Emotion

An emotion is a physical representation of a person's feelings, such as anger, joy, grief, or sadness.

Appearance
The emotion's appearance correspondingly reflects the person's feeling. For example, torn clothes is an aspect of grief or turmoil, as clean and fancy clothes can represent happiness. The expression on the emotion's face parallels the feeling it is representing.

The emotion's hair will always stay the same, just in different hairstyles or patterns.
