While many of its members come from various avenues within the DC Universe (or DC Multiverse, even), the Intergang’s base of operations has typically been in Metropolis, which means that the group has a special place in the rogue’s gallery of the city’s resident Krytopian protector: Superman. The Man of Steel has faced off against the villains (individually or collectively) countless times, including one instance when he was not in costume, but as Clark Kent. He and fellow Daily Planet reporter Cat Grant collaborated on an exposé that brought the syndicate to its knees… for some time at least.
The Intergang has also expanded its range to Batman’s turf, Gotham City, where they were not forced to contend with a member of the Batfamily (Kate Kane, a.k.a. Batwoman) and GCPD detective Renee Montoya, who had then taken up the mantel of The Question by then. Yet, perhaps the Intergang’s most famous and important failure is one of its first when they attempted to make an innocent teenage boy their minion.
