X-23 aka Laura aka Talon (VERY RARELY) is a clone of Wolverine.
The Weapon-X Project wanted to clone Wolverine, but their sample’s Y chromosone was too damaged to allow it, instead they copied the X chromosone resulting in a Female clone.
X-23 was raised in a lab and trained to be an assassin, the use of trigger scents on her targets would make her kill them in a bezerker rage.
She eventually escaped, killing everyone who made her along the way, and headed to New York where she became a prostitute who specialised in cutting people up.
Then she joined the X-Acadamy, and eventually became a part of X-Force with her “Big Brother” Wolverine.
Her powers are a variant of Wolverines, she has 2 claws in her hand’s for offence, and a defesive claw in each foot. Her claws are coated in Adamantium but her skeleton is not. She has a healing factor and enhanced senses.
Besides her “Brother” Wolverine, she has a nephew who is about 10 years older than her, Daken.
She actually first appeared in the X-Men evolution cartoon series.
