Cosmo
Cosmo stats from millions of recent Brawl Stars matches: counters, matchups, best teammates, and win rates by game mode.
Cosmo is the lead astronomer at Starr Park's Observatory. Besides teaching visitors about the universe, he is constantly gazing at the stars searching for something...
Matchups
Strong Against
Struggles Against
Ranked by how much better or worse Cosmo does against each brawler than both brawlers' win rates in each game mode 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 Cosmo'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 Cosmo does teamed with each brawler than both brawlers' win rates in each game mode 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 Cosmo'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.

How many Cosmo owners have unlocked each ability. This is what players own, not what they equip: Brawl Stars does not report loadouts per match, so nobody can measure a win rate for a gadget or star power. "First" is the share of players who own only one of the two: the one they unlocked first.

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.
