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 Beldum.
Estimator is how many trainers of this strength the fight needs. Power is the share of Beldum'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.

Caught CP range 513 - 558, or 642 - 697 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.

Boss stats
How the numbers in the header are built.
| Header number | Worked out | Value | Inputs from |
|---|---|---|---|
| Attack | floor((96 + 15) x 0.5974) | 66 | Game Master base Attack, tier CPM |
| Defense | floor((132 + 15) x 0.5974) | 87 | Game Master base Defense, tier CPM |
| HP | 600 — fixed by tier, base Stamina 120 unused | 600 | tier HP pool |
| Lobby CP | floor((96 + 15) x sqrt(132 + 15) x sqrt(600) / 10) — no CPM term | 3,296 | Game Master base stats, tier HP pool |
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.
Beldum's own Pokemon page has its full movepool, evolution family, stat ranks and what it is good against as an attacker.
