Janemba is the main villain of the 1995 Dragon Ball Z film Fusion Reborn, a demon created when evil energy possesses a young ogre in the afterlife. His distorted voice, strange movements and reality-warping powers made him stand out from more conventional Dragon Ball villains, and later appearances in Dragon Ball video games kept him familiar to new players. Short clips of his voice and presence are now reused online as a shorthand for a sudden, overpowered threat, especially in anime edits, gaming montages and reaction memes where a calm scene suddenly turns dangerous.
