The Throne of Hell (1994)

Original title: El trono del infierno

A group of archeologists excavating Aztec ruins in Mexico City uncover a bizarre statue, which unleashes satanic powers and possesses the chief archaeologist. The demonized man goes on a rampage of bloody murders while being pursued by one of his female colleagues and a police officer. Horribly burned in an explosion, he still continues his ungodly crimes, including crucifying a woman upside down. A bishop sends for a mystic called “The Angel”, a character who dresses in medieval clothing and is armed with a demon-destroying sword. The possessed archeologist transforms into a club-wielding monster and challenges The Angel in a duel to the death.
