Superman Robot Y
One of the Superman Robots, it spots a "tiny transmitter, emitting a super-sonic signal, inside a hollowed-out book", which was brought into the Fortress of Solitude during a tour by a hoodlum. Superman Robot Y, at Superman's command, grabs the hood and and flies away with him to "turn him over to the law" (Act No. 261, Feb 1960: "Superman's Fortress of Solitude!").
