Evil laughter

[3] They are used by supervillains in comic books and video games,[2] generally when some form of victory is attained, to indicate superiority over another, or to mock another character's earnestness.

Maniacal laughter may confirm a character's villainy, signaling gratification from performing acts of evil.

This was a rare case of a non-villain character using an evil laugh, and it was voiced by actor Frank Readick.

Other examples of evil laughter in film include the alien in Predator, the stepmother in Cinderella, Majin Buu Dragon Ball Z, and the Wicked Witch of the West in The Wizard of Oz.

An example of this is in Raiders of the Lost Ark, where Belloq's laugh fills the South American jungle as Indiana Jones escapes from the Hovitos.
