Before the arrival of
the First Host of the Celestials, Shuma-Gorath ruled the Earth and commanded
human sacrifice, until the time-traveling sorcerer Sise-Neg banished him. He was
able to return as a god during the Hyborian Age to slaughter those who seek his
favor. Eventually, the power of Crom imprisoned him within a mountain. However,
in his imprisonment he could interact with Conan the Barbarian, Kulan Gath, and
many others, before Crom banished him back to his home dimension.
When Shuma-Gorath tried
to return to Earth through the mind of the heroic sorcerer the Ancient One, he
forced Doctor Strange to kill his master to prevent the powerful creature from
arriving on Earth. Years later, Dr. Strange was forced to destroy the talismans
keeping the chaos demons at bay, to keep them from falling into the hands of an
evil sorcerer. Dr. Strange was then forced to travel to Shuma-Gorath's dimension
and fight it there to prevent the demons from invading Earth. To do so, Strange
absorbed the chaos magic into himself, gaining enough power to destroy
Shuma-Gorath. However, he started to transform into a new Shuma-Gorath himself as
a result, so he committed suicide to prevent that from happening. An ally of
Strange was able to purify him on his way back to the living. Shuma-Gorath
resurrected himself not long after from the remnants of the chaos magic.
Shuma-Gorath was later
summoned to Earth by the sorcerer Nicholas Scratch, who offered his services in
return for "(his) life and Barbados". However, the demon was driven
back by the combined efforts of the Fantastic Four, Doctor Strange, the Salem's
Seven, and Diablo.
