Mephisto is a dimensional being of immense power. He is a mysterious and constant threat to all humans, biding his time and striking only when it suits him. From within the fiery dimension, he sends forth cunning schemes and wicked deals to ensnare the unwary in contracts to secure their souls.
His ability to manipulate humans has allowed him to cut deals with the likes of Norman Osborn and Peter Parker when they were at their lowest. These deals always benefit him at the expense of the other party. Thanks to his ability to sense the future, his defeats are merely acceptable outcomes.
