Widowmeiker

Widowmeiker is the femslash ship between Widowmaker and Mei from the Overwatch fandom.

Canon
Amélie Guillard was a successful ballerina, and married a man named Gerard Lacroix, an agent for Overwatch. Talon, a terrorists organization, captured Amelie and tortured her util she became a sleeper agent. Overwatch rescued her, but two weeks after her return, she killed her husband and returned to Talon. They reconditioned her, turning her into an emotionless killer and lowered her heart rate, her skin becoming blue as a result. She took on the name Widowmaker, and became Talon’s most elite assassin.

Mei was an eco-scientist for Overwatch. She was studying at Eco-point Antartica, when she and her team had to go into cryosleep after a loss of power and lowering of supplies, hoping that someone would come to rescue them. Mei woke up eight years later, and was the only one to survive. She created a freeze gun that she used to help her leave.

The two have never been shown to interact in established Overwatch lore. They would be considered enemies, since Widowmaker works for Talon, and Mei for Overwatch.

Game-Play
Mei and Widowmaker can be used in the game, similarly to Hanzo and Mei. Mei can release her ultimate, freezing multiple players. Widowmaker can then easily make multiple head shots. On a smaller scale, when Mei freezes players with her cold gun, Widowmaker can also take them out the same way as the ultimate.

Fanon
The ship is more of a rare pair. This is due to both having more popular pairings. They also don't have any in game dialogue or lore for fans to draw from.

On AO3, there are currently only 9+ written works. While FanFiction.Net has less than 10 works written for the ship.
