A Martian first appeared in Mr. Dingle, the Strong with a robot body and two alien heads including antennae. The second appearance was in the episode Will The Real Martian Please Stand Up?. In this one he was Mr. Ross (the human male who wanted to get to Boston) and he has a third arm coming out of his chest. He was an early scout from Mars sent to see if Earth is colonizable by the Martians. He did not go on the bus with the other passengers because he knew that the bridge was going to collapse. He realized that the Martians could not colonize Earth because the Venusians had arrived first.
