Mercy is a supporting female hero in Overwatch who can engages one of two beams that connect to an ally. By maintaining the beams, she can either restore that ally’s health or increase the amount of damage they deal.
Mercy shoots a round from her sidearm. It's best reserved for emergency personal defense. In Overwatch, Mercy always flies towards a targeted ally, allowing her to reach them quickly and provide assistance in crucial moments. Propelled by her Valkyrie suit, Mercy slows the speed of her descent from great heights.
Mercy can also radiate restorative power, bringing nearby dead allies back into the fight with full health.
