Synopsis by Hal Erickson
Future Hill Street Blues star Daniel J. Travanti (billed as "Dan Travanty") guests in this episode as Ilan, shaggy-haired leader of a band of space cyclists. Hoping to rise above their "misfit" status, Ilan and his fellow cycle bums agree to blow up a planet in order to keep it colliding with their own. Alas, the planet slated for destruction is currently occupied by the Robinsons--and the cyclists have no intention of letting them escape! The plot takes a bizarre twist when, thanks to a gaseous substance, Dr. Smith (Jonathan Harris) is suddenly transformed into a green-haired muscleman--whose awesome strength keeps failing him at the most inopportune moments!
