He’s dedicating his life to protecting a young girl who is like him while also caring for the ailing Professor X. The film certainly promises to be a much more mature story than any previous movie in the franchise, we haven’t seen much of our traditional comic book action in the first trailer.
Logan, being a man who doesn’t age normally, is still going, though his healing factor has apparently begun to fail him.
The details of Logan, which is still an awful title, are vague but we know that the film takes place in the future of the X-Men universe where most mutants have died out.
