General Martin Perez, played by Dan Hedaya, is a character in the film Alien Resurrection.
General Perez is the commanding officer of the USM Auriga, overseeing the ship's legal (and illicit) activities. After Ripley 8 is cloned and her Queen embryo is extracted, Perez is uneasy with her enhanced physical and psychological abilities but allows her to live; Dr. Mason Wren and Dr. Jonathan Gediman continue their research on her.
Perez hires Frank Elgyn to abduct a number of humans in cryostasis as incubators for the cloned Aliens; he gives the Betty's crew food and lodging, emphasizing that they cannot interfere with the research on the Auriga. When the Aliens board an escape craft, he sabotages them with a grenade. An Alien bites the back of Perez' head, exposing his brain.
