Game Of Thrones: 10 Most Shocking Moments From Season 5

Whenever these golden masked chaps from Slaver's Bay decided to pop up, fans knew a lot of people were about to die. Their first appearance was pretty shocking, but it's the impact they had later in the season that really cemented them as dangerous villains during the fifth season of the show.

By killing poor Ser Barristan Selmy and injuring the second best Game of Thrones character without genitalia (shout out to Varys) in Greyworm, the Sons of the Harpy became this really dangerous elephant in the room. Whenever you went to Slaver's Bay, you just knew there was a chance a golden mask might pop out and kill another fan favourite.

Depending on who their leader was, there could be a bit more of them next season.
