I wasn’t particularly impressed by this villain. When I saw the trailer, which seemed to be showing a robotic version of Harris from Mass Effect I was intrigued, but the end result didn’t deliver as an alien death machine capable of conquering worlds. I guess the robot was just a prop, as the episode was more about the interactions between the Doctor, Clara and Danny, which were great, so as such I guess it did its job.
A Skovox Blitzer was a deadly weapon, built with limited intelligence and able to act autonomously if required. A humanoid tope section land with weaponry sat above a propulsion unit. The Doctor encountered a stranded not on Earth which was attacking humans and transported it to deep space away from any conflict.
