Agumon is the dinosaur-like Digimon partner of Tai in Digimon Adventure, and Shinka is the Japanese word for evolution used when a Digimon transforms into a stronger form. This version comes from Digimon Adventure tri, the sequel series that brought the original DigiDestined back as teenagers and revisited their classic evolutions with updated animation and sound design. The clip has since circulated among Digimon fans and anime editors, who reuse the familiar jingle as shorthand for a power-up, a comeback or a dramatic change of form.
