Which is the greatest of the Universal monsters?

The Invisible Man

He is the scariest and the most interesting, because he is just a man. There is still the science fiction element to him though, so that is what makes him more interesting than the Phantom of the Opera.

Dracula.

Define greatest. The 1999 version of the Mummy is probably the most powerful.

Dracula remains my favorite; he was the only one who genuinely scared me as a kid, and I still find him scary in a way I don’t with the others. The Frankenstein Monster is a great character, and Frankenstein and Bride are fantastic movies, but I never found the Monster scary, for whatever reason.

Also, Dracula the ’31 movie has all these nuances that for me make the character—and the movie. Like this line:It always gets discussed like it’s a threat, but it’s more sad than scary: Dracula has experienced that far worse thing than death, and for him death would be a glorious release.

But it’s a throwaway, and that’s what makes it: We don’t get any more attempts to sympathize with Dracula, who is (after all) going around killing people, but for a moment we see into his character. It’s smarter character writing than for all the modern intended-to-be-sympathetic Draculas, Frank Langella and Gary Oldman and Claes Bang, I’ll tell ya that.

Claude Rains’s Invisible Man is high on my list too, as is Boris Karloff’s Mummy, but ultimately my favorite remains the funny-talkin’ Transylvanian.

I'm partial to The Invisible Man

That's like asking to pick your favorite child.

Did Stephen King create any of the Universal Monsters listed on this poll ? 

For me, it is Bride of Frankenstein, Whale's Dark Carnival of mad scientists, miniature homunculi, wedding bells signaling the arrival of an electrically charged bride right off the laboratory table and her disappointed would-be husband blowing everyone to Hell in a fatal fit of rejection. 

The delicious insanity of it all!
