Batman Family#19(1978)

Bruce Wayne travels across the snowy mountains with an Ambassador and his team. Their travel comes to an end when a bridge they just crossed is blown to pieces and as they come out of the vehicle, they are attacked by unknown snipers. Bruce quickly changes into Batman and follows the source of the attack, which turns out to be natives of the mountains. An elder woman of their tribe explains to Batman that they were not aiming to attack their group, but instead, they looked to eliminate the threat of an ancient white bat, which is said to prey on the living. Batman then returns to the vehicle and he saves the Ambassador and his assistant from a certain death from a grenade that somebody tossed at them. After noticing the pattern of the attacks and learning that most of the Ambassador's crew has left the vehicle, Batman deduces that someone from the same crew is out to kill the Ambassador. Batman is finally confronted by the driver of the vehicle, who is the man behind the murder attempts on the Ambassador. He explains how he killed the other members of the crew using a special device that gave them marks in their necks, making it look as if they were murdered by a vampire bat. The man tries to kill the Ambassador, but Batman prevents another murder. The criminal then tries to escape on a helicopter, but some unknown force causes him to crash the vehicle to the ground. As Batman examines the crash site, he feels the presence of a white bat, flying above him.
