Colonel Darnell

Colonel Darnell is a U.S. military commander who appeared from the very first Wonder Woman stories, serving as the superior officer to Steve Trevor and, by extension, Diana Prince in her secret-identity role as his military secretary.

Few supporting characters can claim roots as deep as Colonel Darnell's — a fixture of DC's Golden Age who stepped onto the page in the landmark Sensation Comics #1 (1942), courtesy of the legendary creative team of William Marston and Harry Peter. As a military authority figure woven into the fabric of early Wonder Woman stories, he's been part of the Amazon's world from the very beginning, sharing those classic pages with Wonder Woman herself, Steve Trevor, Etta Candy, and Diana Prince. With four key-issue appearances to his name and a presence that stretches across an remarkable 84-year publishing span — from the Golden Age all the way to 2026 — Colonel Darnell is a testament to how even a supporting player, when introduced at the right moment in comics history, can quietly endure through the ages.
