Doctor Ray is one of the four main antagonists (alongside the Three Sages) of the Doraemon: Nobita's Sky Utopia. He was a doctor who once did research to manipulate people's minds in the 22nd century and the creator of his robotic puppets Three Sages.
History
Once presumed missing, he appears after Doraemon is turned into an insect. He wants to activate the device to manipulate people's minds, but Sonya thwarts his plan. Doctor Ray puts the Paradapia into freefall mode and escapes. Later, Marimba calls the Time patrols after everyone is evacuated and Doctor Ray is captured and arrested for his crimes.
