Ultraman Z premiered in 2020 as part of Tsuburaya Productions' long-running Ultraman tokusatsu franchise, following a young hero who bonds with the giant alien defender. Short clips of the character's exaggerated shouts and transformation energy were quickly clipped by fans for edits and soundboards. The drawn-out Rasegggssss cry stood out because it sounds both fierce and absurd out of context, making it easy to reuse far beyond anime and tokusatsu fandom. It now circulates as a quick shorthand for charging up, showing off or treating a small win like a world-saving event.
