David Hiles

A brief but collector-noted presence in Image Comics' Modern Age, David Hiles debuted in Savage Dragon #102 in 2002 under the pen of Erik Larsen — and that first appearance carries enough weight to be flagged as a key issue. His handful of appearances span some genuinely landmark Image territory, popping up across Savage Dragon, Invincible, and G.I. Joe, which means he's shared pages with heavyweights like Invincible, Omni-Man, and the Grayson family. Rare doesn't always mean obscure — sometimes it means every appearance counts.
