Astran

Astrans were the dominant intelligent species of the planet Astra.

Biology
Astrans appeared as large egg-shaped translucent blobs, who got about on discs. They had no recognisable facial features, although they had the ability to speak. (COMIC: Space Border Battle) At least one Astran had the ability to shoot a painful and potentially deadly ray from an otherwise-invisible round "patch" on their "forehead". (COMIC: Colonel Zodiac Disappears)

Although some Astrans were light blue, (COMIC: Space Border Battle) others had purplish or greenish tinges to their blue membrane, (COMIC: Ceasefire — But War Tension Mounts...) and there existed at least one wholly green Astran and one wholly orange one: the Kaplan Minus and the Kaplan, respectively. (COMIC: Colonel Zodiac Disappears)

Culture
Astrans called the humans "Solarians", as they were the masters of the solar system. (COMIC: Space Border Battle, Colonel Zodiac Disappears, etc.) They were governed by a figure called the Kaplan, whose elevated status was marked by their personalised purple-and-gold hover-disc. Placed directly under the Kaplan was the Kaplan Minus. (COMIC: Colonel Zodiac Disappears) A prominent rank in an Astran space fleet was that of Kapt. (COMIC: Ceasefire — But War Tension Mounts..., President Offers Peace...)

Technology
The Astrans' technology and architecture largely reflected their physical appearance, containing a plethora of pastel-coloured spheres. (COMIC: Colonel Zodiac Disappears) This included their flying saucers, (COMIC: Space Border Battle) which were equipped with long range sonar scopes (COMIC: President Offers Peace...) and target-seeking rockets called Chasers. (COMIC: Colonel Zodiac Disappears)

Being blobs with a flat underside, the Astrans primarily used hovering personal, metallic discs to get about quickly, both aboard their ships (COMIC: Space Border Battle) and on Astra. (COMIC: Colonel Zodiac Disappears)

The Space War
By 2065, the Astrans had formed an Astran Empire which had initiated tense but generally peaceful diplomatic relations with the humans of the Solar System, whom they called "Solarians". However, early on 1 May 2065, an Astran space fleet patrolling the border between the two superpowers exchanged fire with the human Tenth Space Fleet over a misunderstanding, sparking a Space War. (COMIC: Space Border Battle)

Peace talks
Thanks to the cooperation of the Astran ambassador on Earth, the President of Earth wrote a message (COMIC: President Offers Peace...) which, after being carried to Astra at great personal risk by Colonel Zodiac, was read by the Kaplan and agreed to. The Kaplan agreed to come to Earth personally to sign a peace treaty. (COMIC: Colonel Zodiac Disappears)

Undated events
Two Astrans on hover-discs were among the tourists visiting the Skaro Observatory when the Fourteenth Doctor first stumbled there. (COMIC: Liberation of the Daleks)
