Prisoner #1524, Mad Scientist Genbu (狂気の科学者・ゲンブ Kyōki no Kagakusha Genbu?, 25-26): Arrested for endangering people in his time/space experiments. Being turtle-like, he had an obsession for turtles. Released by Don Dolnero, he was paid 50 million to eliminate the Timerangers. He managed to trap the Time Rangers in the Genbu Zone, composed of various pocket dimensions of his own making based on his research, sicking his Copy Timeranger (コピータイムレンジャー Kopī Taimurenjā?), copies of the Timerangers at their zenit, on them. Only Time Red and TimePink escaped the dimension, later managing to use a "in-sync battleplan" to destroy the Genbu Zone and the Timerangers' copies from the inside out without harming their friends in the process. Enraged, Genbu enlarged, created a Copy TimeRobo Alpha (コピータイムロボα（アルファ） Kopī Taimurobo Arufa?) to fight for him. Once the copy was destroyed, Genbu was brought in by Shadow Beta.
