3) X-23 (Laura Kinney)
Like a small handful of characters before her, Laura Kinney AKA X-23 did not originate in the comics but on TV – specifically, 2003 animated series X-Men: Evolution. The clone daughter of Wolverine, Laura proved to be such a hit that she was quickly brought into the Marvel universe and her importance has continued to increase ever since. For one, she recently made her big screen debut in Logan.
Created as the perfect killing machine, Laura worked as a brainwashed assassin before she crossed paths with her father and the X-Men, who rehabilitated her and set her on the hero path. With Logan’s regenerative abilities and retractable claws – Laura has two on each hand and two on each foot – X-23 is every bit as fierce and deadly as her dad.
She’s also one of the few super-kids to have successfully replaced their father’s mantle: with Logan dead in the comics right now, Laura’s the current Wolverine. And with Hugh Jackman hanging up his claws after Logan, Dafne Keen could be about to follow suit in the movies at some point in the future.
