Blackheart

Blackheart is a demonic entity from Marvel comics and the son of Mephisto, as such he is a creature of immense supernatural power and evil that is comparable to an arch-demon in status: although not quite as powerful as his father, Blackheart is more than a match for any of Earth's heroes and has faced many of Marvel's greatest heroes in battle.

Blackheart is also a major antagonist in the Ghost Rider live action movie.
