Professor Metz is first seen in one of Ernst Stavro Blofeld's labs working on his diamond laser satellite. Once it is completed and sent into space, he travels with Blofeld to the oilrig control centre. The doctor is also seen in the secret laboratory of Blofeld when Bond enters disguised as a technician. Nobody knows what happened to Professor Metz. There is a possibility that he died in the explosion of the den and another that he is arrested by the CIA.
