Time Walker | 1982
A university's newest acqusition is a sealed Egyptian sarcophagus. It is opened to reveal what appears to be a mummy, but is in fact, an extraterrestrial alien who is in suspended animation, and is covered with a dormant fungus. When student Peter Sharpe x-rays the mummy, he finds some crystals that he steals and sells to other students. In order to hide his theft, Peter takes a second x-ray without the crystals, but this new dose of radiation wakes the alien up and reactivates the flesh-eating properties of the fungus. The mummified alien now goes on the hunt for his crystals, which are vital parts of the transortation system he needs to get home.
