Tiamat, also dubbed Titanus Tiamat, is a giant serpentine daikaiju created by Legendary Pictures that appears in Legendary's 2019 film, Godzilla: King of the Monsters, as a name briefly seen on a monitor. She made her first full appearance in Godzilla Dominion.


"Tiamat" was a primordial water goddess with a dragon-like appearance in Mesopotamian mythologies, the symbol of the chaos of primordial creation. The name "Tiamat" is also applied to many modern monsters; for example, an evil, five-headed dragon goddess in Dungeons & Dragons.



Tiamat greatly resembles a giant serpentine leafy seadragon with crocodile-like jaws, barbels, and yellow eyes. Her scales are purple while her fins are blue in color.


The roars of Tiamat are written as "xhhhhhsssss".


Like most Titans, Tiamat is very territorial and will not give up without a fight. However, she knows when the odds are not in her favor and yields to Godzilla when he asserts his dominance.


Ancient Times

Centuries ago, Tiamat fought and killed a Titanus Kong member when she ventured into his lair.

Godzilla: King of the Monsters

Tiamat was found in Stone Mountain, Georgia, USA, by Monarch, who built Outpost 53 around her. When Ghidorah calls all the Titans, Tiamat breaks free and begins to hunt with her new pack. When the ORCA calls all Titans to Boston, Tiamat does not arrive in time for the battle and does not see Godzilla become the new alpha of all Titans (except Kong).

Tiamat appears as a rival Titan who fights Godzilla after she settled in one of his lairs. After a short yet intense battle, Godzilla manages to overcome Tiamat and sends her into dormancy along with the other Titans.


Amphibious nature

Tiamat can survive both on land and in water.


According to Drew Edward Johnson, Tiamat can manipulate water, specifically maelstroms and waterspouts, to allow her to drag foes to her, even airborne ones.[1]

Razor-sharp scales

Tiamat's body is covered in razor-sharp scales that can cut deep gashes into the skin of other Titans, including Godzilla.

Strength and combat

Tiamat can use her jaws and tail as dangerous weapons in combat. She also uses her serpentine body to strangle her opponents like constrictor snakes.

Toxic vapor

Tiamat is able to release a cloud of toxic vapor from her mouth that is capable of blinding Godzilla momentarily.


  • The outpost Tiamat was contained in, Monarch Outpost 53, is a possible reference to the 1953 Warner Bros. film The Beast From 20,000 Fathoms.
    • Tiamat’s Toxic Vapor attack is similar to the Rhedosaurus’ toxic blood.
  • Tiamat's design shares several similarities with Titanosaurus (seahorse-like head) and Manda (body resembles a legless Asian Dragon).
    • Tiamat also shares many resemblances with the Elder Dragon, Amatsu, from the Monster Hunter games.
