So, let us create a list of the archtypes featured within the Pulp genre (and its sub genres) so as to help us (and by us I actually mean me, I'm thinking of running a pulp game.)
So, let us go:
Costumed/gimmick Detectives, e.g the spider, the Spirit, Grey Shirt, The Sandman
Costumed Adventurers: e.g The Phantom, The Terror
Adventurers: e.g Indiana Jones, the gang from The Mummy.
More than mere men: e.g Doc Savage
Dames, Damsels, Love interests: e.g The woman in Red
Jungle Kings: Tarzan, The Phantom, Jill of the Jungle
Ethnic stereotype characters: e.g Fu Man Chu, almost every minority.
Better than average guys: Doc Savage's league, the gang from the mummy.
I've got to be missing some archtypes...
