Mortal Kombat 9, released in 2011 and developed by NetherRealm Studios, rebooted the long-running fighting series while bringing back classic fighters like Raiden, the thunder god protector of Earthrealm introduced in the original 1992 arcade game. Short voice clips from its matches, including character defeat yells, were later ripped and shared on gaming soundboards and in video edits. Raiden's K.O. scream survived outside the game because it is instantly recognisable to fans and works even without context, making it a go-to shorthand for a dramatic fighting game loss.
