The Omnitrix is the alien device worn by Ben Tennyson in Ben 10, and the recalibrated version appeared in Ben 10: Alien Force, which began in 2008. After the original device was reset, it gave Ben access to a new set of alien forms, and its updated activation sound became closely tied to that era of the show. Clips of the sound later circulated in fan edits, transformation compilations, and soundboard collections, where its short, recognisable chime made it easy to reuse for reveals and power-ups.
