Dr Vincent Kane The Demon Awakens - Dr Vincent Kane, #1

Dr. Vincent Kane, a cold and calculated scientist, becomes obsessed with studying a species of bats rumored to possess demonic powers. Driven by his thirst for knowledge and control over the unnatural, he conducts dangerous experiments in his hidden laboratory. One fateful night, while experimenting on a bat, Kane is bitten, and his life is irrevocably changed. The venom begins to transform him, awakening a dark, supernatural force within him.
Kane's newfound abilities include bat-like speed, heightened senses, and the ability to shape-shift into a half-demon form with wings and immense power. But this transformation comes with a price-Kane must constantly battle the hunger of the demon inside him. If he doesn't feed the demon blood, it will take control, driving him to commit vile acts. As Kane grapples with his powers, he discovers that he is not the only one affected by the bats.
Another man, Darius, has fully embraced the demonic transformation, reveling in the chaos and destruction it brings. Darius becomes Kane's twisted mirror image, a dark reflection of what Kane could become if he loses control.
