Marvel quietly revealed a huge Doctor Strange retcon that changes a key part of his lore. Doctor Strange may not be as physically strong as Thor or as world-famous as Spider-Man, but he's certainly one of Marvel's most powerful and essential heroes. Strange has also remained largely unchanged in the comics when compared to his first debut.
Marvel Comics' Doctor Strange has grown to be a more charismatic and less serious hero than he used to be during his first adventures. Like his MCU counterpart, comic-book Strange has learned to be humble, but he has amassed an even bigger well of magical knowledge after years and years of battles. All along, however, he has been accompanied by another character, and he's only realizing it now.
