Grom
Grom stats from millions of recent Brawl Stars matches: counters, matchups, best teammates, and win rates by game mode.
Grom is a brawny security guard with one weak point: the flashbacks he gets from his time working at a kindergarten. Those kids were merciless.
Matchups
Strong Against
Struggles Against
Ranked by how much better or worse Grom does against each brawler than both brawlers' overall win rates predict. +5 means five percentage points more wins than expected, so the matchup itself is the reason, not one brawler simply being strong in this update.
Win Rate Against
Highest Win Rate
Lowest Win Rate
How often Grom's team wins when the other brawler is on the enemy team. This mostly follows how strong that brawler is right now: whoever is top tier in this update sits near the bottom of almost every brawler's list, whatever the matchup.
Teammates
Best Teammates
Worst Teammates
Ranked by how much better or worse Grom does teamed with each brawler than both brawlers' overall win rates predict. +5 means five percentage points more wins than expected, so the pairing itself is the reason, not one brawler simply being strong in this update.
Win Rate With
Highest Win Rate
Lowest Win Rate
How often Grom's team wins when the other brawler is on it too. This mostly follows how strong that brawler is right now: whoever is top tier in this update sits near the top of almost every brawler's list, whatever the pairing.

Ranked stats come from matches at Diamond 1 and above. They can differ from the regular stats above because ranked is a draft with bans. Teams take turns choosing, so they can counter the enemy team and pick brawlers that suit the map. In regular play you pick blind, with no idea what your opponents will bring.
