GROM
EpicWho is GROM
GROM is a Epic-rarity brawler. This article summarizes their current competitive performance: best map, toughest counters, and weekly win-rate trend, all computed over real top-PRO battles in the last 14 days.
Over a 14-day window, GROM has appeared in 2,888 battles with a global win rate of 72.7% and a pick rate of 0.5%. That pick rate is the fraction of matches in which some top-PRO player chose GROM out of all available brawlers, so it works as a thermometer for how meta they are right now.
GROM is an Epic brawler, a rarity where kits start to break conventions: unique mechanics, supers with special effects and gadgets that flip the whole game plan. The gem or Star Drop investment is steeper, but in return you get a tool that defines entire lanes in draft and tends to be picked in tournaments whenever its signature map enters rotation.

The best map for GROM is Healthy Middle Ground in Knockout, with a Bayesian-smoothed win rate of 80.3%. That puts them above their class average in this mode, so it's worth picking GROM when that rotation is live. A strong showing on Healthy Middle Ground usually combines favorable geometry (short ranges or cover) and a mode whose objective fits the brawler's kit.
As the second-best option, GROM also performs well on Goldarm Gulch (Knockout) with a 78.3% win rate. The gap from the top map is usually small; choosing one over the other depends more on the enemy team than on the brawler.
On the opposite end, Hyacinth House (Hot Zone) drops GROM's win rate to 38.5%. If that rotation comes up in a session, consider another brawler to avoid throwing matches; the gap between best and worst map can be several percentage points.
Counters and matchups
GROM loses systematically to DYNAMIKE: across the 151 battles recorded for that matchup, their win rate drops to 79.6%. If you see DYNAMIKE on the enemy team during draft, consider not picking GROM or adjusting the game plan to avoid sharing a lane.
In the opposite matchup, GROM struggles against BO too: across 52 battles, GROM's win rate stays low, around 51.2%, indicating that BO deals heavy damage. These matchups often decide games as soon as the two brawlers share a lane.
Per-brawler matchups are the smallest-sample metric on this page, so read them with the sample-size badge in mind. A bad matchup with 50 battles tells you less than a map with 500.
Star Powers, gadgets and hypercharge
To get the most out of GROM in the current meta, prioritize upgrades by synergy with their kit, not by gem cost. Star powers, gadgets and hypercharge change tiers depending on the meta, so the upgrade priority is dynamic.
As a general rule, the first profitable upgrade for GROM is usually the star power with the highest pick rate in PRO tournaments, followed by the gadget that best fits their role (lane, support, or pick). Hypercharge, when it exists, comes last because it costs more Coins and Power Points and only triggers with a full super bar.
Beyond the immediate meta, the upgrade path for GROM should prioritize what moves the win rate needle the most: power 11 before gears, first star power before second, primary gadget before any hypercharge. Hypercharges cost a lot of coins and power points and only activate with a full super bar, so their real priority drops toward the end of the checklist.
Weekly meta analysis
In the last 7 days, GROM's win rate has held essentially flat compared to the previous 7. A swing under 1 percentage point we treat as stable because it fits within the natural sampling noise, so the meta hasn't shifted meaningfully for this brawler.
The 7-day trend is precomputed every six hours in a small Postgres table and computed with filter source=global. Full technical details live on the methodology page.
Every percentage on the GROM page comes from sampling top PRO battles with source=global filtering and Bayesian smoothing, recomputed every six hours. If you want to understand why one map performs better than another or how a rotation affects the win rate, the methodology page covers the technical detail step by step.
