According to ancient legends, dragon-like Tiamat (also known as Leviathan, the primeval embodiment of the sea, or primordial sea) mated with Apsû (the embodiment of fresh water below the earth's surface), giving birth to the first two Annunaki: Lahmu and Lahamu. They also sired Kingu.
Apsû grew annoyed by the younger generations, and planned to destroy them, but was preemptively killed by Ea. Enraged, Tiamat and Kingu, who led Tiamat's army of monster progeny (including horned serpents, snake-dragons, demonic lions, lion-men, scorpion-men, and bull-men), lay siege to Dilmun. Anu's grandson Marduk proposed to lead the armies of the Annunaki in exchange for becoming the Annunaki supreme leader, and slew Tiamat using heavenly weapons (mace, trident and axe) forged by Ningal.
Tiamat's name was invoked during the Hyborian Age.
In modern times, Tiamat's body had settled in Northern Greenland, and finally broke out of the ice. Lilith emerged from it when a group of scientists (whom she murdered) led by Dr. Phillip Henderson and Dr. Adam Brigman came to inspect the strange creature and inadvertently freed her.
