The main focus of this season is the mysterious and deadly Night King with his eerie blue eyes and a threatening look on his face. He first appears in the vision of Bran Stark in season 4.

Game of Thrones recently gave Twitter users emoji to unlock a batch of posters showing its stars transformed into the white walkers with blue eyes and grey skin. HBO also allowed Snapchat users to turn themselves into White Walkers.

This has turned into a frenzy of Snapchat filters with hashtags and fans looking like White Walkers.
