Wraith King is Ostarion, a playable hero in Valve's Dota 2 who was originally known as Skeleton King before a rework in December 2013 renamed and remodeled him for the Wraith Night event. His undead monarch persona, wraithfire abilities and ability to reincarnate after death made his voice lines popular with players. Clips of his booming delivery circulated through gameplay videos, streams and soundboards, where the short excerpt became a standalone reaction for resurrections, villain entrances and mock royal announcements outside the game itself.
