The scars on Logan's back

Taking cues from the "Logan" trailer, it is evident that the upcoming film is darker than its predecessors and shows Logan and Professor X as ageing mutants whose powers have begun to dwindle. One striking thing about Logan's appearance is that he is sporting some massive battle scars on his back.

In an interview with Empire, director James Mangold reveals that the scars on Logan's back are manifestations of the effects of his advancing age on his healing powers. He explains that while Logan can still heal, the skin that regenerates is no longer "baby-soft."

"We imagined that it may have when he was younger, but with age, he's getting older and ailing. Perhaps his healing factor no longer produces baby-soft skin. So we imagined he heals quickly, still, but it leaves a scar," Mangold says.

Who's his new companion?

Aside from Professor X, Logan is joined by a young companion in the new movie. The mysterious girl has been identified as a mutant called X-23, who has Logan's DNA and effectively also some of his powers.

In the trailer, Professor X tells Logan that X-23 is "very much like you," which makes it safe to say that she might also have healing powers and that she might also age slower than the average human being.

X-23 is known as Laura Kinney in the comic books, and is the 23rd attempt by Essex Corp to make a clone of Wolverine. According to Comicbook, she is designed to be the perfect assassin, but due to the cruel treatment from the scientists that created her she takes them out instead. Now that she's free from the tortures in the facility, she sets out to find Wolverine, Professor X and the Xavier Institute.

"Logan" release date is on March 3, 2017.
