|Also called:||Marinus (possible)|
|Natives:||Cybermen, Mondasians, Lizard Kings, Mondasian Sea Devils|
Mondas was identical to Earth, even down to the size and shapes of its continents. When it approached the Earth in 1986, the planet was oriented such that its continents were upside down relative to Earth. However, it had no visible clouds in its atmosphere at that time. (TV: The Tenth Planet)
Native life Edit
Originally, the Mondasians resembled the humans of Earth in every respect. (TV: The Tenth Planet) One account shows that in the same way that parallels to humans existed on Mondas, Lizard Kings and Sea Devils shared the planet with dinosaurs and Cybermen. (COMIC: The Cybermen: The Dead Heart) Golgoth, a bipedal reptilian god in physical form, possibly linked to the Silurians, also lived on Mondas at this time. (COMIC: The Cybermen)
Mondas was created by the Constructors of Destiny as an experiment of sorts to see how it would differ from Earth. (PROSE: The Quantum Archangel) Mondas had, like Earth, at one time, an intelligent reptile species. (COMIC: The Cybermen)
Origins of the Cybermen Edit
- This implies a high degree of parallel evolution and/or contact between the two worlds.
During a time when parts of Mondas had a tropical climate, Cybermen met and warred with Silurians and Sea Devils. (COMIC: The Cybermen: The Dead Heart) Golgoth appeared and destroyed all but one Cyberman and finally destroyed the lone survivor. (COMIC: The Cybermen: ?)
Some centuries after, human-appearing Mondasians of roughly 20th century technological development had appeared and Mondas had begun to move out of its orbit. Archaeologists had discovered remnants of the Cybermen. (COMIC: The Cybermen: The Ugly Underneath)
- This last account implied that the discovery of the extinct Cybermen would lead to the Mondasians deciding to use Cybertechnology, beginning the cycle of creation anew and creating a new race of Cybermen.
Evolution of the Cybermen Edit
Mondas left that orbit and drifted on a journey to "the edge of space", (TV: The Tenth Planet), caused by the sudden arrival of a moon between Earth and Mondas. This upset the gravitational equilibrium of Mondas, causing it to escape it's orbit. Further away from the life-giving warmth of Sol, conditions on the planet grew steadily worse. This forced the inhabitants to relocate underground in order to survive. They had by this time developed a society parallel to that of 1950s England. The Cybermen took over and enforced cyber-conversion for the surviving Mondasians. (AUDIO: Spare Parts). One Cybermen faction, the Mondans, decided to stay on their homeworld. Another group, the the Faction, more committed to total cybernetic conversaion, pushed outwards in the solar system and colonised Planet 14. (PROSE: Iceberg)
The Mondans developed a drive which used electro-magnetic energy to push the whole planet through space. (PROSE: Iceberg) By some accounts, this drive was developed during the journey to "the edge of space" in order to effect a controlled return to their original orbit. (REF: Doctor Who: Cybermen) Other accounts suggest that the drive was developed by the Mondasians prior to total conversion, in order to avoid a hazard on the planet's course. (AUDIO: Spare Parts) Others suggest that the drive unit was created prior to the planet's departure from its original orbit, and was the ultimate cause of the departure.
Such a drive might have been intended to move the planet out of the path of an impending collision in its original orbit. (REF: A History of the Universe) The Doctor claimed not to know why the drive was developed, but his tone implied, obliquely, that leaving their orbit was a deliberate, if ill-advised, decision by the Mondasians. (TV: Attack of the Cybermen)
Return of Mondas Edit
In December 1986, the Cybermen invaded Antarctica while Mondas drew closer, draining Earth's energy to replace and supplement its own. However, the energy absorbed was too much, and Mondas disintegrated. The destruction of Mondas destroyed all of the Cybermen on Mondas and also killed all of the Cybermen on Earth, who were dependent upon Mondas for energy. As the planet plundered Earth's energy, the First Doctor's life-force was caught up in the maelstrom, triggering his regeneration into his second incarnation. (TV: The Tenth Planet)
Behind the scenes Edit
Origins of the concept Edit
The idea of a parallel Earth opposite in orbit to Earth itself has occurred in a lot of science fiction, though modern astronomers consider this unfeasible due to the orbital mechanics involved. The idea had earlier almost appeared in Doctor Who in the proposed Malcolm Hulke story The Hidden Planet. Apart from this, the idea occurs in countless comics, movies, novels and short stories.
Continuity conflicts and ambiguities Edit
Origin of the Cybermen Edit
The Cybermen origin story in The World Shapers portrays Marinus, Mondas, and the mysterious Planet 14 referenced in The Invasion as the same place. Lance Parkin in the un-official work AHistory has rationalised this away by speculating that Cybermen may have originated independently on different planets at different times. At any rate, other stories set in the Doctor Who universe don't take The World Shapers into account.
Origin of Mondas itself Edit
State of Change, which has an artificially created duplicate of Earth called Terra Nova, may possibly hint that Mondas once went by that name, but The Quantum Archangel explains the matter away unambiguously by saying that the Constructors of Destiny had created two duplicate planets as an experiment.
Other matters Edit
The date of Mondas' departure from its original orbit is not known, nor is the full extent of its wanderings through space. It is widely believed (and Spare Parts concurs) that Mondas' journey "to the edge of space" involved it physically leaving the Solar system and travelling through the galaxy. However as it apparently did not possess a propulsion system at the time, it is unknown how the planet could have attained sufficient velocity to cover interstellar distances in a period apparently of only a few thousand years.
It is interesting to note, whether this was intended or accidental, that Mondas is an anagram of "nomads", which is basically what the Cybermen are.
