Movellan Control Unit

A small rectangular device embedded in Movellan equipment, fitted with precise adjustment dials along one edge. Its surface hums faintly with operational energy, reflecting internal mechanisms tied to hierarchical command protocols aboard the Nova Device. The unit is critical in managing system triggers, with operations including: embedment in carriers' belts (personal control units), embedment in spacecraft command consoles (central control systems), and ability to disable/manipulate Movellan systems. Notable interactions include Tyssan's methodical dismantling/reassembly, Romana's physical seizure during pivotal moments, and direct involvement in the coordinated uprising where units are disabled with sonic devices.

Tyssan takes control of Movellan Lan

The Movellan control unit is swiftly removed from Lan’s belt by Tyssan’s ambush, then dismantled, inspected, and adjusted with minute tool adjustments before reinstallation. This brief disruption triggers Lan’s collapse and enables temporary rebel command takeover aboard the Nova Device.

Before: Secured on Lan’s belt, functioning as designed to regulate his cybernetic command functions
After: Temporarily removed and tampered with, then reinstalled but temporarily rendered ineffective during Lan’s disorientation

Lan restrains Agella seizes control

Agella’s Movellan control unit, a critical tactical device embedded in her equipment belt, is violently stripped away by Lan with clinical efficiency. Its loss renders her immediately passive and dependent on Lan for support, while its seizure by Tyssan and the prisoners becomes a catalyst for redirecting the vessel’s systems and undermining Movellan command.

Before: Functioning device attached to Agella’s belt, operational and in active use for systems oversight.
After: Removed from Agella’s control, seized by freed prisoners, and repurposed by Tyssan to challenge Movellan authority.

Doctor turns the tables on Movellans

Four Movellan control units are embedded in the command consoles and function as the core of the vessel's discipline and systems. The Doctor disables them with his sonic whistle, causing their crimson lights to flicker and die. Romana pries them free moments later, holding the liberated devices while the systems falter.

Before: Inserted and active in Movellan command consoles, maintaining ship functions
After: Disabled and physically removed by Romana, now in the possession of the Doctor's alliance

Doctor leaves allies to confront Davros alone

The Doctor disables four Movellan control units using his sonic dog whistle, causing their crimson lights to flicker and die. Romana physically pries a liberated control unit from its housing moments later, handing two to Tyssan and retaining one herself, thus securing operational control of the ship for the rebellion.

Before: Secured in consoles aboard the Movellan spacecraft, powering systems with crimson indicator lights active.
After: Removed from their housings and held by Romana, Tyssan, and the Doctor, stripped of power and unused in this immediate context.

Romana stops Sharrel from detonating device

The Movellan control unit is forcibly extracted from Sharrel’s belt by Romana during the struggle. She takes possession of it long enough to hurl it into the dunes, severing Sharrel’s link to the Nova device. This act nullifies Sharrel’s ability to fire the weapon and severs a critical command link.

Before: Attached to Sharrel’s belt, serving as the operational interface for the Nova device’s systems
After: Removed from Sharrel’s possession, discarded into the sand away from the weapon
