Gus

A small but memorable piece of Marvel's mid-'90s reinvention, Gus made his entrance in the landmark Captain America #1 of 1996 — a bold relaunch brought to life by the superstar team of Rob Liefeld and Jeph Loeb. Over a publishing span that stretches all the way to 2019, this supporting player has kept genuinely prestigious company, sharing pages with the likes of Steve Rogers, Rikki Barnes, and Master Man across the Captain America series and the sweeping Heroes Reborn Omnibus. Four catalog appearances may be a modest tally, but rubbing shoulders with icons of the shield for over two decades gives Gus a quiet staying power that any devoted Marvel completist will want to track down.
