Character Transformation
Personal transformations are always at the heart of strong character arcs. Our protagonists are faced with trials that force them to acknowledge their own inadequacies and then, usually, change their ways in a manner that allows them to overcome both their faults and, as a result, the bad guy.
— K.M. Weiland
