Kamen Rider Ex-Aid aired in Japan from 2016 to 2017 as a video game themed entry in the long running Kamen Rider tokusatsu franchise. Its hero transforms using Gashats, small game cartridges inserted into the Gamer Driver belt, and the toys and belt simulators that followed made each insertion sound highly collectible among fans. Clips recorded from those simulators spread through soundboards and fan videos, and the short activation chime remains a shorthand for starting a transformation or powering up.
