Mark Scheffer

Mark Scheffer, known as Shrapnel, is a DC villain whose body transforms into jagged, razor-sharp metal fragments, making him a dangerous physical threat. He has clashed with the Doom Patrol and various other DC heroes across multiple series.

Bursting onto the scene in 1988's Doom Patrol #7 courtesy of Paul Kupperberg and Erik Larsen, Mark Scheffer is a Copper Age DC creation with a lean but intriguing footprint in the publisher's universe. Over a span stretching into 2012, he's turned up in corners as varied as The All New Atom and the Justice League Wedding Special, sharing pages with heavy hitters like Green Lantern, Firestorm, and The Flash — the kind of company that signals a character woven into DC's broader tapestry rather than confined to a single corner of it. With only seven catalog appearances, he's a rare find for the dedicated completist, the sort of deep-cut name that rewards the fan who loves hunting through the margins of DC history.
