Recently I noticed that four articles on my wiki are under the Templates category, though they are jut regular articles: http://marveltsumtsumgame.wikia.com/wiki/Category:Templates (the first four pages, starting with Heroes for Hire)

How does the wiki determine whether to add some pages to the "Templates" category? Can I remove this category from the articles?
