Which 'Godfather' character is the most popular?
Don Vito, of course.
It has been argued that Marlon Brando's portrayal of Vito Corleone was the role of his lifetime, the one he was "born to play." Similar matchups include George C. Scott as "Patton," Raymond Burr as "Perry Mason," and Robert Duvall as Gus in "Lonesome Dove." In cases like these, other actors who play the same parts in sequels or revivals are often rejected as being "off" or "wrong" or "not believable." It is interesting that Brando was cast as Corleone over the objections of Paramount Pictures executives, who preferred Ernest Borgnine, and even suggested Danny Thomas as the Don. Brando won an Academy Award for Best Actor for his work; being Brando, he refused to accept the Oscar.
I'm almost quite sure that it's going to be the main characters: Edward, Jacob, and Bella, of course. But if you're talking about the most swooned character, I'd have to say Edward. The most popular and made-fun of (only in the movie though) character: Bella. Then the hottest character. Gee I wonder who that could be. ;) Jacob.
Based on their endurance, Oscar winnings and quotability, 1972's The Godfather followed by 1974's The Godfather: Part II could be considered, arguably, the most famous and most popular movies from 1970 onward. The Star Wars franchise is another likely contender for the honor. However, more recent features have had tremendous success such as ET: The Extra-Terrestrial, Titanic, the Pirates of the Caribbean franchise and the Harry Potter franchise.
Spiderman can be considered, along with the Hulk as the face of Marvel comics similar to how Superman and Batman are the faces of DC. True there might be many other popular characters, but Spiderman is known world wide and is Marvel's most widely known and popular character (I am not saying the best, or the most popular in the US. he is the most widely known Marvel character)
