Duke Thomas

Duke Thomas first appeared as a sharp-witted Gotham City teenager who crossed paths with Batman during the "Zero Year" storyline. He later became a key figure in the grassroots We Are Robin movement before joining Batman's inner circle as the Signal, a daytime protector of Gotham with emerging metahuman light-based abilities.

Duke Thomas burst onto the scene in Batman #30 in 2014, the creation of the legendary Scott Snyder and Greg Capullo, and he's been a meaningful presence in DC's Modern Age ever since. Over a dozen years and 84 catalog appearances — including two collector-recognized key issues — he's carved out real estate across Batman, Detective Comics, and Nightwing, the beating heart of Gotham's comics landscape. The company he keeps tells you everything: Robin, Batgirl, Cassandra Cain, Alfred Pennyworth, and The Signal all share his pages, placing him firmly inside Gotham's rich, layered mythology. If you're tracing the modern evolution of the Batman corner of the DC Universe, Duke Thomas is a name you'll keep encountering — and one well worth following.
