The Blue Eyes White Dragon first appeared in Kazuki Takahashi's Yu-Gi-Oh manga in the 1990s and became famous through the anime series that followed in 2000. As Seto Kaiba's signature monster, its roar accompanied some of the show's most memorable summons and duels. Clips of that cry later spread across YouTube, forums and soundboards as duelists and editors reused it outside the series. It remains popular because the monster itself is instantly recognisable to anime fans, and the roar signals a legendary summon without needing any dialogue or explanation at all.
