You can protect your pages from vandalism unfortunately I don’t know how though.

@PortablePortal I have protected the pages to Autoconfirmed Users, but I still want some users to be able to edit it if they know how to improve it, still keeping the ability to disallow the ability to do so on a specific character page.

And you can even set up an AbuseFilter to ban one user from one type of edit, but that's not really the feature's purpose.

@SpeedoThreeSixty id say then restrict editing to only administrators

And you can just tell them not to do it, and if they don't, block them.

@PortablePortal I think telling them not to do it and blocking them worldwide for a bit could do, but if I were to do your suggestion instead, I still want users to be able to suggest edits to the character pages. How'd I set that up?

You could make a new caragory that’s named something along the lines of “Character Page Edit Suggesttions”

TreeIsLife, I believe you can do that on Fandom wikis too. I am guessing they are just using Titleblacklist. Either way though, it doesn't do what SpeedoThreeSixty wants; which is to block a specific user from editing a specific page.

If users want to make suggestions of edits, they can use the talk page and/or the comments. Let's assume the page is called Example. Then its talk page would be Talk:Example.

OK, I'll just go with restricting the pages to administrators, the warn-then-block system will just be used for any other page.

(AKA, solved.)
