The Judas breed are the main antagonists of the 'Mimic' movie series. They were originally intended to kill cockroaches that spread the lethal Strickler's Disease but eventually mutated to resemble humans. They were created by entomologist Dr. Susan Tyler.
The Judas breed are essentially a hybrid of termites and mantis. The secretions they discharged caused cockroaches' metabolisms to go into overdrive, killing them regardless of how much their food intake was.
However, despite the success of the Judas and the fact that they were created all-female to prevent reproduction, they were able to later evolve and mimic their greatest nemesis: humans, who ironically created them in the first place.
