Doctor's Ultraviolet Converter Device

The Device resembles either a handheld metallic emitter with a translucent energy chamber that pulses violet light when active or a heavy black box with glowing violet ports. The Doctor commonly wields it, though it may be jury-rigged to the Sea Base’s power grid. When activated against the Myrka, the converter releases focused ultraviolet radiation that immediately disrupts the creature's revival systems. The device hums audibly and casts harsh violet shadows. Soldiers flinch from its glow as it halts the Myrka’s advance.

Guards discover Solow's lifeless body

The Doctor wields the UV converter cautiously, flipping it on and off near Solow’s path to test its disruptive effect against the Myrka. The violet pulse briefly checks the creature’s motion before he switches it off again, satisfying himself of its utility while leaving the corridor and Solow’s doomed flight beyond its reach.

Before: Activated in the Doctor’s hand moments before Solow ducked out of sight, confirming it can stun or repel the Myrka.

After: Deactivated and returned to a ready state, its translucent chamber dim and its emitter cool once more.

UV device neutralizes Myrka Silurians strike back

The Doctor deploys the experimental UV converter device in the corridor to emit focused ultraviolet radiation targeting the Myrka.

After neutralizing the threat, the Doctor carries the still-active device as they prepare to return to the bridge.

Before: Stored or carried by the Doctor in an inactive state, presumably in a compact form suitable for sudden deployment

After: Activated, discharged, and now returned to portable function as the Doctor and Tegan prepare to leave the corridor
