Villains who are not deceased but are no longer active (at least physically) due to being imprisoned or incarcerated, whether it be by regular means (in the case of more human beings) or mystical means (in the case of more demonic/god-like beings). Although they are unable to be a physical threat, Imprisoned Villains may be able to continue their crimes from prison and often plot ways to escape.

Note: Imprisoned Villains cannot be labeled as Karma Houdinis, regardless of how painless the imprisonment is.
