The move will most likely be carried out by a bot. It will move all content from X-23 to Laura Kinney and redirect X-23 to Laura Kinney. Then a user will remove all none Laura related stuff from Laura Kinney and create a new X-23 page. It'll look similar to Prowler or Psylocke.
You don't actually need a bot to do it, since the links to both terms should remain links to those separate terms, you simply need to rename X-23 as Laura Kinney(be sure to check the boxes to rename the talk page and any subpages and uncheck the box to leave behind a redirect) that way the edit history remains with Laura's disambiguation per Fandom's ToS, and then you can remove any content that's not specific to Laura and build a shared mantle hub disambiguation at the vacated X-23 address.
So does this mean X-23 is actually going to be moved then made into a hub? Because I'm pretty sure that most people on the talk page were against it and no one really said that they do agree with it unless there was a voting that I somehow missed. Also I don't think that the Others and Related sections are worth splitting up for this and they can easily remain as they are.
