It was fun to cause destruction. The Cryptid knows what he likes, and he has no issue with chaos at the expense of mortals. Humans have taken to calling the creature a harbinger, not that he minds. It's endearing, in a way. The small and insignificant beings provide him with a sense of satisfaction when he sees their terror, but he doesn't always want to scare them. Sometimes he wants to see what they know, what they feel.
He creeps behind the lone human who wanders carelessly through his Forest, unheard as they listen to sounds through their mechanical device. The rhythmic beats reach his keen ears. Is it that music thing so many humans speak of? Whatever it is, the Mothman doesn't really enjoy the high pitched sounds. The noise is so distracting in fact, that he missteps, crunching on a branch, and alerting the human to his presence. He makes no move to hide as the human turns and sees him there, in the shadow of a tree.
