He keeps changing his party because he only uses the pokemon found in the wild in the area your in.Xman490 said:Ridiculous Element of Black and White #69: The Plasma leader is named N, is schizophrenic (says stuff like, "Let me hear the voice of your Pokemon!"), poses like a ******, keeps changing his party, and preaches about segregation.
Seriously, he catches them to fight you and then releases them. Also not so much schizophrenic as he is emotionally unbalanced what with the whole being raised without human contact surrounded by abandoned pokemon so that he grows up to think that all pokemon are miserable.
I mean yeah he poses like a fairy and is perhaps one of the most annoying characters in the series, but cmon people target things that are actually wrong not wild misinterpretations.
