Monster Zero

A spaceship full of Illegal time jumpers was vacationing through the time-space continum, when Hedorah  on his way to Earth colided with the ship, causing it to spin out of control. The time warp drive became damaged, and exploded soon after warping the crew to the Far flung Planet X. The ship crashed into the center of the largest city. All of the crew were deceased, but a cage near the engine containing 3 Dorats were discovered by the Xians, and were experimented on. They were turned into a 3 headed, Golden Dragon, and were used in a Ploy to destroy Earth. It was killed, but because it was not the real King Ghidorah ,(The real one was created when Dorats were combined by radiation), The actual King Ghidorah lived on until dying of Radiation Overload (Much like Godzilla II), But the Xiens kept a DNA sample, and later made Monster 0 from it.
