The Scorpio was described by Tarrant as "a Wanderer class planet hopper, Mark II by the look of it - obsolete but functional". It belonged to Dorian until acquired by Avon and his crew. Its speed at acquisition was unstated but deemed to be extremely slow in comparison to the Liberator, but once fitted with the photonic drive it could achieve Time Distort 15, but in real time (i.e. - without going into a time distort dimension like Federation ships needed to). In essence, this made the ship faster than the Liberator had been. The ship was generally under the control of the Slave computer, designed and installed by Dorian. It was also fitted with a teleport facility, installed by Dorian but non-operational until it was completed by Avon with Orac's help. Like most ships of this type, only the main deck was pressurized in flight. (D: Rescue)
Scorpio was taken by Avon and his crew to Helotrix, Caspar, Bucol-2, Pharos, Domo, Mecron II, Virn, Zerok, Beta 5, Malodar, Betafarl and Gauda Prime. Because of the teleport, landings were rarely made, and the ship was only seen to touch down on Terminal, Xenon, Caspar, and Betafarl. A landing was also made on Beta 5. Final touchdown was on Gauda Prime, where the ship broke in two on crash-landing.
Scorpio suffered damage in Stardrive, where it grazed an asteroid when trying to enter the Altern system, holing the main drive chamber as a result, and in Animals when attacked by pursuit ships above Bucol-2, suffering damage to the main detectors and AntiGrav Gyros. Control of the ship was lost in Power, when Pella briefly hijacked it, and Headhunter, where all systems came under the influence of Muller's android.
Orbital altitudes were mentioned twice: in Traitor the ship took up position 40 miles above Helotrix, and initial orbit over Malodar was 10 miles up.
Prior to installation of Dr. Plaxton's photonic drive, the ship needed fuel crystals derived from selsium ore. Other fittings included an orbital booster, inertial guidance glycolene ballast channels, precision guidance subsystem, thrust computer, short burn boosters to aid lift-off with a full payload, and armament which Soolin described as insufficient to "tangle with Federation patrols". There was also a gun locker for six clip guns (Rescue), a medicapsule (Headhunter) and facilities for in-flight docking (Gold).
