How it works
What you can do
- How hard does it hit? Every move, both ways, with KO chances
- Who wins one on one? The 1v1, turn by turn; pick each turn’s move
- What would flip the result? Tap a move: the fewest points (Stat Points or EVs) to survive it or KO faster
- How does it do against the meta? Meta table: the most used Pokémon, both ways, Speed (Champions and Scarlet & Violet)
- Survive, KO and outspeed at once? Fewest points (Stat Points, or EVs) finds the cheapest spread for all goals Advanced
- What about partners and spread moves? 2v2 board: every move into every target Advanced
- Do two hits KO together? Total damage: add a move’s hit from its Details Advanced
- Weather, screens or Tailwind? The Field bar; each card’s stages and status
- Got a set or team? Paste a set or team from Showdown or PokePaste
- Want to share it? Share: a link, Discord text or a Showdown set
Simple and Advanced
- Simple: the same numbers in plain words (“KO in 2 hits”), with fewer controls.
- Advanced: everything. Stat Point steps, crits, all 16 rolls, the formula, the 2v2 board, Total damage, Fewest Stat Points.
- The switch under the title; this browser remembers it.
Rules
- Champions (default): level 50, perfect IVs.
- Stat Points: +1 to a stat each, up to 32 per stat, 66 in all.
- Stat Alignment: one stat +10%, another −10% (like a nature).
- Mega Evolution: yes (hold the Mega Stone). Tera: no.
- Changed moves use Champions’ numbers.
- Scarlet & Violet: EVs, IVs, level and Tera Type. Every Pokémon, move and item.
- Pokémon Monomyth (the fan-made Emerald hack): its own Pokémon, forms and moves with its own numbers, EVs, IVs and level, no Tera.
- Gen 9 damage rules. New moves and abilities count for power, type and category only.
- Fetched when you pick it. No usage or teams.
Doubles
- Spread moves do 75% to each target (“Both foes ×0.75”). Pick “One target” when only one is left.
- The Field bar: weather, terrain, screens, Helping Hand, Tailwind, hazards, rooms, auras, Ruin.
Reading a result
- Damage roll: each hit does a random 85–100% of its top damage (16 values).
- The % range: lowest to highest roll, out of full HP.
- KO chance: every roll, against the HP it has now.
- The bar starts from the HP you set; its key says what each part means.
- Why this number: a move’s Details list every modifier. A move that does nothing says why (an immunity, Psychic Terrain blocking priority…).
- Damage formula: the steps from the stats to the damage, rounded as the games do.
- 1v1: the line under the matchup says who wins and why. Its Details has the turns.
- 1v1, end of each turn, in the games’ order: weather, Leftovers, poison, burn, Leech Seed, binds (Fire Spin, Whirlpool…), Salt Cure, Curse.
- 1v1 chances: misses, full paralysis, how long sleep lasts, confusion, Attract; crits once Count critical hits is on.
- What would change it: the fewest Stat Points for the target to take one more hit, or for the attacker to need one fewer.
- Advanced › View turns any block off.
Tools
- 2v2 board: both sides, every move into every target. Partner effects count (Helping Hand, Friend Guard, a second Intimidate).
- Total damage: add 2–4 hits for their exact KO chance.
- Meta table: your Pokémon vs today’s most used, both ways, and who’s faster.
- Fewest Stat Points: the fewest to survive a hit, KO a target and outspeed it.
Sets and your team
- In Champions, new picks start with their most used set: the in-game ladder’s, else Showdown’s (Customize › Usage numbers puts Showdown first). Monomyth has no usage: a new pick starts with its four strongest moves.
- The set menu has other common sets. The pickers show how many players choose each option.
- “+ Team” adds the set to your team; the strip loads any of your team.
- Paste a set or team from Showdown or PokePaste.
