How this Pokémon Champions damage calc works

This tool implements the full mainline damage formula used by Pokémon Champions ranked battles: base damage from level, move power and the Attack/Defense matchup, then the modifier chain — spread, weather, critical hits, the 85–100% damage roll, STAB, type effectiveness, burn, screens, items and abilities — with the same rounding behaviour as the games. Results show all 16 damage rolls, the percentage of the defender's HP, and the exact chance to OHKO or 2HKO.

FAQ

Does this calculator work for Pokémon Champions ranked doubles?
Yes. Level defaults to 50 and the spread-move reduction (×0.75) and doubles screen modifier are built in — the same conditions as ranked battles.
Are all Pokémon and forms included?
The full National Pokédex plus battle forms (Therian formes, Origin formes, paradox Pokémon and more) — 1,200+ entries with official base stats.
How accurate are the OHKO / 2HKO percentages?
The calculator evaluates every one of the 16 possible damage rolls exactly as the game does, so KO chances are exact, not estimates.
Do I need to download anything?
No. Everything runs locally in your browser — no account, no ads walls, and it keeps working offline once loaded.
