The Earthworm

Burrowing into the DC Universe via one of comics' most beloved reference works, The Earthworm made their debut in Who's Who: The Definitive Directory of the DC Universe #7 in 1985 — meaning this character was introduced to fans as a defined piece of DC lore right from the start, courtesy of Bronze Age architect Len Wein. With appearances in Guy Gardner: Warrior alongside heavy-hitters like Guy Gardner himself, Green Lantern, Hawkman, and Ted Grant, The Earthworm keeps genuinely formidable company in the DC cosmos. Rare in the catalog with only three recorded appearances — one of them collector-significant — this is precisely the kind of deep-cut character that makes DC's universe feel so wonderfully vast and layered, a hidden gem waiting to be rediscovered by the dedicated fan willing to dig a little deeper.
