Mephisto is a demon and is commonly mistaken for (and sometimes poses as) the biblical version of Satan. He cultivates this interpretation for the influence it gives him over humans who believe in the teachings of Christianity; whether the entity Satan actually exists in the Marvel Universe remains unestablished. It is believed that Mephisto and many other Hell Lords were created from the primeval concentration of evil energy left in the wake of the fleeing Elder Gods when they were driven from the Earth by the entity Atum millions of years ago.Both the Silver Surfer and the Thunder God Thor become perennial foes for Mephisto, who detests the fact that they are shining examples of what mankind could one day become.Mephisto causes long-term problems for other characters, including:Granting immortality to a group of sorcerers - later known as Mys-Tech - in exchange for providing him with the souls of others.Capturing and holding the soul of Cynthia Von Doom - the mother of Doctor Doom - until Doctor Strange and Doom free her to ascend to heaven.Creating the Ghost Rider by bonding the demon Zarathos to Johnny Blaze. Mephisto plagues Blaze for years.Temporarily capturing the souls of Mister Fantastic (whose intelligence was also stolen by Mephisto), the Invisible Woman, and Franklin Richards due to a botched summoning by an exorcist.Creates Blackheart, a demonic entity that plagues many of Earth's heroes.Manipulated the sorcerer Master Pandemonium into gathering scattered fragments of his soul. When attempting to use magic to conceive children with her husband, the android Vision, the Scarlet Witch unknowingly summons two of the soul fragments which are born as her infant twins.Manipulating and then trying to destroy the Avenger Hawkeye when he enters Hell to try and save the soul of his deceased wife, Mockingbird. Hawkeye rescues Hellcat, but fails to see Mockingbird.Mephisto, as a demonic being of the highest order, is pure evil and possesses supernatural powers. Mephisto has the ability to take possession of living souls, but he only has claim over said souls if some form of pact is involved: he cannot indiscriminately abduct souls at will, (although is sometimes successful using subterfuge, technicalities, and deceit).Mephisto is capable of using his power for a variety of uses, including super strength, shape and size shifting, projecting illusions, manipulating memories, altering time, and is virtually invulnerable to non-metaphysical harm.Mephisto has also been shown to be energized by sources of intense evil in the human realm, such as the Dire Wraiths, which increases his power. Mephisto and his realm are symbiotically linked, and he is able to transform the structure at will. If Mephisto is destroyed, he will regenerate and reform there. In his own realm he has displayed the power to threaten entire galaxies. Show less «
