The bite was vicious enough to merit a pained cry from Peter as he pulled back, trying to lift his arm to bat away the thing that was already jumping away from him. His arm refused to respond. Peter threw up a telekinetic barrier, keeping all the other beings at bay for an instant as he looked down at his arm. There was an odd orange glow around the puncture wounds, and the venom was seeping through his arm, making the veins glow lightly. The barrier broke as Peter used the ability to tourniquet his arm, preventing the poison from flowing into the rest of his body.
He looked at the large demon that he'd frozen to the ground. It was breaking through the ice. With a flash of rage at having been poisoned, Peter threw all the force he could muster at the creature's throat, the power knife-thin, severing the demon's head from its shoulders. Another quick, sharp cut of telekinesis, and Peter was weilding one of the massive claws in his hand, lashing out with it at the other demons. He was angry, he was hurt, and he'd be damned if he was going to let some undead bitch get the better of him.
