Kamen Rider Cronus debuted in the Japanese tokusatsu series Kamen Rider Ex-Aid, which aired from 2016 to 2017 as a video game themed entry in the long-running Kamen Rider franchise. Cronus was presented as an overpowered final form controlled through the Buggle Driver II, with a time-manipulation ability reflected in the clocks and pause motifs of his transformation sound. Clips of henshin sequences became widely shared among tokusatsu fans online, cut into edits, soundboards and reaction videos, and Cronus's longer, more menacing jingle remains a favourite for dramatic entrances.
