The Owl. Nick Terry is a special investigator for the police department of "Yorktown," a large city in America's Midwest. Unfortunately, he finds that the police can do only so much, so he takes the law into his own hands and dresses up as the costumed vigilante the Owl to fight for freedom unfettered by regulations. He is assisted by his girlfriend Belle Wayne, a gossip columnist who is also his sidekick Owl Girl. The Owl has no superpowers, but he's got an array of equipment, including an Owlmobile which can fly, doubles as a roadster, and is armed with "Owl-bombs" and a darkness-casting blacklight ray; and robot Owlos, controlled ultrasonically, which can see through the blacklight ray, can track like bloodhounds and can divebomb enemies. The Owl's cape also doubles as a parachute.
