Shuma-Gorath

Shuma-Gorath is an evil deity from the Marvel universe and one of the Old Ones. Although he was a very obscure villain, he became popular after his appearance in the Marvel Super Heroes fighting game.

Story
Shuma-Gorath's origins are unknown. In ages past, he ruled Earth and commanded human sacrifices, until a time-traveling sorcerer called Sise-Neg banished him. Centuries later, Shuma-Gorath returned to our world, ruling it once again and feasting on humans. After another age, a newly-risen god called Crom used the Iron-bound books of Shuma-Gorath to imprison the demon on a mountain. Over a century later, still trapped in the mountain, he uses his mental powers to communicate with the sorcerer Kulan Gath, who decides to free the demon by using the Iron-bound books. The barbarian Conan, after having a nightmare with Shuma-Gorath, senses the danger and, with the aid of Crom, uses the books to banish Shuma-Gorath back to his own dimension.

Ages passed, and now in the modern age, Shuma-Gorath once again tried to enter our dimension. He possesses the mind of the Ancient One, a powerful sorcerer who was the mentor of Doctor Strange. Unable to stop the demon, he is forced to kill his master to prevent Shuma-Gorath from entering Earth. Years later, when fighting the sorcerer Urthona, his talismans are almost all destructed, which collapses the barriers imprisoning the Old Ones, allowing Shuma-Gorath to enter our world again. With no options left, Strange decides to travel to Shuma-Gorath's dimension and fight the demon there to prevent him from invading our world. Strange starts absorbing the chaos power, which makes him merge with Shuma-Gorath. He then kills himself, which kills Shuma-Gorath too. Shuma-Gorath resurrected from what remained of the chaos power, as Strange's soul was purified and resurrected as well. Some time later, he once again enters our world, with the help of Nicholas Scratch, but is once again banished by the combined efforts of Doctor Strange, the Fantastic Four and Diablo.

Powers
Shuma-Gorath's power level is far beyond human comprehension. He is virtually indestructible, and can regenerate completely, also being able to change his own form. He generates energy within himself and can also absorb energy, which he easily manipulates to create several forms of attacks. He is able of teleportation, levitation and phasing, being also able to travel through dimensions at will. He can communicate telepathically and mind-controlling others, even from other dimensions. In his own dimension, Shuma-Gorath is completely omnipotent.
