That’s a very interesting concept. It may be difficult to distinguish between, say, the one representing logical-mathematical intelligence and linguistic intelligence (you might be tempted to make them both “nerds” because, well, they represent intelligence), so keep that in mind. Here are some ideas I have for traits for each character.

1. Naturalist Intelligence (nature, living things, natural world, society) – political, argumentative, conditional (“what’s in it for me?”), absorbed in pop culture, compassionate, stands up for what they believe in, not easily swayed, loyal

2. Musical Intelligence – rhythmic, distracted, perfectionistic, sprightly and cheerful, stuck in routine, gets along well with nearly everyone, possibly a bit moody

3. Logical-Mathematical Intelligence – loner (happy to be left alone), fast-paced, addictive, reckless, narrow-minded, reliant on first impressions, impatient, balanced, efficient, punctual, caring

4. Existential Intelligence (human existence, deep questions) – absent-minded, brooding, accepting of others, a friend to all, lonely, cynical, intolerant of shallow people, easily annoyed, sees the “big picture” rather than paying attention to detail, forgetful

5. Interpersonal Intelligence (understanding and interacting with others) – social butterfly, shallow, judgmental, lots of friends, talkative, empathic, sympathetic, adaptable, relatable, curious

6. Bodily-Kinesthetic Intelligence (not only athletics & sport but also mind-body union) – careful, precise, thinks before they act, a planner, physically fit, vain, aloof

7. Linguistic Intelligence (thinking in words and expressing things verbally) – curious, nosy, talkative, uncomfortable with silence, restless, active, compulsive, can be overwhelming, enthusiastic

8. Intra-personal Intelligence (understanding of oneself and own feelings) – emotional, self-absorbed, self-reliant, critical of others, narrow-minded, independent, determined

9. Spatial Intelligence (mental imagery, imagination, spatial reasoning) – creative, artistic, appreciative, needs “room to breathe”, particular, snobby, imaginative, odd
