Kaioken is Goku's signature technique in Dragon Ball Z, multiplying his power, speed and energy for a short burst at great physical cost, with Kaioken x10 marking one of its most dramatic escalations during his battle against Frieza. Clips of the transformation became a shorthand for going all out in anime fandom, then spread through YouTube edits, gaming montages and TikTok, where the rising charge and scream are instantly recognisable even without the visuals. It endures because it compresses an entire comeback arc into under ten seconds.
