The Club of Heroes, also, but incorrectly known as the Batmen of All Nations, was a pairing of vigilantes led by the famous Batman.
Millionaire John Mayhew took together a team of vigilantes led by the Batman, with the majority appearing to have gimmicks similar to the caped crusader. Mayhew ended up building several tools and gadgets for the Club, but after Batman left the Club broke down in less than an hour. Years later the Club had a reunion, in which Mayhew ended up siding with the Black Glove and attempting to kill some members. Batman later consolidated the former members of the Club into Batman Incorporated.
