Avenger Third Grade. A unique status crafted for the first (and ultimately, only) graduating class in Avengers Academy #39.
Laura was originally believed to be a female clone of Wolverine, created by "twinning" his X-chromosome and surrogately carried to term by Sarah Kinney. Death of Wolverine: The Adamantium Agenda #1-4 confirmed Laura was instead a test tube baby, artificially engineered from the genes of Logan and Sarah Kinney, making them both her biological parents.
There are currently two versions of Laura active, one called Wolverine with the X-Terminators and one called Talon with the X-Men. After infiltrating the Vault in X-Men (5th series) #19, Laura was believed dead and resurrected on Krakoa. In X-Men (6th series) #16, however, "Old Lady Laura" was found alive in the Vault and brought back. The older Laura is Talon while the younger one, Wolverine, was inadvertently given a full Adamantium skeleton by Proteus during resurrection.
