Reptilicus is the titular main antagonist in the 1961 Danish-American giant monster film of the same name. It is a giant dragon-like creature with the ability to regenerate from a single body-part.

Its vocal sound effects were provided by the late Georg Jensen.


Svend Viltorft and other miners dug up Reptilicus' tail when they were drilling in Lapland. It is flown to the Danish aquarium in Copenhagen, where it is put in a cold room for study. Due to careless mishandling, the door is left open and the section begins to thaw, only for scientists to find that it is beginning to regenerate.

The creature is dubbed "Reptilicus" and its regenerating ability is compared to other animals like earthworms and starfish. Once fully regenerated, it goes on a rampage across the Danish countryside to the panic-stricken streets of Copenhagen.

It is presumably killed when it is poisoned by ingenious scientists and military officers, and its blown-off foot sinks to the bottom of the sea, leaving the film open-ended, as the foot could possibly regenerate.



  • Reptilicus is the first Danish movie monster.
  • The special effects used to bring Reptilicus to life was a wired marionette.
  • There was a deleted scene where Reptilicus could fly. It was cut because it was too unrealistic.
  • Reptilicus can spit neon green acid, albeit clumsily and randomly.
  • Reptilicus is a homage to Manda.
  • Reptilicus was featured on the first episode of the 11th season of Mystery Science Theater 3000.
