The line comes from JoJo's Bizarre Adventure, the manga created by Hirohiko Araki in 1987 and later adapted into a long-running anime. Jotaro Kujo is the lead of the Stardust Crusaders arc, where Stands were introduced as manifested fighting spirits. Short Jotaro quotes circulate widely on soundboards alongside other JoJo staples such as Za Warudo and the To be Continued sting. Fans keep reusing this one because a single serious sentence can caption almost any reveal, pose or entrance as if it were a major battle moment.
