Groph

Dr. Groph is a character that is mentioned in the radios found in the Call of Duty: Black Ops Zombies map, Moon and in the Call of Duty: Black Ops III Zombies map, Der Eisendrache.

He was a Group 935 scientist that was appointed as the head scientist at Griffin Station, and was assigned the task of discovering how the M.P.D. worked. He is Schuster's superior. He has very good memory according to Richtofen.

In the map Der Eisendrache, it is revealed that Groph survived Samantha gaining control of the zombies. The young Richtofen is able to communicate with Groph via radio. Groph however, becomes suspicious of Richtofen's sudden change of personality before saying he must do whatever it takes to prevent him from escaping Griffin Castle alive. When the rocket containing the Original timeline Dempsey crashes by Richtofen and the crew, Groph is furious and threatened to kill Richtofen along with the other three. Richtofen, however decided to get rid of loose ends by blowing up the Moon, thus killing Groph and destroying Griffin Station.

Trivia
