Somnibot

Somnibot (voiced by Barbara Goodson) is a female lullaby-singing, sleep-themed monster, created by Klank & Orbus on Mondo's suggestion, whose sleep-inducing power enabled her to put both human and machine into a deep sleep (the type of sleep that Snow White and Princess Aurora would fall into) by the power of her voice; in other words she uses a music- and brainwave-based hypnotic spell that both tires and weakens her victims, putting them into a deep sleep. She even attempted to place the Gold Ranger under the power of her lullaby and put him to sleep as well. She was first defeated in her battle with the Gold Ranger at a riverbank near Angel Grove. To protect themselves from being affected by the sleeping spell, Klank & Orbus both wear acoustic, spell-resistant headphones/earmuffs at one point.

Somnibot speaks and sings in a very cute, childlike and sweet-sounding voice.

In both of her forms, her primary method of attack is to induce sleep; an especially deep slumber that can be experienced by both humans and machines alike. She does this by singing a lullaby, while her eyes glow brightly like twinkling stars, intending to mesmerize, calm and lull her opponents. Her victims would then fall asleep and then possibly experience very sweet and peaceful dreams (albeit against their will), but she was destroyed by the Zeo Ultrazord before they could be seen.

When Zordon was briefing the Rangers on Somnibot, Rocky mused that her spell (and in effect, her singing and presence itself) sounded like a good idea right then, as the Rangers were sleepy from overwork at the time and needed some rest. She is also described by Zordon as "King Mondo's latest creation" when he is briefing the Rangers on her.

In her first form, she wears a large pink nightcap on her head and her voice is rather yawn-heavy on occasion, 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 at the riverbank. In her second form, however, her puns become a little more dark and sinister. As explained, in her first form she is very narcoleptic. Overall, she has a very adorable-looking appearance in her primary form, resembling a child's toy robot.

After her initial defeat, she returns with a giant, megaphone-shaped speaker where her face used to be. Even the Gold Ranger is no match for her powered-up sleeping spell and her attitude is much nastier, her characteristic sleepiness and sweet-looking nature entirely gone. Later when she grows huge, she is destroyed by the Zeo Ultrazord but not before arrogantly claiming herself to be invincible. Queen Machina later fretted over Somnibot's destruction, though her husband was asleep at the time.
