"Titular"
The general noun phrase "title character" term is an alternative phrasing to the seemingly more formal "titular character." The term can also be replaced using the adjective "titular" with a descriptive noun or phrase. For example, the title character of Dracula can be referred to as that book's "titular vampire", the title character of Hamlet is the "titular prince of Denmark", and the title character of The Wonderful Wizard of Oz is the "titular wizard."
