The Clock (my avatar), Shock Gibson and Cat-Man are three heroes I like. Sheena, Queen of the Jungle, but her character isn't public domain although her comics are. Doctor Nemesis, a crime / hero character; some of his stories venture into horror. The Black Phantom (a woman) and Redmask (a man), two Western heroes who wear masks. Spy Smasher, a aviator type of hero. Here's an obscure hero no one but me likes - The Zebra (from Green Hornet Comics). Those are some of my favorites. It's kind of hard to pick stories since I'm a fan and I'll tell you "all of them", but you may not like what I do. Hope this helps!
