When creating Objective Characters in your story, character elements can be combined in just about any combination you can think of. The further away from archetypal characters you make them, the more 'interesting' they may seem to your audience (they'll be less predictable). One 'rule' to follow is to avoid creating characters that contain both sides of a dynamic pair. Another recommendation is to put the MC crucial element in the objective character (player) that is also the MC, and the IC crucial element in the objective character (player) that is also the IC.
