Inhibitor collar

An inhibitor collar is a device designed to suppress superhuman abilities, including naturally developed mutant abilities. They are often used by organizations and agencies who were formed to combat super=powered threats, but they have also been used by enemy agents as well. The technology used in such devices varies, but in most cases, the inhibitor collar negates a person's powers in totality until it is removed. Some exceptionally powerful individuals may possess enough ability to cause a collar to overload.

On The Gifted, the agents of Sentinel Services use inhibitor collars to restrain unlawful mutants. Even after a mutant is captured and imprisoned, they are forced to continue wearing the inhibitor collar. Lorna Dane was one such victim, though she was able to generate a small measure of electromagnetic radiation despite the collar. Former Federal prosecutor Reed Strucker referred to the inhibitors as "flea collars".
