I may have got the wrong character, but are you referring to Major Major Major Major - the first instance being his rank, and the other three being his first, middle and last names?
Maybe not so well-known today, but the 1971 film Two Lane Blacktop, with James Taylor and Dennis Wilson, didn’t assign names to any character. Even lead characters were simply known as “The Driver,” “The Girl,” “The Mechanic,” and so on. The closest anybody gets to being given a name is “GTO,” but that’s only because he’s another driver, who as you might guess, drives a Pontiac GTO.
The Phantom of the Opera.
In 1984 McBain’s alter ego Evan Hunter published a novel called “Buddwing” about a man who wakes up in NYC with no memory. The last chapter has him remembering his whole life, and ends with something like “I know my name.” But the guy’s name is never actually given.
A very strange, wonderful read.
His name was Erik.
Missed it by 10 minutes. (I recently reread the novel, quite a bit darker then then show or movie)
My Bad. I thought “Erik” was an invention of screen and stage writers and was not in the original book.
Erik was probably not his birth name, we’re not told if he was even given a name by his mother.
One that would qualify from Phantom (the novel) is the Persian. He is a police chief that followed Erik from Persia to Paris.
John Doe from the TV series “John Doe” which starred a pre-Prison Break Dominic Purcell. “John Doe” was later used as an episode title on Prison Break.
True - nor, indeed, are there stated to be three of them.
The Haitian.
Or is he not well-known enough?
M’s name- explicitly mentioned several times in the Ian Fleming novels- is Sir Miles Messervy.
Interestingly, it’s implied in the recent version of Casino Royale that the Judi Dench “M” character also has a name that begins with M.
Q is also referred to in both the novels and the movie Dr. No as being “Major Boothroyd”, so I don’t think he counts either.
The Doom Guy is given a name in the novels- Flynn Taggart. I don’t know if these are considered “Canon” or not, though, so for all intents and purposes I guess he is nameless.
As specified in the OP it’s characters whose names are not very well known. The OP lists comic book guy, who does in fact have a name, but fairly obscure. Likewise, most people would know who Q and M are. Not many would know who Gyles Boothroyd or Miles Messervy are. They count.
I got the impression that The Comic Book Guy counted because they came up with a name for him something like 16 years after he first appeared in the show. M and Q were given names straight off the bat and I think they’re reasonably well known- not as well known as the “Q” and “M” monikers, but I don’t think they’re really obscure enough to qualify for the OP either, IMHO.
In the comic strip “Calvin & Hobbs” Calvin’s parents have no names.
I haven’t read it since high school… but wasn’t his name given as Henry Fleming?
Mr. Blonde’s name is Vic Vega, and Mr. White’s first name is Larry. I can’t remember if Orange is given a first name or not, but I wouldn’t be surprised if he reintroduces himself to the cop in the chair.
Mr Orange was Freddie. It was said a number of times.
The man in the brown macintosh? (James Joyce’ Ulysses.)
In Keeping up Appearances, Hyacinth and Richard Bucket are about the only characters with full names:
Daisy, Rose, Onslow, Violet, and Bruce have no last names.
Emmett has a last name, Hawksworth, that’s mentioned only once the whole series.
Emmett’s sister Liz, whose last name wouldn’t be Hawksworth because she’s married to an unseen husband working “abroad”, has no last name.
The Vicar and the Vicar’s wife have no names. Hyacinth’s father is merely Daddy.
Hyacinth and Richard’s son, Sheridan, has a roommate known only as Tarquin. Neither is ever seen.
