Somnibot

Somnibot is a lullaby-singing monster whose sleep-inducing power were able to put both human and machine into a deep peaceful sleep with her beautiful voice. She even attempted to hypnotize the Zeo Rangers at one point. She was first defeated in her battle with the Gold Ranger.

She then returned with a power amplifier where her face used to be, even the Gold Ranger was no match for it and her attitude was much nastier. Later when she grew huge, she was destroyed by the Zeo Ultrazord.

It is unknown if she was killed or purified by Zordon's Energy Wave, as she was last seen in Prince Gasket's arena in King for a Day.
