Greenaway

You may be looking for Cousin Greenaway.

Greenaway was a friend of the Doctor. His daughter was named Martika.

Greenaway helped the Doctor defeat a sea creature that threatened to invade his village. In the attack, Greenaway lost his legs. A third of his skull was replaced with metal. His mind couldn't accept this and he became trapped in his mind.

Greenaway was visited telepathically by several incarnations of the Doctor, all of whom tried to convince him to come out of himself.

On his last visit, the Doctor told Greenaway that the machinery could no longer keep him alive. The Doctor had come to tell him goodbye. When the Doctor left, he turned off the machine.

The shock of losing his life support machine brought Greenaway out of his coma. As he recovered, he hoped for the Doctor to visit him again. (PROSE: Greenaway)
