Yep, I was reading somewhere, Hercules now-a-days is often referred to as
Classical Superman 
Okay, ya'll managed to drag me out of lurk for this one. I haven't heard it put that way, but I have heard Superman referred to as a modern Hercules. Seems like that reference is one of the books I have on either DC Comics or Superman.
And to add to the list, I haven't seen either of these rather obvious ones yet:
Shield
Cape
Of course, Cape might be a little TOO obvious if the point is to keep who they're talking about hidden but I kind of like Shield myself.
