Jack O’Neill

Few characters arrive with quite such an eclectic calling card as Jack O'Neill, who made his comic debut in a 2003 Free Comic Book Day edition from Avatar Press — sharing space with the likes of Teal'c, Samantha Carter, and Daniel Jackson in what was clearly a banner moment for Stargate fans hungry for four-color adventures. A Modern Age creation brought to the page by Jeremy Rock, O'Neill's catalog footprint spans titles like Stargate SG-1: Fall of Rome and Stargate SG-1: Aris Boch, painting a picture of a character at the center of some genuinely ambitious licensed comics storytelling. With 11 appearances across Avatar's mid-2000s Stargate line, he's a focused but rewarding find for collectors who love seeing beloved genre properties get the serious comic treatment — and that FCBD debut issue alone makes him a fun piece of early 2000s licensing history worth tracking down.
