[[folder: Comic Books ]]

* Locksmith in the MarvelUniverse who used to imprison super-humans.
* The Hangman, another MarvelUniverse vigilante, would murder male evildoers but imprison female ones to 'protect them from corruption'. Unfortunately, he had a nasty habit of forgetting about them, leaving them without food or water...
* In the Marvel2099 universe, the Punisher (2099 version) had his own private prison. Of course, in his {{Cyberpunk}} {{Dystopia}} CrapsackWorld, anyone who could shell out the fine could get away with ''any'' crime, including murder. This made him - relatively speaking - as much an extremist in his world as the original Punisher (who just shoots everybody) was in his.
** Possibly more so; his prison came with a torture chamber.
* Rayek in ''ElfQuest'', who never wanted to kill Winnowill (partly because he loves her, but mostly because if she dies her evil soul will be free to wreak havoc), and in the end becomes her living jailer, [[spoiler: keeping her spirit within his own body as he tries to teach her to love.]]
* Faora Hu-Ul was a Phantom Zone villain introduced in ''[[ComicBook/{{Superman}} Action Comics]]'' #471.She was a beautiful Kryptonian woman whose unexplained hatred for men led her to torture and kill 23 men at a secret concentration camp in her home.

* A borderline case occurs in the YoungBond novel ''Hurricane Gold'' by Charlie Higson. The main villain El Hurrican runs an island hideaway for criminals on the run. Once on the island, they can never leave. While their money lasts, they live a life of luxury, but once their money runs out, he puts them to work as a slave labour force.

* In ''SoonIWillBeInvincible'', major supervillain Baron Ether lives out his twilight years under house arrest in his mansion, with his nemesis The Mechanist as his jailer.

* Hydraxon from ''{{Bionicle}}''. To be fair, it is his job description, and he's hunting escapees in a place where he can expect to ''find'' only escapees, but he's still a little too quick to assume that everyone he meets is an escaped criminal. Botar, in charge of prisoner apprehension and transport, also likes his job a bit too much.

* The Ur-quan Kzer-za in ''StarControl 2''. Either you joined them, or you got slave-shielded and trapped on your home world.

[[folder: Western Animation ]]

* Lock-Up from ''BatmanTheAnimatedSeries'' (and CanonImmigrant to the Comicbook/{{Batman}} comics).
* ''DannyPhantom'' has Walker, the obsessive sheriff type.
* One episode of ''{{Gargoyles}}'' turns Goliath into this when he uses Odin's Eye to become a PhysicalGod. The best way to [[LiteralGenie "protect his friends"]] is to seal them in a cave for the rest of time. Nothing can get to them there.
* Mr Moss from ''StormHawks''.
* The Warden of ''{{Superjail}}!'' It's not like he's trying to uphold the law or anything. It's mostly because he loves incarceration '''that freaking much.'''
