer came from the same-species rule, a special combo override, a standard breeding power average, or a gender-dependent exception.

Target power

For ordinary pairs, target power is the midpoint the game tries to hit before choosing the nearest valid child. It is not always equal to the child power shown in the result.

Other parent pairs

This count shows how many other combinations in the current data set also produce the same child, which is useful when you want backup breeding paths.

Gender-dependent output

If the pair has a male and female exception, the calculator shows both possible children so you can decide which parent needs each gender.

Example Cases

Case 1: Standard midpoint result with a tie-break

Inputs

  • Parent 1: Anubis (570)
  • Parent 2: Cattiva (1460)

Computed Results

  • Method: Breeding power average
  • Formula trace: floor((570 + 1460 + 1) / 2) = 1015. The closest valid breeding power result is Robinquill (1020).
  • Offspring: Robinquill (1020)
  • Target power: 1015
  • Tie-break: Nearest breeding power tie: Robinquill (1020), Felbat (1010). Robinquill wins because it appears earlier in the game's internal order.
  • Other parent pairs in current data: 239

Interpretation

This pair uses the normal breeding power rule. The target is 1015, and the nearest candidates sit on both sides of that midpoint, so internal order resolves the tie in favor of Robinquill.

Decision Hint

Use this kind of result when you want to understand why a child is close to the midpoint rather than expecting the midpoint itself to appear as an exact breeding power match.

Case 2: Fixed special combo override

Inputs

  • Parent 1: Mossanda (430)
  • Parent 2: Rayhound (740)

Computed Results

  • Method: Special combo override
  • Formula trace: Mossanda + Rayhound is a fixed special combination, so it bypasses the normal breeding power average and produces Grizzbolt.
  • Offspring: Grizzbolt (200)
  • Other parent pairs in current data: 1

Interpretation

This pair is a named exception, so the game skips the normal midpoint search and returns Grizzbolt directly. The reverse pair count also shows that Grizzbolt has at least one other breeding route in the current data set.

Decision Hint

When a pair is widely known as a shortcut, trust the special combo label instead of trying to reason from parent breeding powers alone.

Case 3: Gender-dependent variant result

Inputs

  • Parent 1: Wixen (1160)
  • Parent 2: Katress (700)

Computed Results

  • Method: Gender-dependent variant
  • Formula trace: Wixen + Katress has two special outcomes. The child depends on which parent is male or female.
  • Female Wixen + Male Katress -> Wixen Noct (1150)
  • Male Wixen + Female Katress -> Katress Ignis (690)

Interpretation

This pair has two different fixed children depending on which parent is male or female. Showing both outputs is more accurate than forcing a single answer for a gender-sensitive exception.

Decision Hint

Use the pair only when you can control the sex assignment of both parents; otherwise you may breed for the wrong variant.

Boundary Conditions

The calculator predicts child species only. It does not score passive inheritance quality, IVs, alpha traits, or incubation temperature timing.
Special combos override the normal breeding power average, so a famous pair can produce a child that ignores the midpoint target entirely.
The Wixen and Katress pair is handled as a gender-dependent exception, which means one male and one female are assumed and the sex assignment matters.
Same-species breeding is treated as a direct same-species result instead of a midpoint lookup.
Reverse pair suggestions come from the current local data snapshot and are capped in the UI, so the page shows representative alternatives rather than every possible line at once.
Future Palworld updates can change breeding powers, special combos, or tie-break order, so recheck results after major content patches.

Frequently Asked Questions

How does this calculator choose the child species for a normal pair?
For a normal pair, the calculator averages the two breeding power values with floor((power1 + power2 + 1) / 2), then finds the nearest valid child in the normal breeding pool. If a fixed special combo exists, that override is used instead of the average.
Why do two copies of the same Pal return the same species?
The game uses a same-species shortcut for identical parents, so breeding one species with itself returns that same species instead of running the normal nearest-power search.
Why does Wixen plus Katress show two possible children?
That pair is a gender-dependent exception. Female Wixen plus male Katress produces Wixen Noct, while male Wixen plus female Katress produces Katress Ignis, so the calculator shows both outcomes instead of pretending there is only one result.
What are reverse parent pairs?
Reverse parent pairs are other combinations in the current breeding data that also produce the same child. They are useful when you already know the target Pal and want alternative routes instead of only checking one pair at a time.
Why does this page not estimate passive inheritance odds or hatch time?
This version stays aligned to data that is directly supported by the checked breeding tables and calculator logic: parent pair outcome, special overrides, breeding power targeting, and reverse combinations. It does not invent passive roll percentages, incubation timing, or environment multipliers that were not supported by the sources used here.
Can future Palworld updates change the result?
Yes. If the game updates breeding powers, special combinations, or exception handling, the same parent pair may need a different answer. Treat the page as a planning tool tied to the data revision listed in the sources and recheck after major patches.
