Seto Kaiba is the wealthy, arrogant rival at the centre of Yu-Gi-Oh, and his over-the-top confidence has made him a long-running favourite for dramatic meme edits. Clips titled Kaiba Insane Asylum circulate on soundboards as shorthand for a moment when that confidence tips into obsession, giving creators a ready-made reaction for duels, rivalries and exaggerated villain scenes. Because the character is so recognisable, the sound works even without context, and it keeps appearing in short videos, reaction edits and fan-made compilations that play up his most theatrical side.
