Haya! That is happening because Template:Infobox (Character), called directly or by the redirect Template:Character Template contains the command (last line) to place the page it is called on into the Category.

Remove the line, or better still comment it out by wrapping it inside

Another way to prevent the line from placing pages in the category is to place a colon just inside the opening brakets and at the beginning of "category". Thus Category: Infobox Templates

Check the other templates also in that Cat for the same thing.

Incidentally, as the category was not formally created, once that command line is removed or negated, the category page will self-delete.
