History:
(Marvel Premiere I#35) - In 1958, Zirksu assumed the identity of Diabolik and employed a number of gunmen to serve the cause of Communist Russia. His activities attracted the attention of the 3-D Man, who had himself received his powers while escaping from a Skrull vessel. After the 3-D Man defeated all the gunmen, Diabolik revealed himself to be a Skrull, and he gloated at how his shape-shifting powers could easily manipulate people because of the cold war climate. The 3-D Man struck Zirksu and knocked him out of a window; but Zirksu escaped by shifting his form so that the 3-D Man could not pick him out of the crowd below.

(Marvel Premiere I#36) - As Buzz, the leader of a motorcycle gang, Zirksu led the hoodlums in stealing papers concerning UFO sightings (actually Skrull vessels) from Professor Potter outside of an observatory -- this attracted the attention of the 3-D Man again. The hero defeated the thugs, but Zirksu escaped with the papers on a souped-up motorcycle, and he taunted the 3-D Man with his true face as he fled.

   Later, Zirksu posed as disc jockey "Doc Rock," television host of "Doc Rock's Teen Beat" and promoter of rock-star Vince Rivers. When Rivers was scheduled to perform at the Astra Theatre in Los Angeles, Zirksu installed Skrull-technology inside Rivers' speakers, which caused the teenagers who heard him sing to run amok. The 3-D Man destroyed the technology and Rivers was arrested, while Zirksu avoided detection.

(Marvel Premiere I#37) - Zirksu sent an Augmatron to Rivers to break him out of jail, but Rivers was stopped by the 3-D Man, who confiscated the device from him. Transforming into a bird, Zirksu followed the 3-D Man and attempted to kill him with an energy blast from his glove just as the hero reunited with his younger brother, Hal Chandler; but instead of killing him, the blast somehow changed the 3-D Man's powers so that Hal became the dominant mind controlling the 3-D Man.

   Later, in the guise of Vice-President Richard Nixon, Zirksu went to meet with Professor Sinkovitz in his laboratory; he helped Sinkovitz solve some problems the professor encountered with the development of his absolute zero apparatus. Then "Nixon" operated the controls of the device, which empowered Sinkovitz and transformed him into the Cold Warrior.

   After convincing the Cold Warrior that the 3-D Man was a communist agent, "Nixon" told him it was his patriotic duty to stop the "commie spy," and he sent the Cold Warrior to Santa Monica Pier; then he remotely adjusted the confiscated Augmatron to emit a signal that led the 3-D Man into battle with the Cold Warrior.

   However, after the Cold Warrior failed in his mission, "Nixon"/Zirksu transformed himself and took on the appearance of a less formidable human -- he believed he would never have use of the form of Richard Nixon again ("At least...probably never.").
