here is the link: http://marvel.wikia.com/Laura_Kinney_(Earth-616) she is Wolverine's female clone created by the Weapon X program as a killer. She has Wolverine's claws except she has only two on her hand and one on her foot. The program created a trigger which, when put on someone, will make her go into a berserker rage and kill that one person. She is not in control so she could kill her own mother if the trigger was on her. She escaped the program and eventually became an X-man and later joined X-force which she left. This is just a quick summary, more information is in the link.
