"Details" opens Mega Aggron's per-move damage against that boss, its breakpoints and its energy cycle — the same drawer the boss page opens.

Mega Aggron places nowhere with Shadow, Mega and Legendary attackers hidden, so the table above is the everything-on ranking. With everything switched on it places on 5 bosses (best #12 vs Diancie). Points follow pokebattler.com's published rule — 5 for a first place, 4 for a second, 3 for a fourth, 2 for an eighth, 1 for a sixteenth, weighted 10x at Tier 5 / Mega, 4x at Tier 3 and 0x at Tier 1. Level 40, 15/15/15, no weather, no friendship, no dodging. Snapshot generated 2026-10-04.

Caught CP range 1,636 - 1,714, or 2,045 - 2,143 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.

Every tile and chip is a link: it opens the Pokedex filtered to that type, so a weakness leads straight to the attackers that exploit it. Pokebattler lists only the weaknesses; the eleven types that do neither matter as much to a raider deciding what to bring, so all 18 are shown with the exact multiplier.

STAB marks moves that share a type with this form (x1.2 damage), and the DPS and DPE columns above already have that x1.2 in them — so a STAB move and a stronger-on-paper neutral move can be compared straight down the column, which is how the best-moveset cards rank them too. Power and Duration stay raw; hover a DPS or DPE figure to see the arithmetic. Att DPS and Def DPS are the two columns pokebattler.com prints in the same table, reproduced exactly: both are raw with no STAB, Def DPS is power / duration, and Att DPS is power / (duration + 2s), the gym move delay. They are there so this table can be diffed against theirs row by row — every row on the pages read on 2026-09-11 matches. Energy is gained on fast moves and spent on charged moves. Every move name opens its own page with the damage window and every other form that learns it — or browse all moves.

Turns are the one-based count the game and every reference site print: the Game Master ships a zero-based durationTurns, so its 1 is a 2-turn move. DPT and EPT are damage and energy per turn and DPE is damage per energy, both with this form's x1.2 STAB already in them where the row is flagged STAB, so the columns can be read straight down; Power and Energy stay raw. A stat change moves the target up or down the game's own ladder (0.50, 0.57, 0.67, 0.80, 1.00, 1.25, 1.50, 1.75, 2.00 for stages -4 to +4). Every Trainer Battle number is audited on the data-quality page.

Every field above is read from the committed snapshot, never typed by hand.

1 move restored from Pokebattler's dataset

Pokebattler lists Brick Break for this form and this Game Master snapshot no longer carries it — legacy and event-only moves are the usual reason. Each one keeps the list Pokebattler puts it in, so Elite TM moves stay behind the legacy toggle.
