The Undertaker is the long-running WWE persona of Mark Calaway, who debuted the Deadman character in 1990 and became known for slow, theatrical entrances in darkened arenas. The tolling bell became his signature cue, signalling that he was about to appear, and clips of that entrance spread far beyond wrestling through television, video games and online edits. Because the bell is instantly recognisable even without any visuals, creators still reuse the full entrance music for dramatic reveals, boss entrances and Halloween content decades later.
