The Support

Not to be confused with the other kind of support character, secondary characters who help the story progress by interacting with the main characters.

The one who aids the main characters through their adventure to some meaningful extent. Their help can be lent to the Good Guys directly or indirectly. If the Support is helping the main character via direct contact, then they're likely to be one of the Good Guys and at the Hero's side most of the time, giving pointers on how to be better at what it is they do or lending a hand in battle. If this Support is helping indirectly, they could be sending resources (like food or money) to the Good Guys from a distance as they're out on their journey. A Support does not always have to fight in adventurous stories. They can be a Healer who stays out of the action and who injured fighters on their side report to when they need medical attention.
