''Universal Monsters Online'' is a MultiplayerOnlineBattleArena which went live in 2012. As its name suggests, it takes place in the UniversalHorror universe and puts players into the cloaks/bandages/excess body hair of old-school film monsters. These range from perennial classics to more obscure entries in the genre.

The playable characters include...
* Film/{{Dracula|1931}}
* [[Film/{{Frankenstein 1931}} Frankenstein's monster]]
* [[Film/TheWolfMan1941 The Wolf Man]]
* [[Film/TheMummy1932 The Mummy]]
* Film/CreatureFromTheBlackLagoon
* ThePhantomOfTheOpera
* Film/BrideOfFrankenstein (whose name in life is revealed to have been Madeleine Ernestine, continuity fans!)
* Film/TheInvisibleMan
* Film/DraculasDaughter, Countess Zaleska
* The Metaluna Mutant (from ''Film/ThisIslandEarth'')
* The [[Film/TheMolePeople Mole Man]] King
* Dan [=McCormick=], the ManMadeMonster
* Gwynplaine, [[TheManWhoLaughs the Man who Laughs]]
* WeirdWoman
* The Robot (from ''Film/ThePhantomCreeps'')
!!This game provides examples of:
* MonsterMash
* {{Mooks}}: Zombies and trolls.
* UnlockableContent: By earning money in the game the player is able to access items, costumes and unlockable monsters.
* YouDontLookLikeYou: Some monster designs are modeled closely around the film versions, while others take far more artistic license: Countess Zaleska looks completely different to her actress Gloria Holden, while the Man Made Monster is much more evil-looking than the unfortunate schmuck played by Lon Chaney Jr. In some cases, the original designs are available as unlockable costumes.
