Ordered by Overall, pokebattler.com's own default — a blend of how fast the fight ends and how many of your six go down. Click any numeric column heading to re-order on that column alone.

Times are one trainer with six copies of that attacker, level 40 at 15/15/15, no weather, no friendship, no dodging, Shadow / Mega / Legendary attackers hidden — the same defaults pokebattler.com's own counter pages open with. Open the full counter tool to change any of them. "Details" opens the per-move damage, breakpoints and energy cycle against Corphish.

Estimator is how many trainers of this strength the fight needs. Power is the share of Corphish's HP that six of that attacker remove inside one raid timer, so over 100% means they finish it with time to spare. Faints is how many of the six go down inside that timer.

Hardest movesets to raid against

The boss rolls one of these 10 pairings, and it changes the fight. Each row re-runs the top 6 counters against that single moveset.

A raid boss rolls only its standard movepool — never a legacy or Elite TM move, verified against Pokebattler's own per-moveset list for six reference bosses. The ranked table above averages over all of these, which is what Pokebattler's DEFENSE_RANDOM_MC means.

Caught CP range 653 - 703, or 817 - 879 when the weather boosts it.

A raid encounter is level 20 (level 25 weather boosted) and cannot roll an IV below 10/10/10. Anything outside the first range is not this raid's reward.

A raid boss uses 15/15/15 IVs, its tier's CP multiplier and its tier's fixed HP pool — stamina does nothing, which is why the same species is a different fight at every tier. Every tier constant above (CPM 0.5974, 600 HP, 180s timer) is copied from Pokebattler's own published /raids tier table into src/engine/constants.ts, with the source named there.

Corphish's own Pokemon page has its full movepool, evolution family, stat ranks and what it is good against as an attacker.
