The Invisible Man: Dr. Jack Griffin succeeds in his invisibility attempts, at the price of losing his sanity. We were hoping he would go insane and start doing hilarious bathroom invisibility pranks, but instead he just starts hurting everyone.
Giant Ants: From the classic film, Them!, these ants had the misfortune of living near a nuclear bomb test center. Of the millions of monsters Godzilla has fought, he never squared off with these insects.
Darkseekers: The evil (or are they?) mutants from the I Am Legend series, these creatures were humans infected with what was supposed to be a cancer cure. That's still gotta be less painful than chemo.
Rabid: This film features a woman who receives experimental skin grafts. She grows an orifice under her armpit (really) and starts turning people into zombies. We kept waiting for the climactic showdown versus a bikini waxer.
The Ape Man: Bela Lugosi puts on one of his many amazing performances as a scientist who turns himself into an Ape Man. If this list has taught us anything, Lugosi should then try to find a cure for Alzheimer's because it will accidentally make his ape brain super smart.
