D'Bo—known as Devo the Cursed in the original Japanese version, though the Viz manga translation calls him Soul Sacrifice—is a hired assassin working under Dio's orders to eliminate the main characters.
What makes Devo memorable is his twisted Stand ability, Ebony Devil, which grows stronger the angrier and more hateful he becomes. Rather than avoid damage, he actually courts it, deliberately letting himself get hurt to fuel his rage and power up his Stand. This self-destructive strategy has left him covered in scars across his entire body—a walking testament to his relentless pursuit of anger as a weapon.
