Team Fortress 2, released by Valve in 2007, turned the Demoman into a popular melee subclass known as the Demoknight, armed with swords like the Eyelander and a shield for charging. His Highlander inspired lines, including the 'there can be only one' reference, became favourites in frag videos and soundboards. Players clipped the swing for Demoknight gameplay, loadout showcases and meme edits, and the short, loud delivery helped it spread beyond TF2 into general gaming videos where a barbarian charge needs instant recognition.
