Sumo

A Bronze Age creation stepping onto the page in 1978's Wonder Woman #241 — brought to life by Gerry Conway and Joe Staton — Sumo is a compact but intriguing corner of the DC universe with roots in one of comics' most storied titles. Their presence extends into Young All-Stars, where they share adventures with a colorful wartime cast including Baron Blitzkrieg, Neptune Perkins, and Dan the Dyna-Mite. With only a handful of catalogued appearances, Sumo is the kind of deep-cut discovery that rewards the dedicated collector hunting for hidden gems in DC's Bronze Age landscape.
