AAs the mayor is addressing the Festival crowd, Mothman flies overhead, and pandemonium breaks out. A woman is knocked from her seat on the Ferris wheel, and the police start firing at Mothman. The mayor dives for cover, and Frank Waverly takes the podium, blaming the whole town for covering up his little brother's death. Just as he calls for blood to be spilled in order for the town to be forgiven, Mothman kills him. Katharine, Derek, and Casey drive up in their pickup. Derek begins firing on Mothman while Katharine runs around yelling, 'No...no...go home', and Casey takes refuge in a policecar. The mayor picks up a gun and begins shooting at Mothman, but it attacks and kills him. Casey barrels the policecar into Mothman, but Mothman breaks the windshield and kills Casey. Katharine fires a rifle at Mothman and blows up the car. Mothman still keeps coming. Remembering how he squealed when she jabbed him with the bone knife in Frank's basement, Katharine goes after Mothman with the knife. She succeeds in stabbing him in the chest, after which he disintegrates, releasing a cloud of black moths with a big red spot on their wings. In the final scene, Katharine visits Derek in the hospital. She kisses him...twice. After the second kiss, her eyes begin to glow red. Derek backs up against the headboard, yelling, 'Stay away from me!' Black moths start flying all around him.
AAlthough it's suggested that the area around Point Pleasant has long been considered by Native Americans to be inhabited by an evil spirit, the origin of Mothman in this film is credited to Chief Cornstalk, an 18th century Shawnee Indian who opposed white settlements along the Ohio River. According to the film, he was tortured by the white men. Before he died, however, he called up the evil spirit and transformed into the Mothman. The men cut him up and placed his body parts in a coffin lined with mirrors, making it so that Mothman can only cross over into the living world through reflective surfaces.
