Raiden first appeared in the original Mortal Kombat arcade game in 1992 as the thunder god protector of Earthrealm. His flying torpedo, also known as the Thunder Fly or Superman move, became one of his signature attacks in sequels and adaptations. Players have long joked about the garbled shout during the move, trying to hear English words in what is really a stylised battle cry. Clips of the attack still circulate in combo videos, edits and soundboards because the move is instantly recognisable to fighting game fans.
