Atrika

Atrika was a Tibari scientist who employed Xantha soldiers which captured the Second Doctor, Jamie McCrimmon and Zoe Heriot. He wanted the Doctor and Zoe, as higher intellects, to experiment on using his mind projector, which utilised a Dalek crystal. He wanted to use Zoe to assassinate the Tibari president. When the Daleks took over the operation, he betrayed the Daleks by telling the Tibari about the assassination attempt and they killed Atrika. However, his consciousness was transferred into a Dalek via the mind projector. Slowly losing himself, he instructed the Second Docto and Jamie to press the button marked "Extricate" to reverse the projector and return their minds to their own bodies. In his last moments of life, he amplified the other Daleks' brainwaves, showing them their malice and prejudice of non-Dalek life. (AUDIO: Fear of the Daleks)
