For the episode, see MST3K 102 - The Robot vs the Aztec Mummy.

The Robot vs. the Aztec Mummy (originally La Momia Azteca contra el Robot Humano) is a Mexican horror film starring Ramón Gay and Rosa Arenas, which blends elements of science fiction and horror. The film is the sequel to The Aztec Mummy and The Curse of the Aztec Mummy, and a large portion of it consists of an extended recap of the events from the first two entries in the series.


The evil Dr. Krupp, a mad scientist known as "The Bat", managed to escape the snake pit into which he was thrown at the end of The Curse of the Aztec Mummy and continues his efforts in this film to steal a valuable Aztec treasure from the tomb of a centuries-old living mummy, Popoca. Krupp builds a robot with a human brain in it, planning to use it to destroy the mummy, should he return to thwart his efforts. The original discoverer of the mummy, Dr. Edward Almada, his wife Flora, and his associate Pincate work to stop the mad scientist from completing his plans.

Dr. Krupp gets inside the mummy's tomb and once again steals the gold breastplate from its resting place on the mummy's chest. When Popoca wakes up in a rage, Krupp orders his human robot to fight him. The two monsters engage in a fierce struggle to the death, but the robot's ability to deliver burns and electrical shocks from his hands quickly begin to wear the mummy down. Just as it seems the robot is winning, Dr. Almada bursts into the tomb and knocks the remote control from Dr. Krupp's hands, effectively shutting off the robot's brain. In a wild rage, Popoca tears into the robot, literally reducing him into scrap metal. Popoca strangles Dr. Krupp and his henchman, then stumbles off to another tomb where hopefully no one will ever disturb his sleep again.
