Each of the officers were served by their own soldiers, who could be identified by the different masks they wore. Staff Officer Kotetsu's soldiers carried chains as weapons. Division Commander Arawashi's soldiers could fly.
Baron Rock and his soldiers could transform into rocks. General Wolf's soldiers carried spears. Commanding Officer Black's soldiers carried guns. Snake Woman's soldiers could transform into snakes. The soldiers were loyal not to the Delza Army but to their imediate commander. So they would only cooperate with each other if the officers were working together.
Just as there had been a rivalry between Mr. Titan and General Shadow there were rivalries among the Delza Army officers. Staff Officer Kotetsu and Division Commander Arawashi fought over which would kill Stronger. Staff Officer Kotetsu and Doctor Kate wouldn't let the other defeat Stronger. Major Skull and Dr. Kate worked together but after that Baron Rock interrupted Major Skull's battle with Stronger. General Wolf tried to get Baron Rock to revolt against General Shadow. Finally General Shadow loses control to Marshal Machine (wearing costume: Ishizuka Nobuyuki, voice: Ichikawa Osamu), who came from Egypt.
The Delza Army General was in reality just a robot, controled by the true Dai Shuryou (Great Leader), a giant alien brain.
