Matches Malone is a character appearing in American comic books related to DC Comics. He was originally a Gotham gang boss whom Batman attempted to recruit to help take down Ra's al Ghul, but he was accidentally killed by a ricocheting bullet that was meant for Batman who impersonated the man to use his underworld contacts and to fool Ra's.^[11]

Post-Crisis, Malone was a small-time arsonist with his brother Carver and who came to Gotham City early on in Batman's career, attracting Batman's attention when Carver was apparently murdered. After discovering that Malone had died as well, Batman adopted his identity as his own as nobody else knew of the death. Years later, Batman learned that Carver had committed suicide due to his guilt over a fire that he and Malone had started that resulted in the death of a homeless man.

After operating underground for years by committing low-end robberies, Malone returned to Gotham after hearing reports of his activities, only to be shot by Scarface for his betrayal, surviving long enough to simply confess his role in events to Batman and Nightwing before dying. His last request was that Batman bury him next to his brother and avenge his death. Batman subsequently destroyed Scarface in 'revenge' for Malone's death. Talking with Nightwing, Batman observed that he would continue using Malone's identity as he had come to recognize that Malone was not an evil man, but had done some bad things that he never had the chance to make up for, the Dark Knight regarding his use of Malone's name as a chance to give him absolution.

The "Matches Malone" identity indirectly caused the events of Batman: War Games, when Stephanie Brown attempted to implement an old plan of Batman's that would allow the latter to take control of Gotham's criminal organizations, hoping this would impress Batman enough to convince to take Stephanie back as Robin. Stephanie was unaware that the "agent" who was meant to take control of the meeting was Batman acting as Malone, resulting in tensions between the crime families flaring up and most of them being killed in the subsequent stand-off, leading into the subsequent gang wars and Stephanie's own apparent death.
