Warning: This article contains spoilers for Cobra Kai season 4.

Is there anything more exciting in the wide world of sports than the phrase "sudden-death overtime"? Actually, yes: The phrase "shirtless sudden-death overtime."

This season on Cobra Kai, it all comes down to the All Valley Karate Championship. Rivals-turned-allies Daniel LaRusso (Ralph Macchio) and Johnny Lawrence (William Zabka) must defeat the malevolent Cobra Kai dojo — run by John Kreese (Martin Kove) and Terry Silver (Thomas Ian Griffith) — or they'll be forced to shut their own dojos down.
