Please be careful with the use of categories. An abusive application of categories kind of make them pointless, as too many pages are included to make them comfortable to navigate. And such categories as "Main characters", "Secondary characters" and "Minor characters" must not overlap on a same page.
Otherwise, also please be careful about the spelling. There's already a category named "Shantae: Half-Genie Hero", so there's no use in creating a "Shantae half genie hero" category, which is also misspelled. People do care about grammar and typography, as they may not be willing to read stuff that looks amateurish. A wiki is not a forum or reddit!
