I've been reading Roy Crane's adventure strip Wash Tubbs recently, and it began as the adventures of a perpetually horny manlet Wash who wants to travel the world and fuck women. In one of his adventures he meets a sidekick adventurer named Captain Easy and he ends up being the muscle who does all the heavy lifting and in short order Wash becomes the sidekick. Eventually the Sunday's were exclusively about Captain Easy while the dailies were their adventures together.
