David Cain

David Cain is one of the world's most deadly assassins, introduced in DC Comics as the man who trained and raised Cassandra Cain, shaping her from birth into a living weapon through brutal conditioning rather than conventional childhood.

A shadowy figure who slipped into the DC Universe with the very first issue of Batgirl in 2000, David Cain has haunted the Modern Age as one of the darker presences orbiting Gotham's world — the kind of character whose appearances in Batgirl, Detective Comics, and Batman signal that something genuinely dangerous is unfolding. Created by Scott Peterson, Kelley Puckett, and Damion Scott, he shares pages with Cassandra Cain, Bruce Wayne, Batman, and Oracle, placing him squarely at the intersection of Gotham's most compelling corners. Over 25 years his appearances have remained lean and purposeful — this is not a character who overstays his welcome, which only sharpens the sense that every panel he occupies matters.
