Hey, welcome to SNN. Let me give you a few quick tips on categories.

First of all, even though we have Mario characters on the wiki, we don't give them categories such as "Mario characters". We just settle for Crossover characters and nothing more.

Secondly, when you want to give something a category, make sure that it is not already a grandparent category. Categories can be categorized themselves. For example, the category Alien races is categorized under Species. And as the Wisp article already has the category Alien races, it does not need Species.
