Blake's body began to transform, his muscles bulging and skin darkening to a deep crimson. His fingers elongated into wicked claws, and horns sprouted from his forehead. The air around him shimmered with dark energy, and the ground beneath his feet began to crack and smolder.
The familiar's form flickered uncertainly. "This power... it is not of your world," it said, its voice a mix of awe and concern.
Blake let out a roar that shook the place, his demonic form now fully manifested. With inhuman speed, he lunged at the familiar, his claws tearing through its elemental body. The familiar reeled back, its form destabilizing.
"Impossible!" it cried out, desperately trying to reform itself.
But Blake was relentless. He moved like a dark blur, striking again and again. Each blow seemed to weaken the familiar's hold on its physical form. The elemental being lashed out with fire and lightning, but Blake's demonic hide seemed impervious to the attacks.
