Seventh Master

The Seventh Master is the renegade Time Lord, the Master, in his seventh on-screen incarnation.

Regeneration
The Master, now with a completely new body and therefore has a new cycle of regenerations. After his sixth incarnation is mortally wounded after escaping the Doctor using a Random Planetary Teleporter and landing in an unknown location on Earth, the Master regenerates but does for too long and gets younger and younger, until practically teenage (DW:Tree Of Life).

Initially outraged at the outcome of his regeneration, dryly stating: "Puberty all over again...fantastic!", he comes to realise that this could have its benefits, as he realised how important humans thought youth was.

The 'Face of Zythen'
As 'Archie Kapitan', he persuades the board of directors of the communications company, Zythen to use him to spearhead the company's 'Babylon' project, concerning their new range of telecommunication devices.

With his expertise in advanced technology, he used the signals in the radios and televisions when advertising to Britain. Also, he began to influence the manufacturers of communication devices in Naismith's top factories, implanting devices with small microchips he named 'Worms'. These chips sent out a frequency when activated that somehow focused on humans only and triggered a strange signal that slowly 'cancels out' the electrical impulses in the brain, rendering the human brain dead (DW: Vengeance Sevenfold).

Rise of Babylon
The Master, now secretly arming himself with weapons (even fashioning another laser screwdriver) with the funding and resources of the Zythen factories. He then successfully took over the entire company by killing the board of directors and using special 'Worms' that are physically inserted in the brain and telepathically linked to the Master himself to take over the workers and fashion his weapons.

He then launched a satellite that allowed him to seize and control all telecommunication devices (mobiles, computers, radios, televisions etc.), naming it 'Wormwood 5'.

Second Domination of Earth
He activated the satellite and proclaimed that he is holding 'humanity hostage'. He has become bitter and vengeful for his defeat on the Valiant, and wants to make sure that no one may challenge him or he sends the deadly signal to 'Wormwood 5' which would be amplified by the amount of online 'Worms' in Britain, using them as a transmitter to send the killer signal to every part of the Earth, killing everyone. His demands were simple, once again conquering the globe (DW: Tree Of Life).

His declaration of global rule occured exactly when the Doctor and Amy Pond landed on Earth and witnessed humanity's instant submission. The Doctor hacked into the Zythen headquarters (now the Master's base of operations) and spoke directly to the Master who relished in knowin that this time, the Doctor is powerless. The Doctor then asked the Master to stop while he can, as he doesn't have to use Earth as the new Time Lord Empire again (the Time Lords by this time, were already ressurected). The Master retorted by venomously stating that he knew that, but he wanted to show the Doctor just how much he wants his enemy to sink, by first destorying his beloved humans, but also giving the Doctor the oppurtunity to save them and 'cut him down to his level' once he fails.

He activated the signal, but made sure it was as slow as possible, giving the Doctor just less thaan 24 hours to stop him before humanity becomes extinct and Earth can become the Master's new kingdom (DW: Vengeance Sevenfold). Unfortunately, the Master's ego once again brought his down fall when the Doctor infiltrated the controls of 'Wormwood 5' when the Master is distracted by Amy's diversion. The Doctor focused the Master's signal on the Master's own brain and activated it, slowly killing him. The Doctor shown mercy (stating that was what made the Doctor better than the Master) and deactivated the signal and destroyed all the Master's arsenal. He then took the Master to New Gallifrey to await trial.

The Master disappeared sometime before the trial.

Personality
This Master is the youngest, so therefore the most unpredictible. He displays frequent and violent mood swings, coupled with his razor-sharp wit and dry humour.

His sadism and manipulative nature still remain. He uses his younger form to make himself underestimated and gain an advantage upon those who oppose him. His sadistic pleasure in misery and death is intensified with almost child-like enthusiasm. However, he almost always retains a dark, brooding and bitter persona (especially to the Doctor). He could be seen as the perfect Master parallel to the Ninth Doctor.

His mind is also still completely warped, but in a crueller and hateful way. He likes to taunt his victims and mentally destroy them before death, making them 'suffer to their last breath'. Although, he does like to reference pop culture when carrying out his deeds, either by singing or pointing out TV shows he enjoys.

Behind the Scenes

 * During the 'Babylon' campaign, the slogan: United Earth appeared several every time the Doctor and Amy landed on present-day Earth.
 * Until the season finale, the Master's 'Kapitan persona' was an unknown and background figure - even credited as 'Ad Model' when his advert was breifly shown (DW: Lucifer Rising).
