Kienzan is Krillin's signature technique in Dragon Ball, known to English-speaking fans as the Destructo Disc, a spinning disc of concentrated energy that can cut through almost anything. The attack became closely associated with Krillin despite being copied by other fighters in later stories, and its distinctive buzzing sound travelled from the anime into video games, fan edits and meme compilations. Creators still reach for it because it signals a clever, unexpected counterattack rather than brute force, giving a short clip an instant anime payoff.
