Asmuth

 was a Time Lord soldier in the Time War.

Biography
When the War Doctor confronted Rassilon about time distortions on Estragil and ressurecting soldiers, Asmuth was assigned by Rassilon to accompany the Doctor to investigate and destroy the cause of the time distortions. Four versions of Asmuth accompanied the Doctor. As the four versions attended by the name "Asmuth", the Doctor gave each version a nickname: Blue, Green, Pretty Boy and Phyllis.

As they faced the Daleks and the Reapers, the different versions of Asmuth progressively started to be defeated. The first one to die was Blue, hit by a Dalek. Later, Pretty Boy was also hit by another Dalek and died. The Doctor, Green and Phyllis continued exploring the ruins of Estragil. Shortly after that, Phyllis and Green were both shot, and died.
