2) X-23 And X-24
Logan gains a daughter of sorts here, in the form of Laura AKA X-23. In the comics, Laura takes on the mantle of Wolverine after he dies, so it’s entirely possible that we haven’t seen the last of her.
Laura’s backstory, being experimented on by Rice but being cared for by one of the facility’s nurses, is taken straight from her comics origin story X-23: Innocence Lost. In particular, the scene where she cuts her own arm with her adamantium claws is pulled right out of its pages. Similarly, the image of Laura on her knees with her claws out recalls the cover of NYX #4.
Logan is also revealed to have a second fully-grown clone, named X-24. The character is original to the film, but the unseen X-24 project was mentioned in Innocence Lost, being destroyed before it was unleashed. There have been other evil Logan clones in the comics, too, including a zombie and a robot. It might be a bit of a stretch, but there’s also a certain similarity to Daken, Logan’s evil son from the comics.
