Axos

Axos was a scavenger entity which came to Earth, supposedly for fuel. Its real motivations were to drain all energy from Earth to gain the secret of time travel. After its defeat, Axos returned to attack Earth twice.

Biology
Axos was composed of Axonite and the Axons. Gunfire could not hurt it. Axos was telepathic, linking the parts together, but all the elements of Axos could feel the pain of each other.



Axonite
Axonite was the miracle element the Axons traded with Mr. Chinn for the energy to re-fuel their ship. Axonite was a living substance. They claimed it could be used to enlarge and shrink organisms and to copy them. It was sent around the world to key points, where it would drain energy evenly. (DW: The Claws of Axos)

Axons
Though Axons had humanoid features, they were part of the main Axos structure. They looked like golden-skinned humanoids, but their true forms were large, tentacled creatures. They could use their tentacles to disintegrate enemies. (DW: The Claws of Axos)

Technology
The Axons described their technology as having taken a more organic route. They grew their ships from Axonite. The ships were covered in eyes, some embedded in walls, other on stalks. The Axons could communicate through them and the pupils lit up when they did so. The ship was also covered in claws which could restrain prisoners. The ship could fire long tubes to drag prisoners within. (DW: The Claws of Axos)

History
The Axos worlds were on the edge of the galaxy. They were crippled by extreme solar flare activity. Axos was the last remnant of their culture. They were scavengers, sucking energy from planets. Axos encountered the Master. They captured his TARDIS and kept him prisoner; he directed them to Earth, expecting to get back his craft.

In England
On Earth, they tried to start a 'feeding cycle'. They met with UNIT and promised them axonite to enlarge food and end world hunger. UNIT ordered worldwide distribution. The Third Doctor realised the Axons planned to drain the planet of all its energy. They took power from a nuclear power plant and later raided the plant, killing members of UNIT. They cloned Bill Filer for information but the real Bill escaped, preventing this. The Doctor stopped them by placing Axos in a time loop. (DW: The Claws of Axos) Some of the axonite was kept. The Forge had a sample of axonite. (BFA: Project: Lazarus)

In Japan
The Axons escaped the time loop and infiltrated 21st century Japan. Disguising themselves as humans, they produced a television programme for children promoting a new soft drink, Goruda. When children drank it, they developed telepathy and were transformed into Axons. Using the children as leverage, Axos convinced the mayor of Tokyo to send it power from a nearby nuclear plant, claiming they only needed enough power to leave. Instead, Axos used the energy to transform into a giant monster, aiming to begin a new feeding cycle.

The Eleventh Doctor defeated it by having the citizens of Tokyo turn on all of their electrical appliances, drawing the plant's energies away from Axos, starving and eventually killing it. (DWM: The Golden Ones)

The Doctor and Amy later discovered that Chiyoko had freed Axos from the time loop to ensure her own creation. (DWM: The Child of Time)

Beyond the 21st century
At an unknown time in the future, British explorers tried to break into the time loop Axos was imprisoned in. They wanted to use Axos' power to power the Earth. The mission went horribly wrong and the Sixth Doctor created a nuclear explosion inside the time loop and locked Axos in it. (BFA: The Feast of Axos)

Other appearances

 * In 2050, an Axon was imprisoned by the Department in the Dauntless Prison. It was set free by K9 Mark 2 and his friends. (K9TV: Liberation)
 * The Eighth Doctor said to Mary Shelley that in her future, she and the Doctor fought the Axons. (BFA: Mary's Story)

Behind the scenes

 * Axos had the second longest period before making a return. The Golden Ones was published thirty-nine years after The Claws of Axos. This follows the Macra with a forty year gap.
