Origin

One of the god-like Lords of Order, Nabu took corporeal form and settled down in Ancient Egypt, where he became known as a court magician to several Pharaohs, including Khufu. In 1940, Nabu (kept in suspended animation) was wakened by the young Kent Nelson, the son of archaeologist Sven Nelson. Nabu transformed Kent into a full-grown man and taught him the magic of Order, then gave Kent the golden Helmet of Nabu and Amulet of Anubis.

Kent as Doctor Fate

When Kent wore the Helmet, Nabu was part of him, and together they became the mystery-man called Doctor Fate in the 1940s. Later, Kent found Nabu to become possessive of him, and created a half-helm to wear instead. During this time, Dr. Fate would have less power but was no longer influenced by Nabu. Kent again joined Nabu during a clash with Kulak, after which the Helmet was lost. It would not be until the early 1960s that Kent would recover the Helmet and become the "complete" Dr. Fate again.

Kent Retires

Eventually, Kent grew old and retired to another dimension. Nabu found new disciples, first in Eric and Linda Strauss, who together became the new Fate. During this time, Nabu was banished to Earth for having prevented the age of Chaos, and took residence in Kent's old body, enjoying life as a human. Later, Nabu created still another Dr. Fate by returning Kent to youth and merging him with his wife Inza.

New Developments

After this, Nabu was reincarnated as the child of Eugene and Wendy DiBella, themselves reincarnations of Eric and Linda Strauss. Still later, Kent and Inza died and Jared Stevens (Fate) was chosen as the new Fate. Nabu returned and wanted to use Jared the same way he had used Kent, but Jared refused. Nabu grew mad and sabotaged the then-current "treaty" between Order and Chaos. As punishment, Nabu was turned into a Lord of Chaos. Recently, Hector Hall became the the last in line of the Fate legacy.

Nabu Returns

Nabu returned again, seemingly with his senses back. Currently, Nabu is a free spirit in the world of the Amulet, whispering to Hector through the Helmet. His presence has become increasingly oppressive, however, and Hector is suppressing him as much as possible.

Death

Nabu was apparently killed by the Spectre Force.
