The Sunset Gang were a group of costumed criminals that worked under the instructions of the Outsider, who was only known to them as "Mr. O". On their first caper, they tried to commit some crimes in New York City, but they were challenged by Man-Bat, although he failed to capture them.
The Sunset Gang returned to face the Man-Bat once again, but this time they were finally defeated, forcing the Outsider to confront Man-Bat by himself. After the Outsider's defeat, the Sunset Gang was disbanded.
