Gear names are the official API’s; the share is ownership among the sampled top profiles, never a match loadout.

• Gadget Buffie0.0%

• Hypercharge Buffie0.0%

A Buffie is an extra boost the wiki lists for an ability; the share is how many sampled top profiles own it, not how often it is used.

Coins and Power Points to reach Power 11, then the Gadget, Star Power and Hypercharge unlocks. Gear prices and the planner are on the upgrades page.

Rarity and class come from the wiki infobox; the order is alphabetical, not a tier.

Map fit by win rate is Being measured (gate G-M); the tiles above are ordered by the battles counted on them.

A rate is printed only when the tally is signed off (gate G-M). The rows above are counts of decided games in the trophy sample, 49,601 players read.

The export drew a loadout-by-enemy grid. Nobody measures a match’s loadout, so those cells would be invented; this table keeps the counts and names the gate.

A pair is listed at 75+ counted games on the same team. The pair’s edge over its two solo rates is Being measured (gate G-M).

No trio above the floor includes this brawler yet.

A trio is the three brawlers a team ran together on one map, counted from both sides. Its win rate waits on gate G-M.

Win rate before and after a patch Being measured — a replay needs the same brawler counted on both sides of the change at the sample’s floor, and the cache’s pre-patch side is too thin to reach it.

Creator builds for Grom are opinion. This page prints them nowhere: every figure above is either the wiki’s fact, the API’s list or a counted game total, and a creator’s recommendation has no cohort, window or sample to stand on.

GamGem editorial — not measured. When gate G-M closes, the counts above will carry their win and pick rates, and an opinion can then be compared with them rather than replace them.

Pick a question. Every answer restates a field above with its source; none adds a fact the sources do not state.

Dates belong to the fact: a wiki revision day, an API fetch day or the day a battle was played. A build day is never printed as any of them.
