2) The Feeler
If you want to really torture your characters, force Dick and Jane to work in tandem
3) The Ditherer
4) The Pacifer
5) The Obstructionist
6) The Despot
Some characters are born to lead, or push, shove, and bully everyone else. Sally has no doubt that she is right and everyone else is wrong. She will not tolerate being questioned. Her beliefs are often based on vague assumptions with no backup or foundation whatsoever. It won't matter. She will take charge and steamroll the passive-aggressive, the ditherer, and the pacifier. She will fight to the death with the obstructionist and the ponderer.
Characters forced to make painful or life altering decisions can serve as an overall story problem or complicate it as part of their personal dilemma.
