Roadhog is one of the original tank heroes in Blizzard's hero shooter Overwatch, released in 2016. 'Welcome to the apocalypse' is one of his in-game voice lines, delivered in his signature low growl, and it fits a character who is a masked, hook-wielding Australian outlaw surviving a ruined world. Fans lifted the line out of the game and it now circulates on soundboards and in gaming edits, where creators use it as a dark, funny warning before a big moment or a disaster clip.
