During the fight the Madmen gained control of Beetle's gun but could not figure out how to use it. The public did not know what powers the gun possessed; the Madmen took advantage of this to enhance their crimes. Blue Beetle eventually regained his gun (only containing a strobe light) and apprehended the Madmen. After serving their sentences, the Madmen retired until they were paid to attack Kord Industries by Doctor Alchemy. Once again they were jailed.
The Madmen became a more persistent annoyance to Blue Beetle. They returned to face him time and again only to be defeated after each attempt. Fleeter, however, was not discouraged. Taking a job at Georgetown University to steal drugs, he was involved in an accident that gave him the power to mentally control anyone he touched. He used this power to create an army of Madmen, but was defeated by Hawk and Dove and sent to Belle Reve prison.
Sometime later, Fleeter was incarcerated at Arkham Asylum and was a victim of the Joker's venom. He caused problems in Gotham City until he was captured by the Beetle and Robin. When next seen, the Madmen were invited to join the Society. Their first assignment was to attack Blue Beetle. Though they failed, their actions led to his death. Next, they were given guard duty and were attacked by the Secret Six. During the Battle of Metropolis the Madmen were gunned down by Wild Dog, Crimson Avenger III, and Vigilante.
