The owner and barman of the Clark’s Bar & Grill is himself a man of mystery. At first sight he looks like a older man who enjoys his job as the barman of a local where superheroes (and villians) hang around, from several different teams, from WildCATS to Mercs and even Stormwatch.
Surprisely fights in Clark’s place doesn’t happen often. Some people as Deathtrap said than criminals respected him because it is the only good bar in New York. But others, as Hellstrike can confirm, known than Clark himself can manage any super powered problem it could arise.
Maybe his resemblance with certain strange visitor of another universe isn’t a coincidence.
