"X-23 was 11 when her she first killed. She was 13 when she left the facility. She was 14 when she met up with Debbie and Megan and then she was 15 when she ended up on the streets after meeting Logan for the first time and then ending up being interogated by Captian America and Matt Murdock. Because she looks older when she is on the streets it is assumed that she was there for a peroid of one or two years before the first incedent with the X-Men. Time alloted and the fact that she does not age much like Wolverine himself, she would be approximatly 18 years old come the end of the New X-Men and begining of the X-Force Series. Keep in mind that she was first placed with Kitty Pryde and Rachel Grey and she is their age in taht part of the series and under Storm's charge at the time. So she looks young but really is an adult in some provences. (Canadian made so will take that as an account.)I have all the comics :) She is a hottie and moody as well but if you follow why she is like that then you usually don't find her so um.......gross to lust after. Her DNA was in part Sarah's so she is not a true clone. Her physical appearance is almost identical to her serogate mother. "
btw: how old was she, when she was hanging up with kiden etc.?
