Nyder

Nyder was a Lieutenant in the Kaled's Military Elite and assistant to Davros.

Biography
Following a rescue operation of Davros from a Thal dome, Davros promoted Nyder to Security Commander prior to Davros' take-over of the Kaled government. (BFD: Guilt) He was Davros' most trusted associate, and personal aide. Icily efficient he obeyed Davros's every order. He was exterminated by the Daleks as he tried to carry out Davros's instructions to shut off the Dalek production line.

Despite certain misgivings about Davros's more complicated plans, for he preferred the more direct approach due to his military background, he never wavered and had no issue with the genocide of his own people and the Thals to achieve Davros's goals. Cunning and sly, though not as intelligent as Davros, he still tricked members of the Scientific Elite into revealing their treachery against Davros and helped in their destruction. (DW: Genesis of the Daleks)
