Doc Savage/YMMV

• Marty Stu: Doc has some characteristics of this, being a perfect physical specimen, incredibly brilliant, unbelievably badass and so on, and so forth. But he's hopelessly inept with women.
• Fridge Logic: Didn't Adolf Hitler in disguise hit on you at the start of this adventure?
• Older Than They Think: Doc's Arctic "Fortress Of Solitude". While it may appear to be a rip-off of Superman's, it is lifted, name and location included, from the very first Doc Savage story, published in 1933. Supes first got his retreat hang-out in 1938, it was located in a mountain cave outside of Metropolis, and it was called his "Secret Citadel". The Arctic version and the name "Fortress of Solitude" wasn't used in the Superman stories until 1958.
• Values Dissonance: The "Crime College", where captured crooks are given brain surgery to wipe out criminal impulses and retrained into productive law-abiding citizens, leaves a bad taste in the mouths of many modern readers. Some later authors have even suggested that Doc was lobotomising the crooks.
