Plesiosaur-like cryptids, such as the Loch Ness Monster, are usually this species. They are sanctioned by the Troop, and allowed to coexist with humanity in the human world due to their elusive talents.
The most famous of these is known as the Loch Ness Monster (or Nessie) who was captured and later released in 565 A.D. Because they are fairly gentle and able to hide well, Hydrodragons have been sanctioned by The Troop to live among us. Other Hydrodragons are known to their regions by the following names: Ogopogo, Cressie, Mussie, Kingstie, Mugwump, Lizzie and Champ.
