The Gruesome Grunts

The Gruesome Grunts are a group of monster criminals led by Versix to destroy the Ninja Steel Power Rangers on a special Halloween episode.

Trivia

 * They are the only monsters that didn't work for Galaxy Warriors or wanting to claim the Ninja Power Stars.
 * Using Versix's magic, they swap bodies with the Rangers so they could be destroyed at the Halloween Intergalatic Court in their place.
