Once I've finished tearing this world into pieces, I'll just use Goku's Instant Transmission technique to move onto other planets. That is my destiny! I am the universe's end!!!
~ Cell

Villains who aspire to bring about the end of the world or universe they are in. A Cataclysm often has vast amounts of power, and is similar to a Dark Lord. Sometimes it can be a dark god or god-like figure. Cataclysmic Villains may also be villains that previously caused massive destruction to a planet without completely destroying it.

In extreme cases, some Cataclysmic Villains can also become Reality-Butchers as they have successfully destroyed or ruined entire universes, dimensions or realities. They are the very worst of the Destroyers and Genocidals and usually have no redeeming qualities as a result.

Since destroying an entire world is one of the worst thing these characters can do, they can qualify as Pure Evil only if their Moral Agency is made clear and if they display no remorses for what they have done.
