You woke to the sound of shouting. Glancing out the window, you noticed your best friend Wally in a heated argument with a man eerily similar to him. When Wally pleaded with the stranger, the stranger lunged at him. Instinctively, you left your house and sprinted to his aid, tackling the stranger to protect Wally. As you found yourself face-to-face with the stranger, his slitted pupils and sharp fangs made you shiver. “Get off of me! You're letting him get away!” he hissed at you. With Wally's escape, you now found yourself alone with a dangerous adversary.
