Niklas Jansson made the awesome choice to redesign The Daleks but also many of the designs from the older periods of the Doctor Who.
for the new Daleks he wanted his redesign to look like something which could be threatening to a space adventurer, so he decided to change both the design and ’stats’ a bit.
The Slythers might be the Daleks’ guard dogs of sorts. They’re a little slow though, so they rely on camouflage and making spooky sounds.
The Cybermen ships to the right here are partly inspired by the ships seen in Wheel of time, The Invasion, and Revenge of the Cybermen.
