Black Flash comes from Gege Akutami's Jujutsu Kaisen manga and anime, where it is described as a distortion in space created when cursed energy is applied within a fraction of a second of a physical blow. Sorcerers like Yuji Itadori and Yuta Okkotsu have used it in major fights, which helped the move become one of the series most quoted power ups. Fan edits isolating the impact sound spread on TikTok and YouTube, turning the crackle and boom into a reusable cue for any sudden surge in strength.

Black Flash edit sound effect from Jujutsu Kaisen, featuring the sharp distorted cursed energy hit creators use for anime edits and power up memes.
This is a fan edit built around the Black Flash impact from Jujutsu Kaisen, where cursed energy flashes black and red within a tiny window on a physical hit. The clip layers the crackling charge, deep bass boom and echoing distortion into a single punchy moment that feels far bigger than a normal punch. At around sixteen seconds it works like a mini build and payoff, letting an ordinary strike land as a devastating power spike. Viewers instantly read it as overwhelming force and a character suddenly surpassing their limit.
