The MC has the physical capabilities of that of an upgraded vampire (beast) similarly to that of Lucien Castle and Marcel Gerard.
The MC has the psychic capabilities of that of an Immortal such Silas.
The MC can now do magic by siphoning his very being considering that he is now a supernatural creature born from black magic and he doesn't have magic but his body it self is one big embodiment of black magic. Which causes him to have his black eyed black vein appearance in his true face and a slight change in personality. He doesn't run out of black magic but he will begin to desiccate when overused.
Like Immortals and vampires he is still reliant on blood. He is more like an Immortal, he needs blood to survive but has no bloodlust like a vampire.
He is a unique being all to himself. A being that wasn't supposed to be.
