[3][4] Although a machine endowed with superhuman strength and futuristic weaponry, he often displayed human characteristics, such as laughter, sadness, and mockery, as well as singing and playing the guitar.

This was filmed either in close-up or behind something to obscure the actor's feet protruding out the bottom; this version of the suit was informally referred to by the cast and crew as "the Bermuda shorts".

The "hero" was privately owned by TV and film producer Kevin Burns, who commissioned a replica in the early 1990s for touring and conventions.

There it had different domes, different color scheme, and an added rectangular skirt of gold-colored tubes, covering the rubber bellows legs and base.

Vastly different from the original series, the special only retained the characters of Dr. Smith (voiced by Jonathan Harris) and the Robot, now called "Robon" and bearing a distinctly purple paint job.

This Robot was of a more humanoid appearance, though missing its arms and legs (which were presumably in storage), and had shining round blue eyes in an otherwise featureless face.

After integrating a new alien engine into the Resolute, the Robot turned on Will after saving the dying Scarecrow from being tortured, but after failing to try and hijack the ship to return to its home planet to repair Scarecrow, it helps the children hijack a Jupiter so they can return to the planet after Hastings, a high ranking member of the crew, tried to kill them.

The Robot stays behind to fight off Hastings and the guards so that Will and Ben Adler, a human they befriended, can return Scarecrow to their kind.
