Dexter Cortex

Dexter Cortex is a villain from the Big Bang Comics universe, a shared setting that lovingly recreates the feel of Silver Age superhero comics. He has crossed paths with Big Bang heroes such as Ultiman, the Knight Watchman, and Thunder Girl.

Dexter Cortex made his entrance in the pages of Supreme #24 in 1995 — a Copper/Modern Age debut from Image Comics — before finding his true home in the beloved Big Bang Comics universe, that affectionate celebration of classic superhero storytelling. Over a surprisingly enduring stretch running all the way to 2022, he's shared adventures with luminaries like Ultiman, The Knight Watchman, and Thunder Girl, placing him squarely in some of the most nostalgia-charged corners of independent comics. With eleven catalogued appearances across Big Bang Comics, Big Bang Adventures, and Supreme, Cortex is a niche discovery waiting to reward the curious collector who loves digging beneath the surface of the mainstream.
