Photon

Bursting onto the scene in the landmark 1998 Avengers #1 — a collector-recognized key issue brought to life by the legendary George Pérez and Tom Brevoort — Photon is a Modern Age Marvel creation with genuine staying power. With nearly three decades of publication history stretching from 1998 all the way to 2026, this is a character who has proven their enduring place in Marvel's universe across titles like Avengers, Avengers Infinity, and Avengers Assemble. The company Photon keeps is nothing short of elite — sharing pages with Captain America, Thor, Iron Man, and Steve Rogers puts this character right at the heart of Marvel's mightiest adventures. Three key-issue appearances signal that serious collectors have taken notice, making Photon well worth tracking down for anyone who loves diving deep into the rich, ongoing tapestry of Avengers history.
