Rover & No.6.
In the original series 'Rover' is the village guardian, which keeps the citizens of the village in-line, keeping peace and order. And is capable of pursuing any escapee over land and sea. It suffocates it's victims into unconsciousness, or to death.
In the 2009 production of THEPRISONER however, 'Rover' is conjured up in the mind of Six. When Six tries to escape the village, or is going to lose someone close to him, Six conjures up 'Rover,' and that includes the death of 16 in the episode Darling.
