They are a team of incredible crimefighters who have banded together to oppose evil, combat crime and clean up the streets of Gotham City. They are…okay, they’re NOT Batman and Robin. They’re the Batwheels—an awesome group of sentient super-powered crimefighting vehicles defending Gotham City alongside Batman, Robin and Batgirl.
Duke Thomas is the daytime protector of Gotham City, and his metahuman light sensory powers make him unlike any of Batman's other crimefighting partners.
While Batman and most of his allies operate at night, crime in Gotham City is quite different in the daytime, and so requires a different kind of crimefighter. Enter Duke Thomas—a.k.a. the Signal, the brightly colored agent of the Bat who hits the streets when the sun is out and Batman is asleep in his cave.
