Best Grom Build
Most picked build across all modes
Best star power for Grom
Foot Patrol is Grom's most-picked star power at 50.0%. A star power is passive: once it is equipped it works on its own all match, with no button to press. X-Factor is the alternative at 50.0%.
Best gadget for Grom
The most common gadget is Watchtower at 57.0%. You fire it yourself and can keep using it all match, waiting out the cooldown each time, so players pick the effect they want on hand most often. Radio Check sees the rest of the picks at 43.0%.
Best gears for Grom
SHIELD leads the gear slot at 40.3%, with DAMAGE (24.8%) close behind. Gears add a smaller boost rather than a new effect, so this pick fine-tunes the build more than it redefines it.
What Grom players unlock
Of the Grom players who have unlocked only one star power, 61.4% chose X-Factor.
93.5% of maxed Grom owners have unlocked his Hypercharge.
What players who own Grom have unlocked, counted from tracked profiles over the last 30 days. "Unlocked first" is the share among the players who own only one of a pair, which is the closest thing to a preference the game data exposes: Supercell never publishes which build a player equipped in a match, so nothing here is a pick rate or a win rate by build.
