His known associates include his own nephew, Young Gargunza, and an evil alien called Young Nastyman.

Dr. Gargunza's advancements in science and genetics caught the attention of the Nazi party. In 1934 they recruited him into the Reich as a genetics researcher. He continued to work for the Nazis until 1941 when he realized it was impossible for the Axis to win the war and defected to England.
Created by Mick Angelo in 1954 as a substitute for Doctor Sivana after Fawcett Publications ceased publication reprinting Captain Marvel comics in England.
