Always looking for new options to polarize characters. your intrepid Jack has discovered the writings of Coryelle Kramer whose speciality is animal communication. Ms. Kramer has identified what she considers to be six animal dynamics. Look at her list here:

• The Direct & Demanding
• The Rule Breaker
• The Energetic
• The Sensory
• The Shifter
• The Transcendent

Now consider what they may mean. You may have different definitions, but I glean the following.
The Direct & Demanding dynamic would be someone who needs to have action and responses right away. Patience is not always their friend.
The Rule Breaker is always looking for a quick and easy answer and sees rules as a way to confine their ingenuity. Or maybe they just see it as a way to crush their spirit.
The Energetic is always looking for the next adventure. Endlessly filled with curiosity and vim and vigor, the Energetic might very well wear down the best of us with a thousand different active projects.
The Sensory is your introverted and empathic character who is aware of the “energy” and mood of a room and the people around. Soulful and sensitive.
The Shifter is a character that transforms all ideas and energy, shifting from one mood to another, one idea to a better one, or a more reckless one. The Shifter could be a random character with quixotic ideals.
The Transcendent is a deeply spiritual character who seems to be beyond the mere rabble of the world. Seeing beyond the veil of this rude world.

So those are six new possible ways to polarize your characters in your story. They certainly are a way to make sure they all react differently to each other, aren’t they?
