User blog:SolZen321/Double Categories

I have notices that several pages have categories such as Alien, Aliens and Seijin, is there a reason for so many categories that synonyms of each other, such as 'Monster' and Kaiju. I can understand subcategories such as Ultraman Tiga Kaiju and Kaiju but why do we need to do something about those redundant categories. Also, why are some of the aliens 'Monsters' all of a sudden, 'Monsters' are category for creature of lower intelligence, like animals, I can understand Alien Regulan being in the Ultraman Tiga Kaiju category but that's only because the category is shortened, it really refers to any none human or Ultra beings in the series. I really think we should do something about this. SolZen321 (talk) 23:56, June 3, 2013 (UTC)
