Zodiac Monsters

Monsters created by the Zodiac Emperors.

Monstele
Monstele was created when Sagittarius shot a special arrow into a stone monument in a graveyard. He resembled a large stone chesspiece, humanoid but blocky and featureless. Monstele, being made of stone, was invulnerable to most attacks, and can generate black chains from its arms to ensnare his foes. It could also create mausoleums. Sagittarius's inspiration was the lack of any funeral arrangements for the recently fallen Blue Ranger; Monstele would be enough of a monument for the entire team. It engaged the Rangers and the Hex Rider in Angel Grove Cemetery, capturing him as well as the Pink and Green Rangers and trapping them inside an airtight mausoleum.

The Red Ranger confronted it and fought, doing badly until Alpha was able to finish the Battlizer form he'd been working on. The new attacks shattered Monstele, but left his mausoleum standing. Fortunately Super ZeoZord V was able to destroy the building and free his teammates.

Nevernight
Nevernight was a monster created by Sagittarius. Her body was cloaked in a dark blue cape; the only part really visible was her cyan eyes. She wielded a golden staff topped with an orb full of glowing numbers. With her staff Nevernight could control the dimension Aquarius gave to her. She used it to teleport from room to room and stop time. She could also manipulate her cape like tentacles, and had powers connected to special moments of time like 11:11.

Nevernight kidnapped all of the Rangers on New Year's Eve, in what she called the gap between the new year and the old--the time it took the clock to strike 12. She confronted them individually--first David, who tried and failed to morph. She tried to drown him before leaving to taunt Lidian about being trapped there forever while the Zodiac Emperors took over Earth. He attacked but her time-stopping kept him from even landing a blow. Next she moved on to Sabrina and Casey, who had found each other already.

She fought Sabrina, again avoiding all of her attacks, while Casey talked. She pointed out that Nevernight's "between years" thing didn't really work. It was arbitrary and only worked for their particular time zone. Angry, she vanished, allowing the dimension to collapse.

Trivia

 * Monstele's name comes from the word stele, which is a Greek term for a stone marker or monument.
