Shadow World

The Shadow World, which appeared in Power Rangers Lightspeed Rescue is a dark, desert-like world where all the villains the Power Rangers of the past, present and future destroyed, end up. It is something like Hell of the real world, or like the Netherealm of the Mortal Kombat game series. In a climactic battle between Queen Bansheera and the Lightspeed Rangers, the spirit of her second-in-command Diabolico cut the rope that she was using to escape the Shadow World's portal, and Bansheera fell in. Then the portal sealed up permanently.

The status of the Shadow World being the only afterlife for Power Rangers monsters is unknown, as in Ninja Storm, the Abyss of Evil is given the same status. It's unknown if they're somehow one and the same or if they're two seperate places.

In the end of Lightspeed Resuce when we are given a glimpse of the Shadow World, we see a monster who is wearing Rita Repulsa's signature outfit. This leads fans to believe that the evil parts of all of the villains who were purified by Zordon's lifeforce in Countdown to Destruction were sent to the Shadow World.
