Pharmercy

Pharmercy is the femslash ship between Pharah and Mercy from the Overwatch fandom.

Canon
Mercy was part of the original Overwatch team alongside Pharah's mother Ana. A picture of the original Overwatch team shows a young Pharah with the team. Meaning that the two knew each other at the time.

Fanon
The ship name was created after many gamers were using the two as a combo move. Once Mercy's ultimate was accessed, she could fly up and heal or boost Pharah, who would then have more powerful attacks. Instead of refering to them as "Pharah and Mercy", gamers would call them "Pharmercy" as shorthand.
