In 'The Fifth Element', what is the name of the evil force that threatens the universe?

In 'The Fifth Element', the evil force that threatens the universe is called the Great Evil. It appears as a gigantic living fireball that periodically emerges from deep space and moves toward Earth.

The film establishes that the Great Evil returns every 5,000 years. The only defense is a weapon made from the four classical elements—earth, air, fire, and water—combined with Leeloo, the Fifth Element. The Mondoshawans protect this weapon and try to return it to an ancient temple before the threat arrives.

Jean-Baptiste Emanuel Zorg works for the Great Evil, although the force itself is not portrayed as a human or conventional villain. Zorg is an ambitious industrialist who believes cooperating with it will preserve his own power. The Mangalores are hired to obtain the elemental stones, but their involvement is secondary to the cosmic threat.

A common mix-up is answering “Zorg” or “Leeloo.” Zorg is the human antagonist, while Leeloo is the Fifth Element and the key to defeating the Great Evil. The film’s ending shows Leeloo combining the elements’ power to destroy it.
