10 More Shocking Horror Movie Monsters With Surprising Powers

10. Judas Breed - Mimic

In Guillermo del Toro's sci-fi horror Mimic, a disease carried by cockroaches starts infecting children, inspiring an entomologist called Susan Tyler to look for a solution. Over time, she creates an insect called the Judas Breed that poisons roaches. 

Despite being genetically programmed to die after one generation, the bugs lived on. Not only that, but they also turned into human-sized monsters and decided that humanity would serve as their new prey.

Rather than killing in the open, the Judas Breed bait passers-by through the use of a sneaky tactic - mimicry. After the super-insects mutated, their exoskeletons developed physical characteristics that resembled a human face. When observed from a distance in the dark, the Judas Breed can pass off as a regular person, allowing it to slaughter its victims with ease.

Mimic may not be one of Del Toro's better-known movies, but it makes a lasting impression due to its creepy premise. After all, the animal kingdom is littered with crafty spiders, snakes, moths, and mantises that use imitation to nab their prey. The idea that a creature could evolve to lure human beings to their demise isn't just unsettling, but theoretically possible.
