In a recent Instagram post, Lucie Pohl (voice actor for Mercy on Overwatch) posted a selfie of herself near a recording microphone. However, hidden in one of the corners of the photo is this:
I know you can't see the full first word, but what else could it be? That says 'DUNGEON BOSS'. No denying it.

Favorite hero: Hansuke
Currently: Waiting for new PvE content and the PvP revamp.
