According to Blizzard Customer Support: Mercy is Taken

If you've been planning on dry cleaning your fedoras, you may want to hold off. Recently, a Reddit user posted his correspondence with Blizzard's customer service. They reached out to them to see if it was possible to marry Mercy, the pocket-healing master of Overwatch. Now, hopefully this was just a funny jape for the player, but the internet is dark and full of horrors. The good news (or bad depending on your point of view) is that customer support actually emailed the player back. And their response was something special.


Why did I expect any different?

That's right, Roadhog. The probably 600 pound, deformed, trash-shooting, porcine villain of Overwatch. I really hope this didn't give you any horrifying mental images. Unless that's your thing. In that case, have at it. Just please, do not email us any fan art.

Given, I doubt this is any kind of canon. An email from customer support is a bit far from an official announcement. So far, though, this is the only word we have on a possible relationship. It doesn't quite make sense for the world's lore, though. And- no, wait. I'm not talking about this seriously. I refuse to. At least, not publicly.
