Somnibot

Somnibot is a lullaby-singing monster whose sleep-inducing power was 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.

In her first form, she wears a large nightcap on her head and her voice is rather yawn-heavy, as if her singing puts her to sleep as well. She also makes various sleep- and bedtime-related puns in her first form as well, specifically during her battle with the Gold Ranger. In her second form, however, her puns become a little more dark and sinister. As explained, in her first form she is very narcoleptic.

After her initial defeat, she returns with a power amplifier where her face used to be, even the Gold Ranger is no match for it and her attitude is much nastier, her characteristic sleepiness entirely gone. Later when she grows huge, she is destroyed by the Zeo Ultrazord but not before arrogantly claiming herself to be invincible.

Somnibot was seen as an audience member in Prince Gasket's Machine Arena. It is unexplained how she got revived from the attack.

Powers and abilities
Somnibot was assembled with the gift of song. She has the ability to sing lullabies that put people and even robots into a deep, peaceful state of sleep, using a harmonic sound weapon of sorts. When she sings, her eyes glow (first red, then light violet, then a bright white after her upgrade) and as she sings her Ranger targets slowly enter their dream state. Her non-Ranger targets simply collapse and fall asleep. She also waves her arms as she sings her cradle songs, causing light violet-colored energy to appear on her hands that spreads out over her soon-to-be dreaming victims. However, it is unclear on whether it is her singing or staring into her eyes that causes her victims to be placed under her sleeping spell.

In her first form, she can also shoot pink energy spheres from her mouth.
