Robert Reynolds

Robert Reynolds is an ordinary man who broke into a laboratory and ingested an experimental serum, granting him the power of a million exploding suns. As the Sentry, he became one of Marvel's most powerful heroes — yet his fractured psyche proved as formidable a challenge as any villain.

Few Modern Age debuts have landed with quite the mythology-drenched weight of Robert Reynolds, who first stepped into Marvel's spotlight in 2000 courtesy of the visionary team of Paul Jenkins and Jae Lee. Over a remarkable 26-year publishing span, he's accumulated 211 catalog appearances and a staggering 16 key issues — a collector's trail that speaks to a character who genuinely matters. His world is populated by Marvel's heaviest hitters; sharing pages with Spider-Man, Wolverine, Ms. Marvel, and Captain America, and appearing most prominently across New Avengers, Dark Avengers, and The Mighty Avengers, Reynolds sits at the turbulent heart of the Modern Marvel universe. If you're building a serious Modern Age collection, following Robert Reynolds is anything but optional.
