Jet Jaguar

Jet Jaguar is a human-size robot created by Goro Ibuki. Known as the Electronic Robot, it is operated via remote control with a special radio wave transmitter. Programmed to never harm a human being, it has a circuit of conscience installed as a safeguard. After Jet Jaguar briefly falls under the control of the Seatopians, endangering humanity, the circuit is activated and the robot grows to enormous size. Jet Jaguar then teams up with Godzilla to defeat Megalon and Gigan.
