Simon Cardenas was a teenage time-traveler from San Francisco Island in the year 2062. After stealing his father's time-belt, he collided with a Myzarnian Cyborg while traveling through the time-space corridor, and his damaged belt drops him off in the Land of the Lost following a dimensional shift. Simon wore an "inter-trans" suit that apparently worked in conjunction with the belt, possibly protecting the wearer from the forces involved in such travel. Simon returned home once the belt's auto-recall device was activated.
