Roy Greenhilt. I can't even remember the resistance leader.

Gortok, for he has more personality and power than Banjo, who must gain his power from his followers.

Malack because I can't help but like intelligent antagonists. 'Kaboom' was alright in his own way, but not memorable enough to stand a chance.

Daigo Da-, mainly because for some reason the cops didn't interest me too much. Well, neither did Daigo Da-, but a little more so than the latter.

Also, of the four characters who are doomed to lose, I think that Gortok will make the strongest showing. He even made an impression on Belkar, so that must mean something.
