Somnibot is a lullaby-singing, sleep-inducing monster whose powers were to put human and machine into a deep, peaceful sleep with her beautiful singing voice. In Rock-a-Bye, Alpha 5, she is built by Klank and Orbus and tasked with infiltrating the Power Chamber and singing Alpha 5 to sleep so he can get some much-deserved rest. However, she falls in love with the young robot and regrets her actions when Alpha's body temperature drops drastically. She keeps watch over the sleeping automaton and soothes him back to sleep when he has a nightmare. Rather than destroy her as they did in the Prime Reality, the Rangers decide that Somni should join their side, believing that perhaps the Royal House of Gadgetry will one day do the same.
