Cecilia Reyes is a trauma surgeon who is also a mutant with the special ability to create a forcefield around her body. Unlike most of the X-Men, Celia Reyes isn't interested in becoming a superhero and only wants a normal life. It isn't clear how this character will fit into The Wolverine story line, which takes place in Japan and features Hugh Jackman's character searching for more information on his background.
James Mangold is directing The Wolverine from a script by Christopher McQuarrie. Star Hugh Jackman made an appearance at San Diego Comic-Con a few weeks ago, where he revealed that The Wolverine villain will be the Silver Samurai.
