The one problem with the category is that Paula also learns it, and other people might as well, so I put it as Mother PSI. --Karis 02:39, 29 March 2009 (UTC)
 The thing is...
What Paula uses is PSI Fire, which is different from PK Fire. So they would have different names. Besides, even if this were in two games, Mother PSI is basically the Mother/Earthbound Zero game. There can be more than one category on a page anyway.
