Evolutions are form-accurate: a regional form evolves into its own regional form, and a branch the game does not have is not drawn (Alolan Raichu names Pikachu as its parent but is not what Pikachu evolves into, so no line is shown). Mega Evolution is not part of this family — it costs Mega Energy and reverts, so it sits with the forms above.

Its best showing is18againstHeatran(Tier 5) with Mud-Slap + Earth Power.

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

Ranked with Shadow, Mega and Legendary attackers hidden — pokebattler.com's own default, so a place here is comparable with a place on its counter page. With everything switched on it places on 0 bosses. 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.

Catch CP after the raid

• Double weak (1)
• Neutral (12)
• Resists (5)

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.

Same typing, same matchups

Released water / ground forms with the highest attack — they share every weakness and resistance above.

Fast moves

Charged moves

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.

Charged 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.
