The character was created in 1941 by Ben Thompson, who also drew the first comic book adventures of Ka-Zar the Great and Citizen V for Timely, as well as the Masked Marvel for Centaur Publications and Dr.

[3] More than thirty years later, Marvel launched The Invaders in 1975, an intentionally nostalgic comic featuring star characters from the Golden Age — Captain America, Bucky Barnes, the Human Torch and the Sub-Mariner — in World War II-era adventures.

Writer and editor Roy Thomas wanted to expand the franchise, so he created the Liberty Legion with a group of second-string Golden Age heroes, including the Blue Diamond, along with Miss America, the Whizzer, the Patriot, the Thin Man, Red Raven and Jack Frost.

Thomas said that there were plans for a Liberty Legion series, but by that point, the sales figures on the Invaders comic were dropping, and Marvel decided against launching a spin-off.

[6] After he is rescued by a British ship, he finds that the shards of the diamond gave him diamond-hard skin, giving him superhuman strength and nigh-invulnerability.
