The Mandarin then establishes a base in China's Gobi Desert, and turns his attention to the Hulk for a time, hoping to make the dull-witted brute into an accomplice. Two attempts at controlling the Hulk proved futile. First he places a device on the Hulk's neck, hoping to use him to start a war which will allow the Mandarin to take over the world. However, Nick Fury foils this scheme. Next, the Mandarin allies himself with the American criminal the Sandman, who had just been beaten by the Hulk earlier. The Hulk destroys the Mandarin's desert base and the Mandarin sends the Sandman into a hot vat, turning him to glass. The glass later shatters, and the Sandman has to recover slowly in the Mandarin's satellite den. When the Mandarin next attacks Iron Man, he employs an android in the Hulk's likeness rather than the real Hulk. The Mandarin sets up a makeshift base of operations in the United States, and attempts to discredit Tony Stark publicly. Holding Iron Man captive for the fourth time, the Mandarin tries to learn if Iron Man is actually Stark, but Stark fools him with a rubber mask over his own features. His plans thwarted, the Mandarin tries to kill Stark's then-girlfriend, Janice Cord, but the Mandarin's betrothed Mei Ling saves her at the cost of her own life.
