A man named Gregori Kronski was subjected to surgery that made him a double of Colonel Glenn Talbot. The Gremlin used his Psiclone device to imprint the memories and personality of Talbot upon Kronski's mind, and those of Kronski upon Talbot's. Kronski was then sent to the United States, claiming to be an escaped Talbot. However, a bomb was concealed within Kronski's body. The Gremlin's plan was to use the bomb to assassinate the President of the United States when the latter came to visit Gamma Base, where Talbot was stationed. Colonel Jack D. Armbruster saved the President's life, but both Armbruster and Kronski were killed when the bomb exploded.
