Cobra Kai is the martial-arts drama sequel to The Karate Kid films, premiering in 2018 and following the renewed rivalry between Johnny Lawrence and Daniel LaRusso. Set around rival dojos and the All Valley Karate Tournament, the series revived its 1980s characters for a new audience on streaming, where short, punchy clips travelled easily into fan edits, reaction videos and workout montages. Its confident tone and instantly recognisable branding help explain why a brief intro cue still works as shorthand for competition, training and a comeback.
