Mercy is a character developed by Blizzard Entertainment for their Overwatch franchise. She was introduced at launch in their 2016 first-person hero shooter video game of the same name and again appeared in its 2022 sequel, Overwatch 2. Mercy has also featured in its related animated and literary media. Lucie Pohl voices Mercy in English-language Overwatch media.
Within the Overwatch narrative, "Mercy" is the callsign of Swiss doctor Angela Ziegler, who provided key medical support for the original Overwatch group. In-game, she is a Support class character who can heal and buff teammates and resurrect fallen teammates.
The character is one of the more popular in the game, being noted by Blizzard to be the most played support character during the game's beta. However, her resurrect ability has been criticized in competitive and professional play levels, given the swing in momentum the ability creates. Her gameplay mechanics have undergone various reworks and patches in an attempt by Blizzard to make her a more well-rounded playable hero.
