Powers: With his Darksoul, Mikal Drakonmegas possessed a high level of magical power. He could shoot energy blasts from his hands and had heightened strength. He also stole a gun of his father's creation from a demon working for him. The gun could not fire unless willed so by his father (or him) It's likely he has many more powers than he has shown, but just isn't experienced enough to use them yet. Without the Darksoul, Mikal is naturally very charismatic and has a decent knowledge of the basics of the occult, though he was very surprised when he found out much of it is true.
Weaknesses: Hellfire's power depended entirely on his possession of the Darksoul. If it's taken from him, he is returned to his state as Mikal Drakonmegas.
