McSombra

McSombra is the het ship between Cassidy and Sombra from the Overwatch fandom.

Canon
Cassidy was one of the founding members of the Deadlock games, before he was arrested by Overwatch. Reaper gave Cassidy the option of joining or being thrown in prison. Cassidy chose to join and became a member of the Blackwatch team. When Overwatch disbanded, Cassidy became a bounty hunter.

Olivia was an expert hacker who was eventually picked up by the Los Muertos gang, where she stumbled upon a "Global Conspiracy". She investigated this until she was discovered, and in a panic, erased any trace of her existence. She eventually resurfaced under the alias "Sombra". Talon took note of her skills and recruited her, while she continues to search for answers.

It appears that the two know of each other or have met before based on Sombra and Cassidy's pregame interaction and the Reflections comic, in which they're drinking at the same bar.
