You may worry that you haven’t seen the first two Aztec Mummy films, but trust me, there are so many recaps here that you’ll get caught up really soon.

Somehow, Dr. Krupp has come back from a snakepit to become The Bat and lead a whole new gang. To get what he wants — that gold breastplate that has led him to battle Popoca, Dr. Eduardo Almada, Flor and Pinacate across this film series — he’s made a robot with a human brain that can deliver electronic shocks through its clawed hands.

If you learn anything from this film, maybe you shouldn’t. Aztecs never practiced mummification and used hieroglyphic writing, instead using cremation or simple burial, as well as pictographs. Maybe the filmmakers meant the Incans and the Mayans? Well, they buried Popoca as if he were an Egyptian style mummy, but one thinks that they based that knowledge on Universal horror movies and not any textbook.
