Davros' prototype

Whilst still using a dilapidated wheelchair, Technician Davros constructed a prototype machine for his project to create intelligent warrior robots with the mutated brains from badly wounded Kaled soldiers.

Roughly pear-shaped, it was constructed of heavily studded metal with a wavering eyestalk at the crown. Unarmed, it was made to obey Davros' commands but its the voice control circuits were still faulty, resulting in a delayed response. The prototype was presented to General Ravon and Security Commander Nyder, whom rejected it and ordered Davros to create a more impressive machine lest his project be terminated. Noting that Ravon displayed fear when the prototype advanced on him, Davros constructed a hi-tech life-support chair for himself before completing the "finished version" of his machine, which he designated Dalek One.
