In response to your question, it is because the Kaijin category had been abused, as it was made for the MOTWs (Mosters of the week) to seperate them from the main villains. As it stands, that did not hold up as main villains began to get inserted into the category as well. In order to make it more clear that those in the category are just MOTWs, we will now be using the terminology of RangerWiki, Metal Heroes Wiki, and the rest.
