Heihachi Mishima is the longtime patriarch of the Tekken fighting game series, a stern martial arts master known for his gruff voice and iron will. Short damage grunts like this one are a staple of fighting games, signalling that a character has been hit without breaking the flow of combat. Fans have clipped and shared these brief reactions for years, and they now circulate widely as soundboard and meme audio. The clip endures because it is instantly recognisable to Tekken players and funny even to viewers who have never played the games.
