Fan Casting Captain Boomerang in Tim Miller's Batman: Assault on Arkham

(Digger Harkness)

Role added by @michaelcosby on August 11, 2026

Human / Humanoid

Character Description

The crass Australian wildcard. Harkness is a racist, sexist, perpetually grinning degenerate—universally despised by the Squad, constantly scrapping with Deadshot for leadership, and ultimately left behind in the chaos. He's comic relief by way of utter moral bankruptcy.
