In fiction (stories that are made up), the character is an imaginary person with a personality, and what makes up a character's personality is called characteristics, or if you really want to sound fancy, characterization.
The personality of a character is shown in several ways:
- how he/she is described by the author (writer of the story)
- how he/she acts
- what he/she says and the way in which he says it
- what other characters say about a character
