Kerrigan
I rly liked her character as a human, always full of life and energy (my fauvorite char along with jim) and when i was playing through whole brood war i always hoped she would change back somehow ...even when she told overmind lost control over her, i was happy, that she was turning a bit to her old self, but was dissapointed when she was still that bad ass ... i don't think that this role suited her too well... she's not a good choice for a bad guy imho ... i hope she'll be turned to human in SC2 :) ... and jim won't have to kill her :)
I used to be a schizoprenic. But now, we're fine ... :)
