Crookedstar. I also like Mistystar and Stonefur. I detest Leopardstar....in my opinion she gave RiverClan a bad reputation and I'll never forgive her for what she did to Stonefur.
Crookedstar, Mistystar, and Feathertail; Stonefur and Stormfur are awsome, but not my favorite; I like Leapordstar as a character/warrior, but she FAILS at being leader!
