K9 is a mobile computer in the form of a dog. He was for many years the constant companion of the renegade Time Lord known as The Doctor, though the original K-9 eventually parted company with him, to be succeeded by a separate and distinct K-9 MK II (who later also left). A third K-9 was given by the Doctor as a gift to Sarah Jane Smith.

The K9 who appeared in the Marvel Comics Doctor Who series was the MK II version, seen in the TV series between 1978-1981.

The version of K-9 seen in the Marvel strip was often drawn as much smaller than his TV counterpart so that the Doctor could carry him.
