Admiral Estaban Garza was a high-ranking delegate from the Joint Chiefs who met with Nick Fury and other high-ranking U.S. security officials to discuss the impending threat of the Chitauri, alien shape-shifters who were invading planet Earth.
Admiral Garza secretly met with Captain America to encourage him to steal Chitauri-detection technology developed by Tony Stark and give it to a company which would manufacture it and make it available to the public.
But Captain America eventually realized he had been fooled. Admiral Garza was actually a Chitauri spy himself, and was, in fact, the leader of the Chitauri invasion.
Admiral Estaban Garza (the Chitauri) spy is one of the most important characters in the novel The Ultimates: Against All Enemies. This Chitauri spy replaced the real Admiral Garza, an American human. The real Admiral Garza never actually appears in this book. From the character's very first appearance, he is a Chitauri impostor, although this fact is not revealed until relatively late in the novel.
