That's a lot of stuff I can't claim to have there Prince personally I just go with what I got after thinking of a main 'villain' without making him a complete dick and giving him a plausible reason or making him just down right insane joker style for doing what he does. Mercs, revolutionaries, and or mad scientists are normally my A game. 

A big thing that ticks me off is when I do thing to improve roleplays and then others claim I'm being one sided because I don't want others to use them. I make some powerful characters or multiple characters with specific abilities or back stories in order for the roleplay to have a solid base no matter what the other characters are. If there was more than one of them then it'd unbalance the roleplay but since I'm not the guy who's going to be called out on being unfair I normally try to talk people out of it to little success. I mean I manage more then five characters per scene at times I don't exactly enjoy doing so but do it because I want to see my main character advance and if I did so in another rp and left it that leaves a large mass of characters just sitting there and getting them out if it is say an important scene is awkward.
