Jonas S. Jeffries

Stepping onto the page in 1988 during the height of the Copper Age's military comics boom, Jonas S. Jeffries is a G.I. Joe universe figure who has quietly persisted across an impressive 34-year span — a testament to the deep bench of characters Larry Hama and Ron Wagner built into that legendary franchise. He shares his adventures with heavyweights like Duke, Wild Bill, and Conrad S. Hauser, keeping some of the most recognizable names in the Real American Hero roster as company. His appearances stretch from the original Marvel run through IDW's dedicated stewardship of the property, surfacing in the classic trades that collectors prize. A character like this rewards the devoted fan who loves digging beneath the headline names to discover the full, richly populated world Hama so carefully constructed.
