::: That index is not notable by itself. However, including an index-format for one-off characters within this article is fine, because this article is already notable, and WP:NO 	 ILITY only applies to whole articles rather than specific sections or statements within an article. For content, there is WP:N#NCONTENT, and this would not give undue weight to these characters. Please stop removing the list of one-off characters, as there is no policy or guideline that supports you, and the value of this list is supported by WP:LISTS.
