ashfur and crowfeather are pretty high up there for me. i used to like them both (especially crowfeather) but that changed for reasons stated above.
i really disliked squirrelflight when she was first introduced, then grew to like her later, and now i'm just. eh. not really taken in by her anymore i guess. firestar was similar – liked him a lot but gradually stopped as the series drew on.
oh i also reeeaally disliked sol. i wasn't even that intrigued by him, i just wanted him to Stop
