Leviathan is a race of creature in the Water Civilization,


Non-evolution creatures have キング (King) as a prefix, while Evolution Creatures have レジェンダリー (Legendary).

(Kai) meaning "Sea" and 嶺 (Rei) meaning Ridge/Peak is used on creatures with other races.

In Episode 2, they are often named after classes of battleships. This includes, Truename Bismarck, King Mackensen and King Scharnhorst.


Leviathans are the most powerful race in the Water civilization. Highly intelligent, they cannot be controlled by any other race, including Cyber Lords.

With little gravity in the seas to affect their growth, they have become enormous and are sometimes mistaken for landmasses.

For some reason they seldomly talk, with the first talking Leviathan being K Atlantis, Ocean Peak of Taiga, possibly because it was also a Cyber Command. However, in DMX-12, King Tsunami was known to answer Parlock's questions.

In Episode 2, the Leviathans joined the Unknowns.


While they were the predominant race of creatures in the Water Civilization in the Beginner's Block, there were fewer and fewer Leviathans printed after the Fighting Spirit Saga until they completely disappeared after DM-13 (Gaulzaganta, Spirit of the Woodland Ridges). However, they made a comeback in DM-31 as Knight creatures and a few other had appeared in other Expansions.
