The Overwatch hero who can use the Biotic Grenade ability is Ana. The ability is one of Ana Amari’s signature tools and reflects her unusual role as a long-range support sniper.
Ana throws the Biotic Grenade as a projectile that bursts on contact. The explosion heals allied heroes caught in its area and damages enemies. It also boosts healing received by allies while temporarily preventing enemies from being healed by outside sources. That combination makes it useful both defensively, when saving teammates, and offensively, when disrupting an enemy’s recovery.
Ana’s other core abilities complement the grenade. Her Biotic Rifle heals allies and damages enemies, Sleep Dart can disable a target, and Nano Boost strengthens a selected ally by increasing their combat effectiveness and survivability. Together, these abilities reward careful aim and good timing rather than constant close-range healing.
A common mix-up is choosing Moira or Baptiste because both are support heroes with biological or area-based healing tools. However, Biotic Grenade is specifically associated with Ana. Baptiste uses a similar-sounding Regenerative Burst, while Moira uses Biotic Grasp and Biotic Orb.
