X-23, also known as Laura and played by Dafne Keen in Logan, is a female clone of Wolverine who was then put through the same kind of experimentation and training that Logan underwent at the Weapon X program. That included having her bones coated in adamantium and being treated like a weapon rather than a person.
The new promotional video gives a glimpse into Laura's life in the facility where she was born, the procedures that were forced on her, and the emotional and physical scars they left her with.
Logan takes place in the year 2029, where mutant births have become extremely rare. The defenders of mutant kind, the X-Men, are long gone, and the only remains of them are an old and struggling Charles Xavier and a weary Logan. Logan's vaunted healing factor has slowed, and at times doesn't seem to work at all. When a young mutant needs his help, Logan has to unsheathe his claws once more. His job isn't over yet.
Logan stars Hugh Jackman (Logan), Boyd Holbrook (Donald Pierce), Patrick Stewart (Charles Xavier), Dafne Keen (Laura Kinney/X-23), Doris Morgado (Maria), Stephen Merchant (Caliban), Elizabeth Rodriguez (Gabriela), and Richard E. Grant (Dr. Zander Rice). James Mangold is directing and helped on the screenplay along with Scott Frank and Michael Green.
Logan hits theaters on March 3, 2017.
