Nighloks

The Nighloks are vicious demonic beings that reside in the Netherworld and need to bathe in the Sanzu River's waters once in a while or else they dry up. Their goal is to flood the Sanzu River with the sorrows of humans and into the crevice from the Netherworld to the Earth.

## Moogers

   The Moogers are coral/sea anemone foot soldiers that serve Master Xandred. They are armed with swords and bows. There's also Giant Moogers that are used to fight the Zords. There were also Flying Moogers for aerial attacks which first appear in "Jayden's Challenge" to assist Robtish.

There are other Moogers equipped with blasters, but the even stronger ones are the Master Blasters which have professional hats and take many Moogers to carry starting with "Trust Me."

In "Party Monsters," the Moogers that were slain by the Rangers were shown in the Nighlok Heaven catering the Halloween party that the defeated Nighloks attended.

The Moogers made an appearance at the 2011 Macy's Thanksgiving Day Parade attempting to "kidnap" Al Roker only to be defeated by the Samurai Rangers.

## Spitfangs

The Spitfangs are secondary foot soldiers that resemble skull-like, eyeless, crocodile-heads with a killer whale-like body, and Nozuchi-like arms and legs. They can breathe fire quite readily. Like the Moogers, Spitfangs can be enlarged to fight the Zords. Each Spitfang comes in two different colors: gold and blue.

## Papyrox

The Papyrox are giant origami-based monsters created by Serrator, who carves out their shapes from a piece of paper. The Papyrox are considered to be stronger than the Moogers and the Spitfangs. Some versions of the Papyrox wield double-bladed swords.

## Nighlok Monsters

The Nighlok Monsters are Yōkai-like monsters used by the villains to attack the Human World. They are dependent on waters from the Sanzu River for survival, therefore needing the negative emotions of humans to keep it from drying out. They are trying to expand the Sanzu River to make it flood into the human world so the Nighlok can rule both worlds. All Nighloks have an ability to enter the living world through cracks and narrow gaps. When a Nighlok is destroyed once, it can grow into a giant Mega-Monster on its own that the Rangers need to use the Megazord to defeat. When a Nighlok is destroyed, it ends up in the Nighlok Heaven as seen in "Party Monsters."
