Base stats and CP
Straight from the Game Master; CP uses the level 1 to 51 CPM table. Ranks are recomputed over the released forms in the snapshot on every render.
Stat product 1,101,600 — #1,011 of 1,123 released forms. Bars are scaled against the highest value in the snapshot, not a round number.
Evolution family

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.

Buddy, Pokedex and unlock numbers, all read from this form's own Game Master template.
Best against
Which raid bosses Yamper is a top counter for, aggregated over the 123 bosses on the roster the same way pokebattler.com aggregates its own attacker rankings.
Yamper does not reach the top 32 against any of the 123 bosses on the roster, with or without Shadow, Mega and Legendary attackers in the pool. That is an honest "no", not a missing measurement — it was ranked against every one of them.
As a raid boss (Tier 1)
Boss stats use 15/15/15 IVs, the tier CP multiplier and the tier's fixed HP pool.
Not in the current raid rotation snapshot. The counters below are still exact for the tier this form would be hosted at.

Caught CP range 410 - 450, or 512 - 562 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.
Type matchups
Every one of the 18 attacking types against this typing. GO multipliers: 1.6x super effective, 0.625x resisted, 0.390625x doubly resisted.
- Weak (1)
- Neutral (14)
- Resists (3)
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.
Released electric forms with the highest attack — they share every weakness and resistance above.
Movepool
2 fast and 2 charged moves, elite / legacy included. Ranked by damage per second (fast) and damage per energy (charged), both with this form's x1.2 STAB applied where it earns it.
17 x Spark per Thunder · 11.0s cycle · 202 power with STAB
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.
Trainer Battles
The same moves, on the Trainer Battle clock: 0.5s per turn, 100 energy cap, stat changes included. These numbers come from a separate Game Master template and are not the raid numbers above.
Fast 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.
