She initially both disliked and fear the pokemon in the type but she's grown to become used some of them over time. Even if she's grown to accept them, somewhere in her mind is the belief that the ghost members of her team would turn on her and attack her for the hell of it so she kind of avoids adding ghost pokemon to her team. There's currently one member (Kizu the Banette) that she's caught so far but technically, he kind of followed her the whole time she was possessed by a Yamask and she let him stay because she felt if she tried to ditch him, he'll come back and kill her.

Speaking about Yamasks, she kind of detests them because possession was something she wanted to avoid both here and back home. The only Yamask that she's ok with is Envy's Edmund after that whole Yamask possession event.
